I didn't know a diesel manual tempo existed
 

Cool!

Diesels are easier to hypermile. All you have to do is floor it and you're at top efficiency. Then use the gear shift to select as high of a gear you can tolerate for acceleration (without lugging and shaking your skin off of your bones).

I can't wait to get my 1985 VW diesel's timing belt changed and get it back on the road.

I only got to see the turbocharged version of this engine, in the early Kia Sportage.
