What did you do to your NNBS GMT900 Tahoe/Yukon Today?

what on earth is 88? is that some e based stuff, or just out of order mix between 87 and 89?

I honestly don't know... It's a blend that I've only seen available at various Casey's gas stations.

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.

Do the math on your fillups, it might be cheaper to use 87 then a bottle of additive to get the octane number where you want it.

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