Lucas Oil's Blue 50-Wt Oil saves another motor


We’d like to give special mention and thanks to Lucas Oil for their new Blue 50 Oil. This product was a quite literally a motor saver during this race. During one of Mike’s qualifying runs, the lifter broke on the starting line and parts of the lifter lodged in the oil pump and sheared the pump. Mike made a full pass (6.25/232) with no oil pressure. When crew chief, Kirk Kuhns, reluctantly took a look at the damage, it was like nothing he’d ever seen in his 30+ years of experience in drag racing. There was only minor bearing damage. He couldn’t believe the we didn’t window the block. If not for the Blue 50 Oil, we’d be spending a lot of time and money fixing major motor damage. Thanks Lucas!!!
