I owned three rotary engines many, many years ago. I even put an aftermarket turbo on one of them. The truth is that they cured its problems (none of which I had) a long time ago, but by then it’s reputation was ruined. And they actually burned some oil on purpose. They had to inject a small amount of oil into the combustion chamber to lubricate the seals.
But mine really did not burn much. In fact, there are MANY reports of BMWs, especially the V8s burning oil. A friend of mine just sold his X5 50 after his dealer told him that a quart every 800 miles was within BMWs “normal” range. |
Yeah, BMW inline 6's are usually more durable/reliable in the ling run. Despite all the changes made to the N63 V8 over the years, they still seem too problematic to own long-term.
