Even though I enjoy taking the odd cheap shot at Mobil and the iron thing (its old, but still fun), they also seem to make a very good HM oil. Up here its sold as "Mobil 2000;" Were I to switch at some point to a HM oil, it would be one of my top picks - so long as I could verify the only difference was the label. GTX HM and Maxlife are my other two choices, but a lot of that is because selection here is more limited, and where I'm not running a HM oil, I haven't spent a lot of time comparing them all.
