I am a little upset right now.My brother and I run at the local dragstrip.I have a corvette with only 425 HP, he runs a S-10 with about 700 HP.Saturday night on his last pass the oil pressure went to zero. Today we pulled it apart and could not find any brass on the berrings.The thing that pissed me off is he was running Lucas and didnt tell me about the product.I will be a new Lucas consumer. The proff is in the pudding.You have a new customer. Thanks
