Oil formulations are being changed due to pressure from the OEM's and EPA. Zinc and phosphorus tend to coat O2 sensors and plug catalytic converters resulting in warranty claims as well as contributing to dirty exhaust emissions, so they are being eliminated from motor oils as we speak. These elements have been used in the oil since Noah was a kid to provide extreme pressure lubrication and protection from galling on heavily loaded engine components such as the cam lobe/lifter crown interface. The oil companies have no choice, they have to knuckle under to pressure from the powers that be. | Oil formulations are being changed due to pressure from the OEM's and EPA.

10. At the end of your 20 minute break-in period, drop the oil and filter and change them out. Drive the vehicle for 30 miles, altering the speed and letting the motor rev down from 60 mph to 20 mph with your foot off the gas pedal. Drop the oil and filter and repeat the EOS again. Change the valve springs to the ones that came with the cam kit. Drive for 500 miles and drop the oil and filter again. | 10.
