Is it normal for a 2002 sl2 with 120,000 miles go through a quart of oil a month?
I don't see any leaks car seems to run fine but I add about a quart a month. It does have
a bad ABS sensor that I disconnected.
Not normal, but if you don't see any leaks, your probably burning it. Worn Valve seals or piston rings are usually the culprit. As long as you keep adding and not allowing it to get low, your good. As far as disconnecting the ABS sensor, you do know by doing that by doing that your car no longer has ABS activated? So in a panic situation be sure to pump the brakes. But I'd recommend getting that reconnected and repaired.
Look for blue smoke out the tailpipe. That's a sure sign of oil burning. If it only smokes at idle it's worn valve guide seals. If it smokes while driving it's worn rings. HTH. -Jim
