Question about 1991 Mitsubishi Eclipse
When I'm driving my car where should the needle be should it be on the high side or the low side I'm not sure about this. On my gauge I have an L on the left in the middle is an oil can and to the right is an H. I dont want the car the oil pressure too hot. I just need to know that I'm reading the gauge right.
Any where from a quarter to half way is fine. After this the oil presser is getting to high. be sure you run 10-30 in the winter and do a oil change in spring time to 10-40 . oil will thin in hot temp. thus using a thicker oil like 10-40 in the summer will help keep oil presser down .

SOURCE: oil pressure gauge reads past 80
now unless there is a very loud knocking of the motor which would mean that the engine's top end was not getting any oil I would say that your oil guage is sprung and needs replacing. a high pressure rating would indicate a restriction in the oil flow pasdt the sending unit or a plugged oil filter. if the filter were plugged you would know it because your enging would run tight in no time at all. replace the guage itself... please rate this........thanks

SOURCE: Oil gauge high
The pressure will depend on the temp. of the engine, and the RPM's. Just make sure you have the correct amount of oil in your engine. I wouldn't worry about the pressure until it gets too low, then your almost out of oil. Mine currently stays above mid-point as well.

Hello mb4494: My name is Roger and I will help you. If by changing the oil pressure sending unit the problem did not change. I would perform a oil pressure test. This is done by removing the oil pressure sensor and inserting a oil pressure gauge. This can be done by yourself or by a repair shop. This needs to be done on a cold engine. Start the engine and observe the oil pressure cold.as the engine warms up observe the pressure. The pressure will drop off as the engine warms up.Should the oil pressure drop below 10 to 12 PSI. then you have internal engine trouble. More then likely a bearing problem. Try dropping the truck into gear and see what the pressure drops off to. Again if the pressure drops below 10 to 12 PSI. you have a problem. I would also check to make sure you have the correct oil switch. a truck with a oil light uses a oil pressure switch. with a gauge you would use a oil pressure sending unit. Sorry for the long reply but want to make sure you check the pressure correctly. Please rate the quality of the answer as this is how we know the answer was correct. Thank You for using Fix Ya. Roger
