Today I accidently put 1/4 tank of Low Sulphur Diesel in my 2011 Jetta TDI. I didn't notice until I had put 3 gallons in that it wasn't ULSD. The VW dealer said I was OK and to fill it up with ULSD to dilute the LSD. Should I be worried?
No need to worry.
The last offical report I overviewed had fuel compliance at 99% and that was to day the 1% in error was a supplier process problem.
i.e. all refiners at this point are creating ULSD.
Now in terms of labels / stickers, they are not there yet at all ..... this is a funny area, the refiners and haulers are doing their part but it is not up to them to re-sticker / re-label the pumps. Guess who could care less about a sticker ...the mini-mart owner.
