Is ULSD a magic pill or what?

Well, I'm just kidding about the magic pill, but last Friday I finally got my hands on some ULSD for the first time, and my '96 E300D had the honor of being the first one of my cars to try it. I must say I'm impressed. I can't comment on the fuel economy yet and I have read reports of mileage dropping with ULSD, but what's amazing is that so far I can't smell the exhaust anymore. Usually the way I sample it is by putting my hand under the exhaust and then smelling my hand. With LSD, there was always a diesel smell, kind of that typical sweet, bus-like smell. But with ULSD I could hardly smell anything. I guess that sweet diesel smell was from the sulphur. Another amazing thing that I have a hard time believing is that my IP's o-rings stopped leaking on ULSD, at least for now. I guess they were swollen and the ULSD, with its seal shrinking tendency, reversed the aging process somehow, but who knows. Has anyone experienced anything unusual with ULSD or any mileage drops?

Interesting, no more diesel smell. That's the one thing I hated about diesels, I'm glad it's going away.

I like the smell when B100 is used.

I'll miss the smell. Always reminded me of boating.

I filled yesterday for the 2nd time with (Shell) ULSD. I was concerned that MPG was going to be way off but it wasn't the case. Fuel calcuation showed my 2nd best MPG ever. Smoking is virtually non-existant on this 2nd fill. Not the case with the initial fill...probably purging dirty fuel. Odor is minimal. Car runs nice

Any lubricity concerns folks? Do the engines run and sound the same as before? Better worse?

I looked at the pump when I got fuel today and it had the LSD diesel sticker on it.
