What oil do you use and how long do you leave it in before changing?

Mobil 10W-40 car oil, change at around 3-4K miles. I have an oil-cooled bike, when should i change the oil?

I use Repsol semi Synthic and I change it every 4k miles.

Unless you have something in writing from the oil manufacturer, or use Oil Analysis, you should not exceed the OEM Recommended Drain Interval. The OEM's list the Maximum number of miles under normal driving conditions. Hard driving and Racing will break an oil down sooner.

This is not saying that your oil is not serviceable after that mileage, but without the proper testing (Used Oil Analysis) there is no way to be sure. UOA can also let you know if there are internal problems with your bike by supplying wear metal counts, and also if you have either an air leak or improper air filtration by silica counts. UOA can be used to give you a baseline for oil change interval.

repsol racing 10w40. change every 3 trackdays.

4k miles is the from the manual ... it says to change the filter every other oil change but I do it every oil change ...

repsol 10w-40 changed every 2500 miles.

i was asking because between cars and bikes its been around 3-4K mile oil changes probably ever since they were doing oil changes. Oil has advanced since then but the interval has stayed the same.

shell rotella t. maybe every 5-6k if its lucky. blackstone labs says the oils still good. the amsoil vtwin formula i was using before was dead at 2-3k. lighter amsoil made my bike valvetrain real noisey and gave notchy shifting. rotella t in everything i own now.

Golden Spectro and I change it every 2500-3000 miles

repsol 100% synthetic 10w-40 every 3k.

up til last month i've always run Honda's HP4 synthetic blend (gold container) 10W-40

but experiencing degraded performance from this oil, now that I utilize the FULL POTENTIAL of the bike.

I have since switched to AMSOIL (full synthetic) 10W-40.

I have always changed my oil every 2000 miles (sometimes within 1800 miles if rode hard)
but the K&N filter only gets swap'd every other oil change.

it's worth the cost to avoid oil degredation and premature engine wear.

Amsoil, have used it since around 00'.

Before that it was Motul.

use Motul 300v change after TD or every 1000k

Royal Purple Max Cycle 10w40. every 3000 miles.

I use Motul Full Synthetic 10W-40 and change it every 3,000 miles along with a new filter.

The only comment I hear consistently about Amsoil is that it gives a less positive feel to the clutch/the clutch feels like is "slips" a bit more than with other motorcycle specific oils. Otherwise... I've heard good this about Amsoil.

With personally having a couple thousand customers that I have sold AMSOIL to, and Suzuki Owners being my largest customer base, and with AMSOIL having a JASO Rating of MA 2, I would have to believe that is a myth.

Even Sport Rider Mag has reported that if a M/C Specific oil is used, there is no problem with the clutches that will be caused by the oil. It will be due to weak springs, clutches or possibly an improper oil used previously.

How did you determine that the oil was dead at 2-3k? I have never seen any brand of oil dead at 2-3k unless an internal problem contributed to trashing the oil.

i run motul in my scooter, valvoline in my car and s-10= change at 3000 miles
i use amsoil in my duramax=change at 30k.

why would you need to put oil in it? doesnt the bike come with oil?

fully synthetic astroglide!

My comment about the clutch feel is simply based on what others I ride with have stated as their impressions. One of these people is a top ranked stunt rider ... who happens to be sponsored by Amsoil. He likes the Amsoil but also feels that clutch engagement feels less responsive. Again...only passing on impressions.

shell rotella t 15-40 around 3-4k Usually when I change my tires... and filter every other time.

Extra Virgin Olive... I didn't know you have to change it...

but really, Repsol 10w40 full synth, every 4k, 5k if I am lazy... new filter every time, mixed light commute and hard riding, a couple trips to the 1/4 mile.

Amsoil, in both cars, truck, and my bike.

royal purple max-cycle full synthetic here. 10w-40...

change it after every 2 track days or one complete race weekend.

even after reading the test results, i will still stick with my royal purple. my k3 1k had well over 50,000 street/track miles on it without a single problem, and i used royal purple in it from about 2,000 miles. same with my k6 1k, switched to royal purple at 2,000 miles agian, and i am sure i will see another 48,000+ without issue.

but thanks for the great reading, and congrats on winning the test.

:cheers

"motorcycle oil" to me, is a waste of money. I also use rotella or delo 15w40. Don't believe me,read a test done by Motorcycle Consumer News,an un-biased and no advertising magazine that tests products. http://www.xs11.com/stories/mcnoil94.htm.

