draperfish replied to Sharp780's topic in 2014 - 2018 Chevy Silverado & GMC SierraYeah, my 2018 does it too, curious as to what it is but figured it's normal, makes sense if it's emissions related.
I'm on a road trip from Arkansas to Florida, my 2018 CC Z71 with 6.2 and 3.23 gears and BFG KO2 275/60r20 tires averaged 20.2 mpg over 1050 miles (computer was showing 21.5). I'm running 93 octane and cruise was set between 70 and 75 for most of the trip. Odometer was around 5,500 miles when I left, around 6,800 right now. I'm gonna check the mileage on the way back too.
It depends on the configuration of the truck, regular cab, double cab, crew cab, 2wd, 4wd. Google 2018 GMC Sierra Owners manual, all the tow ratings are listed in the owners manual. Crewcab 4WD with short box and 6.2 engine is rated at 9,100 lbs same as the same truck with the 5.3 engine and 3.42 gears.
Surprisingly enough mine was purchased through the company I work for and came with a 5year/100K mile fleet purchase powertrain warranty. 36K mile warranty is ridiculous! My 2014 Ram 5.7 had to have lifters and cam replaced at 75K miles, it's sad nobody can built a bullet proof engine anymore.
My boss runs regular in his Yukon XL Denali, no way I'm not running premium in my truck! I'm too OCD about engine noise and in my brain it's pinging on non premium gas (even if it's only in my head).
The online window stickers for all the trucks I've looked at online are generic and don't show all the included options, the online window sticker for my truck showed 3.08 gears for the 5.3 under standard equipment and showed the 6.2 option, the actual window sticker shows the 3.23 ratio as an included option. I didn't think the 3.08 was an option with the 6.2.
