...you can't fill the tank at Costco, because you have 5Star tunes for 87 octane

What are these "octanes" you all are talking about? Don't you just grab the green stuff and go?

I thought 85 Octane was weird, so I looked at your location... Yeah.

Normal places that have oxygen in the air sell 87 and 91... 89 is a mid grade at most.
93 is the premium if you're lucky.

There's one station I've seen that has five different grades and I don't believe that included Diesel or Kerosene.

Most places here have 85, 87, and 89. Quite a few have 93.

Unless you go to a Kangaroo station, the octane stuff has a green handle. I almost made that mistake.

I hit a station like that once and I thought they just blend the 85/89/93 to make the in-between numbers.. I think it was NV or UT and I was driving a rental..

Some brands refine the different grades and some only refine the lower and upper grades and blend them at the station to achieve the mid grade

This I am almost 100% is not true. I'm no mathematician but the mixture would have to be adjusted from week to week if not sooner as the fuel is never the exact octane it's advertised as. It's allowed in a specific range of tolerance, but if you had an 87 at the lowest end and a 92 (available in some states) at the lowest end then that would make for a failing grade 89. In case you're wondering yes, I am HAZMAT certified and messed with fuel trucks/fuel filtering/distributing systems in the military

It is 100% true. I manage a 76 station in CA. They refine 2 grades, 87 and 91. We only buy 2 grades and only have 2 storage tanks. At the pumps the 87 and 91 are mixed 50/50 to provide the 89 we sell. Some brands deliver all 3 grades and do no mixing at the pump.

That's really interesting! I honestly never would have guessed that but you learn something new every day In the Army we only had one "octane" and it was diesel
