2 cycle mix question

[bchannell]

If you use gas stabilizer in your gas before you mix you're 2 cycle gas should I avoid using 2 cycle oil that also has stabilizer in it?
I always stabilize my gas in my big can, then have to go fill a smaller can for my saw, blower and trimmer, so as to not double up on stabilizer.

doesn't matter. double up on the stabilizer. It won't hurt the gas, nor your engine

Are you using ethanol free fuel??

Go with premix. How many QTs do you use a year? Its not the price per gallon but cost per year. So if it costs me 2 QTs/yr that's under $10 and I will have a good chance of no gas/carb problems ever.

I have a 5 gallon gas can that I mix about 12 OZ of MMO and 8 OZ 2 cycle oil and then fill it up with premium fuel (so as the octane rating drops slowly it will be a long time before performance is effected).

I go 2 years on that 5 gallons and haven't had any issues. My 15 year old Craftsman B&S 5.5 hp is still on the same plug for the last 8 years since I have owned it. No smoke and starts on the 1st or 2nd pull.

That combo has worked will for me.

Safest bet would be ethanol free racing fuel then mix it w/ your 2 cycle oil mix (synthetic type is preferred).

I mix 5 gallon worth once every 2 yrs for chainsaw, trimmer, blower etc, and I don't even bother empty out the fuel over winter, since there's no ethanol to degrade the fuel.

Never had any fuel related problem in my 2 cycle machinery.

I do the same, but with regular 10% ethanol fuel. Still no issues.

This is the correct answer.

Why is synthetic 2 stroke oil preferred? Why exactly,except in the most demanding applications would it even matter.
My mom has a 5 gallon gas can. It takes her 2 years to use it up. It doesn't even have an air tight lid although I do put a plastic bag in between the nozzle when I fill it for her.
In those 2 years it takes her to use it all it gets no stabilizer nor any additives whatsoever and her 20 year old mower runs just fine whether or not its fresh or the last of the jug
Op. it doesn't matter unless you are grossly misusing the stabilizer,so doubling up isn't going to harm anything.

The same reason why I use synthetic motor oil over dino.

I run ethanol free race fuel mixed w/ Stihl Ultra Synthetic 2 cycle oil w/ 40:1 ratio in my race saw (Modified & ported MS-660R). Conventional oil won't provide the protection I need at 14,000 rpm.

Since I have to mix 5 gallon at a time, I use it in all my 2 cycle equipments: Stihl trimmer, weed whacker, blower. Too bad Stihl doesn't make a 2 cycle lawn mower ! I'd love to modify one.

Synthetic 2-cycle oil tends to create fewer deposits in the engine and muffler, requiring less frequent deposit removal maintenance. A cleaner-burning oil usually results in a cleaner engine.
