Diesel Injector Cleaner

[HW182]

Is it worth it? I’ve a 1.6 JX engine and was wondering if adding the diesel injector cleaner (the stuff that’s usually £4 a bottle) to the next fill up.

Will I notice a difference or is it all snake oil.

Thanks

I’d say it was snake oil, but I’ve no proof. The questions I’d ask are :-
How old is my engine? (~30yrs? Recon or original? Good recon or unknown “recon”?
What else might be wrong with it?
How is its performance? How might that compare to new?
And then:-
Is this stuff going to make a massive difference against everything else that’s going on with this engine?

I wasn't going to respond but have changed my mind, even though I don't do diesels.

£4 snake oil. On petrol engines the Forte cleaners are used by the trade and do work. However they will only improve things if you have a problem. Try putting some non supermarket fuel in, like Shell v-power, that has lots of decent additives. Costs more, but potentially better mpg - have a read around.

Just had my vauxhall Varvaro work van done professionally in the garage. Made little difference at £100. Have used the other pour in cleaners as well and there has been not really enough difference to notice. Cheep fuel and short journeys not good for diesels

they are cleaners and do exactly that, they wont recondition your engine or injectors, I use it regularly and it makes a difference on the heavy diesel fumes

The ones that need to pour into diesel are mainly kerosene. Does not harm, run cleaner, but does not clean a lot.
Real cleaner fluids like liqui moly are used as a fuel from their can instead the diesel from the tank.

Probably notice more of a difference with 2l of unleaded in a full tank of diesel like we used to do in the very old days
