I wonder if it would be appropriate to tack on one more advantage of gas: less worry about water in the fuel system?
I bring that up because I am looking at a Grand Cherokee with 3L diesel and have been reading the owner's manual and diesel supplement online. The supplement states that if the warning light for water in fuel comes on, one must immediately stop the vehicle, shut it off, and within 10 minutes crawl under the vehicle and open the drain... because continued operation could ruin the engine! That has alarmed me somewhat.
In 14 years of ownership I have never had a water in fuel issue. Never. I do follow recommended filter change intervals and buy my fuel at stations that sell a lot of diesel.
