none, they can all run on regular just fine. premium is not require, it's your preference. unless it's a higher end sports car like and Acura NSX. or it's a heavily modify engine for performance.

all H series engines are high compression and therefore require premium fuel. It looks like the F series engines do not. DO NOT PUT REGULAR IN AN H SERIES ENGINE. no matter what all the idiots on yahoo answers say. too low an octane rating in a high compression engine can cause the fuel to combust before its supposed to (usually ~15 degrees before Top dead center). Early combustion can push the piston backwards causing SERIOUS PERMANENT engine damage. If your prelude requires premium it will say it in the middle of the tachometer and on the inside of the fuel door

Timber is right... I have a b16 in my Crx and anything over 10:1 compression you need 91 octane and higher... So these engines by Honda:

JDM b16










Some you could get away with not using premium fuel but why hurt the engine over an extra dollar for gas?
