The mobil Delvac is dino, i use a lot of mobilgard 450, high tbn, @14, couse the sulfur content of diesel in this country is very high.
Any ways i have to keep track of a fleet of 25 units, crew boats and tog boats, as you can imagine i do usu a lot of oil, @ 15000 gallons a year, so oil is a very high expense for me. Since I buy mobil, they let me test the oil for free, so you can´t imagine the amount of test i do a year, and for any thing that crosses my mind. Needles to say i am kind of disapointed at Mobil 1, very low TBN for very few milles.
Actually a have te results foa an A160 mercedes, Mobil 1 did a lot better on that one.

The oil on the A160 had 7500 milles, the car had 15500 milles
Note the fuel in the oil.
