I recently got this second (actually 3rd) hand 2003 R1000 with a tad over 10000 miles on it. Beautiful machine, I love it.

It has synthetic oil in it.

I have never used syn oil before so I am a bit in the dark with a few questions.

1) Mechanics at the Suzuki dealer say that if I switch the oil to the conventional type this will create problems with the clutch to 'slip' (not sure what they mean by that).

2) With conventional oil, I used to drain and refill when came winter storage time, then do this again at spring time but that time I would replace the filter as well. If I stick with syn, do I do the same or can I change the oil+filter at storage time OR when I take it out of storage. Obviously I would hate trashing a full load of syn that has not been used except for 'being there'.

3) If I stick with syn, I will probably use Mobil 1 10W30 meant for car engines. I would prefer 10W40, but it does not seem to make in this category and I can't find the MX4T category around here (and honestly I do not beleive in the added value of a 'motorcycle oil'). I don't live in Texas, average temperatures are below 30C, with a few exceptions, times when I avoid riding as I find my gear and helmet unbearable.

Pennies for your thoughts.

Send your pennies via paypal, please. :D

Find a new dealer right away. Jeez, these guys never cease to amaze me. You can switch to conventional oil any time with no real issues. In fact, you can buy blended oils every day of the week. It will NOT cause you problems. However, it WILL change the way the bike shifts. I won't use synthetic oil because the cost is just not worth it.

Having said all of that, I wouldn't just indiscriminately blend my own synthetic/conventional oil. There's a science to doing it.

2) With conventional oil, I used to drain and refill when came winter storage time, then do this again at spring time but that time I would replace the filter as well. If I stick with syn, do I do the same or can I change the oil+filter at storage time OR when I take it out of storage. Obviously I would hate trashing a full load of syn that has not been used except for 'being there'.

Put it into storage with the conventional oil. You're not going to cause yourself any problems.

3) If I stick with syn, I will probably use Mobil 1 10W30 meant for car engines. I would prefer 10W40, but it does not seem to make in this category and I can't find the MX4T category around here (and honestly I do not beleive in the added value of a 'motorcycle oil').

I see it on motorcycle boards all the time and I struggle to edumacate people of the basic fact: There is no such thing as "motorcycle" oil. If you buy "motorcycle" oil, you just got ripped off for $5 to $10 per quart. One of the bigger scams in our sport. I saw a gallon bottle at the dealership the other day for $40. I buy it at the auto parts store at $11 for a five-gallon jug. Can I get a "Hallelujah?" Amen, brother! (No, I'm not religious! :D )

There are, however, differing grades and blends of oil. If you use what's recommended in the owner's manual, you will NOT go wrong. Change interval is 3,000 miles, regardless. Also, I don't think I've ever seen a 10W40 synthetic. The 10W30 is fine for motorcycles.

Make sure you don't use oil with friction modifiers or oil labeled with language like, "enhances fuel economy," or such shit. That stuff WILL interfere with your clutch operation.

Good luck. Keep us posted.

--Wag--

Thanks Wag, I like what you say and see eye to eye with you.
I just got back from shopping but I had not read your reply to my post prior to leaving, I would probably have had (again) serious second thoughts about using syn had I read it.
I found at Walmart's Mobil1 MX4T which is synthetic 10W40 'engineered for motorcycle ...' right ...
It's expensive and I don't think it is worth what is costs, $ 15 a litre, damn.
But that's what's going in this time. I'll store the bike with it in it in a bit less than 3 months from now. I'll make sure to make it idle about once a month all throughout the time it is stored. Since this oil is good for 1 year/at least 10000 kms, I wont' replace it until it reaches one of these terms.
I'll keep reading and collecting people's own experiences on this topic and may elect to go another route the next time I do an oil change.

Thanks for you input, very much appreciated.

3 months? Put a battery tender on it and some fuel stabilizer in the tank and forget about it. Just starting it for a few minutes is not good...

I buy Repsol only :punk

and enjoy getting ripped off cuz I get a free tshirt or free cast iron Repsol replica bike - last one I got was Nicky Hayden's RC211V 2006 - I play with it on my desk at work - vrooom vrroooom

I store it for winter in 3 months, but for about 5 months though.

heard ya the first 2 times lol

Have to agree with this.

