I've used it in the past, but it's pretty pricey now... I tried a straight dose of 2 stroke oil 
& PS diesel kleen 50/50 on my Jetta & it seemed to work well when I changed the

some other problem.

I'm not sure the rack would hold the block! Besides, it's a brand new unit, so I don't 
want to break it in just yet...
