When in doubt, throw it out Is it a teflon lined drum with the lids teflon coated? If not throw it out, if yes condensation even can occur with changing tempertaures in teflon lined drums

Geeez, put it in your daily driver, or your lawnmower. Never heard of anyone throwing fuel out, especially at the price it is today.

VP on it's worst day is still 10 times better than the crap we get at the pumps.

Back in 1988 I was using a race fuel made in SO CA, Daeco, in my415 HP 1963 max wedge stocker. I bought a 55 gallon drum in the spring and raced the car at all five division 7 races as well as brackets and time trials before going to each of the division races. I ran the drum dry during the World finals and had to buy VP at the races, the car picked up every time I put more VP in the car, we where running class eleminations so every hundredths helped. I called VP the next week to see where I could buy there product in SO CA at that time, the rep I talked to said that I should use the complete 55 gallon drum up within three days of opening it I ask why and he siad that the upper aeromatics would evaporate off if I didn't and the octane rating would would go down Maybe he wanted to sell more VP, maybe he was being honest Hence my saying, when in doubt throw it out(use it up in something you can't hurt with bad gasoline) DO NOT learn the hard way by burning up your motor I've hurt parts by using fuel that was not good, stored in a plastic fuel jug

He was giving you a song and dance if you were storing
it in a steel drum(where will it evaporate to) plastic
without a permeation barrier can loose the high ends)

I knew alot of snowmobile guys who used this approach.

I did this with a 275 gal overhead gravity discharge tank and methanol back around the late 80s. Used nitrogren to keep the air out.
Can be very dangerous as drums/tanks can only handle maybe 15 psi? (I would never go above 5 psi)and the larger tank the less pressure it can hold. And it's hard to get a safety valve set for 3-5 psi.

So in the long run it was not worth it, more hassel than the reward. Small leaks can eat your whole tank of gas quickly for one thing, the more empty the tank get's the more gas it takes.


This idea is along the same lines, I been using this for over 20 years to empty 55 gal drums. Discharge pipe get's screwed into the 2" bung and the pressure fitting goes in the 3/4" opening. Open 1/4 turn ball valve on the discharge side and crack open the valve with reg air pressure from your compressor into the drum and the fluid will come out right into your fuel jug or whatever with the drum sitting upright.

I open a 55 gal drum and fill 11 fuel jugs with methanol and hopefully only come home with 2-3 jugs worth. Can fill those 11 jugs quickly and safely if you know what youre doing, could never fill that many jugs every week with gravity or a sipon pump, it would take too long.
