The gas trucks use basically a day / mileage countdown timer to determine oil life. Diesel trucks use the "intelligent" oil minder which is based on many things including idling vs highway time, speed, engine oil temps, miles / days, number of regenerations, etc. Since this oil life percent remaining might "change" if you are suddenly doing a lot of highway driving or suddenly idling a lot...Ford simply doesn't display it. You'll still get the warning when its time to change...

 

 

I've never seen the "soon" on the 2017+ models. Just the "required."

 

Mine has roughly a 10k oil life according to forscan. I change around 7500 though.

The truck is so tall, I can fit a 5 gallon gas can direftly below the drain clock to catch the dirty oil. Oil changes couldn't be much easier.

 

 

The Ford Pass app shows oil life left. I'm not sure if it works with the lariat but should work with any truck running sync 3.

 

The fordpass app is hit or miss on if it works. I got it to run once in October of 2017. Have never been able to get it to report out since.

 

My 2019 PSD platinum shows oil life under the Advanced options on the information display. You have to be stopped to enter that menu but it does show the % of oil life left. It also has the oil life percentage on the app on my phone.

 

I watch DIST_UNTIL_OIL PID on Forscan

 

Weird. I've never had an issue with it. Always shows correct fuel amount so I'm assuming that the oil life percentage is correct too.

 

Same - it's a nice feature.

 

Your truck Emails you? Whaaaaat?

My odometer is all I need for oil changes...I just reset the reminder whenever it shows up and forget about it

 

Where on the Ford Pass app are you guys seeing the oil life? I don't even see where it would be an option.
