Yes, a follow up to my leaf blower question. I'd rather move on and
learn from this. I *do* know that 2-cycles require a proper mix of oil
in the fuel, and I *did* read the manual, but I managed to screw it up
for a variety of reasons.

Given that I'm not the only person with a busy life and crazy-ass
distractions, how do YOU try to make sure that you get the right oil
mixture in your yard tools?

US measurements are just the first of many ridiculous parts of the
equation here (sorry, traditionalists). You get a 32-ounce gallon (or
64-ounce two-gallon) container and

This is part of your trouble: 32 ounces is a quart, not a gallon; 64 ounces is
a half gallon, not two. One gallon is 128 ounces.

some other container for the oil and
directions to put (say) 6.4oz (out of 8oz in the container!) in the gas
-- but who has a fluid measure with tenths marks?

The easiest way to do this is to buy a one-gallon gas can for each different
mixture that you need, and buy 2-cycle oil in the appropriate size containers
for mixing one gallon of each mixture.

For example, some of my 2-cycle tools need 32:1, and some need 40:1. So I have
two one-gallon gas cans, labelled 32 and 40.

I buy 2-cycle oil in 3.2-ounce containers for mixing 40:1, and in 4-ounce
containers for mixing 32:1. With the gas can empty, pour the oil in, and add
gas until it's full -- and the mixture is right. No measuring, no calculating.

Whatever mixture you need, just look for 2-cycle oil that's labelled for
mixing that mixture. Or calculate it: for an x:1 mixture, divide 128 by x, and
that's the amount of oil (in ounces) to use to make one gallon of x:1 mix.
Example: for 40:1, divide 128 by 40 and get 3.2.