That is because you are digging up and looking at a 14 year old article..Keeping the Myth alive. In 1994 SG/SH was the current rating for oil, friction modifiers were virtually unheard of and there wasn't a lot of difference between Auto and M/C oils back then.

Oils have changed in the last 6 months, much less 6 years or the 14 years since the article was written. ZDDP has been reduced or removed from many oils which is the anti-wear additive for flat tappet cams. M/C oils still have it.

Oils and additives have been developed Specifically for MotorCycles such as Anti-Wear additives for the transmission, Anti-Rust and Corrossion Inhibitors to protect during periods of Non-Use, and Specific Clutch Performance Additives.

REGARDLESS of Brand, I always recommend a MotorCycle Specific oil with a JASO Rating of MA, better yet, MA 2, but never MB..

Sportbike Magazine disagrees with that article and so do many people.

Oil, is the LifeBlood of your engine, why try to save a couple dollars ?

wow!!!! you swap out double ester 300v after every 1000 miles?!?!? you gotta spend a fortune on oil!!! that stuff is 16 bucks a qt.!

those are all just myths. i switched from suzuki 10-40 to amsoil 10-40 and believe it or not it made a huge difference. feels a lot smoother, shifting is smoother, and it made a difference in power delivery i never use to spin 1st but now i gotta watch my throttle

Ran Suzuki 1040 until 1500 miles then switched to Amsoil 1040 Full Syn. Motorcycle oil/filter. I change the engine oil at least twice a year. Its a track bike only. I run track 6-8 times a year. No racing................yet. I love the product and wouldn't use anything else at this point. If you have seen my trackbike I have Amsoil stickers all over it. I am a big fan!

whats up guys ... amsoil prefered cust.... i use amsoil 20-50 in my softtail and amsoil 10-40 in my gsxr... i have been a mechanic for 18 years and seen lots of differnt oil and nothings beeter then amsoil:thumbup

I use Repsol Fully Synthetic 10W-40 every 2500 to 4000 miles

I use Amsoil in my bike and car. I have no problems with it. I'm also a dealer.

synthetic rotella t

I use Rotella T synthetic and change it every 3k. K&N filter changed every other time.

Rotella T Synthetic... around 3-3.5K per change

Rotella T Synthetic... around 3-3.5K per change

0-100 miles ran stock oil.

@100 miles changed the filter and switched to Rotella Conventional

Ran that until 1500 miles and switched to Rotella Synthetic.


Will take a sample at 4500 (3000 miles on the oil) and send it for UOA, and see.

shell rotella t ..imho everyone else is wasting their monies on crap like amsoil:lol

Never hit that 4500 miles.

Actually, the riding up here was kinda rough after I did the switch.


I am going to refill her come spring and try again.

Castrol GTX 20-50 and Scotts reusable filter. 1/4mile only no street, change after every 20 passes.

Nothing better than $16 oil changes:cheers

You change your oil every 20 passes ???

Are you running some exotic motor that you are really worried about ??

Thats pretty extreme otherwise..... I think... compared to how hard the bikes get worked on a roadrace track for far longer

Amsoil 20-50, I change it every 3,000-3,500 miles

You change your oil every 20 passes ???

Are you running some exotic motor that you are really worried about ??

Thats pretty extreme otherwise..... I think... compared to how hard the bikes get worked on a roadrace track for far longer


Yeah every 20 passes or so, gives you a chance to check the filter for bearing shavings and clean out clutch fiber. If there is any bearing material it is alot cheaper to pull the motor out before they are totally gone and you kill rods and crank.

Its just a stock motor with a little nitrous, but alot cheaper for oil than crank or rods

Can I run extended oil changes with Amsoil? Or should I just change it at 3K

I use Lucas 10w40 full synthetic, as far as how often i dont go by millage if i cant see through the sight glass i change it.

OK, I get that. Since you are using the oil change to check for those things, it makes more sense!

Hey ANdrew ever get those test... I am speaking to Eric who lives here in M.A and he said that the Rotella T synthetic 5w40 is all he uses and he loves it. And price cant be beat I am pretty much sold, wally world is only 10 minutes way which is great, I am actualy sold by my car forums as well they swear by it for high horsepower Twin turbo VR-4's.....

I want to do some test as well..... but if you got some I may as well check them out and compare!

