The Head Gasket Story Everyone's Heard Of
Search "Subaru head gasket" and you'll find one of the most well-documented engine problems in automotive history. Before 2012, Subaru's EJ25 2.5-liter boxer engine used a single-layer composite head gasket that tends to fail externally, and it typically fails at the back of the heads, an area you genuinely can't see without a mirror or a camera. Oil seeps out first, then sometimes coolant, and in the worst cases the two mix internally. The telltale signs are oil stains under the rear of the engine, a faint sweet coolant smell with no visible leak up front, and overheating on longer drives. This shows up most commonly around the 100,000 mile mark, and it's genuinely worth checking on any EJ25-equipped Subaru you own or are considering buying used.
FB25 Oil Consumption
Subaru redesigned the engine as the FB25 starting around 2011, which significantly improved the head gasket situation, but introduced a different problem: excessive oil consumption on certain 2011-2015 Foresters, Outbacks, Crosstreks, Imprezas, and Legacys. It was serious enough to become a class-action lawsuit covering roughly 650,000 vehicles. If your Subaru needs oil added noticeably before the next scheduled change, that's worth an actual consumption test rather than just topping it off and hoping.
WRX and BRZ: The Performance Side
Subaru's performance models have their own real history. WRX and STI models from roughly 2012 through 2017 were part of a class-action settlement over engine failure, and the BRZ, along with its Toyota-built twin, has more recently faced a lawsuit alleging oil starvation and bearing failures. If you drive either, checking oil level between changes is a genuinely worthwhile habit, not just a formality.
