Testing

The graph below shows the friction coefficients of two of the top selling Heavy-Duty diesel oils with and without CamGuard HD Diesel. The friction coefficient serves as an excellent indicator of fuel economy and is a primary consideration of automotive oils. In Heavy-Duty diesel oil testing, fuel economy is not measured or even considered. The tests were performed at an independent lab utilizing an industry standard method (FALEX Block on Ring tribometer). The test procedure consists of heating the oils to 200 degrees F, then slowly raising the contact pressure and measuring the coefficient of friction.

The red bars show the friction coefficients for each untreated oils. The blue bars show the friction coefficient with 5% CamGuard HD Diesel. This remarkable reduction in the friction offers substantial benefits in terms of boosting fuel economy and reducing oil temperatures over untreated commercial Heavy-Duty oils.

The photos below are pistons removed from two different Lycoming IO-540 aircraft engines. The piston on the left is from our FAA certification engine using CamGuard for 500 hours. The certification test was in an aerobatic aircraft that utilized very high-power settings resulting in extremely high temperatures. The piston on the right was taken from a non-aerobatic aircraft engine that was flown at typical cruise power settings, without CamGuard, for 500 hours. The difference in deposits is striking. Because of this extraordinary experience, we expanded the CamGuard family to include other applications.