I live in a colder climate mind you bu for all my engines, car/truck/small engines/bikes, etc... I have always had a tendency to look for thinner oils in most everything. 5-30's usually Dino-oil in spring summer fall.

synthetic in late fall winter early spring as synthetic oil flows much better when coldstarting in the winter. When I can find a synth 0-40 or 0-30 I will us those (and hoard them :p ).

This way I get great protection yet don't spend a bucket on oil.

AMsoil makes a 0-40 motorcycle oil I'm fond of but its expensive of course.

I'm a anal sob when it comes to coldstarting, engine warm up and so forth so to assist this even further I use Lucas Oil Stabilizer in everything except motorcycles engines. Yes it helps a film of oil adhere to all metal parts which greatly reduces start up wear but its been shown in tests from ( http://www.bobistheoilguy.com/images/lucas/lucas.htm ) that it tends to froth up the oil creating bubbles and holding in heat when used in high reving applications (ie. motorcycles :dissapointed ).

Excellent though in things such as gas/electric golf cart engines lawn tractors and the such. Also it prolongs oil considerable (claims it doubles changer interval to 7k!) in car motors,yes to be precise you need a used oil sample and a lab but alot can be told my checking it yourself in color, smell and texture as I have.

Excellent product! used it for years now.

Amsoil in everything I own. Won't use anything else, and I don't think I can get a better price than I do now from a dealer near me.

Pennzoil 10w40

I ride it hard, every time i turn it on. And i'll go anywhere from 6-10k miles before changing it. Never had a problem.

And you just do this off of a whim without using oil analysis to verify ?

I have seen a test report showing a synthetic that had sheared a full viscosity grade at just over 3000 miles..

I sure wouldn't do it nor would I ever recommend that, much less tell people I did it.

Bob

amsoil, and every 4-5k

repsol synthetic 10w-40, change filter and oil at 3k miles

Valvoline DuraBlend 4T 10W-40 every 3000 Km

Mobil 1 4t. 2,500 - 3k miles. Used it for 10 years. Close to 100k miles on bikes combined. Never had any internal motor issues, therefore I don't see myself changing unless the stuff gets up to $20 a quart within the next few years.

Maxima full synthetic 10w-40...every 3,000 miles. Going to try Shell Rotella T6 full syn 5w-40 tomorrow.

Amsoil of course... durrrrrrrrr. 10-40 every 3k miles w/amsoil filter.

mobil 1 4t full sys. every 3kish with a k and n filter. I think the speciality brands like amsoil and a few other, raise prices for the same quality of oil just to compete with big companies.

AMSOIL's pricing is what it is as it is The Best oil you can buy and you are paying for the additives to make the oil capble of doing what it does. The Cost Per Mile and TCO are lower with AMSOIL than other oils.

AMSOIL does not have to worry about competing with other companies. AMSOIL dominates the market in Motorcycle oil and goes back and forth with Mobil 1 for the #1 position in overall sales. AMSOIL has over a 2.3 Million gallon Tank Farm, can load/unload 6 Rail Tankers and 4 Semi Tankers at one time inside a heated facility and has over a 400,000 sq foot Manufacturing/Warehousing facility in just one building.

The "Big Companies", as you put it, just keep trying to play catch-up and AMSOIL is ready with the next upgrade just as when the other Oil Manufacturers looked at the Original M/C oil tests, reformulated to get closer to AMSOIL as shown in the 2nd Test report so AMSOIL reformualted to make the M/C oils better.

Oil, is the Lifeblood of your engine. The Oil Filter, is the Kidney that keeps it clean.

Do you like the work Amsoil?

Not sure what you are asking...

I Love what I do

AMSOIL is an excellent product, no doubt The Best. AMSOIL Inc. is a great company to be associated with. If I find a better product and a better company, I will sell that. I really don't see that happening though. AMSOIL Pioneered an Industry in 1972 with The First API Rated Synthetic oil. I have been with them Since Feb of 1984.

Rotella T 6, I change the oil every 2,500-3,000

Mobil 1 Car 10-40, every 3-4k, K&N Filter. got over 35,000 miles on my 07 1000.

I use:

AMSOIL 20W-50 in my 2008 KTM SDR and as soon as I have around 2000 kilometers I'll be using AMSOIL 10W-40 in my new 2011 Suzuki GSX-R750. I normally change oil and filter about every 3K to 5K kilometers.

Also, I use AMSOIL 0W-30 Signature Series Oil in my two Honda cars. For the cars, I change oil twice a year, at the end of June and December.

This (IMHO) is the best oil on the plant!

Note: Since I currently live in Japan, I have the speedometers set to kilometers.
