Walmart for me too.
I can't seem to find anyone in my town carrying Spectro 6 speed oil. They carry other oils, but not the 6 speed oil. I was wanting to give it a try. I can get it online, but the shipping etc. I run syn 3 with a dash of lucas in the trans now. It is fine, but I have heard a lot about the 6 speed Spectro. Actually, not heard, read about.
