Take a look at your Trip odometer, you might have two (2).
If it has an elapsed time feature you are good. Just convert to hours rather than miles. If your normal service mileage from the OEM is 7500 miles, that would equate to 150 hours, based on 50 MPH as a highway average/normal service. Run your current fill to 150 hrs, do a UOA and see where you are. add or subtract hrs from there.
Every combustion engine's OCI on the planet is calculated based on Hours of running time EXCEPT cars & light trucks. Makes no sense to me. I run a consistent Avg of 34 to 36 MPH, which equates to 5100 to 5400 miles at 150 hrs on the elapsed time on trip B So I change it my first day off after I hit 150 hours. I don't care what the mileage is nor the calender time as long as does not exceed 1 year or 7500 miles.
I ran my last interval 550 hours. 150 is very short.
Warranty, just don't need the hassle.
