Fuel treatment(might be the right word?).

I did that with the SV and it hurt quite a lot.

Also with the XJ there's the spigot thing on the filler cap which leads this to be ineffective

The stuff in the link looks more like a detergent (dispersant) than a co-solvent (like IPA) from the amounts and the way they say you can use it in diesel or gasoline (in between the pseudo-science, or BS as it's also known). Waste of time as already said. There isn't really much you can do to the fuel to make it "better".

Zacly. Fuel formulations are pretty incredible these days, difficult for us mere mortals to improve it!!!

A small dose of IPA every few tanks to let this burn off seems like just the ticket.

Sounds like a good plan... I just bought some silica gel off fleabay - I'm going to put it in a cotton bag tied with string and leave it in the tank, see how long it takes to hydrate fully. Might be a good solution for the condensation YC, I'll report back

Apperently not if it's water in fuel, but there is a unofficial test that supports 2stroke oil in diesel, mix ratio 1:200, which is a better addetive than any off the "super" diesels you can buy at the petrol station. Takes down soot, brings up mile pr liter, and is just overall good.
Maybe our resident chemist can fill in the gaps

Maybe silica gel is your next project yc?

Come meet the GM at loomies some time, I can let you have some colour changing stuff for free if I know in advance.

Sound like you're dealing, "First time is free for the colour changing stuff"

Nah, I've got a load from work but hardly ever use it.

Gave fallout some when he was trying to dry out an old car.

There's a lot of anecdotal "information" around. If you want to just read that instead of reading actual answers then go for it. If it were that easy don't you think someone in petrochem would have noticed?

[yorkie_chris]

I read that pump (ultra low sulfur) diesel is a p*ss poor lubricator compared to ye olde diesel due to environmental concerns leading to less and less heavy oil fractions and sulfur in there.

I wouldn't be surprised to find some truth in it.

Dont know about ultra low sulphur but that was certainly true about the switch from leaded to unleaded petrol.
