What are you using ?

I don't like "scamsoil".

"It is grossly overpriced, often you have to go through their pyramidal "dealer" network to buy it, and there is no real (valid, scientific) support for the big claims the Scamsoil people make about its performance. Their handwaving and smokeblowing about why their oil is not API approved amounts to…umm…hold on a sec, there's a word for it, lemme think and I'll remember it…oh yeah: LYING. I try to avoid buying from companies that tell lies to try to get me to give them money."
