I don't have a Facebook access. What kind of nu. did you see on dyno. I am a firm believer in Lucas products, just getting into karting and have seen so much debate on oils for the clones.
Any oil is better than none.... Pick something and stick with it. I like Mobil 1. No walmart oils... Be prepared to get 5000 different answers though.
I have not used any Lucas additives, and have not had engine failures. Good oil used for a reasonable service life should not require additional additives.
This oil is claiming to have 3 times the amount of zinc compared to Mobile 1 and then they are also selling a break in additive pure zinc 1oz to 14oz. I would think there would be a concern regarding galvanic corrosion at this concentration. When two dissimilar metals are in contact one of them will suffer.
I can see it both ways. All I am saying it has worked in the past for me. Coming from cars, which I know is different, I do believe in it. I could see the difference in the bearing wear, both with and without it. Same oil, same change duration, marked difference in wear patterns. While I know no two engines are the same, I , myself think it does work. I would like to see if anyone has used it, and their thoughts.
