My car burns oil right now, quite a bit actually, like a quart every 500 miles or so in the city (lots and lots of stop & go, no non-stop stretches longer than a mile usually, no trip during school longer than 3 miles, lots of engine braking) because of worn valve seals. I have heard lots about putting STP Oil Treatment in an engine to cure this, but want to make sure that I wont hurt the engine first.

PLEASE DONT TELL ME TO GET THIS FIXED. I KNOW IT NEEDS IT, BUT I HAVE OTHER THINGS TO DO AND TO GET FIXED FIRST.

Like:

• New timing chain: current one 146k or so, replacement costs $~500 tax included.
• Entirely new exhaust system. Delivered phonebooks rurally and ripped off both mufflers, and screwed up the exhaust manifold. Needs everything from the manifold back to the rear bumper. Has reduced ground clearance from 5" to about 1.5" because of straight piping. $1000 to fix.
• A tune up. $120 or so.
• God only knows what else. Lets hope its cheap.
