So while my A6 is in the body shop for some work, the rental agency was kind enough to give me a 2012 T&C for 4 days. It has the 3.6 Pentastar with the 62TE 6 speed auto.
While playing with the DIC in the cluster, I found that it has actual gauges for oil temp and pressure. In the 30 mile highway drive to and from work, I've found that at 1750 rpm the pressure is a steady 40 psi and the temp seems to hold right at 170 degrees. This is with what I assume to be conventional 5W-30, because that is what's printed right on the oil filler cap.
Any opinions on whether 40 psi is low, high, or correct? I know that we like to debate the move to 5W-20 in some engines, and I wonder if this particular engine could live its life on 5W-20 and still see adequate oil pressure at this temp.
I ask because in my Audi I have an oil temp gauge, but no pressure one. I typically see temps of 200-210 degrees all year round, but I also have two turbos. I've never put a pressure gauge on my car, so I don't know what pressure it runs at with the 0/5W-40 I run in it.
Is an oil temp of 170 low? Would a good synthetic 0/5W-20 be ample protection at that temp? Would it be enough if the engine ran at 200 or 210 degrees, or would the 5W-30 then be necessary?
P.S. - The 62TE is one busy and clunky transmission. In normal in town driving at moderate acceleration, it actually shift from 2nd to 5th gear in 2 seconds. It really holds 1st gear and then makes every effort to get to the highest gear possible for economy reasons, and that is with the Economy button turned off. When in Economy mode, it will upshift to 6th every chance it gets and lug @ 1100 rpm in town, and will not down shift with gently pedal pressure. When enough pressure is applied to force it to downshift, it rockets into 3rd gear and really takes off. There is no inbetween. I'm really thinking twice about buying one of these next summer, just because of the trans performance issues.
