always use additives in your fuel. the diesel that is made today has half of the lubrication properties in it, than it used to. i use Amsoil diesel additive. increase in mpg as well. i used to own a trucking company and used it as a test- and i actually a pretty good increase in mileage.
fuel and oil arent enough now days, with the low quality diesel that we buy at the pumps. if the **** gov. would make b50 or b100 mandatory then there would be no reason for additives, except for winter and water times.

I never ran a tank in my TDI without Power Service. It increases the cetane and increases the lubricity of the fuel. ULSD is a very "dry" fuel compared to the old diesel #2 I believe it was called.

I never had any issues with fuel gelling in the wintertime - even down to temps of -10*F.

I always kept a bottle of power service, 2 gals of diesel and and a bottle of diesel 911 in my trunk. Some guys even kept a new fuel filter in their trunk as well. Even though the mechanical knowledge doesn't transfer, there's a lot of good info/practices over on tdiclub.

thanks for that comment. i posted earlier on how the ulsd fuel isn't as good as the old number 2 as well. and someone commented and said no more than 2% of bio is needed. BS tear the motor down and see how long your fuel system parts last with out proper lubrication. must use additive now days, since they took the sulfur out of the fuel. the diesel motor was NEVER designed to run on petroleum!! Rudolf Diesel designed it to run off peanut oil.

ULSD is the worst thing the government has done to diesel, except for letting the oil companies raise the price over gas. which it should never be higher than gas. in mid 2004 the prices flip flopped and diesel became more expensive. needs to be flipped back. the public would buy more diesel powered vehicles if it was cheaper at the pump. the gov needs to learn a lesson from the Mexican gov. they mandate the price of fuel, so the **** oil companies can screw the public like they do here.
there needs to more bio in the fuel to make up for loss in sulfur. the **** we get at the pump is so dry now days it needs to be supplemented !
