What exactly is it? i needed some fuel and i pulled into a shell station and saw they have the ultra diesel, so i got some. its 3 cents per liter more than their standard diesel. is there any benefit to it?
Basically it is dosed with the additives we anal retentive would put in after filling

is what I understand.
I think it's just a money grab. I don't notice any difference with it

same here. i noticed a difference when going back to gold diesel though. and an even bigger notice when using power service.
my personal opinion is to go with regular diesel & a cetane+lube additive. who knows what 'junk' they put in. although shell is supposedly 'ferarri' fuel :roll:, but then again i know of no diesel ferarri's :lol:
