Quaker State Ultimate Durability 5W-40 synthetic oil was used to fill the crankcase and the Fram HP4 high performance/hi-flow oil filter. Since the motor was broken in on the dyno, we didn't hesitate to use synthetic lube. The Fram HP4 will easily flow more oil than regular oil filters-notice the larger flow holes in the HP Fram filter. The Q oil is said to offer unsurpassed protection against friction as temperatures increase.
