Well the truck was below 1/8th a tank when I realized I needed fuel! I headed to the gas station near my work and filled up. I noticed it only took me $37. 01 to fill up and then I saw it. I filled up with dyed diesel. Cetane rating of 40 just like the taxed stuff except this is $. 20 cheaper! I hope I don't get stopped at one of those fuel check stops. I've only seen one in my life but I can only imagine the fine!
