Yeah, Lucas is just conventional gear oil there is absolutely nothing special about it, doesn't even have anti wear additives. Been more than a few lab tests on it which shows it contains nothing but very low grade 90w gear oil.

I recently did a test with the Rislone Cat Complete which worked amazingly for my Kia Soul that needed to pass an emissions inspection. It worked better than I expected. This product shown on this video was made by the same company (Rislone) and I had already developed some respect for the Rislone brand. Of course, my hope has been shattered considerably. While I didn't expect this to completely fix the problem, I had hoped it would help a little. It didn't do anything.
