93 octane in Utah?

[Austin Elkins]

Anybody know where we can find 93 in Utah? I know they say 91 in elevation is equivalent to 93 elsewhere, just wondering if we know of anywhere that sells 93.

We see the same thing here in CO. Our regular is 85.

Nope. But the Raptor runs well on 91. I am getting 92 in the PNW and don't notice the difference.

The general rule of thumb is that for every 1000 feet of elevation above sea level the RON decreases by .5 due to the lower air density. So an engine that requires 93 in LA will only require 91 in Salt Lake (elevation 4200’). That is why premium is 91 in Salt Lake, Denver, etc., but 93 in LA, Seattle, etc.

If you have an engine tune that requires 95 at sea level, then you’ll need 93 in SLC. The easiest way to achieve this is by purchasing racing fuel and blending it to your desired level. Google “racing fuel” and you’ll find many locations in Salt Lake.

You kind of answered your own question. At elevation you can use whatever is listed as “super”. On the east coast, some places mark mid-grade as “premium”. Fortunately they also sell 93 in most of New England.

You can mix race fuels with lower octane if you need.
