Best additive for TDI?

i understand the ultra low sulfur diesel is "dry" and can damage your fuel pump, which can in turn damage the rest of the engine. there aren't any bio-blend pumps around here, and opti-lube is HARD to find without paying ridiculous shipping costs (and it's pricey). i was looking at stanadyne lubricity formula (apparently endorsed by VW). any other suggestions?

    Best additive for a TDI as per the manual: nothing.

    You should speak to your franchised VW dealership as regards the quality of diesel fuel on the US market. I am sure VW thought about it. Your TDI is very much an old generation engine now.

    i used to drive an '81 Rabbit diesel, i just poured a quart of transmission fluid into the tank each time i filled it up. not sure if the newer TDI cars can handle this, you're better off asking on VW Vortex.

    Since you have a TDI you don't have a injector pump (fuel pump to you) and injectors are built for low sulfur fuels don't worry about it.
