fuel additives

[tails]

anyone add anything to the fuel,
redex etc,
if yes any difference,and if not,why not.

I tried millers ecomax....didnt notice any tangible difference.... I occasionally use a premium fuel like ultimate or V-power but my car isn that old, and hasn't done that many miles so I'm not sure I would really see a difference. I just put that in every so often to keep it clean (arguably)

I would imagine they could be useful on a really old/high mileage car to clean some crap off.

Otherwise I wouldn't really bother....personally

Tried redex in the old Volvo and it stank of rotten egg on long trips til that tank was empty.

Miller's in the current no real difference.

Currently using archoil 6900d which makes it feel a bit more punchy when using standard supermarket fuel. That could be down to the map on my car though.

tried the v-power a few times myself,didn't notice really any effect,but my pal uses it all the time in his vw t5 van,he recommends it ?
it sure adds up at the till though ££££

This era of engines and oils don't really need additives like engines of the past did. So adding things just puts driving costs up with little improvements.
IMO of course.

For general running there is no need to add any additives and currently no mainstream manufacturer recommends any.

on older, high mileage cars there may be benefits from cleaning the fuel system but the only way this really works is running the engine on neat cleaner like liqui moly diesel purge (or a tankful of 90/10 diesel/petrol mix).
