Oil Additives Solid Cam??

I caution everyone not to get caught up in the ZDDP oil discussion because unless you're a Petroleum Chemist there's a big pile of disinformation floating around the internet especially as it pertains to oil classifications.

The simple truth is that engine builders such as Hughes recommends a minimum level of 1200 ppm of ZDDP and according to Valvolines own spec sheet their VR-1 has it so I use it.
