Hi I have seen this advertised occationally. Is it necessary? What form does it take? and how often should you have it done.

I haven't had any problems with the car, just wondered.

Have you used this? Was there a difference afterwards?
I do use the diesel version every couple of years as a cleaner , noticing a difference only in the warm fuzzy feeling rather than the car :D , but who knows

Yes snake oil to so many ,But i have my own reason. After a friend had problems with his engine and went and used the snake oil i mentioned before, to shift the carbon from his engine ,.. This did not change the situation .But after pulling the head off the 6 cylinder engine with 200.000 on the clock , i have never ever seen any engine so clean inside .Not a bit of carbon any where in sight ,it was like new ,. But the reason of the missing was down to a blown head gasket If Red X can clean the crap from his engine like it did,, so i am a believer yea yea

You need to start your journey of engine and fuel cleaners at the bottom buddy , nobody goes straight in at the top with Terraclean .
Begin with level 1 at £5 with Redex over a year or to , and as you develop knowledge and opinions on how good it is you progress to level 2 .
Level 2 is more expensive at £10-20 per treatment , including Wynns,Forte,Millers , by this stage you have more knowledge and bigger opinions on how good the level 2 treatments are and how much they benefit the car .
Also at this level you can tell other car beginners to start at level 1 for a year or two before progressing .
It’s very important that level 1 beginners do not use level 2 treatments in their cars :eek: !
Level 3 (£20-30) is for advanced users (like myself :D) who have been using additives of all sorts for years and swear by them , also you will be able to site how these more advanced level 3 products have benefited your vehicle :rolleyes:.
Products in this category from Archoil and Bardahl .
Level 4 is Terraclean , but because I am only level 3 I am unable to express an opinion on the level above ;)

the one everyone forgets is that oil breather mess, dust getting past the air cleaner and soot from recycled exhaust gas gets bakes into inlet ports... it wasn't better in the old days when the fuel was squirted in to the inlet port rather than direct into the cylinder as most tractors do (and becoming normal on high end petrol engines), but it made us feel better. All the fifth blocks the ports and this is why Terraclean actually works...

it decokes the inlet system and pretty much does this sort of thing to the fuel system - watch all 6 or 7

The only cleanser I'd use for cleaning inlet tracts is walnut blasting.
For any engine with direct injection (which is all modern diesels) is walnut blasting. Nothing added to the fuel will clean the inlet.

Thank you I will take a look.

Yes, but what if you do not have direct injection? I am not sure that mine has this. I think that it is sequential, but could be wrong.

Yours is petrol and port injection. Likelihood of carbon build up is very low.

Thank you, but do the actual injectors need a clean, or only if there is a known problem?

I think you are going round in circles buddy , you don’t have an injector problem , stop worrying about it all .
Chuck an injector cleaner in every few months for a few quid (or not) and enjoy the fact the car is working , something else is going to break soon enough on a 2005 car to take your mind off your perfectly working injectors soon enough .
