AJ has seen the results first hand and is now dealer for Admax at BGR.We never really had oil issues with other brands until we started running the blower and alcohol which is the worst environment.We were told horror stories about bearing life in that application.Mike Kosky of Top/Alcohol dragster fame, who helps us told us we would be changing bearing every few runs and other oil related issues.Maybe we can get AJ to post some pictures of the bearing.Again thanks Bob Petty and Admax Oil.
