What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

[the 18th letter]

Since I drove the Hoe to the orifice today I topped up on the way home. E85 is the same price as on Monday, but everything else went 25 cents higher:

Gas prices in Colorado are bucking the national trend, which is on its way down.

Unleaded 85 is the grade I couldn’t think of. Ran a tank I got out of Marayland or VA. We don’t see that at all here in NJ

It's our "regular" "87" formula for high altitude. There are arguments that, since the air is less dense, less octane is needed, but I think that's disputable.

Your regular unleaded is 85 octane?

Yup. High altitude Regular. We're around 6,000 ft AMSL.
