Well lemme give you the history first.I have an 01 Galant LS with 135,000 miles on it.Just the other day, after getting off the highway in 85 degree weather, I noticed that when I came to a stop, my oil light would flicker.Now it only seems to do it after getting off the highway.If I go to a store or run errands in my area, its fine.So I took it to my mechanic and he replaced the oil switch.Everything was fine just driving around the neighborhood.The next day I went to work (back on the highway) and it wasnt that warm outside yet (no light came on).So when I came back home from work and got off the highway, the light started to flicker again.So now I know its not the oil switch.I took the car back to my mechanic and was told its the oil pump and that it would cost me $4,000 to drop the egnine and replace it.So is that it? Is that the only possible problem it can be and Im basically out of a car? I seriosuly cannot spend that kind of money on a car thats already a little beat up and has high mileage.I really dont know what to do.Do I drive it until the engine goes or are there other possible solutions?

Any help is appreciated!

try to see for any leak of oil in the engine.

$4000!!!!! WOW where you live?

try using a mitsubishi oil filter and synthetic oil (use 10w30, mobil 1 is good). It is a lil more expensive . had same problem after changing oil with cheap filter and bulk oil( oil that comes in 55gal drums ). Oil thins out as it heats up thats prob y it only happens off highway. I've also added stp oil treatment. the galant i have is a 2.4ltr 4cyl with 110,000 miles. hope this helps

Have a quality oil pressure gage installed and see what the pressure is. It only takes 5 to 10 PSI to keep the light off. If you live in a mild climate try a synthetic 10w30. If it is going to get cold before your next service go with a synthetic 5w30. It has the same thickness when hot, but is easer to pull out of the oil pan if it gets below 0.