Just so you know there is a such thing as motorcycle specific oil and it does make a difference. First the oil in most bikes has to work in three key areas 1 the engine itself 2 the transmission 3 the wet clutch, these motorcycle oils are formulated with specific additive packages to provide proper performance in these key areas. Most automotive type oils are not up to this task for several reasons......... i recommend amsoil 10w 40 motorcycle oil and yes synthetics are available in most all weights including the 10w 40 the manufacturers recommend. Many have run non motorcycle specific oils in there bikes and have had no failures. I feel for maximum equipment life and best performance a motorcycle specific oil is the best choice. Perticuarly the amsoil 10w 40 motorcycle oil. Best of luck hope this helps you to make an informed decision

Use fuel stabilizer when storing. As for starting it in the winter i recommend that and do the same with mine the key is to run it every couple weeks (IMO if an engine sits for a large period of time eventually most oil will drain back to the pan and there will be little oil left coating critical parts in motors top end creating almost dry start conditions when it is finally ran) for at least ten to 15 min at a time when it is started to keep battery charged and also to get engine temp up to full temp for several min this will drive out all condensation and moisture. Hope this helps as well best of luck

Thanks pafunid.
As I stated yesterday, M1 MX4T is my choice for now. It is a an oil that is so to say formulated for motos and has good reviews all over. I found Amsoil here too, at Walmart again. I was going to get that, but I decided in favor of M1 when I saw that Amsoil sells for $ 20 a quart. I don't think of myself as cheap, but I think one should be sensible with money and this is to me a rip off.
But this is no news, everything is more expensive in Canada than in the US. We should have a slogan that says "Come to Canada, we'll rip you off good".

I'm at 65,000 miles so far.

I have issue with the "I feel" parameter. Unfortunately, making buying decisions based on "feelings" gets us all into trouble. Why we have bikes in the first place! :D What I've yet to see is any conclusive study that shows that "motorcycle oil" is in any way superior to any other oil out there.

You also said, "these motorcycle oils are formulated with specific additive packages to provide proper performance in these key areas" but you don't say what those additive packages are and you don't give an explanation of how these mysterious packages work.

Lastly, you said, "Most automotive type oils are not up to this task for several reasons" but you didn't give any reasons at all.

Genuinely, I'm not trying to be a brick here but in all of my reviews, I've never seen any better answers to these questions than what you just gave. In other words, none at all.

Which is to say that as it stands, your comments are without authority.

But, I'm open-minded and willing to learn. If you're right, I would love to know that so if you have any links to some info to back up what you wrote, I'm all ears. Er, eyes. :D

Thanks, boss!

+1 on using fuel stabilizer when storing.

-1 on starting it every couple of weeks.

Bear in mind that idling a bike isn't going to charge the battery. It has to actually run at a higher rpm to charge it. Best thing is to use a trickle charger.

If you read the owner's manual on how to store long term, it tells you, among other things, to pull the plugs and tip in a half teaspoon of oil into the top of each cylinder. That will eliminate the concern for the oil draining into the bottom of the engine and causing problems when restarting. Further instructions for taking it out of storage follow in the manual.

Which actually works.

--Wag--

Whatever you do, NEVER switch from conventional oil to synthetic or vice versa.


In other words, once you put one kind of oil into the bike, that is the only oil you can ever run through it again.....EVER.......FOREVER.

A comparison of Mobil 1 15w-50 automotive car oil against its V-Twin 20w-50 motorcycle oil doesn't show increased levels of additives...

They summarise...

"So what about the Mobil 1 oils? Are they all the same? Graph G compares only the four Mobil oils for each of the five additives. Note that the first three oils, the higher viscosity ones, are all closely grouped. It is the opinion of the author that the additive packages in the old Mobil 1 SH, the current SJ, and the new motorcycle-specific SG/SH are all the same. The Energy Conserving Mobil 1 SJ has lower levels of all additives with the exception of magnesium"... ..."Mobil 1 motorcycle oil: is it worth buying? The viscosity of this bike oil has been changed from Mobil 1's standard 15W-50 to 20W-50. This just happens to be what Harley specs for their bikes. If you smell a marketing ploy here, you may want to trust your nose. The additive package appears the same amongst all the 50 weight Mobil 1 oils"

dipkiwi, it's like my law professors always say: Follow the money.

Something I've always said. I like the presentation of facts. Got anything else? I'm especially suspicious of Amsoil.

--Wag--

i used the wording i feel to soften my response.
sae tests is one source of such information to prove motorcycle oil supperiority in that application. most automotive oils will not meet the standards required to pass these motorcycle oil specific tests
another is the min standards for oil set by the japanese motorcycle manufacturers again most automotive oils will not meet these basic min standards ever heard of jaso? how many car oils you know meet jaso anything let alone the highest jasoma2 rating?
amsoil has done comparison testing even against other motorcycle specific oils using sae testing methods and has done a very good job of demonstrating its products supperiority.
additive packages for motorcycle specific oils do not contain various energy conserving type friction modifiers and contain generally much higher levels of ep additives a few such as zinc phosphorus someone mentioned above but there are also others that are in the additive packages specific to motorcycles and are essential for maximum transmission and valvetrain protection plus base stocks that are shear stable so they can take the transmission gears stress on the oil with out degrading. pull an oil sample and send it off after 3000 miles of regular use in the bike most likely it wont be at the same grade it was when it was new showing inadiquate sheer stability in your application.
there is info available to educate yourself and that will go into much further detail than my limited knowledge can provide if your truely interested. anyhow yes there is a difference. may not be a great difference as some of the high end car oils contain very robust additive packages as it is with several additives that are common for both applications.
my specific brand of motorcycle oil even meets requirements for sae gl1 (a gear oil rating) can you name some car oils that meet that? Few if any can.
automotive oils only have to protect the engine and are formulated accordingly motorcycle oils have to be a jack of all trades and protect the engine the transmission and not interfear with the wet clutchs operation.

Just to be clear, I'm not saying you're absolutely, incontrovertibly wrong but I find it notable that you have give ZERO specifics.

Until you do, all of the claims you're making are highly suspect.

Not because I haven't done my homework because I have. I'd like to think I've missed something out there but you haven't convinced me.

You'll have to give some specifics. Thus far, it's been a wild goose chase for me to try to substantiate your assertions and I'm done doing your homework for you.

Bottom line is, I have never found any reason to think that "motorcycle oil" is even clearly definable.

Put up some links, man. We're starving for details.

lol did you even read what i typed and or did you understand it?
in sae testing the fing car oils do not meet the basic motorcycle specific sae tests peroid look no further end of story. obviously they must be different if the motorcycle specific oils do and the automotive oils dont. not to hard to understand tests have proven this.......
rotella a heavy duty diesel oil carries the rating and it is not motorcycle specific (but still cant meet jasoma2) as for your basic car/automotive oils they do not and most are energy conserving.

and as for other guy posting the different mobil one oils additive compositions where can you buy mobil one with only sg rating the new stuff is sm? lol sg is really old. i ask because the sm rating required substantial reductions in the levels of zinc one of the main ep additives(search hotrods flat tappet cams the new oils have been killing flat tappet cams). and all the current automotive oils within the last few years are sm.....

Yeah, I read it.

No, there are no references to ANY source.

You do know what a source is, right?

In other words, prove what you're saying, otherwise, you're just posturing with the same bullshit any other faker pulls when he doesn't know what the fuck he's talking about.

Which is really what I'm thinking you're doing here.

--Wag--

this is a waste of my time i will not post on here anymore anyone who can read will understand what i have said.

for one thing you didnt even know synthetic oils were available in 10w 40 weight go read your earliest posts on this thread yeah you said that.....this pretty much tells me the extent of your "research" and "knowedge" on oils

car oils do not pass the testing required to receive a jaso rating that motorcycle oils do. if there is no difference they would both be able to pass.

i could go on but why bother i know some of the basic differences and again testing has already proven it. to argue with you at this point is just rediculous

this is a waste of my time i will not post on here anymore anyone who can read will understand what i have said.

Well, that was predictable! :lmao

Yup. I didn't know. I was looking forward to see the research you had done about it because, as I said, it's been a while since I've updated. Obviously, however, you don't have any research of your own to back up what you're saying.

Tragic that you have an opportunity to assist and educate but you blow it off as "a waste of your time."

car oils do not pass the testing required to receive a jaso rating that motorcycle oils do. if there is no difference they would both be able to pass.

Still making assertions without substation. Are you ready for it? Here it comes: BULLSHIT!! :D :D

You're right. You don't have any backup for your opinion. You're just spouting crap you've heard at bike night somewhere. Heard it before too. Did the homework when I heard it. Didn't find anything to back it up back then either and neither can you, obviously.

BTW, have fun blowing excess cash on overpriced "motorcycle oil."

--Wag--

I'm gonna have to agree with wag on this issue, Your statements are on the standard of "I've heard this, I believe it" Or the famous "He said, She said" You've said in so many posts "Tests have proven" What test? Tested by whom? When? Were? The results? Send us a link?

When debating theres a few common things to keep in mind.
If your giving a statement like "tests shows blah blah blaa" You add (www.testforbla.com) to it. Or atleast copy/past the data sheets or a screen shot.

I trust alot of the members of this site with many issues, But I always cross check there information across other sources I can find.

And to just help everyone inform themselves (I know I just learned alot!)
http://www.nightrider.com/biketech/oiltest1.htm

The results of these tests seem to support some of the long-standing theories about oils while casting serious doubt on others. Going by these tests it would seem logical to assume that:

1.The viscosity of synthetic-based oils generally drops more slowly than that of petroleum-based oils in the same application.

2.Comparing these figures to viscosity retention for the same oils when used in an automobile (see later text by Prof. Woolum) would indicate that motorcycles are indeed harder on oils than cars.

3.The fastest and most significant drop in the viscosity of petroleum-based oils used in motorcycles occurs during the first 800 miles (or less) of use.
All of these results (1-3) agree with everything the oil companies have been telling us all along. However, the same test data also indicates that:

4.The viscosity of petroleum-based oils, whether designed for auto or motorcycle application, drop at approximately the same rate when used in a motorcycle.

