Unless your engine specifically asks for mid or premium gas, you are wasting money.

I thought 93 was premium.

 

[BlueWeasel]

87 90% of the time, 89 the remaining 10% (just an old habit).

It is in lots of places, but California only sells up to 91 now. I don't know why, it's probably some environmental law. Of course, there are still a few places that carry high octane race gas, but not many.

 

[SuperPickle]

89 usually, but that's because it's the cheapest at the gas station I frequent - 10% ethenol added

 

[spidey07]

91 or higher

I buy regular, because:

I remember seeing some 94 either in New York or Massachussett

any link on how important this number is and why one would waste money if he bought a higher rated gas?

 

[TechnoKid]

depends on what car i'm driving. could be anywhere from reg, prem, or diesel. I try to mostly buy gasoline only from TopTier places like 76, Shell, and Chevron.

That makes sense, California is just screwy.

I can get 110 Octane at a lot of stations here in SE Michigan.

I use 93 octane in my supercharged and 87 in my low compression, OHV vehicle.

one of a million links
costs more, not as efficient if your engine is not designed for it

How Stuff Works

Higher octane prevents the fuel from combusting before it's supposed to in the piston stroke. This is called pinging. If your engine pings, you need higher octane. If your engine does not ping, you don't need better gas and you wasted money.

Interesting factoid. Here in the Rockies, low grade gas is 85 octane. At sea level, low grade gas has a higher octane rating. (Can someone verify?) This has something to do with elevation.
