Is Injector cleaner needed now we have Shell's...

....new diesel? This is supposed to have some kind of cleaning fluid in it isn't it so if we run on it all the time is there any need to run injector fluids through the system every now & then?
I'm asking as I've just bought a Volcane TD (my first diesel) & am wondering whether to just run it on Shell's diesel or whether to run some cleaner through it anyway.
Cheers,
Ian

The bloke who MOT'd one of my cars last week recommends it. His suggested tretment was Forte's.

I've tried Shell Diesel Extra a few times now in my C3 HDi, and ignoring its cleaning properties, its performance is nowhere near that of BP Ultimate. If you are using either of these fuels you should in theory avoid having to use additional cleaners.
As for whether you should use injector cleaner on your newly aquired Volcane, then the answer is yes, use some, the worst thing it will do is make no difference at all.......

Thanks guys [:D]
Where's the best place to get the injector cleaner from? I've noticed a few in Halfords when I've been in there for other things?
Cheers,
Ian

never used injector cleaner before but read about it a lot on here. Might get some then!

Miller's "Diesel Power"
From specialist performance shops. or specialist sites on the 'net.
(which says something...)

I use redex diesel additive every time I fill up.
But I don`t use shell the BP or Q8 is the best value for me

I've tried a few different types, I only found one that made a big difference (may have been fortes but I forget...). When I have had Wyns diesel injector cleaner (or whatever its called) in my tank, my mpg dropps by 3 mpg or so on that tank, and there is a little effect (1 mpg drop) on the next tank too.

I use Fortes diesel additive in my ZX 1.9D, I can't say it improves it as I have never run any tests, but the car runs well, starts easily and is economical. But:-- Using fortes petrol additive in the Mazda 323fi 16V made a BIG difference, both in better performance and economy.
I also add Molyslip to my engine oil.. Reason being.. When I worked in inspection as a young engineer we had a machine that comprised of a removable dish base, that was driven by an elec motor, above which was a sort of hydraulic ram/press. We used to place 5 ball bearings in the dish, add some oil, spin the dish at a fixed speed, and apply a downward pressure by lowering the ram onto the bearings.. [8)]
The idea was to test to destruction, i.e. run under heavy compression untill they started to smoke and screech, we then recorded the time and pressure.. Adding 'molyslip' to the oil made a very dramatic difference to any/all tests, it was by far the best lubricant/additive available at that time, and was used in all the pumps and compressors the company produced..

Engine oils have supposedly improved a great deal over the years. I'd be interested to know whether or not the additives still have any measureable useful effect with modern oils...

Against all advice i put a bottle of Slick 50 in my td and it runs a lot better (smoother and slightly more even) after 6 months, In my old car I changed the oil every 5000 miles and put molyslip in every third oil change, I realise this was probably overkill but the oil used to come out just a little bit darker than when it went in, when i took off rocker cover at 96000 miles it was like a brand new engine inside, I am convinced that it could have run for another 100'000, When I bought the car at 40'000 miles it was very cruddy inside!, I to have seen applications of slippy products and the results speak for themselves.
