Oil pressure drop in the FA24 engine on track
Severity 2/3 · CostlyUS owners have measured, on track, oil pressure drops that can exceed 50% in right-hand corners, especially on gradients, on BRZ/GR86 cars with the FA24 engine (sample of three cars). One owner says they know three people whose engine failed on track and links these failures to this phenomenon; this is a testimony, not a statistic. The risk is mainly in sporty or track use.
