Here is my deal... I drive a F-250 Super Crew gas v-8 (5.4l) as my daily driver. When I bought it. I don't know I'd be using it to tow a 28 foot deck boat so needless to say its under powered, actually its under powered when its not pulling anything. I currently get about 10ish miles per gallon and 7-8 when pulling the boat with regular gas containing up to 10% ethanol. Our trip to the lakes is only a 14 mile round trip but we have taken it on trip as far as 150 miles and plan to take it on longer trips so I'm considering trading it for a diesel.
So my question is what kind of fuel mileage are you guys getting in your diesels? In our area, diesel is currently cost about 17% higher than gas so I would need to get at least 12 to break even.
PS... if you are getting 20 mpg and everyone else you know with the same truck is getting 15, please don't bother posting or share why you are getting so much more.
