Our passion for the superior characteristics of synthetic oil were first realized while performing duties as a aircraft maintenance specialist in the US Air Force. That passion has transitioned into a winning formula for mechanical reliability in heavy duty applications. It's a real simple 3 prong approach: Start out with premium lubricants, use premium primary and secondary "bypass" filtration, conduct proper scheduled oil analysis testing and understand the reports. This will give you the ultimate confidence of knowing that you've done the best you can.
