I chat with a lot of diesel owners at a friends truck repair shop and they are not happy. Medium duty diesel drivers that i talk to these days are fed up with new diesel regulations . They complain about losing business bc of repair down time.
The owners driving routes like Snap- On , bread and soda routes are switching back to gas trucks.
It must be pretty bad to unload $100,000 plus trucks prematurely.
If someone ‘claims’ mpg figures by using simple math counting used gallons and miles driven ,
the results are of doubtful validity.
