about fuel for my '69 Variant, MT, FI 1600. Use 91 octane.
Is there any fuel out there that's greater than 91?
Any reason to use a higher octane than 91?
Gary, you find 92 and even 93 octane in different stations and different
states. I've just personally found running the better fuel keeps the engine,
and the heads in particular a little cooler. In the US, 93 is about as high
as you'll get, unless you get it at the race track. It really depends on
what you're wanting to do with the car-engine combo as to whether or not you
want really high octane. Some like to run a lot of timing to help with a
low end spot, others like to run high compression. These are where you would
need better fuel than 93 octane gas. Some like it because of consistency,
as it's tested more often to ensure it's what it says on the pump.
