More tire replacement activity in a short time than normal. 
 

I did not see any report of transmission fluid and filter replacement, nor the differentials and transfer case fluids being changed in 140k miles. That alone would rule it out for me. I don’t really like the first oil change being at 5000 miles either. The interval grew to 7500 at around 40k.

What would you recommend for the first oil change?

 

My dealer gives 6 oil changes with the purchase of a new vehicle. I used the first one at 1100 miles after break in. Had the 2nd one at 6700 miles. Currently at 8336 miles and plan on 5k mile intervals or near there.

First one at 1000 miles or so is a reasonable approach balancing cost, hassle, and the goal of quickly clearing particles from break in or production contamination.  If I was only going to do one early oil change before going to the regular interval I’d pick a bit earlier at 300 to 500 miles, but that’s not based on any deep experience with doing oil analysis like some of out other posters here have. 
 

Since I do my own oil changes and keep my vehicles in the family for 20 to 30 years, I’m conservative about early oil changes on a new vehicle. On my 3500 hd and my new 4Runner I did first oil changes at 300-500 (truck was early at 300 because i discovered a dented oil filter), next around 1200, then 3750, and every 3750 after that. I’ll go up to 5000 on a highway trip if it means i can do the oil change at home rather than on the road. I see every trip to the dealer as a risk, especially away from home. 
 

Nothing wrong with a 5k interval for most trucks, especially if a lot of the miles are highway. My truck gets a lot of short trip work between the highway trips, and some years only 4k total miles, so 3750 is my default (half of my 7500 tire rotation interval). 
 

My oil level barely drops perceptibly in 3750 miles.

I also did my first oil change at 800mi. And I also go only about 4k now. Plenty of shorter trips for me.  I have now had my truck 2yrs almost exactly and it has 11k miles only.

I'm not necessarily in agreement with the practice, but my former employer of over 35 years replaced hundreds of trucks at 100,000-120,000 miles every year. The first and each oil change afterward was at first 5,000 miles and they eventually went to 7,500 miles and have got great service out of them. They did multiple studies with oils and filters by analysis. They even tried Baldwin filters and decided to go back to WIX. I quit buying new auto's some years back and buy a 1 to 3 year old now. However, I would probably change at 1,000 and again at 4,000 and then every 5,000 so it's easier to keep up with by the odometer.

Scores of fleet vehicles go the whole 7,500+ interval and get the cheapest service parts available and go 200+k miles. Spend some time looking at BIOTG forums and people that submit their oil reports to Blackstone labs and you'll see the modern Dexos 1 Gen 3 oils are good past 15k.

 

I know every car guy loves to change it every 42 miles and keep it nice for the 2nd and 3rd owner in a few years, but I'm just playing devil's advocate that the statistics say it's overkill. Freeport-Mcmoran or the City of Insert Name Here is going to have a blue collar in an HD idleing it 6-12 hours a day for 100,000+ miles while it gets computer triggered PM services with the cheapest stuff they can get bulk. Then, after it goes to auction, it's going to end up a landscrapers truck for it's next 200,000 miles getting the same or worse treatment.

 

Meanwhile, you'll change your oil every 5 miles and give it the best parts and it will spin a main bearing at 42,000 miles.

 

That's just how this stuff goes unfortunately.

That oil change history isn’t horrible, but it isn’t great either. Changing to 7500 when the warranty ran out and never changing the transmission, transfer case, and rear differential fluid in 140k miles shows you the kind of owner it was. The transmission neglect would be a no-go for me.

Looks to me like an owner who knew they were going to get rid of it so they didn't care, buy another one.

Interesting post and viewpoint. Seems based on the idea that no matter what, the vehicle will go 250K and perhaps well beyond. If anyone is looking for me to disagree, I won't because given enough tenacity it will. :) 

 

Vehicles are like wives. Care well for them and they will not complain and be happy little campers you will live a long life of peace with. Don't care for them well and you can still live a long life with them. Just not a pleasant one. And yes, I do have a preference. Oh, and yes, you can care very well for them and still have a stinker. :crackup: 

 

How we care for a thing is only half the equation. It's the half you have an influence over. If the half you don't is problematic it says NOTHING about your efforts. This post implies that a 'stinker' PROVES that care doesn't matter. 

 

You sure? 🤔

    • I’m definitely interested to hear the end result here. 
    • 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.
    • 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. 
    • 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.
