I also add an expensive tetra-ethyl additive that I had privately tested to insure the stated amount of lead was in solution (it is!). My corvair head temps are 25-30 degrees cooler when using this additive. I never have pinging when using this additive. I also add water remover solutions to my gas to avoid that problem as much as possible.
