What oil is best? and what ratio?

[Keith Gandy]

Omg you never stop lol
No offence to Julian but he's never worn out a pro saw.
Yeah probably the last guy's I'd take advice from in regards to a good performing oil in chainsaws over it's life are guy's that play with saws here and there.
You know I'd like a little more evidence that an oil is the greatest than I've run a couple gallons of gas and am here to tell you this is the greatest performing 2T oil in chainsaws bar none! Lol
Common put up the pics of saws run on the same oil for a couple thousand hrs I might believe the hype then

I'm going to keep using Dominator. Period. I don't care what anyone else uses, and I don't care why they use it.

Just ordered me a gallon

That's a good attitude to have on oil for sure

I didn't miss Julian's testing. He figured out that H1R was hurting performance to the tune of about 30%. Thick as molasses....

I mentioned that to him on AS before he started doing all his testing. At that time H1R was the in stuff, which ai thought funny given its complete crap.
Blaming it on viscosity causing increased friction isn't the whole truth either. You also have to consider nits effects on combustion.

There was a stationary engine test years ago using RC plane two stroke engines that made H1R famous among those guys. That's where the hype started if my memory is to be trusted.

Thanks. They can't figure out what's causing presyncope spells. They did figure out how to charge me 2200$ out of pocket for 4 cardio test yesterday!

I went thru something similar several years ago. They ran tests, hooked me up to monitors and ran me on a treadmill. Turned out to be a tick borne illness like lymes disease.

Can't disagree with that Ben.

Red Makita 50:1 , mixed at 40:1 sometimes up to 32:1 for long bar & ported saws.

This is my secondary Dolmar PS-7900, she "oil hydro locked" on me today, nearly broke my fingers.
Anyone ever had their saw lock up from excessive oil?
First time for me, had to intentionally flood the engine to dilute and wash out the oil.
Pictures were taken prior to flooding the engine, pulled the muffler fearing she may have seized.

It’s not normally the oil that does it. The 7900s are known to seep gas through the needle and seat and will flood the bottom end.

For what it’s worth, Eggshooter ran vegetable oil at 50:1 and it left a sheen on the piston.
