I also have a 2015 eco diesel
I also have a 2015 eco diesel with over 8000 miles on it now and I love it. Some of the concerns I heard about the truck on other web pages is that no one factors in the DEF fluid or the high cost of oil changes. Let me tell you if those are your two concerns/complaints we are all doing good. For my self personally its not even really about saving money with the better fuel economy. Lets face it, it would take us a long time to make the extra $5000 back in terms of fuel savings. However most cars/trucks have you returning to the gas station within about 400-450miles. My eco diesel gets me nearly 700miles before returning to the gas station. That in itself is huge in terms of TIME savings. On a side note I have a friend who had the half ton Toyota. He loves to trailer his bike every year from FL to Sturgis for the bike rally. On the way up he actually ran out of gas because in that truck he was only getting about 150 miles per tank and he hit a long section of highway without a gas station. On the way back he had to buy gas cans so he could pull over and fill up on the side of the road. He later traded the truck for the eco diesel and made the same trip with out needing gas cans. Wile pulling an 8000lb trailer he was able to cover over 400miles per tank. As for the DEF. my truck will make it well into the oil change on a single tank of DEF. I'm not sure how big the tank is but DEF is not that expensive and it will last me at least 10,000miles if not more. The oil changes are a little pricey but once again its only once every 10,000miles. To date I only had to return to the dealer 1 time in 10months of owner ship and that was to have a spray in bed liner installed per ur purchase agreement. Love this truck.
