I have never had that problem with my truck, but with my wife's GC it happens all the time. More to her than me. We just reply that we saw somewhere on the internet that diesel gives better mileage and thought we would try a tank full and see. We used to have a Chevy Cruze diesel. Attendants would actually run out and try to stop us all the time. The Cruze was deleted and was an mpg beast.i have yet to run into another eco in the wild. Every ram I see around here has the hemi badge.
ive had guys say your putting diesel in, thinking I was making a mistake. I say yeah it’s an eco diesel. Even had one Silverado guy say I’ve never seen a diesel with duel exhaust.
