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).
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 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.
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!
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.
