Thank you all! If I keep my car, the truck may only be driven once a week or so in the summer. Probably more during inclement weather in the winter. Does sitting idle like that tip the scale significantly?
I've heard two different side of this: On the engine side, gas can tolerate infrequent use better than diesel with various add'l filters and injectors. However on the fuel side, the ethanal gas we have hear breaks down whereas I'm told diesel is more stable.
Certainly my diesel kubota hasn't had issues sitting a week or so over the years..then again it's a 2001 motor so probably less sensitive than the new truck motors with all the emissions controls etc.
