It has been a year since my last oil change. I am still at 80%of oil life. Nevertheless I took my car in to my local Acura, that finally got a trained NSX Tech. I decided to change the oil, duel motor (trans fluid), the Transmission and rear end (trans fluid, and gear oil). I live in the hills of Santa Barbara and drive short distances so the car does not get hot enough. I am taking an oil sample and sending it in for analysis. I will report out the results.
