Re: oil with out zink
I use Lucas Hotrod too.
They did reduce the concentrations some years back. I'm afraid of wiping a cam lobe on flat tappet engines.
Bunch of guys in my Model-A club (I have one of those too) still swear by Shell Rotella-T. They do not realize that Rotella-T hasd been reformualted. They still buy oil based on brand. They do not understand you first buy oil based on the formual (chemistry) you want, then viscosity, then a brand you trust for consistensy and quality control. I am not wasting any more of my breath on people in my car clubs that are in their 80s and 90s.
I have used that Lucas addative, and I think that is some good stuff too!
