What octane gas would you use?
Hey guys, new to the forum. Just got my 2004 commemorative convertible and was wondering which gas you guys would use? 93 octane with 10% ethanol or 91 octane with no ethanol from shell. Thanks ahead of time!

E10 sucks, E15 is worse. do not use it and call your Congressman. They are about to make our cars undriveable. I will not put crap gas in my car. 91 min all real gas in my Vette
E85 takes some conversion.

Wish I could get 91/0 here in Florida. I use V-Power 93/10.

jet fuel is probably the worst possible thing you could put in a C5. Its not a jet. JetA and JetA-1 are a kerosene based fuel used in gas turbine jet engines. very similar to diesel.
Now Avgas is another animal used in piston driven aircraft. not to be confused with JetA or JetA-1
Avgas can be as low as 100 octane and as high as 130. Using more octane than needed to control detonation will seriously inhibit performance.

Around here all the premium grades have 10% ethanol in them - car runs fine with it in the tank.

Here in WA we have 92 octane premium but it usually contains "up to 10% ethanol) according to the label. My supercharged C5 runs fine on that.
I just got back from a weekend in British Columbia and they have a super premium 94 octane with no ethanol
Only problem is that it's $1.50 per liter
