I know this may not be true, but it seems that 91 octane (Premium) is very tough to find; gas stations just don't carry it. I can find 93 octane (Super Premium) everywhere... of course for additional cost. Since my car (and many on the road) requires 91 (or higher), one would think 91 would be prevalent. It seems easier to find diesel pumps than 91-Premium pumps. :confused:

I'm not bitchin' about the additional 5 cents per gallon or whatever, just curious to what's going on.

91 is our top out here in Colorado and I think most mountain states or states with a higher Alt then sea level. Thats all I put in my truck.

91 is also the top octane you can get at the regular pumps out here...

Plenty of 91 octane rating in my area. The typical station has 87 "regular", 89 "mid-grate", and 91 "premium" at each pump. Diesel on the outermost pumps is common (mostly 40 cetane, but a few offer 50 cetane premium diesel).

Only a few stations offer 93 or better octane rating that I've seen, but I typically don't look for it.

One station I frequent also offers K1 and 100LL offroad pumps.

Plenty of 91 octane to be found I got gas last week for my Acura 91 is what it burns. I got gas twice while down in Southern Maryland $2.69 at WaWa & Sheetz for it. I refuse to get premium gas inside DC unless I need to:eek:

I was wondering about that. I just spent 8 days in Utah and drove up to Yellowstone and then back down to Bryce Canyon and never saw 93 octane once. My brotherinlaws 6 cylinder Range Rover had a very tough time in the mountains. Lot of pinging and down shifting. Could not come close to the Ridge on the open road.

Try Sunoco stations. They are the only one by me that carry all four grades. Everyone else seems to only carry the other three.
