Had a Hyundai Elantra on Amsoil Synthetic and changed the oil like 18 times in 136k. Used like a quart every 5k like it did from day one.

Modern gasoline engines burn really clean, so that the 3000 mile oil change is really a joke. Gotta keep the oil change places busy I guess.

If you want to do something, get a sample of the engine oil and get it analyzed. Then base your changes on that. Save you a ton of money and you can track the condition of the engine.
