Used 2008 Ford F-250 Super Duty FX4 4dr Crew Cab 4WD LB (5.4L 8cyl 6M) Consumer Reviews
Ford corporate recently told us that we need to test the diesel fuel every time before filling up our 2008 Ford diesel F250. This occurred after contaminants were found in the fuel and we now have up to $12k in damages. The truck has less than 70k miles and this is the second time this has occurred (first at 24k). Truck still under warranty. No abnormal driving, primarily highway and occassional pulling of a 3 horse gooseneck trailer. All scheduled maintenance, including fuel filters, was regularly performed by a Ford Dealer. No warning lights came on before engine shut down. Through postings on diesel forums and leasing associations, we are hearing this is not an uncommon problem.
I now have just under 130,000 miles on this truck and I have hauled tons and tons of rock, 5th wheel, and a car. I have had nothing but great performance, no repairs, and perfect reliability. I have the V8 and it has been able to haul everything including a couple of times overloaded with ease.
I bought this truck to replace my last 4wd. We purchased a 30' travel trailer and the previous truck just couldn't cut the mustard! This SD justs runs away with it! This is my first diesel as I never would pay the extra but I always wanted one. WOW! I shouldn't have waited so long. I have always loved my Ford trucks and this one is the best I have ever owned. For it's size, it gets decent mileage. I can squeak 17mpg on the highway driving 68-70 mph. If I drive 80 mph, it get about 15mpg. Combined city and highway and driving pretty hard, I get 14mpg. Not bad for a giant, heavy truck. I had a 76 Chevy 4wd way back when that got 10 mpg and if I were really careful I could get 11mpg!
Absolutely the worst fuel economy of any truck I have ever owned! I only get 7 miles per gallon towing a utility trailer Ford should be embarrassed. Ford's response to me when I questioned the gas mileage was they are not responsible for mileage. You bought it, you own it, as long as it meets "factory specs" it's my problem. $48,000 truck and I get 12 MPG daily and 7 MPG towing and Ford says there is nothing wrong. I will unload this thing ASAP and never buy another Ford. The fuel tank is not only smaller than my 2005 F250 but at 7 MPG my effective range is about 125-150 miles..wow doesn't that make travel fun
OK I will admit I have an 6 inch lift with 37 inch tires but i get no better than 12mpg going easy on the throttle on the frwy and 7 mpg pulling my 7000 lb trailer(total B.S.). My V10 did better than this, what gives? Is changing the gear ratio to 4.30 the ticket for some improvement over the 3.73. This truck is history unless something comes out about improving the mileage
