Kevin McDonald uses Lucas Liquid Polish on 1988 Jeep Wrangler

Detailing cars is a hobby for me, I enjoy the satisfaction that you get when that car just says "Wow". Ive used some good waxes and sealents in my past. I used to like Mothers wax and some meguirs. I resently found Lucas Liquid Polish on sale at PepBoys when i was picking up some Lucas fuel Treament and saw the polish, So iIbought it knowing that ive had such a success with the Treatment. So it has been sitting in my jeep, waiting for me to wash it. So to day I did, I wanted to see if it was better then Meguirs #26 hi tec yellow wax which is my fav, and the lucas produced a much better shine and was much easier to do. I now call this stuff "The polish of the Gods". Thanks Lucas

Jeffery Filiault uses 15/40 High TBN Truck Oil in 92 Kenworth T600 Cat Diesel

Since my first oil change on my 92 Kenworth after buying it used with 200,000 miles on it .The previous owner only used LUCAS OIL. It now has 650,000 miles and still no oil useage. I would not use anything but LUCAS. My racing miata now uses only 20 / 50 synthetic MOTOR OIL . The oil survived 2 hours of practice and a 4 hour induro and when drained still looked like new . This year I will put it to the ultimate test a 25 hour enduro at THUNDER HILL RACEWAY .This will be a brutal test wich I would not attemt with out LUCAS Oil Thanks....
