VP or other race fuels

[pavulon]

So, my fun car needs 93 octane to run right. I can only get 91. It's about 50 miles to a very out of the way source for 100 octane (VP fuels C10) in 5 gallon cans at $11 per gallon. Wondering about options for this issue. Not very excited about having 50 gallons of fuel sitting in a drum in my garage. Perhaps several 5 gallon cans is the best option. Thoughts?

Can you buy avgas at a local FBO? That should cost $5-$6/gal.

Gas has a shelf life. Unless you are going to use it quickly you don't want 50 gallons aging.

Would consider this but the car has oxygen sensors.

VP C10 /C12 are very stable and store quite well. There are other "rocket fuel" mixes that do store well at all. VP offers 15 gallon drums too. Contact your local crack/VP dealer.

A less pricey way might be to buy a regular leaded 110 race gas like Sunoco purple and blend it with pump to get the properties you want. My local fuel guy has 110 for about $8.00 gal. for the dirt track guys.

I ran plenty of avgas through the 911. O2 sensors, but no cat.
Best thing to have in the tank when autocross season is over, and the car will sit for the winter.
Avgas stays stable almost indefinitely.

Eventually the O2 sensors will lave lead deposits, but all avgas now is 100LL, meaning "low lead".
The car will run happily for a long time with avgas.

A local race fuel dealer used to sell all me 5 gallon cans of something that I could blend with 91 octane gas to raise the octane level. It might’ve been MTBE, I don’t recall. It wasn’t the useless octane booster that you buy in the parts stores. You might talk to race fuel distributors in your area to see if they have something similar.

Where are you located? You don't say.

If at altitude, (like Denver) 91 O = 93 O at sea level.

or run octane boosters on the regular fuel?

Octanium. Have a buddy in the industry who swears pump gas octane is all over the map. He’s seen large swings up and down and swears it’s a crap shoot which what winds up in your tank.

E85 an option ? I ran it in my Corvette for 3 years, it was great. High octane and it burns very clean.

Your car (whatever it is - you didn't tell us) should run no differently whether it has 91 or 93 octane in the tank. That is simply not a big enough difference to make a difference. That, and you did not tell us what is meant by "run right". What changes? Or what is it that you think changes?
