Bought new 1977 VW Rabbit, valve guides bad at 30,000 miles..it was an embarrassing smoker.
I also had a bought new 1977 VW Rabbit with bad valve guides from day 1. On trips it used more oil than gas. Dealer said that was normal. They said that using 1 quart in 350 or less miles was "normal"on a new vehicleBought new 1977 VW Rabbit, valve guides bad at 30,000 miles..it was an embarrassing smoker.
An engine can burn oil and leak oil at the same time.I think we need to first define what constitutes an oil burner.
An engine that is proven to have no external leaks is a starting point. Then, one that doesn't lose more than X amount of oil in Y amount of engine hours? What else?
Well it depends on how we define oil burner - per your question, but there independant measures. Of course the issue is measuring which loss comes from which problem?They sure can leak and burn at the same time, but if burn rate is very low while total oil loss is considerable then is it an oil burner?
