Is Higher Octane Fuel Better?

Generally, just buy the min. gas that your engine requires... altho always choose ones with no ethanol content... you don't want to buy **** you don't need.. but then.. i think even Shell (who used to sell no ethanol) fills their gas with ethanol now.

Unless you are buying from an airport, you have ethanol now. Even if you try to buy from an airport, 100LL plus cats is not a good thing.

Man that sucks. I remember reading on a RFD post last year that even the higher grades would now contain ethanol. I thought the Nitro+ grades were still good for winter storage (91/93/94) but I am getting conflicting info when researching online.

Sadly no. Apparently some marinas are still getting ethanol free fuel. Be careful riding your bike on the dock.

EDIT:
This says you can get E0 in Alderville or Huntsville. At this point, I wouldn't really trust any database or stickers. If I really wanted E0, I would test a tank myself.

Actually it's a resistance to PRE-ignition, ignition from compression. If you want to slow down the flame front, use a fuel with a higher specific gravity.

The way I understand it, that's the result of an overall higher resistance to ignition. Another is the ability to advance ignition timing without having the mixture ignite before full compression.
 
They only way to gain true HP is with the appropriate stickers..
 
Interestingly enough, I noticed at the Shell near my place that they have gotten rid of the mid-grade 89 octane fuel and have added 93 octane. So now 91 is their mid-grade. All containing ethanol I assume.
 
Read your owner's manual. Or listen to the technician that built your "off road/track only" engine.
 
I go with what my owner's manual says, unless it's an emergency, which hasn't happened yet.

I thought there was some new Federal legislation which came into effect saying that all consumer gasoline MUST have ethanol now.

Not entirely true. The late 90's Acura 1.8 was the same car as the Honda civic, but, in the Acura manual it called for premium gas, and in the civic manual it called for regular. The reason was purely marketing. Premium buyer gets a premium car and uses premium gas. Mazda used the same approach with their 626/mx6/millenia cars, until a memo came out telling them to have customers stop using premium because of carbon build-up on the rings.
