Dear Sirs,

This letter is to tell you how pleased I am with your oil additive.

We show registered paint horses throughout the West and really depend on our trucks, mostly Ford Powerstroke diesels.

We have used synthetic oil in our trucks, but didn't see an appreciable difference in fuel mileage.

After using your oil additive we found that the engine temps dropped on long climbs and our miles per gallon increased by 10% to 13%.

We also seem to have more power, especially when pulling heavy loads.

Thanks for such a great product.

Tim D.
