I hate that all three vehicles in my household are diesel. I have no where to dump old fuel from my UTVs and snowmobiles at the beginning and end of each season. Luckily, my neighbor's son took the 21 gallons I sucked out of my snowmobiles at the end of the season last month to run in his Honda.
Our first diesels were VW TDIs. They were incredibly thrifty and had plenty of get up and go. Afterwards we upgraded to diesel SUVs due to living in Colorado and needing 4wd.
After wife got her Grand Cherokee with a 3.0L Mercedes Benz diesel in 07 and especially after I got a hot tune for it, she said she will never go back to a gasser. She loves the torque and ability to be doing 80mph on an onramp in order to merge on a 75mph speedlimit interstate, I-25. Having a 7,200 lb tow rating is nice too!
My ride is an 06 Jeep Liberty CRD with a 2.8L turbo diesel. It has a 5,000 lb tow rating and gets 30mpg on the interstate with a Green Diesel Engineering ecotune.
We just got rid of our Ecoboob F150 and upgraded to an F350 with the 6.7L diesel. All I can say is WOW. 14.5 mpg in mixed driving and about 17 on the highway. I'm hoping the fuel economy will get better when it gets more miles on it. I didn't noticed max fuel economy on all my other diesels until about 25k miles. I get it takes a long while for those rings to seat and things to loosen up a bit.
Don't get me wrong, I still like gassers. I think gas engines make good lawn mower, weedwhacker, UTV/ATV, and snowmobile engines.
