There has been some speculation here about IOLM/OLM's so I thought I would collect some data. This is from a 2013 F150. I have always thought that Ford's IOLM was a 10000 mile / 6 month counter, and once I saw that this oil change would be 99% highway miles and less than 6 months I started keeping track of the IOLM and mileage. Here's the data:
miles.....IOLM........interval......IOLM change
30388....37%
31037....30%.....649 miles..........7%
32001....21%.....964 miles..........9%
32119....19%.....118 miles..........2%
32828....12%.....709 miles..........7%
33071....10%.....243 miles..........2%
33191.....9%......120 miles..........1%
So even though I didn't catch the IOLM just as it changed each time, it's easy to see that for every 100 miles, the counter reduces by 1%.
Thoughts?
(I noticed the trend earlier on in the OCI but didn't keep track until later)
