just wanted to know if anyone uses a race oil with zddp or zddp oil additive and if there is any good or bad effects .zddp is for push rod motors that helps to make less wear on cam and lifters. maybe it will make less wear in the rotor housing.
Castrol GTX 20/50 is what I typically use. It burns well too. Rotor housings are like cylinder liners - eventually they have to be replaced. I just wish something could be done so both ends of the apex seal don't chew into chrome.