5.There is no evidence that motorcycle-specific oils out-perform their automotive counterparts in viscosity retention when used in a motorcycle.

These last two results (4-5) definitely do not agree with what the motorcycle oil producers have been telling us. In fact the test results not only indicate the two motorcycle oils being outperformed in viscosity retention by the two automotive synthetic products. but even by the relatively inexpensive Castrol GTX, which is a petroleum product. This directly contradicts the advertising claims made by the motorcycle oil producers.

Read the full aticle there. And let this end this debate once and for all. or untill the next generation of oils come out?

Slight disclaimer, this is from 1994 research, Might not be valid for newer bikes. I'll continue to research on this topic for a more updated study. Since this falls into my 1994 GSXR1100 it's a valid answer, But for a newer motorcycle, it might change slightly. back with more info soon.

Here is a 2009 study done, with easy to understand graphs and explanations. It's PDF file, So you will need to download it, or have firefox to view it in a new window. Enjoy the read.

Nice, Kazumi. That second link didn't work for me but I have script blocking turned on and I'm sure I just have to figure out which one of their 2 bazillion scripts needs to be switched back on! :D

I quickly browsed the first link and will read more of it later.

Thanks.

--Wag--

I sure did not have in mind to make two people with obvious strong different beliefs confront when I launched this thread. The outcome though was quite educative.

Sadly enough though, I did not get any facts with evidences to back them up that I could indeed switch to conventionnal/petrolum/mineral and stay away from problems with the clutch or God knows what else, and this still is my main concern. I realize what effect marketing has on me : It makes me dread I can dammage my beloved bike and might have to spit out lotsa money in result of behaving in an uninformed/ignorant manner.

But what can I do, I am no mechanic nor chemist, I have to rely on what I can find out from all sources. When statements/opinions consistently go in diverging directions, I remain half way inbetween the extremes, still doubtfull.

One thing is now crystal clear in my mind though : If my bike had not have syn in it, there would not be ever and, what would go in it would not be the so called motorcycle specific product..

Read the links Kazumi posted and see what you think.

that was one of the reasons i mentioned in an earlier post that those mobil one comparisons were very dated and not too relevant with most of these current (sm rated)automotive oils.

ten years ago i too would have been running a NON motorcycle specific oil on my bike but with todays oils this is not the case.

There is tons of info in magazines and books and info available on the internet. Most of this info has reinforced my decision to run a non automotive specific oil in my motorcycle. If i did have to run a conventional oil and of non motorcycle specific i would highly recommend rotella 15w 40 BUT even that good quality heavy duty diesel oil would be inferior to the oil I am running currently (amsoil 10w 40 motorcycle oil and several other synthetics i would choose from before the rotella) Perticuarly in the high stress environment of dragracing which is what my motorcycle sees primarily on occasion it will be taken out for a brief street ride.

My point in this is and has always been there is a difference in motorcycle specific oil formulations verses automotive specific oil formulations. Ask via email or phone the oil manufacturers and they will tell you this and there the ones making the oil so they should know if anyone.

Indeed they are making it, but selling it too.
It seems that whenever it comes to oil, whether it's to lubricate or to propel, 'they' are not that transparent. So I have a problem asking 'them' for advice.
I agree with you that there are differences inbetween motorcycle oil vs car oil, I do not debate that, nor has anybody. But the question remains, are the differences actual added value to you and me or is it to the oil maker's profit margins.

Pafundi, that's exactly what I'm talkin' about. I have the links up and will get to them.

Much appreciated, man. Seriously.

Bear in mind, I still have my biases, however, at least I know they are there and can recognize them when I brush up against them.

You did mention the high stresses of drag racing. I'd have to agree, a much more focused approach to what you use in such an environment is required. Even the track day I went to I took the extra step of changing the oil out after the first day which is something that was completely anathema to me. But it seemed like the right thing to do.

Anyhoo, thanks again for the links. Genuinely appreciated.

--Wag--

I'm just going to go to Cycle Gear and buy the cheapest 10W-40 or 15W-50 oil they have :dunno

Here's some more reading... I've used Shell Rotella with great result on my old SV1000 and for breaking in my GSXR. I've switched to Castrol Synthetic since but it doesn't seem any better than Rotella; it just seems to go a few miles longer.

link: http://www.cb750.org/techtips/movsao.htm

I found at Walmart's Mobil1 MX4T which is synthetic 10W40 'engineered for motorcycle ...'

I am unsure what the bikes are like with drinking oil, but I know on my s2000 that the engine loves the taste of the mobil 1 stuff... just something to maybe keep in mind when picking oils...

Amsoil is some sexy stuff, it's a bit pricier but very nice!
