Lucas oil diesel stop leak additive

Has anyone tried this yet for an oil leak. My onan generator started leaking and just filled up at a truck stop and saw Lucas oil sells a Diesel engine additive to help stop leaking. Thinking of trying it to see if it works. Let me know your thoughts.

    I've had good luck with Lucas products. What is it going to hurt if you try it?

    I've used Lucas products for years. I was a service manager for a while, after I retired form the USAF. We used it on a few different issues, and I can tell you, it works very well. Can't say for sure it will cure your leak, but for the money, I'd certainly try it, before a gasket set.
