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

[Mastermind]

Repped.

 

[redbull660]

Started breaking in my 2nd 661R - 2 tanks through it, both running belray H1R 45:1.

I know it's only two tanks and the pic isn't that good. (I tried taking about 15 pics and this is the best one I got). But the top of the piston has a light grey/brown tint to it, I can still see the engravings on the top of the piston clearly. No build up at all! My understanding is this is ideal?

Now Stihl ultra on the other hand would already have a black coating. I've broken in 4 660's a 661 and 461 in the last yr so with ultra, so im pretty confident in this statement.

spark plug..

Bwalker i need to know what makes u think a chainsaw engine is a low stress enviroment or whatever u wrote ?
Because they dont make the power of similar size motocross engines ?

I already ask that and got tore up by Walker and Brad!!! Lol!!

HP per cc is low as is load.

How the hell do you know this as fact??

First off. How the hell do they know it.
I know it to he false because I have seen some of the oils in question ran at higher rpms..

Why 404 chain?

 

[Roll Tide]

Are we still talking about these oils being run in chainsaws, or other totally unrelated 2 strokes?

What's up with all the oil around the spark plug hole?

 

[bwalker]

Cheaper

Never would have guessed that. Also never seen 404 around here used on a saw. All 3/8 .058

Are we still talking about oils made for two strokes totally unrelated to chainsaws?

I agree Mtronic and Auto Tune are a step in the right direction.

Total waste of time.

Not a waste of time. I run 40:1 high octane and it does leave a little carbon on the piston but I'd rather have that than the ethanol heating up my saw. With 40:1 I know I have oil on my bottom end not think I do with 50:1.
I've replaced scorn Pistons with them run on 50:1. I think this is all do to the constant changes in ethanol percentages in are gas today. I think this is a great test and thank u for doing it.
