Doesn't change anything. If you actually read the PDF you linked to, its for B100 and it assumes long-term usage. And as said before, 1 tank will have no effect on hose lifespan but it will clean the fuel system's internal surfaces very well.

layback40, you basically call me a noobie with few posts yet you've been here less than a year and you're flooding the place with twice the post per day rate of myself. Now, did you have something to contribute to the thread?

There is no point wasting money in such a manner. As the PDF you yorself linked to said "Most elastomers used after 1993 are compatible with B100 (Viton/Teflon)."

B100 compatible hose is good to use if you are willing to spend the money. The stock rubber works just fine. Rubber hose has a service life regardless of the fuel type you choose. The stuff needs to be replaced anyway. Just replace it and move on.

Does anyone use a special additive to avoid valve adjustment? No, its normal maintenance, you adjust the valves. Brakes, tires, filters, ....rubber hoses.... its all considered a wear item.

And you guys in the pissing contest, can you take it offline? Really, just get out the rulers, see whose is the biggest and lets move on.

New injectors make a world of difference guys.

I am aware I sound like a broken record. I do not work for any Diesel shop nor do I endorse a place over another, I am just amazed at the difference they made on my SD for the money. I used Monark nozzles that replaced original Bosch that were around 235k. Far more linear delivery of power, better start up, better idle, more power, etc.

Previously I tried Diesel Purge and it may have made for a marginally smoother running motor, but it was nothing significant. Hell, I believe the adjustment of that rack damper bolt did more for me

I've had about 31 benzes now, mostly old diesels, I have not tried the diesel purge yet.

I might someday though.
