We’re very proud of both our engineering and customer service teams, so we offer the best warranty available in the alternative-fuels marketplace. Our warranty policy is straightforward and comprehensive — It gives you the confidence and peace of mind to save money by using waste vegetable oil (WVO), waste motor oil (WMO), algae or any other biofuel.

Our industry-leading reputation is based on quality products supported by exceptional customer service


We don’t stand behind our products…. Instead, we stand with our products, since our business success depends on supplying you with reliable, mission-critical fuel systems and components for your daily life even when you’re on the road, far from home.

As with any type of equipment, the warranty depends on the specific part. Here are the general manufacturer warranties for major parts:

  • Centrifuge castings: Lifetime warranty
  • Heaters & AC drives: 1-year warranty
  • Motors: 1-year warranty

Parts such as seals, bearings and clamps are warrantied for one year from the date of purchase. Please note that warranties do not apply to any parts or products which have been abused, misused, or damaged following incorrect installation or any use contrary to the instructions by the manufacturer.

Return Policy: 30-Day Money-Back Guarantee

We value your satisfaction above all. If you determine that any of our products doesn’t function properly, simply contact us immediately so that we can provide troubleshooting and additional support or replacement. If you’re still not satisfied, we’ll refund your money within 30 days after the date of purchase. Shipping is not refundable.
