I have too many small 2-cycle engines and keeping track of the oil/fuel
mixture ratios in all the different gas tanks is getting to be a chore. I
now have ratios of 25:1, 32:1, 40:1 and 50:1, with factory recommendation of
regular gas for one engine and premium gas for another, so putting the
wrong fuel into the wrong engine is very likely giving enough time. Someone
posted sometime ago that he only use one ratio with one particular type of
oil and never had problems over a long period of time with various 2-cycle
engine. Anyone know what this ratio and type of oil are or would like to
comment? Thanks for reading.

If it were me, I'd keep a can of 32:1 for the 25, 32, and 40, then
keep a separate can for the 50:1. I used to keep 32:1 around for
everything until I paid $300 for a new Stihl trimmer. It has it's own
can using the 1 bottle to 1 gallon Stihl brand oil.

I've never seen any power equipment with a high enough compression
ratio to need high test fuel. It's more expensive, but you could just
run high test in everything (high test burns slower than low grade,
NOT hotter!). Or go with low grade in everything and keep an ear out
for pinging. Or use midgrade in everything.

If you don't already own a Ratio Rite, go to your local motorcycle
dealer and get one. It's a couple of bucks and takes all the
guesswork out of mixing 2-stroke fuel.
