im not talking about car being hot thats completely normal. its hot and i get the reduced power message thats the problem.
It's very common, even in traffic oil temps creep up. The heat exchanger in the lower portion of the bumper blocks a small portion of the factory oil cooler, but there's really no other location for it.
For aggressive drivers or extended sessions. you would definitely benefit from a larger oil cooler: either the M24 or custom.
