I’ve always used shell 87. 55,000 on the truck. Yes it’s been decreasing since the lift was installed. My buddy has a 2015 with the same set up and he easily gets 17-18 mpg. Just wondering why mine was so much lower.

I have a 2017 Silverado 1500. I put a 3 inch level on the front and i’m running 20 x 12 wheels and 33 x 12.5 MT tires. I’ve noticed my gas mileage has gotten worse over the past couple days and I’m not sure why. I was used to getting around 15 and it’s been creeping down into the low 13’s. Does any one have any ideas why? Also what’s your setup and what MPG do you get? (I know it’s a truck it won’t get good gas mileage but with the price of gas right now every mile counts)
