no offense, but i don't believe that

i'd be interested in reading some factual supporting data if you have any leads though because i do believe that diesel engines are more efficient--i just don't buy into the idea that they are anywhere even close to that much more efficient

are you talking about biodiesel by chance?


...and are you getting 15 mpg in town or on the highway?

 

I will look for some sources about this. I do remember hearing and seeing this more than once. To be honest with you what I think was meant by the statement was that if all of the vehicles (on-road) were diesel powered then the US produces enough crude oil to power these vehicles. We would still have to import crude oil for heating, agriculture, and all other uses of oil. I do not know if this includes biodiesel or not. I guess I should have clarified my statement better as the way I said it was misleading.

Since I bought my truck in April of '04 I have averaged 14.92 mpg. This includes highway miles, city driving, some towing, some offroading, and the gas I burn doing random work around the farm. On a tank that is all highway I can get around 16. All other times I am lucky to get anywhere close to 15.

 

cool deal man, i'm just curious

i've done some casual research, and the best numbers i could come up with said that the u.s. imports well over 50% of the oil we are using now

i can imagine that the numbers might line up if it's just automobile fuel useage though, which is really pretty remarkable in and of itself considering how much driving we do here

talk to you later, let me know if you come across any papers or anything, i'm interested
