| Phosphorus is a key component for wear protection in an engine and 1600ppm (parts per million) used to be the standard for phosphorus in engine oil. In 1996 that was dropped to 800ppm and then more recently to 400ppm - a quarter of the original spec. Valvetrains and their components are not especially cheap to replace and this drop in phosphorus content has been a problem for many engines. So why was the level dropped? Money. Next to lead, it's the second most destructive substance to shove through a catalytic converter. The US government mandated a 150,000 mile lifetime on catalytic converters and the quickest way to do that was to drop phosphorus levels and bugger the valve train problem. | Phosphorus is a key component for wear protection in an engine and 1600ppm (parts per million) used to be the standard for phosphorus in engine oil.
