Mixed up gasoline cans

[downslope]

I have two 5 gallon plastic gasoline containers. One has about 4 gallons of ethanol free 91 octane in it, the other has 4 gallons regular 87 pump gas with ethanol 10-15%. Is there some way to figure out which is which since they got mixed up? I need to use the ethanol-free in the riding mower and since it cost like $4.40 a gallon I'd like to use it for that and not repurchase if possible.

The corn gas won't bother the mower. That's all I used for years without any trouble.

How much gas do you burn a month? I might consider combining them and just run it. Add SeaFoam or Marvel Mystery Oil.

I wrapped a piece of green marking take around the handle of the cans I use for real gas. Something to consider for future.

Perhaps a test tube color test. Draw a sample of known corn gas from a vehicle for control.

Does it really matter? If the non-ethanol is $4.40/gallon and the ethanol stuff is what? $3.30 a gallon? If you replace it, it's costing you less than $5.

(4 gallons * price difference)

Put a bit of water in a small container, preferably a tall narrow one similar to a test tube. Mark the height of the water on the tube, now pour in 5-10x as much gas, shake and let it settle. If the separation line between fuel and water is higher after letting it sit for a few minutes, it's the ethanol gas. Reason being ethanol will mix with water and separate out..........Mike

Dump both in the car and move on.

Mix them together and use them up, as has been said a bit of stabil or my favorite additive a bit of 50-1 two stroke oil.

Seems kinda like trying to pick the fly chit out of the pepper!
