![Question](https://rennlist.com/forums/images/icons/icon5.gif)
I know the oil issue has been hashed around a lot and I have read numerous posts. Given that my new (to me car) already needs a new transmission due to a bad PPI , I am now paranoid about everthing.
Issue: Oil pressure gauge appears to read about 0.8 bars low.
Oil: Mobil 1 0W40 - changed last week. (I will likely go to a 5W50 next time)
Car: 1999 996 C4 - 6 speed - new to me in the last couple of weeks.
Engine: Remanufactured 3.4L with a total of 25K miles on it.
Cold start up - 4.0 to 4.2 bars - never higher
Hot idle - 0.8 to 1.1 bars idling at about 600 rpm - engine temp showing ~190F (no evidence of oil pressure warning light)
Hot @ 3K rpm - 3.0 to 3.1 bar
Does this sound like the sender more than anything? Given that it appears to be consistently off by about 0.6 bar....
Many thanks
