First Oil Change

My 2005 Sierra 1500 Crew Cab has 5800km (3600 miles) on it. The dealer said that the truck has the Oil Life Omitoring system on it and the DIC will tell me when the oil needs to be changed, usually at about 5000km for the first change.

 

I have not had a message saying to change the oil on the DIC yet and am just wondering at what mileage the message will come up? The driving has probably been about half city and half highway driving with no towing.

 

Thanks,

Chris

The Oil Life Monitoring system uses an algorithm to determine when the message comes on, see here: http://www.gmtechlink.com/images/issues/may03/TLMay03e.html

 

Personally I never use the thing. Somewhere b/t 3,000 and 4,000 miles I change my oil; that's about every 10-12 weeks. Oil Life message comes on well after I've change the oil. For the price of repairs/new truck, the oil's cheap insurance.

Plus it's brand new - you should definitely change it. Mine had a lot of metal shavings on the plug.

On new cars, I always change oil when I get it home, 500 miles, and every 3000 miles after that. Like was said above, *cheap* insurance, and effective. You get all the leftover metal out of the engine after assembly and give it the best chance at a long life.

 

I think the oil monitoring system is there just to extend the dealers pocketbook :seeya: "Change it every 15k miles, it's fine... oops, you need a new engine!"

I have been using the oil life monitor on my vehicles since 1993 and never have had a problem. Usually get 120000 mi. If it wasnt any good i wouldnt trust it to to 94 ZR-1 i bought new where the replacement engine is $25000

I would go ahead and do it or get it done at your current mileage, since you've just undergone the breakin period. After this change, go ahead and use the oil life monitor, it won't hurt anything. Some people would have you believe your engine will blow up at 3,001 miles! Personally, I run 6k between changes. Just did a change today, that stuff sure does come out dirty. Kind of made me feel fuzzy all over seeing the nice clean oil on the dipstick again! Anyway, I'd go ahead and do it now, and maybe a second change after another 3k, and then go by the oil life monitor if you want to, certainly won't hurt anything.

 

If you are going to follow the oil life monitor, I would insist on the use of a premium motor oil. I'm working at a Chevy dealer for the summer, and we use this service pro s**t that I wouldn't want in my lawn mower! You don't need to use synthetic, however, I wouldn't want to run 12k miles on that service pro crap we use at the shop!

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.

      Electrical Problem - solved

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
