661 Oil Test 32:1 vs 40:1 vs 50:1 ?

2R, K2, and motul 800 are popular. I guess we could add a poll now.

I am not following you how you make the jump from viscosity to oil ratio..

Yamalube 2R (8.5 viscosity) and 800 off-road is (15.5 viscosity at 100C). Going from 8.5 to 15.5 is an 82% increase. Translate the percent difference to whatever ratio you want for a comparison. Pretty easy.

I think your logic that a increase in viscosity allows you to use less oil flawed, but your welcome to try it on your equipement.

Is $10.99 a quart for Yamalube expensive?

I can get a liter of Super M for the same price as a quart of Yamalube. So i'll probably stick with Super M or Lucas for blends and K2 for full synthetic.

I seem to like using semi-synthetic oil better than full synthetic.....so how bout Yamalube 2S $30.99 a gallon.

 

[KG441c]

What is 2s?

 

[KG441c]

Injector oil

Anybody try this?

 

[KenJax Tree]

Injector oil

Yeah i see that now, the Yamaha site didn't say that

 

[brockhaskins]

They typically are pretty thin.

Thin = bad ? Or too thin = bad?

I would not use 2S in a saw.

Its about balance.. Too thick and it combusts like crap. Too thin and it doesn't lubricate as well.

make sense. I'm sure the application matters quite a bit as well.
