About 2 months ago I noticed that my oil pressure gauge was only reading right below 30 (which is normal). But under accleration it wouldn't go past 60. I immediately took it into the dealer and got and oil change thinking that I was low on oil. After doing an oil change everything was fine and the pressure was good. Now after 2 months and about 2200 miles it's doin it again. At idle it sits right below 30psi however under hard acceleration it doesn't go above 60 (or even to 60).

If there was a problem with the oil pressure wouldn't the oil light come on? Would it come on for the pressure or oil level? Would the CEL come on if there was a problem? I'm going to the dealer today to have an oil changed and making an appoitment to have the check the pressure sending unit.

Anyone else have this problem?
