Alright so I just installed an o/r h pipe and tuned my car after driving about 55 miles the engine oil level low light came on so i added some oil and light was still on so then I flashed my stock tune, started up the car light was off, then I flashed my 91 tune back on and it was all good. Next day I get an oil change and I drove the car for about 20 miles, parked it, then went to go start it again and engine oil level low light came back on, I highly doubt my car burned that much oil in only a 20 mile drive, any idea what the problem can be?
