Oil Life gauge
There may already be a topic on this but I'm working in an area in WV with horrible wi fi and doing a search sucks. I've gone over the 5 thousand mile mark on my oil change (full synthetic) but my truck is showing I'm still around the 40% mark for oil life. Anyone here know how accurate this gauge is on our trucks?

I don't trust that monitor. Mine didn't come on the first time until 15k, no way I would wait that long. I ignore it and change with Mobil1 no more than 7500 miles, and reset the monitor after I do it.

Based on the percentage mine shouldn't go 15,000 but you never know.

Is this km?
If so that is what it's programmed for as a maximum. If it's miles something is wrong!

Algorithm based on what the truck is doing. Mine went off around 10000 km or so, or 6000 miles. For now I follow it's life cycles. I might do like my old truck and analyze the oil and then determine what change to go with. I run my old gmc off amsoils severe service interval in the signature series which is 15000 miles. At 150 some thousand miles it's clean inside and runs fine... but it gets used like a big truck in a lot of ways. That and my Ford has no oil dilution concerns so I don't worry about that either.

Face palm all you want. These trucks do not use oil quality sensors and have no actual idea of what the oil quality is.
I spend a lot of time in dusty/dirty environments. Plenty of time my black dash looks tan from all the chaff/dirt/dust during planting season and then again during harvest. A bunch of these hours are also spent at low RPM. I would assume that Fords algorithm accounts for the low RPM and thinks oil change intervals should be even greater.
An oil change every 5k is the cheapest part of owning a truck.
