No offence to anyone but if you have to put a additive in your oil it's not the right oil.
I look at it this way. I build all my own engines and have for many many years. I have also been a Brad Penn (Kendal) user for those same 40 plus years. Oil as we know it has changed over the years and so has the quality of the metals used in our cams and lifters. Now throw into the mix I run alcohol and we all know the issues with that. (water moisture). Now with the 650 lift solid lifter cam and higher spring pressures that I run adding a bottle of additive and EDM lifters is cheap insurance. I have no issues running my engine for 3 years between engine freshen jobs. Wrong oil? I don't think so but what do I know. Hopefully when I freshen my small block next time I will grind my R3 block so I can run roller lifters and I will sleep even better at night.
