Subaru models equipped with FB20, FB25, and certain EJ25 engines experienced widespread excessive oil consumption. Many owners reported burning up to 1 quart every 1,000 miles, leading to low‑oil conditions, stalling risk, and premature engine wear. This defect became one of Subaru’s most litigated engine issues.
