I usually get between 12.5-13 everyday driving (mix) on my 02 2500HD CC 4x4 6.0L. All highway comes in at 13.5-14 on average. I'm not too aggressive, but ocassionaly use a good amount of pedal for passing and what not. I haven't been able to calculate my mpg since I put on my 285's because I haven't calibrated the spedometer yet.

I run all short trips and the motor never warms up, and an occaisonal trip of less than 10 miles for my normal driving. I usually see 10-11 MPG's.

 

My best tank was all interstate driving at about 68-72 MPH and I got 16.5 MPG's.

 

Alot depends on the kind of traffic that you drive in, and the outside temps.

I find if I keep it under 70mph on the interstate I get around 15mpg. I pulled my Vette(3,200lbs) to other day on the car trailer at 70mph and averaged aroun13mpg the whole trip with 4.10 gears.

My cargo van with 6.0 and 4.10's gets anywhere from 11-14 mpg in town and gets worked hard.I tow heavy trailers,drive in town almost exclusively and idle for long periods of time.They get great mileage for the power and size of the engine.

I have a 2001 2500HD ext cab 4x4...The best milage I have seen was 14.5 on the highway going about 80. Normally, I do all city driving and get around 10-11. I will be driving down to Florida today...I figure I will see around 15 if I average 70 mph.

The best I have done on a long highway trip is just over 16 mpg. Other than that I average 12-14mpg. Not to bad in my opionion. They don't show the gas mileage on the heavier trucks for a reason.... :(

My 2003 has 6500 miles and I have never gotten more than 13 mpg (one tank that was all I-75). It will consistently get 11.5 to 12.5 if I am very careful. The diff is 4.10.

This is the reasaon, when people as me what engine to get, I tell them the 8.1l, it gets the same mileage as the 6.0l with way more power. I have the 6.0l in my 2500hd and get an average of 13.1 and a 8.1l in my motorhome, at 20,300lbs and get 8.1 mpg.

      Transmission Temperature Hitting 220s

      By DustMcGrath · Posted

      First of all sorry, I know there are a ton of transmission temperature threads...   My truck is a 2025 LZ0 High (10l89 10-speed) High Country with NHT max trailering package. The NHT package is supposed to have "enhanced cooling."   Normally the trans temp sits around 200. It seems like with any real stress it quickly jumps into the 220s (for example climbing a grade unloaded at lower speeds). I haven't towed much with this truck, but I'm concerned if it gets this hot unloaded.    I've tried a few different things to keep the temps down (tow/haul mode, sport mode, low range when that makes sense) and nothing seems to affect it.    I'm curious if others are the same behavior or if anyone has found techniques to keep the temps down. It seems like it just can't handle reduced airflow at lower speeds, even with relatively light loading.    Thanks!

      2027 3.0 l Duramax

      By cautious optimist · Posted

      I'm at 105,000 miles on my baby Duramax. No issues yet. I hit 31 mpg's traveling through hilly terrain to a project in Colorado. I will buy another 3.0. I'm not concerned.

      Which 2027 engine will you choose?

      By cautious optimist · Posted

      I'm glad you have 14,000 trouble free miles. Frankly though, that's a really low bar. A bare minimum of 80,000 trouble free miles as the norm (rare exceptions always exist) across the whole model year should be a starting point. Good maintenance habits should push these past the 100,000 mile mark with only the most minor of issues. Let's hope GM truly leveled up the quality game with these new engines and exploding engines under 50,000 miles are gone.

      This is exactly the reason our EV has consumed so much of my driving. I don't want to fire up a cold diesel or gas engine just to drive 2 miles up to the store. It's arguably terrible for an engine. If I'm not driving at least 10 miles and don't need to do truck things, the truck stays parked.   Enter the EV. It's immediately heating or cooling the cabin as needed (heat pump). An engine doesn't need to warm up or be driven gently. I can tear off in it with ZERO guilt. Move the car 1/4 mile from store to store and not think "gee, I'm short-cycling a lukewarm engine".   It doesn't idle in a drive-through. Doesn't idle at stop lights. (OK, neither would the diesel, if I let stop-start have its way, but I don't).   Even moving it out of the garage to wash it... HA! It doesn't need to be started just to move 40 feet. I have cars that I will actually put in neutral and push (no start) in/out of the garage or shop if they absolutely HAVE to be moved. My nice Camaros.
