Gasoline will keep a long time if you add Stabil product regularly.
May lose octane rating.
My fuel supplier has really warned me on diesel. Seems today's near
zero sulfur fuels like to grow a nasty slime. They have an additive
for this, but he has told me there have been several failures with
long term storage. So far, i've been able to back blend older stuff
(hi sulfur)and haven't had trouble.
FWIW, I topped up the tanks yesterday for $2.89/gal. I expect prices
to go to $#%^ next Wednesday.
I wouldn't go with 55 gallon drums unless you use a LOT of fuel.
I use common 5-6 gallon cans. With them you can rotate stock easily.
Transport is easier.
Storage is easier. Actual use is easier since you can just grab 5
gallons and toss it in a vehicle
then refill it as needed. I rotate my gas every 3 months or so.
As for treatment I use Stabil. You want to be careful with diesel. The
new stuff grows crud REALLY fast.
