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

Found a set of floor mats for 40 bucks. 
good deal as long as they don't fold in like the gmt900 ones always did, took those weather tech and tossed them in the garbage where they belong, husky weather beaters for the win

I have a pair of weathertech mats in the front of mine. They still look great after 2 years.
they are pretty well known to do stuff like this, the photo is actually a mild example mine folded over much more

The fronts look solid and the driver side test install was flush. I noticed some curling on the 2nd row but wasn’t sure if was due to way they were stored and ‘mgyuver figured’ my heat gun would mold them back if needed.
for $40 that was a steal, that whole set is probably closer to $500 retail
