I would like to say that your product is excellent.

Smoother idling, improved fuel mileage and improved power. A person would have to use this product to appreciate it and see the difference in performance. One happy driver,

-Arthur M., Deer Lake, Cdn

I became an owner operator in 2001 and have been using your product faithfully year round.

I haul fuel for a company based in Edmonton Alberta Canada and I travel to various destinations throughout northern British Columbia and the Northwest Territories, in temperatures ranging from 30 to -50 below 0. I have never experienced a fuel system problem of any kind. I have also done a comparison in my fuel mileage and on the performance of my truck and found that using Howes makes all the difference. Yours truly,

-Paul C., Edmonton, Canada
