I thought about this but couldn't resist. So, you're saying you'd be OK with buying a 35K car, having itSo you are telling everyone that cars that used road draft tubes instead of a PCV system didn't lose oil. Of course you used the word "appeared" so it's fair to say appearances can be deceiving. But anyway you are correct about one thing. In this day and age oil loss will soon be very nearly eliminated, of course getting rid of internal combustion engines altogether will be the primary reason for that.
appear to consume NO OIL for 8K miles, then suddenly start consuming it at a noticeable rate? This wouldn't concern you in the least? You'd chalk it up to the normal operation of an internal combustion engine, think nothing of it and not worry about it? I'm sure you can see by looking through this thread that there aren't many people in the world making this kind of investment who would agree with you. Every person experiencing this SHOULD be contacting Mazda and opening a case. It's the only way this is going to be addressed. There's goodness in numbers. I've been Googling this issue for a few months and now I'm starting to see evidence of class actions against Mazda for this. Are all of these people mistaken?
