      I presently use Diesel-Kleen, gray bottle, in my 02 Golf, I have since first fuel-up. The engine is a little quieter and fuel economy is slightly better, and it adds some lubrication for the IP. I am considering an '12 Passat, if I get one, I will be using the Opti-lube XPD. If you read the scar wear tests on the ULSD, most fuels barely meet the minimum requirments for lubricity. The only one that I have read that easily meets the specs is the fuel from Irving, and that is still not that great. Because of the HPFP issues, and the associated costs IF something goes wrong, which seems to be rare, I will be using an additive as cheap insurance. Also, because of the HPFP issues, I am also going to see if the CAT 2 micron fuel filter is still available and if it will fit on the Passat.

      For those of you who do add additives, how much of what product do you put in, and how often.

      Every fill-up using this formula:

      Gallons of Diesel Fuel to Treat Ounces of Additive Required
      3 gallons 1 ounce
      40 gallons 16 ounces
      100 gallons 32 ounces
      250 gallons 80 ounces

      So, 15 gal = about 5 oz. No one runs their tank dry, right? I use a marked funnel to add the Diesel Kleen. Yeah, it stinks as bad or worse as diesel fuel! Gloves are good.

      Over adding doesn't hurt anything except wallet!

      I use a little splash of power service with every fill in all my Diesels. It's hard to get high cetane fuel around here, and it does make a small, but real difference. You can really tell on a car with worn out injectors, it knocks down the knocking

      I haven't yet used Opti Lube in my 2013 Passat but have been using it in my Ford 2008 6.4 diesel.
