Diesel Fuel Additive
I just got my 2003 Excursion with a 7.3 Power Stroke last week. It's my first. I've read about the new low sulfer fuels and the problems with them not lubricating the engines. I bought some Rotrlla DFA. I just saw in the Ford manual that I shouldn't add anything to the fuel. They say it could do damage. What's should I do?

I've got 15+ years of owning and driving big rigs,
No Engine maufactures recomend additives be cause they just don't endorse them, but I have always use (LUCAS) upper cylinder lubracant (fuel additive) Seems to do well, i would mix it acording to instructions and run a tank full once a month, the last rig i got rid of was my own personal truck with 875,000 mls on the motor with no major engine repairs, so i cant prove it dosent work! DW

Time to pucker up
I have put gasoline in the diesel tank, 5% to keep the fuel from jelling in the winter.

Them old VW owners used gasoline in their tanks in the winter. Why do truck drivers talk to buggars? I had an employee use gasoline in the diesel tank, took out 2 pistons in about 15 minutes of operation after the gasoline was added. Also put the truck down for a week trying to get all them little parts out of the block. You do what you want, but my money goes on lucas, howe's or power service. They do test their product before marketing.
only my 2 cents
