What kinda mpgs are you gouys getting with 6.2L and lift?

I cant decided on a 4" lift and 33" - 34" tires or a 2.5" level and 33" tires?

 

Kinda want a feel for real world numbers. I will do some longer trips in the truck and would like to get better than 15 on The interstate.

Thanks guys.

There are multiple threads on this. If you are truly concerned about MPG i suggest not lifting/running larger tires on your truck. However, I believe guys have posted numbers that are better than 15 MPG on leveled 6.2l trucks.

FWIW I have a 5.3 3.42 with 2.5 lift and 34's and still get 20-22mpg, but I have also installed a Hypertech to correct for the oversize tires. Good luck with yours.

5.3 w/ 35/12.5/22's (weigh 100lbs a piece wheel and tire) and 6 inch lift and I average about 15.5 mpg. Tuned with exhaust and cold air. Running ethanol tune i get about 11mpg but i can smoke the back tires! ;-)

My buddy has a 2014 6.2 that is leveled on 34's and his mileage dropped "roughly" 2-3 mpg from what his was stock if I remember right.

Are those uncorrected numbers for the oversize tires? Hypertech is your friend.

uncorrected, of course stock numbers were dead on and 17.5-18 is best I could muster then

I get 15 mpg in the city at the absolute best case with a 5.3, 3.08 gears, and 285/45/22s. The wife doesn't drive like Ricky Bobby either.

I was getting 15 with daily driving before any mods. After a 2" level, 33s and removing the front lower deflector I am seeing about 13 (and yes I corrected the ECU for tire size.)

Finally someone speaks the truth. I don't understand how those who claim high mpg after larger tires, level, lift, etc. Bone stock my 5.3 got 18 mpg cruising at 70. I'm around 14-15.5 cruising at 70 now.

Thats because u drive at 70, and probably have 3.08 gears..18.5mpg for me at 63mph on highway 6.2l , 3.43 gears 35.5" tires 8" lift and tuned correcty for proper mph adjustment. Otherwise stock, engine purrs at 63mph. I really dont care if I got 14mpg, its a 60k for crying out loud lol.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      Thanks for that, yes just because I could I measured what came out just to give me some guidance although I already knew to expect it to take at least 9.5 to just throwing in the whole 10 quarts off the shot and doing a one and done heat cycle to drop out the excess to get to the proper level. I don't recall exactly now what I measured that came out but was less than I put back in, I knew I spilled some on the garage floor but the main part was that I was thrilled in the discovery I did not have to touch my exhaust to flex it down. The gasket manipulating is a pain of course to create that clearance to take the pan out and put back in but its all very doable if one is careful and not forcing the gasket to flex too much. From the quote I got at a transmission shop of 900.00 here in Canada ( never asked at the dealer what they charge ) I saved 700.00 doing it myself after paying for the supplies so that to me paid very good wages !, and I knew what fluid was put in and that I had changed the filter and that the level is correct without any doubts.

      I found a setup that lets me open the cover partway with racks installed, using side-rail-mounted systems for easy access.

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      Typically its said and I agree so far that the engine oil drain plug oring is not required to be changed out unless you see some damage happening to the oring as apparently the oring lasts well. The dealer I have been getting a few parts from never even stocked the oring but instead stocked the whole drain plug that comes with a new oring which for the dealer is easier because they just throw in a new drain plug if there was any question about damage on it as well and charge the customer accordingly but again only if it is needed.    Also a hint about the drain plug oring to help it last vs a risk of causing damage to it, after its been removed and wiped off or washed off ( that is a whole other topic about some solvents damaging orings because some solvent types do ) to make sure to relube the oring with a bit of new oil so that it won't "grip" on the sealing surface of the pan and needlessly stress out the oring. Its no different than putting some oil on the sealing ring of the engine oil filter. So I just grabbed a new drain plug to have on hand although more recently bought just the oring as well but as its special it costs half the price of the drain plug ... !   Since you mentioned the hate to be empty handed theme, I am not sure what you have in the way of filter removal tools as I like using the exact sized for the filter steel 1" wide band with side to side swivel handle filter removal tool, and it can be used to snug up the filter without risk of damaging a filter as well ( its probably a lisle brand I have ). The drain plug hex size is 15mm and I always like using a 6 point socket if I have a choice and with this truck I've been using just a 3/8 ratchet that has a fairly long handle. Do you have a funnel that will work to pour oil in as that is definitely the short coming bastard part about the design with that fill port on the valve cover on such an angle that no normal funnel will even work. There are adapters and things on the market that will set into or screw into that fill port, I didn't want to deal with US shipping as that is all I was seeing at the time so caved and bought a Lisle brand multi vehicle fit adapter funnel kit and it really works well but there are much less expensive adapters out there that work in conjunction with an off the shelf funnel that would do the job also. Now that I have it, I like how it works and works so slick with the shape of the Amsoil 1 quart containers I have now switched over to. Whatever you do, have a funnel system of some sort as you will be swearing if you dropped the oil and then realize you have nothing to properly pour new oil in without spilling it all over the engine !.     Other comments, quite a bit of oil flows out down the filter when its cracked loose due to the housing above the filter so let it dribble down the filter until it slacks off flow and then remove the filter to create less possible mess. It seems these engines can sit for quite a while and drip and if you have time let it sit there and drip out of the engine as much as it wants. Also a good time to grease the 9 zerks on the front end, that's my typical practice anyway to grease the suspension and steering each time I change the oil. And remember to reset the oil change minder ( not something I am used to doing with older vehicles and equipment ).
