What Engine hours do we think is good for an oil change interval?

[PMT133]

Going by the OLM in my truck, it's about 200 hours to change.

At work we have a lot of trucks that idle a ton so they're accumulating 2-400 hours of run time with less than 1000 miles on the interval in some cases. Usually equals every 3-4 months they get serviced. They do random sampling for oil analysis too and that normally agrees with the intervals used.

So after all of this I don't think we still have a clear answer on How many Hours, And How many gallons of fuel burned would be the right number if met before the 4000 miles/10 Months, Just a few opinions on what some people do. Is there any testing data that we can use to find a good number?

Why the bold? There's no need to shout.

Cool, I drive a honda

lol. ok ....

If the car records the hours sure. The average car does not have an hour meter, that's usually a truck thing, and we want a simple reading not going through obdii to get it.

no recording of hours but you can see how long it was recording coolant temp to see how many hours you drove that trip etc.

I'll just whip out the scan tool and add up the minutes of coolant logging after every drive
