we are down to 90 octane in alaska, used to have 92..
but the reasoning behind our change was that we hadn't violated the air act in years.

 

Running regular would cause serious damage via severe detonation on an engine designed for premium. Now in case of an emergency you can fill up with regular but it is strictly advised that you don't accelerate aggressively at all, just lightly cruise until you get to a place where premium is available. It is also recommended to try to completely use all of the regular before refilling so as not to dillute the premium fuel if you plan on driving aggressively. I don't think that gas stations would actually do this because it would cause them to lose business even more than they are now. Plus it's unamerican. Nuff said.

 

Sales on premium fuel are down. But look at it this way. Locally, we have Sunoco 93, BP (Amoco) 93, Shell 93, Texaco 93, and Sheetz and Get-go which I won't use. If BP and Sunoco stop offering 93 then I will exclusively go to Shell as I'm sure many other people will. ( I used to exclusively go to Sunoco when they offered 94.) This means all profit and a big sales boost for Shell, and a virtual monopoly on the 93 market. Do you really think BP and Sunoco will allow the courtesy of giving Shell all the power and sales?

 

I cant find 93 for the life of me (but I havent tried too hard in MN)-I usually get the 91-its still everywhere here....oh, and E85-when are we going to get that conversion?

 

Regular is a no no in Evo's.

 

If my car was aftermarket tuned for 93 then clearly there's a need and I'd find a station for that grade. I would be surprised if the ECU was programmed to allow for knock with regular gas, more likely I'd expect to lose some performance. Mitsubishi would hopefully have thought ahead when programming the ECU on a mass market vehicle.

 

what are the "some gas companies?" ..i'm sure this won't actually happen

 

IF Evo drinking Regular = needs octane booster shots.

 

Water/meth injection lol

 

The Evo isn't the only car on the road that need 93 oct.I don't think oil company's are going to ignore that much of the market.

 

i would never use unleaded on the evo

 

Lots of luxury cars require premium. My Si requires premium. I doubt they'll take 93 off the market, there are lots of rich folks around my neighborhood that'd be very pissed.

 

so you run leaded race gas everyday?

 

This is all speculation and wont happen in your driving career.
