Mobil 1 full synthetic and motocraft filter from walmart. Stuff is cheap out there. U can get a jug of 5 quarts for less than 25.00. For the guys running twin turbos, anyone running valvoline vr1 racing oil? I run this on my turbo gsx due to its high zinc content that helps with turbo bearing longevity. Recomended by forced performance.
The zinc in VR1 will damage catalytic converters
