I recently purchased a 2020 Seirra Denali 1500 w/ the 6.2l.
Last time I gas'd up I noticed a sticker on the inside of the fuel door saying the truck required Premium Fuel.
I read the truck will make adjustments for lower Octane, but Reg Fuel is not recommended for long term use.
Does this engine have higher compression than previous versions? Is this a high-performance engine?
I had a 2014 Yukon XL Denali w/ the 6.2L. Ran it for 150K on 87 Octane w/o any issues.
