It's true that low sulfur diesel fuel is not as good a lubricant as the older
high sulfur diesel fuel. I live in California and when we switched to low
sulfur fuels, the California Air Resources Board actually paid diesel owners
for repairs to their injection pumps and injectors caused by low sulfur fuels.
But I would not worry too much because mercedes diesel injection pumps seldom
fail even if you use low sulfur fuel. And...you can always use a fuel additive
such as Red Line. However, the only time I had to replace injectors was after
using Red Line additive. My injectors started leaking after using the
additive. Although, I still don't know if there was a connection.
Re: Low sulphur diesel
Thank you for your reply.
Any idea what's the difference between the new diesel fuels in North
America and Europe?
ours<fuel> is good but i hear that the reason why we cant get the
diesels here is our
EPA / air people are making it hard to get cars approved.
NY & CALF are the worst
the case, minus a few cans!
M-B injection pumps are lubricated by engine oil so the fuel is
irrelevant. The low sulfur fuel caused some old rubber fuel lines and
"O" to leak and we were paid for those repairs.
The benefit is much less soot and a cleaner car. The back of my car
usually had a black soot film but not since the low sulfur fuel was
introduced. The sulfur is a non-topic now and life goes on.
