How do I add gas and oil to a gas can half-filled with 50:1 mixture so
that it stays 50:1?

For example: I have a 10 gallon can on my boat filled a little more
than half way with of 50:1 mix. I can't tell exactly how much 50:1
mix is in the can. I am at a gas station and want to top off the can
and yet keep the mix at 50:1. How would you do this?

Here are some possibilities I can see:

1. Put in a known quantity of gas that stops short of filling up the
tank. Calculate how much oil is needed for that known quantity of
gas. Add the oil, shake the can. Accept how much empty space there
is at the top of the can.

2. Fill up a another can with maybe 6 gallons of gas and add the
correct amount of oil (5/8 of a cup,.. or 10 tablespoons maybe).
Shake up the can and pour it into the 10-gallon can.

Any ideas?

Thanks

If your can is a little over half full, put in four gallons of gas and add
10 oz of oil, plus a couple drops.

Siphon the gas into the near-empty tank of your car, then fill the car's
tank. (Per my mechanic, this is not a problem).

Start from scratch with the boat fuel mix.

Go to your nearest Vespa scooter dealer and buy the little mixing cup.
When you go to the gas station, note how many liters/gallons you pump into
the gas can. Fill the mixing cup to the corresponding mark with the proper
two stroke oil. Add the oil to the gas can, shake a bit, and away you go.

Go sit under a bridge and ask everyone who crosses three questions...

I'd just mix for 5 gallons. At 50:1, I dont think its gonna matter. If
in doubt, mix a little heavier. You wont hurt the motor.
You could dump 2 quarts on "justwaitafreakinminute" , then mix the
rest.

Direct from Harry Krause:
Been a long, long time since you posted anything useful or original
about boats. What sort of boat do you have, and where, generally, do
you
boat? Got anything on topic to add here?

This is what I use to figure out how many tsp.(teaspoons) of oil
to add to a pint of gas for a 50:1 fuel ratio for gas string trimmer.

1 pint to tsp. = 96 tsp.

Rounded off to 100 tsp.

A smig over 2 tsp./pint of gas works.

A pint almost fills the string trimmer and I don't need to mix any more
than I can use at a time.

If I need another half of a tank. A heaping tsp. of oil to a cup of gas
works.

Now you figure how many pints of gas you add to the tank then add two
heaping tsp./pint.

2cups = pint
2pints = quart
4 quarts = gallon

Do the math yourself from here.

I have a syringe that is used to measure medication in cc's and tsb. that
I use for the string trimmer.
