Yeah, I'm not suggesting don't use lucas, but I would suggest trying many things before going that aggressive. I do believe no tick is better then tick, and if you have to go there then that would be ok. One thing someone could do it just use a thick oil like 20/50 or 15w40, that is likely what you did. You might want to get a uoa. The bottom line, when you use lucas as a strategy then you are using viscosity as your strategy. There are ways to skin that cat a better way without diluting your oil's additive package. There is no secret sauce in lucas, it is just a thick oil base, that is their trick.
