I am thinking about switching to Lucas oil products. I am wondering if anyone uses their products. I haven't really heard anything bad about them. Of course, they say they have the best thing since sliced bread. Genuinely looking for good, bad, and on the fence info on their Fuel treatments, 15w-40 High TBN engine oil, and their gear oils.

BTW, my truck is an 06 2500 4x4 QC. Is their Auto trans fluid compatible with our tranny's?

Thanks guys!
