It is well known at this point that the second generation Toyota GR86 and Subaru BRZ suffer from low oil pressure during right hand turns, while driving on the track. Several members of the 86 community have been testing and hunting for a solution, or mitigation, for several months now. This past weekend, I took to Chuckwalla Valley Raceway to perform some testing of my own and see just how bad the oil pressure drops were on my own 2022 Toyota GR86. In addition to getting baseline oil pressure data, I was able to perform a couple of different tests. The first test was seeing how oil temperature affects the oil pressure and the results were surprising! The second test was seeing how an additional 1/2 quart of oil added to the engine affected oil pressure. In the end, we did still observe low oil pressure, but were able to improve things a little bit by keeping oil temperature down and slightly over filling the oil.
