OPEN UP YOUR MANUAL AND READ WHAT IT HAS TO SAY......The best advice you will get is from the people that built the thing in the first place... Let's see, a bunch of people that you don't know or the actual engineers that designed, built and tested the motor.....


Don't mean to be a dick, but this has been beat into the ground and your are going to hear fifty different opinions in a matter of an hour....

When you buy the filter, ask the shop guys what oil to use(if you're not shopping on line). Make sure it's designed for 4-stroke motorcycles(shared engine and gearbox oil). Semi-synthetic is good, full synthetic is better.

Mobil 1 Racing 4T is an excellent choice, and no, it's 10w-40. I prefer Amsoil MCF 10w-40 Synthetic Motorcycle Oil.

Crack your manual open and read the bottm of page 2-1, and also page 3-14. If you don't have one, get one:

That , sadly, is usually an excellent way to get stuck with the oil that has the highest profit margin for the shop, or the biggest kick back to the salesman, but not necessarily the best for your engine. Be sure the guy at the counter has your interests in mind.

If you're not sure that what you're getting is one of the best choices, compensate by changing it more often.

Yeah, hopefully the guys at the shop are cool, but I said that because the shop he gets his filter from may not have all the oils suggested in this thread. Maybe it's different over there, but dealers over here only usually carry a few different brands.

ya..i opened the manuel and read what it had to say..and i didn't know wether or not to use the 20w-40 or the 20w-50 because it recomended both types..i don't need brand types either because thats obvious to go with specific type oil..so thanks .

Well I hate to say it, but I think his point is to read your manual (follow it's recommendation for specific oil specs) or do a search on oil topics...yes he came across a little too strong, but to his point and mine...this subject has been beat to death for years. In fact oil threads probably make up 50% or more of all threads in the search area...Grey and Ben are being nice to offer info on this subject.....:naughty:

i live in ft lauderdale too. i sold my '03 450f recently. i used to just run regular sae hd 30 in it. it ran like a champ. however, i changed my oil every weekend or two.

i also upgraded to a stainless steel scotts filter to keep the engine internals nice and clean.

the main thing you will notice is the wide smile factor as you wheelie in any gear at any speed !!!
the main problem i had going to the 4 strokes is learning to grab a half a handful of throttle at times !!!

Maybe the subject has been beat to death, but it's going to be harder to prove than some of you think. Before some of you start in on the new guys for asking this question, see if you can do a search for the subject yourself, and see what comes up. If you actually got the results you thought you should have, what search parameters did you use?

It's a reasonable concern, after all, and it's made all the more confusing by all the choices there are, each claiming to be the best, and by the fact that it's a far more complex subject than the TV ads would lead you to think. On top of that, there's a tremendous amount of misinformation, mythology, and just plain BS surrounding engine oils for motorcycles, so you can hardly blame someone for feeling a little uncertain.

What most people dislike about oil threads is that they have a tendency to turn into pissing matches or slap fests. The people who complain the loudest are sometimes the people who start the slapping. If you don't want to respond, just ignore the post. Otherwise, contribute something, even if it's just a link to your favorite oil thread. But how about let's take the example offered here, and, well....don't be a dick.

:cheers:

I agree totally with Gray! From time to time there are new products and information on specific subjects such as oil which are discussed where we already thought we knew everything about that subject. Each time for instance the oil question is brought up someone reviews what others have to say and may determine from this thread and past threads that their best choice is xbrand as opposed to other brands which is what I think this site is all about. It's definitely true that this has been discussed many times just recently, yet it's not the exact discussion each time. Oh, by the way; Rotella synthetic which I determined was personally my best choice thanks to all these repetitive discussions.

No matter which oil you decide to use...change it often! It is used for much more than an engine oil, it also lubes the transmission (which chews the oil up in a hurry) and gets contaminated quickly by the clutch.
