I honestly don't know... It's a blend that I've only seen available at various Casey's gas stations.
What did you do to your NNBS GMT900 Tahoe/Yukon Today?

I've heard 88 is only available in the higher altitude states. I've never seen it offered in the northeast.
“Unleaded 88 is a fuel for gasoline-powered vehicles containing 15% ethanol. It gets its name from its octane rating of 88. Unleaded 88 is often referred to as E15 because of its 15% ethanol concentration.”

Yep. It’s right there next to regular 85.

I've never used black magic in a bottle. What are some quality additives?

You can get 88 here in WY.
I live at about 5,000 feet elevation.
Many stations even offer 85, which I have never seen at stations in lower altitudes.
But, 88 is still too low an octane level to use in my Yukon with the 6.2.

We have 88 here in WI as well. Good bang for the buck. No real mileage hit and a touch better running.
What did you replace these with? Standard (non-adjust) black leather headrest?
I went from stock 2011 non adjustable to adjustable from earlier years. like 07-08
yeah normal yukon denali black leather.
I think this one said Escalade on the listing. the leather texture is a touch different. but I also haven't cleaned it and added any conditioner yet.
