FYI, my truck is a 2007 w/5.9L, the 2007.5 is when Dodge came out with the 6.7L "ULSD only" engine.

Unless I'm missing something... Without any specific fuel problem I am trying to mitigate, I think that I'll just splash some B100 in the tank, just to increase or add the lubricity back. (It ranks at the highest for lubricity anyways and costs 25 cents less per gallon.)

Bingo we have a winner

absolutly...............50;1 ratio of bio will give ya a 415 lubricity rating..............life dont get no better than that

now keep in mind this does absolutly nothing for diesel fuel gel point.....it actually make sit worse so ifin yer in a cold climate you better run an additive to lower the pour point

I would love to run B-20 year round but there is NOWHERE for me to buy it :argh:

We have B20 at 4 stations that I know of and a plant that makes B100. Alamo BioDiesel

I don't worry about it getting that cold too often in South Texas. :yeah:

lucky dude
