Just got back from a trip and was thinking along the way. I payed an average of 20 cents a gallon more than gas. My oil changes take more oil and I have to change the fuel filter alot more often than gas. Now I dont pull that often, but it sure seems that a gasser is a cheaper route to go. Seeing that a new gassser is about 10k cheaper than a diesel! Dont know how you could really even justify the cost difference.
