I will be having mi first IT race the month of July and I have a sentra b13 with a ga16de engine and the races are going to be about 30 minutes long and my question is Will I really need to have and oil cooler on an ambient temperature of 95 deg. in order to run W30 Red Line in my engine or you people think it will be kind of risky to run such a low weight oil at those temperatures with out an oil cooler?
