Superior Protection and less breakdown. Go further between oil changes, and save money on services and fuel consumption. We've tested it for year in our own vehicles. It cleans up your engine, so we used Premium Oil Filters. We went from 3000 mile intervals, to 5000 mile intervals. At 5000 mile intervals, we would rotate the tires and grease the vehicle. So we did all standard services at once. Saves us from rotating tires, every second oil change also. We have converted a lot of our customers to do the same. Save some $$$$, if your paying for your services.
