I may or may not have pushed close to 15,000 on my 01. Pretty sure that water would have been a better lubricant when I finally changed it.5k on all my Toyotas.
I did go almost 10k on my 02 Tundra once and I’ll never do that again. That oil was ugly.
Self changing oil is the best oil in my opinion.My truck leaks/burns oil so bad that theres absolutely no need to change it. I just add a new quart every time I get gas, equivalent to an oil change every 1k miles
Napa brand is ValveolineI have also used Mobil one and other different synthetics. Use what you want, I am not here to tell you not to nor did I tell anyone they should/shouldnt use anything.
I just stated that I have had good luck using NAPA branded oil.
Perhaps on new rigs but many of the older ones are just mileage.Most are algorithm based where driving conditions are monitored and the change interval varies depending on use.
Yes, I was thinking/talking primarily newer vehicles. By '15 Dodges were algorithm. Don't know when they started but my '15 would obviously vary on usage.Perhaps on new rigs but many of the older ones are just mileage.
This is correct on modern vehicles.Most are using algorithms, sensors, and software where the driving conditions are monitored and the change interval varies depending on use.

I second this! Coming from a professional engineerI change my diesel truck every 5000 miles. The book says every 7000. The math is just easier.
A number of discussions I had with chem. engineers over the years, said the oil is stable but the additives have a shorter life span by time and miles. Oil is cheaper than an engine.
I have a cobalt and a Sierra - I change the oil when it hits about 25% of oil life. Give it a take a little bit. The 6.2 is starting to use a little at 170kI have an 03 Chevy Tahoe that I have only changed oil based on the oil life monitor as that is what the manual says. 350,000 miles and going strong with no engine issues.
