2 stroke oil

Divide cc by 16.4 (16.387) for ci

 

All this oil debate is interesting but IMO carb jetting and tuning is more important and chain being the most important link . Nothing adds up if the chain isnt on par like Mdavlee, Hedgegrow, Mopar, Squarefile and some other guys have figured out to a perfection

 

I thought that oils job was to lubricate.

 

Yes which reduces and manages temperature

 

You are lumping me in with some real slick chain dudes ............... I dont even deserve to be mentioned in the same breath as the others.
I got lucky with 1 chain in 1 or 2 races ...................... luck runs out sooner than we expect !!

 

Making fast chains is 30% skill, 50%, and 20% voodoo

 

It reduces friction thereby preventing more heat. But the overall fuel charge is what's cooling. At least that's the way I understood it.

 

Sounds right. The way I see it is heat is what causes the air took in to expand and force the piston downard. If oil reduces temperature wouldnt that mean it was impeding combustion to a point?

 

I wonder if the autotune huskies where they use so little fuel is the reason some of the oils cause them some running issues.

 

Mike this is just a guess and thoughts. If the autotune leans the saw out in search of max rpm and then u add more oil,(32:1), and try and force the xtra oil through the jetting set up for 50:1, wouldnt that make the saw even that much more lean?

 

I would bet if somebody wanted to run 32to1 in mtronic/autotune , if they redrill the main jet it would run much better?

 

How much different is the husky strato than the stihls?

Is it a jetting problem or an issue with the programing? Are the carbs the same except the solenoid?

 

I think the autotune only searches for rpm is my understanding

 

Are you saying the oil causes the heat from the fire to be less?

 

I think to a point yes but just a guess

 

There's not a great difference but the huskies seem to go longer on a tank. most of the carbs are zama.

 

Oil has more energy than gas per btu. It takes more heat to ignite it. Some of the oils don't burn as easily as the others and don't contribute to the boom.

 

That makes sense. Thats why Im thinking I will like the less viscous R2 . Im thinking it will combust more efficiently

 

Im thinking R2 , K2 at 32to1 will be a much better choice in mtronics/autotune

 

I wonder about R50 and 800 off road .................... those are 2 thick oils in the container and everything runs great without any tuning issues, unlike H1R
