Premium is $1 more per gallon here, so long term you are spending more on fuel. That said, I drive around averaging 10.3 mpg in a stock 6.0 2500HD Sierra and a stage 1 cammed/header 6.2 Cad Escalade EXT with similar mpg makes the 2.7 turbo mpg and power look impressive to me. Luckily I don’t rack up the miles like I used to.

In TFL's video of the 2.7T break down the engineer stated it was designed for 87.
