Funny you should ask about Lucas. One of my employees swears by this stuff called "Lucas oil stabilizer" Every thing he owns is junk. In fact his car is an ex taxi cab. And he dumps that stuff in every thing he owns. Including his old Noma riding lawn mower.
I think if you keep your oil changed and put in a good oil you don't need to add any thing to your oil. The only time I used additive in my oil was years ago I put 3 cans of STP in a car to quite down a rod before I traded it in.
