What oil is best? and what ratio?

I need to pull it apart and dish the piston.

My Poulan 330 is one of the saws I have had issues with. No problems with 91 though. I don’t really trust my comp tester, but I think it was reading around 240psi.

Too much compression.

Too much compression.

I agree

Sir, I’m not smaht enough to have any idea why that changes anything. However I do believe you.

Lowers the compression by opening up the chamber

does more oil increase or lower EGT's.

I appreciate all the people in this thread commenting especially those with fuel distallation knowledge.

Some oils do indeed lower octane slightly while some actually raise it. If the oil uses a stoddard solvent or kerosene diluent octane will be degraded. However some oils use high octane diluents that actually raise octane. One example is Honda HP2 which uses cumene Cumene has an octane of 108.

Honda hp2 is some good stuff.

It will increase egt if you don't tune for it, but so will a 10 degree decrease in temp or a small increase in load.

Loved this oil with the exception that it didn't have dye.

Comparison to Amsoil Dom, the base oils, viscosity, mixability, bottom end lubing, muffler goo(lol) etc?
I've only heard good things about hp2.

I’d probably still be using it except I got a ton of yamalube products from a small shop that closed down years ago. So I’ve been using 2R since then. Think I only have a few more bottles left. Still have a bunch of quarts of 2S left. Not entirely sure what I’m going to do with that.

Liar!
I see 4-5 more jugs in that picture.

Explain Yourself mister!

The later stuff did have dye. I also have a quart of solvent red 26 i use for undyed oil. It is the red dye used for off road diesel.

Its good oil, but apparently so is dominator. Either is plenty good for a chainsaw and in reality over kill.

2S is injector oil. You will notice it's not as clean as 2R.
There are no warts on 2R. It's great oil that has a track record of great performance longer than most any oil.
