Please do, and report back on what you find..
I can only tell you that the Mercedes guys are the ones that suggested it, and I know I was a little skeptical, but now I know that the Diesel Klean works on my mercedes.... I really cant say I notice any difference in the way it runs with or without... It only had 72hp when it was new, and I am sure a few have escaped in 200,000 miles!
I would have used it just for the protection it gives on these low sulpher fuels... the MPG is a bonus! I like the fact you can buy it anywhere, and I carry the can in the trunk, with one of those 2 stroke plastic syringes... and I just squirt about 3oz in per fill of about 10 gallons(my diesel is only like 14 gallons, but that will take me over 400miles!).
The diesel Purge was noticable when I ran it thru the fuel system, as the engine note softened, and it just sounds smoother than it was. I did not notice any MPG changes, but that is maybe because I put 17x7 wheels and tires on at that time... it may have negated the difference.
