I am happy to say that I have tried Pow-R 365 and have experienced positive results. I ran mileage tests in two of my trucks (Ford F450 & F550) and saw noticeable improvement quickly. In just two weeks, I had an 11% increase in fuel mpg and more power. It’s great to find a product that works!

I have been a Penray customer for about two years now and I have been very happy with the product quality. One of the main reasons that I switched to Penray was their Protection Plan. That’s a great program to offer your customers That really showed me that they stand behind their product. If you haven’t been happy with your additive company definitely give Penray a try!

Our fleet customers have been able to reduce their inventory of coolants to ONE, reducing the SKUs and time to buy/bid multiple types and keep the right one on the shelf. Now they add proper testing at PM time, add Pencool® 3000 and have one coolant to stock = simple and cost-effective decision. Our focus with Penray has been on helping fleets streamline their coolant requirements to eliminate problems in mixing coolants.
