That was the first time i had any problems. ive run alot of it and i get better mileage out of it. about another days worth of driving to and from work in houston traffic and thats 80 miles round trip. thats the only problem ive heard out of it as well. unlike when the new ulsd came out and every one was burning crap up...lol as long as you feel comfy at where you get it, i say go for it.
