Having just recently experienced with a lot of miles both the Jake (H3)and The Retarder (Libery Xl1) (or The Retardo as the Mangoettes call it). I have to comment.

Retarder Hands Down Winner:

Performs as intended in slowing the bus down. Does a much better job than the Jake. I can come off the interstate into the decelaration lane and use the Retarder without having to touch the brakes until it drops into first gear. I can't do that with jake. With the Jake I'm using the brakes a lot more than with the Retardo in the Liberty.

I know all the worries and comments about fluid temperature, and until a month ago when Jon posted here I thought the magic number was 230, but even out West, with some planning, I rarely exceeded 230. Now I know this means more frequent fluid changes, but I think this is a small price to pay. The bus definetly stops quicker and with less brake action with the Retarder.

I wish is was on the new H3.
