I was wondering if anyone else is losing oil? After an oil change my car will go down about 1/2 quart of oil in about 500 miles , then it will even out at about 1/2 quart every 1,000 miles. Could it be my rings going or what? My engine is a 93' 2.5 w/ 100,000 miles on it. That would be pretty early for the rings to be going, right??????????

my cars' got 115k...I had to change my front valve cover gasket right around 100k and now my car is leaking because I have to change the rear valve cover...however my car doesn't leak nearly as much oil as yours....another thing that makes our cars leak is the "oil pressure switch" it's located just above the oil filter....check to see if its' coming from there....dunno where else it could b from...

oil loss on our motors is typical. it means the lifters are working properly. I dont think that much leakagee is typical though,

Hey Blademx00 did you ever find the oil problem as mine just started the same thing and there is no leaks around the engine and I dont see any smoke out the exhaust pipe. Thanks Speed Demon

dig it,

The mazda 2.5 L motors have always had a leaking problem from the rear (closest to the driver) valve cover. Simply replace it. I use mobil one 0w30 becuse I live in a cold winter and hot summer place, and I loose about half a quart per oil change, (after replaceing all leaking gaskets) and I have about 110k miles.
