The motor has probably lasted fhis long because GM isn't messing with it. Keep that AFM crap out of these trucks

AFM, DOD, and DI are all death of a engine.

A 6.0 HD is as close to maintenance free as it gets with bulletproof reliability built in. Power-wise, I'd take a Dmax any day but the way I use my truck (excessive idling, starting, stopping, cold we

Lots of good advice here. As stated, you're not going to be able to improve the MPG enough with basic mods to justify the cost of those mods. Save your money to buy more gas, haha. You can expect simi

MPG will start slowly coming up after break in. I started noticing the engine working better at around 3200 miles. Staying below 70 on the interstate should net close to 15.5 to 16.5 mpg if your car

Agreed. I used to be on the direct injection bandwagon, because of the increased HP and MPG the 5.3 & 6.2 received when they went to DI.....but now that the jury is out, I'm glad my old dinosaur 6.0 doesn't have it, haha.

Why I went w/ ordering a '17 even though I didn't really have any complaints w/ my '11. I didn't want to have to deal w/ a high tech gadget a couple of years down the road.

well no shit sherlock.

Ive owned a truck for the last 25 years. Was i expecting 30mpg? No.

 

I "was" hoping for a bit better than this tho. Considering this motor (as i said in my original post, i had back in 2002) has been around for YEARS, you'd THINK they'd do something to make it just a TAD better than it is as it hasnt changed since the last one i owned.

 

My brother in law just bought a 2017 1500 LTZ with the 6.2 and 8 speed tranny, with full towing package and gets 17-18 around town, and 22-24 on the interstate.

 

So, no i dont expect since i own a truck to get Toyota Camry fuel economy, but they could DAMN sure with all the BS theyre doing to motors these days, make this one get better than 12-13.

Th real difference is they put VVT in this motor around 2009 I believe. The 4.10 ratio is killing the mpg on these.

The LY6 had VVT since 2007.... also when they went to the GMT900 body and the 6L90E trans. The L96 came out in 2010 and it's the same engine with larger injectors accommodating flexfuel capability. The 4.10 gears don't kill the trucks ability for fuel economy, but rather the weight and aerodynamics similar to that of a brick do.

I've been driving direct injection cars, mostly European, for years. DI engines do require better fuel and oil. Most, if not all top tier gas have anti soot additives to reduce carbon build up on the valves after combustion (even though the fuel never touches the valves during injection, they use the VVT as a type of egr along with other recirculated exhaust gases)

 

Oil also becomes more critical. Properties such as NOACK. Long and short the oil in vapor form cooks on the the valves via the PVC system.

 

Countless 6.0's are at construction, landscaping, delivery, you name it business. I also bet they get jiffy lube oil changes and the lowest cost gas that can be found.

 

Kind of makes the good ole 6.0 make sense doesn't it.

 

I wish you could get a 6.2 in the HD trucks though.

As I say... most HD trucks with gas engines are fleet customers. If GM makes their truck more expensive to run and maintain then those guys buy something else that isn't.

I like my 6.0, BUT as i said in my original post, i had a 6.0 back in 2002, long before the items you guys talked about were introduced, and even in 2002, the fuel economy sucked. LoL.

 

Its actually getting a tad bit better now with 3500 miles on the clock. My to and from work using back roads (45-55mph speed limits), and i'm up to right at 13.5-14 mpg.

 

Headed to lake hartwell this coming Saturday for a fishing tournament so i'll get to see if my hwy mileage has improved any.

My last tank of E85 netted me 11mpg with a 50/50 split of city/hwy.

I filled up with E10 (regular unleaded) about 3 days ago. Took 32 gallons so there was a little bit (12.5%) of E85 left in the tank. My mileage is up to 13.6mpg so far. Next tank of E10 should be better as most of the E85 will be gone.

Almost ready for my first oil change too. Mobil 1 5w30 is going in.

      OCI, not when but why?

      By Grumpy Bear · Posted

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.

      My First Project and GMC has me stumped

      By whenindoubtuseahammer · Posted

      Good evening. I was lucky enough to get passed down to me a 2007 GMC LBZ that was my great uncle's. While the underside and rockers are more or less gone I feel like with time I can restore it to working order since it only has 110,000 miles and he put nearly every option he could get without getting the new body style since he did not trust DEF. So far I have done everything I can think of but when I put the key into the ignition nothing happens. I put 2 brand new batteries in it. Cleaned the terminals. Check all the fuses and relays and they all pass with my multimeter. I know I'm missing something that I just cant think of. The only odd thing is the OBD2 port works which makes me think its not the mega fuse. Any advice would be greatly appreciated.

      Looks nice. I still have my 2000, 1500. Bought a 2025, 1500 for retirement. Feels solid. These trucks have a bad rap on the internet. My brother has a `24 1500, 5.3 with 52,000 miles. No problems at all. Mine hasn`t either but mine`s only at 12,700 miles. Have seen some of these things with 100,000 miles with no problems.

      Howdy! New to the forum of course! My name is Casey, just picked up a 2024 high country midnight edition. First “new” truck in 24 years for me. Driving a 1998 Z71 since 2002. Have been on the GMT400 forum with lots of good info and help there. Nervous about driving these newer trucks and all their electronics…. Did a lot of work on the Z71 myself over the years. New truck is definitely a nice upgrade after 24 years. Photo of the old and new, still keeping the Z71 - has 320,000 miles on her and still running well!
