The $7,000 Mistake: Why This Engine Drinks Oil

In standard automotive engineering, an engine burning motor oil indicates catastrophic mechanical wear and imminent failure. For rotary engines, deliberate oil injection straight into the combustion chamber is a critical engineering specification required to keep internal seals alive. This technical breakdown explores the physics and mechanics of total-loss lubrication inside the Wankel rotary engine. We examine why geometric constraints isolate apex seals from conventional crankcase splash lubrication, how mechanical and electronic metering pumps dose oil based on throttle position, and what happens when owners attempt to stop internal oil consumption. The analysis details the real consequences of seal starvation, chatter wear, catastrophic tip failures, and multi-thousand-dollar rebuild costs, alongside the strict modern emissions regulations that ultimately sealed the fate of mass-produced rotary sports cars. This channel provides technical engineering analyses and mechanical breakdowns of unconventional automotive powertrains and historical vehicle designs.
