To be clear, I'm not arguing against having dipsticks, but that doesn't even make sense. Oil pressure has no correlation to oil level until the oil level drops significantly. How do you measure oil level using oil pressure? The sensor in my Audi doesn't go off oil pressure. The car needs to be on a level surface and the engine has to be off for a certain amount of time before the oil level will show on the display. And it's quite accurate under those conditions. If the sensor says I'm 1/2 quart low and I add 1/2 quart, it's full when I check it again. I added an aftermarket dipstick for my own peace of mind though, because as already mentioned, sensors fail.
All the reads are always amusing to dis BOIRD. All the fancy electronics, and the calculated PSI Oil Pressure. Wat I do is simple, guess Army trained: I see the Oil PSI (make a mental note), the idiot light, the gauge telling me how much Oil Life is left, etc. I just do the Military thing. Every 2-4 weeks do a lil PMCS on truck: Pop hood when engine cold: Check Oil Level, Check Antifreeze level in reservoir, play peek a boo at brake fluid reservoir, look at air pressures on Evic display ref tires but I use a digital gauge to fill ne way, and once in a while peek at the engine and under truck for any tell tale drips. YUP, Military (Army Trained). Found a lil PMCS helps and it helps to have a MX schedule you follow: Like rotate tires every 5,000 miles, change oil every 5,000. Just wat I do and works.
CAVEAT: I do hate the not having a dipstick for the HP trans, but alas, it is what it is.
ADDED: For the Non Military: PMCS Preventive Maintenance Checks and Services: (ie., what is "required" before U operate any equipment).
TO THE OP: I guess off topic a bit, but WTH. And for me, I will keep my old reliable Hemi till tires fall off, do not want a 6 Cylinder truck, if I did, I would have bought instead of Hemi, but again, that is just me, all above IMHO.....
