You just created a monster Buster. Someone will be here shortly to exclaim they get 21K on every oil change with Supertech.

What I do like about the claims made is though is gives you some level of confidence in the product you're buying. An oil designed to handle longer drains is going to have to be made up of good, premium components. You get what you pay for. Someone people want the best, but only want to pay $2qt. Not gonna happen unless you get a clearance blowout.
