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.

Even Walmart carrys more than one variety of fuel mixing aid.




Bass Pro is a bit of a drive for a small item. Wal-Mart is not a store
I'd patronize. Lawnmower and lawn tractor shops carry the oil/gas mix cups.

My string trimmer and chainsaw use the same oil/gas mixtu one small
plastic jug of two cycle oil to a gallon of gas. So, I use up the
mixture in the gallon jug and then pour in the oil and take the gas jug
out for a refill. No mixing, no muss, no fuss.

My favorite is a Sea Sense Oil Mixing Bottle. The various measuring
scales on the bottle are idiot proof and quick to use for any ratio
and any amount of fuel. Plus it has a screw on lid so it stays clean
inside and doesn't make a mess while it's in storage.
You can find them anywhere. I saw them last night at my local Walmart
for $2.17, and they're made in the USA. They don't show up in a
Walmart "search" but here's a link to a picture and description.

same one that Bass Pro sells. I use them for everything that runs on 2
cycle at my house, too.

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.
