What oil is best? and what ratio?

That saw is a screamer! Really hustling there.

I really like it for limbing and small wood. I wouldnt mind havin the new red Makita 4300 either

I like the 421/4300 I don't know if it would get much use with a hot 346 around. then again it may just make it easier to keep the 346 on the shelf all polished up. lol

efco mix is the same color as red armor.

Lead helps with valve seat wear, but won't do a thing for a two stroke.
I would worry much more about using non ethanol fuel than the octane number. The compression ratios of chainsaws are so low that even modded ones can run on 87.

Lead doing nothing for two strokes is your opinion, not mine and many will disagree with you based on experience. Lead helps all engines reduce ring and piston friction, period.

The people that think that do not under stand how lead actually functions in a four cycle in regards to valve seat wear.
Lead does not reduce ring and piston friction at all.

Lead does lube those old pre 72' cast iron heads with non hardened seats. It sticks to the hot exhaust valve face. After 73' in US cars lead does nothing for the head seats because they are hardened. Lead will *f-word up a lot of emissions stuff. The lead does more for valve guides than anything else IMO.

Only when cutting the cheese.

You need oil to help with that?

 

[Fifelaker]

Yes, pull my finger

 

[stihl023/5]

Yes, pull my finger

No you are lubed.

Lead doesn't function as a lubricant at all as it pertains to valve seats. What it does do is form lead oxide components that stick to the valve and valve seat. This buildup acts as a cushion that prevents the valve from contacting the seat.
These lead compounds are actually salts and serve no benificial function in modern motors. The opposite is actually true as they can be corrosive.

Oh ya! He grab his tail and hollered , "RED ARMOR!!"

Lead was good for its ability to run higher compression ratios. Tetraethyl leaded fuel won't give a power increase by itself but in times past allowed higher compression thus greater power. I don't miss leaded regular pump gas one bit, but I would not want to use it in catalyst exhaust systems that we see now days, they would not like at all. The oil thread has morphed again into other subjects which is OK.

Back on track,maybe. Am I the only one that runs dominator?

 

[RI Chevy]

I have on read posts about Saber.

Possiblu. No rust protection if I remember right.

I will check with dealer on that.
I will say increased performance in the machines I run it in.

I run 91rec fuel w/conventional oil @ 40-1 in my weed eater, leaf blower etc. Ran out of gas last wkend while blowing leaves. During second tank of saw gas run thru the blower, darn thing woke up and started running really great! Always ran it lil fat, actually smoothed out.
I'm sure it's the oil, and yes I run saw gas @ 32-1, 100ll.

 

[KenJax Tree]

There is no rust protection in Dominator. It says right on the bottle not to use in boats that aren't frequently torn down. I've never seen it myself but guys have had cranks rusted using it in dirt bikes.

If you're gonna use Amsoil IMO use Saber. Blended for OPE and has a stabilizer.

 

[danimal]

Hmm. I do use amzoil quick shot fuel stabilizer in my 5 gal can of race fuel. Mix gal at time with oil for saw mix. I thought stabilizer took care of the corrosion problem.. Maybe I is wrong
