Wayne Glover Uses Lucas in '85 Monte Carlo Dirt Racer

I'm writing to tell you what a good product you make on behalf of a friend of mine, who is too hard headed or something to write a letter. His name is Wayne Glover, and we both race dirt track cars. He runs in Hobby Stock and I run Mini Stock. Wayne’s car is a 1985 Monte Carlo with a cammed up 350 and I’ve got a 1988 Mustang with a 2.3 Lt. engine. In the first part of July Wayne decided his motor was a little weak and wanted to build a new and stronger one. So, we did and it turned out to be a good running motor. He told me he uses Lucas in his motors and I needed to also. I told him that I had always used STP and had had good luck with it and that’s what I was going to stick with. So, we built his motor and were painting it and got to the oil pan. I told him I had one that was already clean and he could have it. We put it on and everything looked god and fit like it was supposed too. He took it home and had it in his car, ready to race the next weekend. I was sitting in the stands the first time he raced with the new motor because my car wasn’t ready yet. Wayne ran the head race and came over afterwards to talk to me and said the car was running good and thought he was going to do well in the feature race. When the feature race started he had to drop low into turn four to avoid another car that had spun out. When he did, he hit some Road Grader Tires HARD! He made one more lap and left the track. I thought he had torn up something on the car. It was about an hour or so later when he came back to the stands and I asked him why he left the race. He told me his oil pressure dropped to 0, and after he got back to the pits, he figured out that the motor didn’t have any oil in it because the oil plug (for the pan I gave him) had come out. I felt bad because I didn’t check the oil plug, but he didn’t either. I asked him if he thought the motor was ruined and he smiled and said that he and his bother found and oil plug in his bothers tool box and four qt. of oil. They had started it up and it was holding 60lbs of oil pressure. He said the motor is probably ok and “I told you that Lucas is some good S%@&!” We were both happy and relieved. His motor has been running good every weekend since. I finally got my car ready and was able to race for the first time on Aug. 21st. I was nervous as I could be, but I think I'm really going to like dirt track racing. Before I raced I made sure my oil plug was tight and I had some Lucas in my motor. I’ve got 4 or 5 bottles of STP left, but I’ll find another use for them because of Wayne’s little mishap made a Lucas believer out of me.
