i got a barrel of 110 in my garage that was purchased in late october....how long can it sit before it starts to go bad?
Brad, I grew up in oil country, and did service work at both Pennzoil and Quaker States national HQ when they were both in Oil City, Pennsylvania (They've both since left to Texas, but back then, they were literally less than a block from each other).Learned a lot from those guys. Both main refineries were there in Reno, Pa and Emlenton, PA.
Here's the deal on octane, as I understand it from the chemical engineers at both companies. The higher the octane, the LESS pure the fuel is, and hence more resistant to detonation, because of the waxes and other stuff in there. The reason high octane (or premium) fuel is more expensive is because the oil companies get less by product per barrel they can also sell, like the parafine wax, etc. HIgh octane fuels have long had the stigma of being "More purified" or "hopped up", and that is simply not the case. Your regular, or 86-88 octane fuel is actually far more purified than the premium 91 stuff.
So, IMHO, to spend $5 a gallon or (gasp) $7 a gallon for the stuff is rediculous. Why is Diesel (FAR less purified than 108 octane racing gas) more expensive than premium at the gas station? 100 or more octane gasoline should REALISTICALLY cost somewhere between premium pump gas and pump diesel, as that is truly all it really is. Nascar and NHRA must be outta their minds to be supporting this.
As far as how long you can keep it, indefinately, if fully sealed in the drum, just shake the shit out of it before you use it if it sits for a long time. (How long do they store it in the "reserves"

What's stored in the national reserves is purified fuel, not crude, as most think.
And you guys now know where the Billion dollar oil conpany executive bonus money comes from.

Sorry to thread jack you on your fuel sale, this has nothing at all to do with what your costs are, really.
