Un related questions:
My 2018 has a button where I can see the useful life of the oil.
1.What is the useful oil life point where the oil should be changed?
The windshield sticker mileage and date of oil change (sticker from the dealer) doesn't seem to match,
as my reason for asking this.
------------------------------
2.What is the approximate oil temp that I should have? (another button that can be pushed)
3.What is the approximate oil pressure that I should see from the 3.6 engine with 11,000 miles?
Thanks in advance for the info.
I am a self proclaimed expert in....
If decent oil - QS, PZ, M1, etc change it when it says 0 life or reaches 10k since last change. I get a bit over 8500 miles on mine. There's nothing that actually analyses oil condition. It's based on stuff like speed, idle, temperature. Oil life counter will go down less if you drive 500 miles at 70 MPH, than if you drive 500 miles stop and go. As far as the sticker, it probably says much less. Manual says exactly what I did. Oil change places - dealer or otherwise - like to see you sooner for profit motive.
Those engines typically hover around 200 degrees for "normal" driving highway or around town. Coolant will be close to oil temp, and transmission will usually be around 180 or so during 70 or so weather - all again as long as you are not doing anything stressful. Transmission may be lower at highway speeds.
#3 ... Oil pressure. I lived through learning that FCA - Dodge - Chrysler - doesn't give a crap about owners. Brand new car with a bad oil pump right from the factory. On a 3.6, when cold, oil pressure will be around 80-99 PSI when accelerating. So over about 2500 rpm when cold, you'll see the oil pressure peg out at 99 psi, and then drop to like 60. Two stage oil pump.
When warm - over 155 degrees oil temp - you will see the "sudden drop" rpm coming down where if you exceed that, oil pressure will drop about 30 psi. When fully warmed up, during cinstant speed driving, where you are around 1500 RPM or so, the oil pressure will probably hover around 40 psi. Put it to it, and you'll see the pressure rise, and then drop 30 psi or so at about 4000 rpm.
Simple answer... Fully warmed, normal driving... Around 40 psi. If it never goes below 60 psi, then you have an oil pump issue like mine, but it will throw a CEL also.
