My housemate recently bought a 2009 JSW TDI and I have a mid 80's MBZ Diesel. Reading the forums for the MBZ they make a big deal out of fuel additives due to possible lubricity issues with ULSD etc. I know the JSW common-rail TDI engine is designed to run on ULSD, but i guess my question is, should a fuel additive be used to ensure lubricity as with the older diesels engines from yesteryear or am i overthinking this? Just want to make sure my housemate has all the facts. He just knows to put diesel in it and drive it and will ask me if something goes wrong.
Thanks again.
