General Are you using Mannol Ester Diesel additive?

Hi,
Anyone is using Mannol Ester Diesel additive? Or just me?
Apparently there will be no any difference in fuel economy but it suppose to save fuel pump/injectors for longer.

I have tried it on a couple of different makes of diesel cars, a sort of clear treacly substance slow to pour from the can. Reminded me of a petrol engine additive that a company used to sell along with a spurious car warranty back in the 1970s, I can't say I noticed any improvements then or now.
Tried it "more with hope than expectation".
