This is a complete Subaru engine reliability tier list covering every major boxer engine Subaru has built since 1989. I break down the FB25 oil consumption disaster that led to a class-action lawsuit, the EJ25 head gasket era, the EJ257 and FA20DIT ringland failure debate that splits the WRX/STI community down the middle, and the engine mechanics still call bulletproof decades later. 🔧 What you'll learn: Why "Subaru reliability" is actually a dozen different engines wearing the same badge Which Subaru engine has a documented class-action lawsuit behind it The real mechanism behind EJ257 and FA20DIT ringland failure (and why the forums can't agree on it) Why the EJ25 head gasket problem and the FB25 oil consumption problem are NOT the same issue Which modern turbo engine (FA24F) finally fixed the ringland weakness How to find your actual engine code in under 30 seconds What Subaru's most reliable engine ever built (EJ22) got right that later engines didn't If you're shopping for a used WRX, STI, Forester, Outback, or Crosstrek, this engine-by-engine breakdown will tell you exactly what's actually under the hood — because the model year alone won't. ⏱️ Timestamps below. 🔔 Subscribe for weekly Subaru reliability breakdowns, engine deep-dives, and buying guides every week. #SubaruBoxerEngine #WRX #STI #SubaruBoxerEngine #WRX #STI #SubaruReliability #EngineTierList #SubaruProblems #CarMaintenance #SubaruOwners #JDM
