    How many hours can be expected out of the newer GM trucks ever since they put the digital hourmeter in the dash? Now I understand its different for some because of the way people maintain their trucks, but a truck that has a regular oil change. Just wondering. My truck has the 8.1 Liter with 63,200 miles and 3250 engine hours. Is that a lot, a little?

    I'm at about the same hours as you... 3,350... with around 76,500 miles on my '03. I'd be interested to know how many hours these engines can be expected to go...???

    Lets you figure out the average speed of the truck as well. I think the higher the ave miles and the lower the hours on a truck, the more desireable it would be for me, lotsa highway miles.

    On the truck or on the engine specifically?

    I'll give you an example on the engine if thats what you're after. The 8.1's are just one of the GM engines used in industrial and remote power generators (for agricultural use for example) and in those instances they're well know to go over 10,000 hours running at 60%-80% maximum load and running 24 hours a day 7 days a week. And they do so consistently with only a shut down for oil changes/regular service.

    Of course it's not quite the same situation as the engine in a truck with the different demands placed on it vs in a continuously running generator but I know of a few 8.1 equipped trucks that are nearing 8000 hrs and still going strong.

    But like anything else, correct maintenance and treatment makes a major difference to the lifespan of anything.

    I know what you are saying, as you can tell mine idles A LOT. I never shut it off during plowing. It gets started in the garage then shut off when I get back home. I take the keyless entry off the key ring when I walk into a store or something and leave it running.

    On the engine I was talking about. I also run synthetic in all of my trucks and they get oil changes at 3000-5000 depending on how hard they are working. How about the 6.0's B&B?

    The 6.0's will go 200K without breaking a sweat and I've personally witnessed them go 250K with nothing but routine service. Can't give you any specifics on hours though but there's no reason they won't have similar numbers to an 8.1. In fact they're actually a more efficient engine overall than an 8.1 so in theory they should actually live longer, all outside variables being the same of course.

    My 2000 6.0 has 127k miles and about 4400 hours on the meter. No issues with the powertrain, she gets regular oil changes every 10k with Mobil1 5w-30 and filters every 5k. I use about a quart between filter changes.

    My 04 Silverado had the cluster changed out a few years ago and the hours were never right and now they just reset. Anyone else ever have this issue?

    Yeah,it was a recall on those clusters if I remember correctly.My 04 Jimmy Dmax had it changed out.One day almost all the gauges went wacky,including the speedometer---quite a ride doing 120mph in a 30 zone.:dizzy:

    We have an 01 dually GMC 6.0 with 75k miles and a hair under 5000 hours. It's uses 1l of oil every 1k. Truck still runs really good for only being used as a salt truck since new.

    My 07 Duramax just rolled 2000hrs after 51k miles. Thought it was kind of high myself but i do idle quite a bit... if I run in the store for a second, the truck stays running.

    My hours reset too! Happend on a 2005 chev 3500 dmax.
    I installed a new radio and when I noticed the reset
    So if the hrs look to good to be true its probably not true.
