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

[KenJax Tree]

i tried MC-1 i dont care for it, its burns a little dirty at 32:1

Because its way too thick to run the heavy, Bel-Ray recommends only 50:1

im burning some motul 800 at 32:1 in my weedeater and it doesn't mind the thick oils. i noticed the motul is cleaning the exhaust port quite well.
im just getting rid of the mix.

Anybody win yet?

Anybody win yet?

Not yet. I think it's narrowed down to 5 now.

Anybody win yet?

I'm not sure what quarter we're in....maybe 3rd. I think halftime were the mayhaw jelly and squirrel pics.

 

[KenJax Tree]

Its baseball season so we're in the 7th inning stretch.

When I run out of 800 off-road I might try some Yamalube.

R2?

Lucas....R2 doesn't come in gallons and i don't see how R2 is really any different than Lucas.

2R is not an injector oil for starters..

don't see anything specific about injector oil on 2S ...infact it says all purpose!

2S - says "all purpose 2 stroke oil"

https://www.yamahapartsandaccessori...ngine-oil?b=Engine+Oils&d=30|30&dealernumber=

This technologically advanced semi-synthetic base stock and additive 2-stroke engine oil provides all-season performance and greatly reduces visible smoke. Low deposits and reduced carbon and varnish deposit means longer engine life and greater performance over time. It provides exceptional lubrication in all temperatures, and a special additive maintains flow and prevents “gelling” in sub-zero conditions.

2R - says "competition 2 stroke oil"

https://www.yamahapartsandaccessori...ngine-oil?b=Engine+Oils&d=30|30&dealernumber=

A high-performance 2 stroke blend developed to stand up to high temperatures, rigorous demands and stress of competition engines. Special base stocks protect against wear and breakdown, low carbon deposits on pistons, rings and exhaust ports, reduces friction that allows for maximum horsepower.

Lucas might be slightly thinner but overall i highly doubt the 2R is any better. Lucas has worked for me so i see no reason to change.

 

[KenJax Tree]

Lucas is semi synthetic too.....also just as available and the same price and i can buy it in gallons

2s is an injector oil.

I'm not picky Keith[emoji2]

I highly doubt it's even close to the quality of 2R. Lucas might be close to citgo air cooled,which isn't a bad place to be.
