Oil's question.....again?

[gusto]

I'm hoping some builders and folks who have done a lot of rebuilding can chime in on this. Went looking at two stroke oil for my new engine. Prices were $18 to $6 bucks a quart. Regular, semi, and full synthetic. Back in the day (20 years ago) I ran the cheap castrol stuff with no problems. Does the expensive synthetic really run that much better? Can you nice a difference in the life span of an engine with wear and tear?

Also why do some folks run synthetic for their clutch? I always heard not to run synthetic.

synthetic 2 stroke oil burns much cleaner. I run amsoil dominator 50to1. with no oil related failures.

 

I run 0-20 synthetic oil in the trans, thats what the builder who cut my duneable overide recomended.

As long as it's quality product and consistently mixed. IMO, the synthetics are providing better life. As for the synthetic in the clutch, again it's better life. It also helps manage the heat a little better which helps with fade on long rides. Last benefit, I noticed it seems to have a consistent more predictable feel when being slipped a lot intentionally.

For what its worth I run Bel Ray MC-1 50:1. And I run the Bel Ray gear saver in the trans. I believe most of the better gear oils are semi synthetic but not 100% synthetic as this can cause a typical clutch to slip. I'm not familiar with the locking clutch set ups. I was always told to run the standard non synthetic oils when you are breaking in an engine. I just ordered a case of 12 16ounce Bel Ray MC-1 for 115 bucks.
