Hey metro,
Thanks for the welcome and info.
That is some impressive numbers from "Dave" considering his truck weighs close to 4 tons!
Guess I should raise my goal for the mileage increase.
I know it can be done because I did another Suburban diesel conversion using a Cummins 4BT.
Best MPG achieved from the 4BT was 26 highway and 20-21 city which isn't bad.
I decided to do a gm diesel because they bolt right in and their inexpensive. Just have to know how to take care of them and they will take care of you
BTW,
I would like to do a yanmar 3 cyl. diesel conversion to a metro, I think 70 mpg would be achievable.
