My oil pressure light has come on. The light came on about 4000 miles ago and we found that the oil pump and screen were "gunked up". The dealer suggested we change the sending switch as well and we did. I am confused as to why this situation has occurred because I change my oil every 3000 to 5000 miles.
Well we made the repair and everything was fine. Today I was running errands and when I came out of a store to start my car there was my oil pressure light on again. The engine sounded normal and wasn't making any rapping or clacking noise. I checked the oil level and found it to be fine, so I drove it home and parked it. No problems occurred on the ride home except that oil pressure light staying on. I let the car sit for several hours and then started again. The oil; pressure light is still on. The engine still sounds just fine. What could be causing this reoccurring problem? Has this been a problem for other Aveo's?

The first thing I would do is check the actual oil pressure and see if its within spec?Then I would go from there no on going oil pressure issues that I know of. What brand of oil do you use?

Checking the actual oil pressure is my next step, and then replacing the new oil sending switch is next if it shows to spec. I'm hoping it's just a bad replacement that was installed.

I use 5-30 Luk oil. The service station brand where I get all my work done.

Yes I have owned the car since new. It's been a great little car. I was hoping to keep for another 50,000 miles. But if this is going to be a recurring problem, I guess not.

Luk oil took Getty Oil over. I have been using the service station oil since the car was new. The same guy has been working on my car since I bought it. I'm usually in the shop when work is done on my car so I know it is getting done.

The only other thing with the car is that I put in about a gallon of coolant in the system per year. I see no leaks and I don't detect any signs of it burning. I did have a rear main seal oil leak which was repaired prior to the oil pressure problem. But other than the period of time when the oil leak occurred I have not had to top up the oil.

Thanks for your follow up.
