Higher mile L87

[BacDoc]

For oil changes I go off the dash. I try to change it around 15-20% oil life left.

I'm about 60% highway and 40% city driving.

This honest real life reply is probably the typical use and history of these vehicles.

Some of us on the forum are enthusiasts and change the oil every 4-5k miles, pay attention to the oil temperature, coolant temperature etc.
Disable auto stop, AFM, install catch cans and run premium fuel.
Check the oil between oil changes and some even look for “Swarf” and get oil analysis.

The majority of the people who buy these expensive trucks, just change the oil when the OLM lights up and just put gas in the tank when it’s close to empty, regular fuel at the cheapest price.
They bought the vehicle for the space, amazing smooth quiet ride and the power to haul cargo or haul a$$ when needed and do minimal maintenance.

Hundreds of thousands of these vehicles go for 80k+ miles without any problems and unfortunately the small percentage of vehicles sold can have major engine failure.

This is still better than blindly guessing at a mileage interval, because
the Oil Life Monitor differentiates between 3000 cruising highway miles vs 3000 stop'n'go urban miles.
I do remember when GM's advice was to change the oil @ 15% remaining vs 0% remaining.
You can also add a pessimistic skew to the OLM and change the oil sooner, @ 20% or 25% or 30%.

Regardless, unless your vehicle's historical cumulative MpG always exceeds 20MpG,
my pessimism would favor changing the oil by 5,000 miles.
The worse the cumulative MpG, the sooner you should change the oil.

Assume you are running 0W20 oil?

What state/climate do you live in?

Thanks for the reply. It gives some context.

This is sure to make some folks cringe, but whatever the dealer puts in it. I always run premium fuel and the first thing I do when I get in is disable the start stop garbage. She runs like a top.

I live in Northern Illinois and frequently drive to Northern Wisconsin. It’s been in 110 summer heat and -40 frozen tundra.

I understand that, but usually the larger particles are the ones that kill it. I always open filters on my vehicles. It is a habit. The one thing I find funny about this forum is how people with other generation of trucks comment about the newer ones, particulaly that theirs are so much better than the new ones. People seem to forget the problems that every generation truck has had. I have worked on GM Vehicles since the early 70's and every generation of truck have had their problems. It doesn't help any of us with newer vehicles, looking for information, to hear that all the time. That is why there are other sections for each generation of truck. This is the first forum that I have ever been a part of where this happens.

I see you've never been to tacomaworld or tundras.com. lol. Brutal over there...
