What is the best slick 50 or lucas oil?

Answer 1

Actually they are about the same. The real question is what are you trying to accomplish. By adding either one to your oil you are actually making your engine oil about the same consistency as gear oil. Modern oils have all the additves in them that are necessary for good performance. Both of these products are only really worthwhile if your engine is severly worn out and then they are not really all that effective. Spend your money on any qaulity motor oil. I personally like Valvoline but all ASE approved motor oils are good. By the way the little tricks like showing you that Lucas or Slick 50 won't run off your cylinders at night are just foo foo magic. If it runs out of the bottle it will run off you pistons and rings. Any oil will remain well enough to prevent start up damage. Having said all that if you are storing an engine for a long period a teaspoon of either in the spark plug hole will help save your engine from locking up. Also Lucas has a very good Power Steering and transmission leak product. Good luck
