Wanted to see what others are doing for oil on their track pack cars. For my first oil change I went with the 5W-50 Motorcrafter per the oil cap. I know I am giving up gas mileage using this oil. I don't plan on tracking car for a long time, car is my DD right now. I was thinking of using a 0W-30 or 5W-30 for a bit more protection over 5W-20.
What are you using?
