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? 🤔

    • One of the few things I enjoyed about my time in the midwest was taking off on weekend drives. Unlike home, where we are boxed in by mountains and water, those rules don't apply to the inland plains. Roads connect and sprawl everywhere. While Minnesota is flat, it's not completely featureless and there are fast moving rural roads with curves and slight elevation changes. I used to relish heading out in a particular direction with no set destination, no curfew, and weaving through little townships, wherever the roads would take me. Along farms, lakes, or through the deciduous trees... It was beautiful in its own way, and the seasons were so distinct there. Fall drives yielded amazing shows of color and contrast. Summer drives rewarded with the and amber evening glow of the prairie (and lots of juicy bugs).    I do a lot of that here in my home state too. But it's much less mysterious/intriguing. I've traveled most roads in the region, and every road that's fun to drive within a good radius of my house. But every drive, even on the same old roads, is still enjoyable. I know where I can lean hard into the throttle or really throw the car into a curve. There are exercise loops for when I just need to keep certain cars limber, and much longer routes to settle in and enjoy a drive and put some miles on. All the mountains and water make for some really awesome roads for spirited driving. But not all my driving is spirited, for example, that's not really enjoyable in my pickup or this Blazer (that's still here...).   Sometimes a good drive is followed by a ritualistic wash before tucking the car away...
    • 'GMAuthority' is reporting the 2027 HD's will have the L8S 6.6L gasoline V-8.  There was some talk here about the L8S awhile back.  Not sure what changes it will have now as it seems the 2027 emissions regulations have changed from what was originally proposed.  The big question will be is L8S just a stopgap for the last 2 years of the current T1 HD platform or will it carry forward to the next generation 2029 T1-2 HD's?    I assume the L8S will still be a Gen. V engine. 
    • New engines will still be using DEF. You just won't have the limp modes occurring when you run out of DEF now.
    • I am not a NOCO fan for a charger I would leave on a battery 24/7. The reason is, it doesn't really float. It waits until the battery drops to a certain voltage and then charges it back up to 14V. It's better than no charger I guess.
    • I would never do anything but lithium.   If the vehicle is stored, just turn the disconnect off. My batteries are completely disconnected form everything in the trailer when my disconnect is off. Trailers don't always come that way as some still keep the CO/LPG monitor on. When mine is off...it is off.   As far as storage temps, LiFePO4 are good down to -20°C. I would store them in a heated place if it goes below that. You can also get heating mats with a thermostat if power is available.   The way the heaters work, if it's below 0°C, if a charge comes in, it is directed entirely to the heater until the battery gets above 0°C and then it allows the charge to go to the battery.   For my Android tablet I use as a display, I can move it inside my house if I was ever in an area that got super cold.
