Is there really a big difference on everyday driving between the 5.3l and the 6.0l?? I am looking at both of them to purchase. I will only be towing a maximum of 3000lbs. What do you guys think? I have drivin the 6.2l and it is way crazy fast and powerful. Don't need all that.

The 5.3L will return far better fuel economy and handle the 3,000lbs very easily.

I have a 6.0 in my 1 ton work van, and I think its a great motor. The truck is loaded all the time with prolly 3,000 lbs of tools and equipment, not to mention the ladder rack. It averages about 12 mpg like that. 105,000 miles on the clock and nothing done to it. Still has plenty passing power too. I say go with the 6.0

If gas mileage isn't an issue with you go with the 6.0. You won't regret it. My 6.0 returns a range of 11-12 (when towing ~10K) to 15 (all highway). Hope this makes your decision a little easier.

 

FWIW, even with the huge hit in the pocket the gas mileage did to me, I still don't think I could have done better. . .unless I started looking at a D-max.

My buddy got a 6.0 max in a half ton ext cab, and it screams compared to my 6.0 in my 03 crew 1500hd and he gets 17mpg on the highway lightly loaded. I would go with the Max and not limit yourself, if i knew what i know now, when i purchased my truck i would have stepped up to the big block.

Definately the 6.0 I've driven a 5.3 sivlerado before and my avalanche is way faster, especially with the cold air intake. Still thinking about an exhaust though. The 6.0 with a couple upgrades will get you close to the 6.2 and with much better economy.

I would definitely go with the 6.0 Vmax if you're going with a half ton. I've owned both (2003 EC with 5.3, 2007 CC NBS with Vmax) and there is no comparison. I drove both the 5.3 and 6.0 Vmax CC models at the dealer before I purchased and the Vmax was much stronger. The mileage ratings on the sticker are the same for 5.3 and 6.0 for 2007 Crew Cab models (15/19). I'm getting 13 with pure city driving, 17.5 pure highway and average 15 with an Edge Evo programmer on the highest power setting. I'm not sure how that mileage compares to 5.3 mileage (in the real world).

Ok, so that's better than what I'm getting. I think its worth the extra gas $$ for the extra power of the 6.0, but I only drive about 10k miles per year.

6.0L will be much much stronger but suck down gas, 5.3L will still do good in power but not as good, and get 3 or so mpg better. 6.0Ls sure sound great though!

This is posted in the HD forum where 6.0 is the smallest engine you can get so may not be much advise on the 5.3. It is hard to compare the gas consumption because most 6.0s are in HD trucks. These are much heavier trucks than the 5.3 1500s. I think the difference in gas mileage is do to the additional weight of the vehicle it is installed in and not the 6.0 vs 5.3.

More power is always better.

true, very good point. I noticed some NBS trucks with the 5.3L would get a couple mpgs better than with the VortecMax though

      6.2L L87 Powertrain Engine Noise (Lifter Failure) Question

      By clowe1243 · Posted

      Got the truck back today.  Called them yesterday to get an update, and miraculously my truck is finished?!?! The $13k out the door was complete bullshit!  Ended up being over $14k.  They added some bullshit service bulletin that I cant even find, where they replaced my radiator without telling me or asking me, and charging me for it.  Need to do more research into it, cause they leaked the first delivered radiator was ran over by FedEX.  Sounds like bullshit to me. 2.5 Months for an engine swap, which ended up being remanufactured, not new; ****ing ridiculous.  Brakes are squishy as hell, not sure if its from sitting.  Will give a couple days to see it that figures it self out.  GAVE IT BACK TO ME WITH 1 GALLON OF GAS!  Just filled the tank the day before drop off, more bullshit.  My dash cam SD card was formatted, not really much I can do about that. 3 year, 100k GM warranty at least.  Time to sell it and say **** off to GM.  Bad experience.  Cant wait for the survey email to come through.  Overpriced Raptor R, here I come!

      If I forget the phone in the truck, and forget the truck in the phone, and reconnect.  It works great for the day.  Truck sits overnight, and the next day is a no go.  It will connect Android Auto via usb cable, but not bluetooth.   Ive tried Everything in this thread so far, and nothing works for more than a day.   I think I might have to go to the dealer and have them flash the pcm.   thanks for all the suggestions guys. 👍

      primary drive belt tensioner

      By Bill Lemmond · Posted

      2022 2500HD Crew Z71 Duramax single alternator.  Recently had the primary (water pump / fan) belt tensioner pulley bearing to fail while hundreds of miles from home of course the plastic pulley melted and belt shredded which took out some wiring. Found a replacement tensioner assembly and belt to continue now would like to find a replacement for just the pulley and bearing to have a spare assembly in case of a repeat, the rest of the tensioner is fine. Has anybody here found a correct replacement part for just the pulley and bearing? Any help is appreciated.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      By Atlas · Posted

      +1 for the 3.0   Perfect for 1500 pickup towing duties.   Perfect engine for a 1500 pickup period. Huge torque at stunningly low RPM makes it feel a lot lighter than it is. The fuel mileage is insane for a tall and heavy 1500... 30+ on the highway. Mid 20's around town.   It's probably not perfect if you bought a 6.2 for the braaaaaaapppppp V8 noises and wrapping it out to 6k. The LZ0 acts and sounds like a small turbo diesel and there's nothing you can do to make a small turbo diesel sound like a big one, and you can't make an inline diesel sound like a V8 diesel/big Duramax. It's a different driving experience altogether.   Drive one, I think you'll like it, though...

      I'll bet your truck lost the bearings on a roller on 1 of the lifters, and now is wiping out a cam lobe.
