Tom Mayersky uses Lucas Heavy Duty Oil Stabilizer for Ford Ranger

Dear Sir,

I got introduced to your product at the Hooters ProCup race as I help in the pits. Plus, I like the Lucas Oil display at our local Parts America store in Lancaster, PA.

I had a 1989 Ford Ranger that had over 100,000 miles on it. I used Lucas Oil faithfully in it. The truck ran great and the miles kept coming. I know have a 2001 Ford Ranger and every 3,000 miles I have Lucas Oil Stabilizer added to the new oil. I believe in you product. The cost at my store is $6.95 and its worth it.

I hope to put over 148,000 miles on this Ranger. With running kids to swim practice, and me coaching high school football and scouting appointments, I put over 15,000 miles a year on my truck. My truck has over 20,000 miles and its not quite a year old.

I have confidence in my truck with Lucas Oil everyday when I leave for school (I am a PE and health teacher for grades 5 and 6). Players that drive to school with the late model cars and trucks I tell them about Lucas Oil.

A Loyal Customer
