Most mpg claims are pure baloney. You know it, and so do we. That’s why Valvoline, a leading name in engine lubricants, is teaming up with tiwi, an innovator in the development of driver-monitoring and driver-mentoring systems – offering the first and only program proven to deliver better fleet fuel mileage, backed with an exclusive limited Fuel Proof Guarantee.

Up To 4% Better Fuel Economy. Guaranteed.

Our products combine to improve engine and driver performance, resulting in a fuel economy increase of up to 4%. We know this because we have proven results from independent facilities that have run our products using the only EPA SmartWay^SM recognized fuel test protocol – SAE J1321.

We also have real-world proof from fleet use. And the Fuel Proof Guarantee is the subject of numerous articles in trade publications.

Still skeptical? We understand. That’s why our products come with an unconditional limited guarantee. If, for any reason, you do not receive fuel economy gains after the 120-day customer demonstration, we will remove our equipment and refund the incremental cost of the demonstration.
