I can't say I've ever noticed any smell in mine, but since I drive a 24' straight truck for a living I'm might just be used to the smell
. My boss has a Powerstroke and during the winter time you prety much have to turn off the blower moter on the heater when sitting at lights until its warmed up, the thing just plain reeks of fuel till then.
One thing I have learned in my time(way too long) of driving trucks with diesels is always use gloves when fueling up .That keeps you from speading the smell of the fuel that is always on the fuel nozzles onto the steering wheel and other interior parts and watch where you walk to try and keep fuel off your shoes, there is always fuel spilled around diesel pumps. I keep a pair of leather work gloves in a ziplock back in the cubby hole by the rear door for fueling ,I have got some funny looks as I open the rear window ,grab my baggie and get my gloves before I do anything else
