Why is it that both of my SSEis have 20psi of oil pressure at 600-700RPM at HOT idle in drive and 25psi in neutral (800 or so RPM), yet have well over 40 at 1500 RPM cruising. I tested the car at 55ish PSI with a mechanical gauge about 2 months ago. but that was cold startup which it shows 60ish on the gauge at 600RPM.
I dont get it.
Who else has this low of oil pressure on their 92-99 SSEi?
According to the manual anything between the 1/4 and 3/4 tank is normal, however my 2000 SSEi never really got a 1/4 inch past the 40PSI mark at hot idle.
Here are the pics.
I can only guess this is normal.
Keep in mind the marker NEVER drops below 40 unless the cars have been run hard and on a hot day (86* today) I'm close to switching to a slightly thicker oil for the summer since the motor never got hot in the winter, therefore oil pressure was nowhere near as low as it is now. I know the car is designed for 10w30 but I may just go one step thicker...
