oil grades and styles questionair

[shammash55]

this is a lil poll i am curious about, i run rotella 15-40, looking for what everyone uses.

[bfe71730]

Castrol 20/50, use it in all my toys

Sham,
Read through the forums....

+1 on reading through the forums or even doing a search.

but.... don't use anything with a api rating higher than sj and you'll be fine. i run repsol 15-50 mineral oil in mine.

[cycleway4]

yes,...lots written about this.............but Honda GN4 10-40 anyway.

im using valvoline 20w50 motorcycle oil

Rotella here as well; especially for break in! High Zinc content does very well with hydraulic flat tappet designed camshaft and lifters. For me living in Florida I typicall run 15/50 or 15/40. May switch to full synthetic Wal-Mart brand..very cost effective.

What does this have to do with our China Bikes???

I believe it is Motul 10w40 mineral

[katoranger]

Using Rotella 15w40 for the breakin period then going to Amsoil or Mobil 1 synthetic.

Out of curiosity, would the Mobil 1 synthetic for cars have the same foaming problems as standard oil when used in a motorcycle? I wouldn't think so, but I'm no oil expert.

I've used Valvoline 10w-40 for motorcycles and Castrol 20w-50 for motorcycles ever since I found out about the foaming issue with conventional oil.

Just saying because there has been a huge probelm with hydraulic camshaft failures over the past 5 years in the auto industry and it has been linked to removal of zinc in most oils as it clogs catalytic converters. So higher zinc content and friction moving parts such as rings, rocker arms if you have a push rod style motor, even an OHC motor where there is not a roller type cam this high zinc can always help. If deisel motors with super high compression can run it Id bet its pretty good for a small 200cc air cooled single cylinder bike that works pretty hard. Just giving opinion..did I ruffle a feather cause I didnt mean to.

but how well do they perform with wet clutches? and what about clutch wear? i have no idea myself

I run Rotella in my YZ450F for the past 2 years and my wife's PitsterPro all with no problems and have not had to replace friction discs on either bike yet. Thats all my expereince.

the problem with running newer car oils is that they have a high moly content. our clutches are border line as it is. trust me guys run nothing higher than a API SJ rated oil, your clutch will thank you.

no need to run synthetic. our bikes have no oil filter so we should be changing the oil way before it ever has a chance to break down. i change mine every 500 miles. Repsol mineral based oil is $4.99 a liter at the local bike shop so $5 2 times a month is fine for me and my clutch slips allot less now that i stopped running car oil in my bike.
