Diesel Injector Cleaning Fluids

[g-unit]

Hi! There are many injector cleaning fluids available at our service stations. In fact Toyota too have their own such fluid. Do any of you guys have any experience with the use of these fuel additives? Is it any good? And most importantly will regular and proper use of these cleaners prevent manual injector cleaning?

The reason for my query is that my Hilux (brand new Thailand model) has done around 138,000 k.m. Since of late it has developed a vibration on early morning start ups and an odd clatter from the engine as well. It gets back to normal running once the proper running temp is reached. It reached a rather alarming level this morning hence, I spoke to Toyota Lanka. They seemed pretty sure my injectors were blocked. It seems that it has come to a level that the injectors have to removed and the cleaning carried out the old fashioned way. The manual advise the use of their cleaning fluid initially at 75,000 k.m and every 45,000 k.m afterwards. I used it initially around 115,000 k.m. So it clearly has gone way past the manufacturer's recommendation. I most importantly it hasn't worked (for me at least).

Also a word of advice for fellow owners with cars with common rail diesel engines. It is advised that the best place for any work in relation to the engine be carried out by the respective agents as many owners have learned a bitter lesson after work has been carried out else where.

Hope to see some constructive comments. Cheers guys!

P.S : Any idea how much it costs to get the injectors cleaned at T Lanka?

I hope u have a phone with u,

if not go to a phone both and ring toyota lanka

By the way thanks for the advise about 75k

But don't use these cleaners in vehicles with catheletic converters, some can destroy them.

Yet prado and hilux owners need not worry their tail pipes are less complected than a toilet plumbing,

But in European cars santafe s and sorrento s there are catheletic converters.

When you spoke to Toyota Lanka, why didn't you ask for the rates as well ? I know sounds silly but seems like the obvious thing to do. I've had my injectors cleaned manually by my mechanic and he did a reasonable job. I think even if they are fairly blocked you should still see an improvement after a chemical based cleaning. Since common rail diesels are quite new, not sure who to recommend apart from the agents of course. In the past companies like Macro Autotech have done a reasonable job with my petrol injectors.

+1 Utter rubbish from a misleading mutt!

@Toyotasucks, please do spell "Catalytic" properly, some might take your "catheletic" as a religious insult.

I used to add wurth injector cleaner about 2, 3 times an year for my car.

But gotta say when i eventually did a manual cleanup there was a noticeable difference unlike with wurth fuel system cleaner.

IMHO nothing beats a proper manual cleanup. Also you get to see them injectors first hand

No idea if the procedure is different on DI motors cos the injection is different.

FYI the Hilux does have a catalytic converter. It's not just in European and Korean vehicles.

The users manual of one of my vehicles said

Not to use fuel additives that would affect the Catalytic converter

Is this wrong
