Two Ccyle Gas Mixtures: Meaningful Differences Between 40 and 50 to 1 ?
 

Hello:

Have a collection now of 2-Cycle garden stuff like weed wackers, leaf
blowers, etc.

Some are older, some are new.

There is a divergence of requirements on the oil-gas mix for them.
Some say 40 to 1, some are 50 to 1.

Realize the best is to go by the manuals, of course, but it's a real pain
keeping different gas mixtures.

Any "real" and meaningful differences if I use just one ratio mix in all ?

If so, which would be better ?

Thanks,
B.

I'd shoot for 40:1 with a quality brand of oil (not the cheapest you can
find) and be done with it. Worst case should be perhaps a tiny bit more
smoke from some of the engines, but it shouldn't hurt anything unless
you're in CA perhaps and have the CARB Nazis after you.

32-1 is great for long life but what your unit recomends is how it is
tuned to run, often a richer mix cant be made to start well as many
units have the adjusting screws locked. The Epa wants less oil, less
polution, but you sacrifice engine life. There was a point Evenrude went
to lean to apease the EPA and engines started seizing, their 2-3000$
motors. Another better alternative is synthetic 2 stroke oil. Yamaha
should have one as does Mobil make a 2 stroke synthetic mix. I just use
32-1 and synthetic when I find it, my Echos start hard but run well.
Synthetics by manufacturer admissions allow a leaner mix.

Your trimmer has a catalytic converter? Does it have a check engine
light as well? Need to take it in for Echeck yearly? (shakes head)

The air/fuel mixture is adjusted to work with the oil mixture. Some
people think they're doing an engine a favor by using more oil, but
what that does is reduce the amount of fuel causing a lean mixture and
too much heat.

Most of my 2-stroke motorcycles have always taken a 32:1 mix, thus I
always have a can of it around. The weed wacker got whatever was in
that can and was always happy with it.

Now I have a new Stihl trimmer. It cost enough that I'm not taking any
chances. It has it's own gas can mixed with the pre-measured oil
bottles supplied by the dealer. And, it has a catalytic converter
which is a whole new issue.

Anyways, if you're dealing with a collection of equipment that ranges
from 40:1 to 50:1, just average it out and mix one can for everything.
Be sure the oil is rated to that ratio. If you don't already own a
Ratio-Rite then go to a motorcycle shop and get one.

Too rich of a mixture will also plug the fire screen in the muffler.
In addition make sure you empty the gas can completely before refilling and
creating a new mix. If you leave mix in the gas can and then put in a full
bottle of oil the mix will become too rich.

I saw an interesting measuring cup set up to measure 10 through 70 to
1. It was called, " ration rite". Wierd place to find it was in a
Harley Dealer ship, Chicago Harley in Glenview, Il.
