I have used Delvac 1 all the time for the last 3-4 years in my tdis. . you can get it around here often on the local auto parts shelf, but its $25 bucks plus for a gallon, I always did 5000 mile dump on my tdis with the delvac 1 , on a cummins i always used rottella, just cause you need a lot of oil
$100 plus oil change gets expensive quick. . what is teh price on this new mobil1 turbo diesel?,... . and how much differnt is it from Delvac 1?
thanks
