What ever happened to Monel?

Maybe that fuel is not too bad, it is maybe 8 months old. I ran it in the car 50-50 ok.
I Pumped out 35 gallons of yellow looking but clear gas.

 

There are many sources for clear 5 gal GLASS jugs,,, hobby beer folks water purists..

Put in any old fuel in and let it sit for a day , you will easily observe which to salvage and which to discard.

 

What are you looking for at the end of that day ?

There will be a line across the fuel with water & gunk below and clean fuel above.

No visible crud ? pour it all back into the fuel tank.

 

Even with no line where the gas phase separated, fuel goes bad if exposed to oxygen in the air and metal in tanks. And filters cant filter out gums. I have run gas in cars that looked ok, but it caused intake valves to stick.

 

Fuel oxidizes, which reduces the octane. It depends on the type of fuel, how fast it happens. Oleofins combine with oxygen and create the "gum" that clogs fuel systems.
