Had an odd experience while having the car serviced at an Indy (last service 2024). There's a post here.
I have had the 996 from 73000 miles 4 years ago and it's now on 103k (ish). I have always used the standard Porsche recommended oil, Mobil 1 FS 0W40.
My experience with this oil has always been fine, virtually no oil burnt between services (8k miles approx), from some advice here I used my oil pressure to dictate when the car was warmed up fully, the way it worked was, once warm, the revs pretty much matched the oil pressure, so 3000 revs 3 bar etc. On tickover it was always about 1 bar.
Following my service I drove home and noticed very odd oil pressure, it was way higher than I am used to, so i took the car back and asked the indy what oil they had used, for the first time (for an Indy) they had changed the standard 996 oil to Mobil 1 5W50, I asked them to change it and they said they had, driving home the oil pressure was still the same so I guess they just lied.
After some 7 months driving the car like this, it is very odd, oil pressure even when warm is super high, e.g. 2000 revs is just a tad below 4 bar, tickover is a tad above 2 and anything above 2 is between 4 and 5 bar/off the scale.
What do you guys think, should I go back to Mobil 1 FS 0W40 or perhaps stay with the higher viscosity but change to the hartech recommended Millers Nanodrive CFS 10w50 NT?
