Hey Lucas Oil,

I just wanted to say thank you. Ya'll have the BEST product on the market. I will use no other diesel fuel supplement for my 1997 Ford F250 power stroke diesel!!! I have used it several times in my truck (once every few thousand mile) and it consistently boosts my fuel economy. Last week I used it and it improved my mileage from 14.4 mpg to 17.7 mpg. After punching the numbers I found that it really did more than pay for itself!!!

Thanks again,

Kevin B. Price
