So I got this Idea actually from this site. If you arent adding alittle motor oil to your diesel, you should be. I have about a two mpg gain. The only thing that I contest is they say it should just be SAE 30. I was brave and went with some 99 cent a quart oil I seen on the shelf that was 10W40 which worked just as well. Funny story. Those guys at the auto parts stores know everything apparently. I got out of there with the cheap oil but not after a long argument about what the W in for example 10 W 40 means. I know alot of people think it means Weight. According to the Society of Automotive Engineers it means Winter. Anyway. Dump away and get better fuel milege from Ultral Low Sulfer Diesel. Thanks for the tip guys
