You can try a bottle, no harm in it really. Probably wont do anything

Whatever you do, don't spray it directly down the throat of the engine's intake! I've heard of people do this so many times. Diesel engines have no throttle, they rely only on the amount of fuel being squirted into the engine to regulate power.

If you shoot a blast of aerosolised injector cleaner down there, the engine will happily burn it, and rev itself to death.

Add it to the fuel tank, not the intake. I've also heard it's possible to clean older diesels by mixing in a little petrol,(<10% of a full tank) but I wouldn't try that on a newer engine.

I've added it directly into the fuel filter when changing it, with good effect. This was on an old indirect injection diesel. I would be reluctant to do that on a commonrail without some expert advice.

Waht type of car you have?. I am skeptical. I added some Redex to mine last year. Shagging injector had to be re coded the next day. Not saying it was the problem, but i havent added since. They swear by a product caller Millers sport across the pond. The new injectors are programmable and very sensitive..

glad you posted that before I saw this as I was just about to suggest doing just that!:eek:

Anyway is it grand to do this with petrol engines?

I have also heard, from a petrol station owner, that putting in a litre of petrol for every 10 litres of diesel will do the same if not better job then the STP bottles of stuff.

Do these bottles only really work when an engine is very dirty and if you put it in every 6 months or so you will only get almost undetectable boosts in performance or whatever the bottle says its going to do?

People also add 2 stroke to diesel. Supposed to be good for newer common rails. Don't ask.

I just put diesel in my car.

Weirdo :P

Every 3 thousand miles I buy some fuel additive from halfords. Mentions cetane on the bottle and it does me for a few tanks of diesel.

On the back of the bottle it mentions 13.5% extra BHP!!

Is the boost noticable compared to driving with a tank of fuel without the additive?

Adding petrol to Diesel is a big no no for common rail diesels I have heard. The injectiors use the lubrication qualities in Diesel when in use and the petrol will distroy this.
So I have been told at least.

To be honest I can't notice the difference. There might be or there might not.

I used to get a bit of smoke coming out the exhaust every morning. It seems to have stopped or reduced radically since I started using the stuff.

why do you think your injectors need cleaning?

are you doing a lot of slow city driving? I have never put anything into a diesel tank only diesel, usually run the engines well over 300k Kms with no issues.

I talked to the mechanic who delivered my blocked injectors (on last mondeo) to a crowd in Laois who do this and confirmed process when I met a former worker there by chance in a lab.

The process is : Put the injectors in kerosene which acts as a good solvent in a container. Lower this in to a sonic bath(google sonicators). A sonic bath is something that the jewelary industry also uses to clean your rings (using water). It passes sonic waves through the surface of the water which aids in the breaking up of small particiles of dirt (any solids) which will dissolve in the solvent. Leave it there for about an hour and remove. With luck they will be working as new. Mine worked for 6 months before giving up and I had to get new ones. Reconditioning was half the price (very poor value).

I work in another industry that uses sonicators and is something I do regularly to remove small blockages in components.

Before anyone argues, I am not saying everyone does this but this is what the guys in Laois were offering and Kildare Ford garage was sending it's many blocked mondeo injectors there on a regular basis.

I've been using millers for about 12 months now, you do notice it when running seems to be a bit smoother, this is not the case when its not in the tank. I dont know what it does but I wouldnt say it is cleaning anything, just making it easier to burn fuel, like using a firelighter to light a fire as opposed to rubbing sticks together.

I used a product called BG 44k on my Hilux. It has the 1KZ-TE engine so older generation diesel.
I just remove the fuel tubing from the fuel filter and put it into the can of 44k. Start up the engine and let it suck out the contents. Did a great job of lessing the smoke from it.
