OK. I am confused. 50:1 means 50 parts gasoline to 1 part oil. Example: 50 liters of gas to 1 liter of oil.By my calculations 6 US gallons equals 22.7 liters. This means you should put about 0.45 of a liter of oil in to get a 50:1 mix.(Simply put - 100:2 or 50:1 or 25:0.5) Can someone tell me what I am missing?
Thanks

In the US we say you use 6 gallons of gas (48 pints of gas) with a
pint of oil so that is 48:1 (or 49:1 in the final volume) but in
either case, close enough for a mixture that was arbitrarily chosen in
the first place.

I like the little bottles that say. "mix the contents of this bottle with one gallon of gasoline for 40:1 ratio" Takes all the guess work out of figuring "parts"

Just be aware they are not full. Don't just fill them up and dump it
in. I think a full bottle is 32:1 and they short fill them for leaner
mixes.
I have some of those bottles with a little compartment at the top. You
squeeze the oil up into the top compartment and dump it in. It is the
right amount of oil for a gallon of gas.
One is 32:1, the other 50:1. That takes care of all of the yard tools
I have.
It has been a real long time since I used premix in an outboard, my
Merc 75 had injection but when I had the 1974 era 40 I used the pint
cans. I bought them by the case.

That could be Greg,but I haven't had any problems with using them over the years, but then again I'm not too worried about burning up cheap chainsaws and weed eaters. Besides that oil was made for air cooled too cycles...

However in my 2 cycle boat motors in the past, I did used the squeeze bottle with the top cup. I'd go 40:1 or just a bit thicker. Evinrude had that.. Not sure if they still do or not for the old water cooled 2 strokes...

I have a big syringe with a long tube on the end. It's marked with oil ratios on the side for one gallon of gas. Suck the oil out of a big container until it hits the desired ratio mark, squirt it into a gallon of gas, and you're done.

I did buy a six pack of Stihl oil when I bought my articulating head pruner.. In exchange they doubled the warranty.
.....

Sounds good to me if it works for you. I've seen those but never have used one...
