Put my cataclean (not to be confused with terraclean) in the fuel tank. It really stinks 😝
Yes it stinks, still not figured out how they get the cat to piss in such a small spout
I've used catac;lean for many years with good results(on PETROL cars in the family fleet.
)
some say it is snake oil
I usually run the tank down to 1/4, add cataclean, drive till the fuel light comes on, then refill the tank with fresh go go juice. just before MOT
I don't know how effective catacleaan would be on modern dirty diesel cars with DPFs
Good luck with it Mr Stemo
