Quickie: Yr/model; oil you you use, and how often do you change it...

 

 

Just wondering. GM told me every 5000 miles, but that doesn't sit right with me. I haven't had a second oil change yet (guy I bought it from never drove it, had 8 vehicles) but should be soon.

 

08/silverado/I switched to castrol gtx 5w-30 from factory oil/ 10,000 extended guard oil filter/plan to change every 3K miles.....

 

Before I go on, why do they say 5000 miles? That doesn't seem right with standard conventional oil.

The 3000 mile oil change is out dated. The jiffy lubes try to perpetuate it because they sell more oil. ILSAC GF API-SM rated oil is very good today. Much better than oils of the past. You won't find a bad name brand oil today.

 

Your truck has an oil life monitor. GM recommends that you follow it. Or at least go 5000 miles. And use a good filter, AC Delco. Never use a Fram. they have cardboard end-caps. The extended guard is their best filter. I still dont trust them.

2007 Classic HD2500 with 24,000 miles. I use Pennzoil Platinum 5w30 and AC Delco PF48 filter. I change every 3000-3500 miles only because I don't drive it all that far....sits a lot, so I change it about every 4 months or so....changed the coolant (dexcool), rear end oil )castrol 75w90 synthetic) and tranny fluid (pennzoil dexron VI) all at 21,000 miles. Wanted to do it before winter set in and it is right at three years old.

08 Sierra 5.3L, Mobil 1 5W30, K&N Oil Filter, changed every 5000 miles or annually, whatever comes first.

09 Envoy Denali 5.3L, same as the Sierra -- but usually ends up getting changed first. I put more miles on it than I do my truck.

For my previous truck:

2007 GMC Sierra 5.3L Changed oil every 5000 miles. Whatever oil the GM Dealership was using. (regular dyno oil, 5w30) Oil Life monitor usually still had 40% left on it when I changed, but changed it 5000 miles regardless.

 

 

For my current truck:

2008 GMC Sierra 2500 Duramax Diesel: Have not had to change the oil yet, but I anticipate changing the oil every 5000 miles, or twice a year. Will use whatever grade the owners manual calls for, (probably Shell Rotella as far as the brand goes) Or I may decide to go off of the Oil Life Monitor. We'll see.

 

I don't use any fancy shancy Synthetic oil, but if I did and when I used to, Mobil-1 full synthetic was my choice.

Every 3000mi. Castrol Syntec 10w30 since new. Either NAPA 1522 or the current GM Filter. 173K on the clock, 40psi on idle and 60 off idle.

 

My antiques get it every year regardless (unless the 3k rule applies).

 

Yeah, GM has come up with a computer algorithm that gauges the oil. This never test the oil for contaminates thou. A clean engine has had the oil changed at 3k or less every time. High mileage oil changes make for gunky tear downs (which is usually why it makes it to the tear down bench).

 

Just my 2 cents.

2009 Sierra Denali.

 

Haven't owned it long enough to change the oil in it yet but I'll change it around 5k miles.

 

I'll use Mobil 1 with a Mobil 1 filter. Then I'll change it around every 6k to 8k miles depending on the type of driving I do.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
