This is normal for this time of year &#8211; busy shipping season for christmas gifts, harvest time, refineries gearing up to produce heating oil &#8211; and quite a bit different than previously in the year. At one point #2 ULSD was over $1\/gallon cheaper than 87 octane unleaded gasoline.<\/p>\n<p>But, folks have a hard time getting over this &#8220;diesel is more expensive than gasoline&#8221; stigma. Why they can&#8217;t do the math is beyond me, but here is an illustrative example.<\/p>\n<p>I just filled up my 2006 VW Golf TDI at approximately the same mileage at which I would have to fill up my previous vehicle, a 1995 Volvo 850.  I will use the lowest observed prices for both #2 ULSD and 87 Octane RUG and the overall fuel economy calculated over several thousand miles for both vehicles.<\/p>\n<p>1995 Volvo 850: overall 26.3 mpg fuel economy<\/p>\n<p>2006 VW Golf TDI: overall 43.4 mpg fuel economy<\/p>\n<p>The lowest observed price today is $2.739 RUG; $2.899 ULSD.  At these prices, the 850 would have cost 10.4 cents per mile for fuel. The Golf TDI costs 6.7 cents per mile for fuel.  Even at $3.234\/gallon for the AWOC B11 I normally fill up with (at least often enough to maintain a minimum of B2 in the tank at all times), the Golf TDI would still only cost 7.5 cents per gallon.<\/p>\n<p>Keeping the Volvo would cost at least 2.9 cents more per mile, or 38.7% more than the Golf. Not to mention the two grand in work it needed immediately&#8230; and a car with 160k miles on it is going to start requiring regular replacement of non-trivial parts.<\/p>\n<p><strong>Remember folks, the price at the pump is irrelevant, what matters is the cost per mile<\/strong>.<\/p>\n<p>Oh, and the Golf has gone 800 miles on a single tank. The Volvo did well to go 500 miles on a tank&#8230; a tank that was at least 3 gallons larger. 38.7% more per mile in fuel sounds pretty bad right now, and that&#8217;s with diesel that&#8217;s 50 cents per gallon more than gasoline. Just imagine what it would be like this summer when ULSD was a steady $2.999\/gal and RUG was at $4.039\/gal &#8211; actual prices I observed. (hint: the Volvo would then cost over twice per mile in fuel than the Golf&#8230; 122% more expensive)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Right now, diesel is more expensive than gasoline.
