Percent fuel content higher than my other truck
Using the Caterpillar oil sample program my recently purchased 2002 12.7 DDEC IV had a relatively high soot of 58 and a fuel content of 2.63%. The overhead has been run and the mpg averages 7.5 - 7.75. My 2006 c-13 cat has a soot of 22 and a fuel content of 1.32%. I drive both trucks the same way and same routes. The Detroit engine has 670k original miles. Should I add snake oil to the fuel, will it come out of it, and what would be the best snake oil to use?
Is this a good question?
