Surprising Loss of MPG After Leveling Kit Install - AT4 with 5.3L

[ullose272]

I used to get 10.0 mpg, now I get 9.0 towing the specific trailer and load mentioned above.  FWIW, I could give a damn what I get as gas is damn near free at current commodity pricing.  I just wish I had a larger fuel tank [emoji6] .  Even if gas pricing raises up to where it should be I could care less as it's a minimal/insignificant amount of money.  I'm actually attracted to vehicles that have the "worst" fuel economy as they generally offer higher performance.
 
I track my Z06 Corvette on a regular basis and I get right at 3.8 mpg on track which only allows me to run ~40 minute track sessions on a full tank of fuel.  I wish the car had a larger capacity so I wouldn't have to pit so frequently/early for fuel.  FWIW, I get right at 24 mpg from the Corvette cruising down the highway with the cruise set at 83 mph with 650 hp/650 lb-ft available. 

Mpg increases range[emoji6] i dont care about the cost of fuel, i car that i can go 500+ miles to a tank

FWIW consider yourself lucky. I lost 2mpgs with just the level and tires. Most loose 3mpgs.

REALLY? jeez I normally per the DIC would average 16-17 mpg with mixed city/highway. Now im sitting at 13-14.5 on the regular. 2'' level with 33x12.5 im shocked as well that it would make such a difference. I thought it was attributed to me opening the exhaust flapper.

Pony up and buy a 63 Z06 tanker

Yessir.
These trucks like the lower factory rake when it comes to mpgs. One thing you can do to gain maybe a mile or better is a hard bed topper. That has always worked for me. I just don't consider it as an investment as it really doesn't matter to me.

Good to know, I have a GM soft bed cover on right now. Granted I also removed my lower air dam too. Didnt like the look with it being leveled. Oyeeee.
