For almost half the price, i use Mobil 1 4T fully synthetic bike oil, and it is excellent. The inside of my engine is immaculate - super clean. Mobil 1 car oil has a fantastic reputation, and that is why i use Mobil. Have a look at their web site, and Motuls page.
If i had the money, i would use Motul fully synthetic (not sure if it is 5100. think that is semi-synthetic), but here it is around $80 for 4 litres, and Mobil 1 4T is $45 for 4 litres. (AUS dollars)
But either way, you should really use a true fully synthetic oil if you want the 'best'. The difference between a mineral and quality synthetic is a quantum leap. The best analogy is 'like comparing carburettors to EFI'.
Do a search. i have discussed the difference in viscosity ratings somewhere here before.

There's no doubt that the oil you're using is a great product but there's a bunch of guys around in the crotch rocket and YZF circles that have been using car oils for years. A lot of folks use Mobil 1 15w-50 which is a car oil. The "car oil" I use is rated by Caterpiller, Allision, and Cummings for transmissions.
The bottom line is use whatever you feel comfortable with. However, there's just too many people around that have been using non-motorcycle oil for years with no problems to say they're bad so therefore you need to go out and buy $7 a quart motorcycle oil. Again, the motorcycle oils are good oils, but if you take the time to get the raw data from the oil companies you'll be shocked at where some of the expensive motorcycle oils stack up against a common car product.

I am not saying that expensive "motorcycle oil" is a waste of cash, but if you used say, Castrol 10w30 or even 20w50 in your stroker and change it like you are supposed to then you would NOT have any problems, clutch, engine, gears, or otherwise.
Now don't go and use some crap in the plain yellow bottle that says "Texas Star Oil" or anything like that, just use a name brand, certified engine oil and change it according to your usage schedule, and you will be fine for years....!

Thanks for your e-mail!
Your observation is correct...here is a short explanation of the situation.
After the API SG period, the API made some changes to the limits on
additives that we, as a motorcycle oil manufacturer did not agree with, for
implementation during the SH period. These restrictions became more intense,
and fuel efficiency tests became more difficult to pass for SJ approval and
manufacturers were forced to use lighter oils and friction modifiers to meet
the new SJ fuel efficiency tests.
We decided to halt placing the API symbol on our products since this would
mean we would have to limit our formulations to meet these new automotive
derived needs. Further, we decided to continue to produce the SF/SG
formulation that we always made since we know that it is superior for
motorcycles.(and this has been confirmed by almost all motorcycle
manufacturers worldwide by their broad recommendation to use SF/SG oils in
For a while, the API refused to allow even this SF/SG designation to be
placed on a label! Their reasoning was that it was not their current rating.
They then realized the reason we were doing it and then allowed SF/SG to be
put on the label without their "donut" logo since our oil is primarily
recommended for use in motorcycles.
Now, if your engine manufacturer requires API SH, we meet and pass all those
tests too. Except,we do have anti-wear additives in our oil that are over
the limit for the SH requirements but we are very confident that
recommending our oils for you with these extra additives is the right
recommendation for a motorcycle application.
Our full synthetic race oils do not exceed the upper limit levels of these
SH anti-wear additive restrictions and therefore have the API SH on the

Subject: bottle labels accurate?
I have purchased some of your "Golden Spectro 4" synthetic blend oil. The
label on the bottle has it marked as sf/sg but your web site says that it is
good for sh applications. Is the label inaccurate or is the error on your

I have used Yamalube 20W-40 since I first started with the YZ-F's at the end of 97. I have never had any oil related problems. I must say that I am pretty anal about oil and filter changes.
I have been looking real hard at the VR1 oils. The only thing that keeps me from trying it out is that with my discount the Yamalube is cheaper. I have never seen the VR1 oils on sale. YZ454, Where do you buy yours.....and do you get it for cheaper than shelf price?? Can it even be found cheaper than an auto parts store??
