Hi,

As anybody had this carried out on their Roadster S? If so any positives or negatives?

I think it's been discussed before, the consensus was that the science smelt like BS mixed with old snake oil. Even this firms own explanation of the chemical process and caveats about how effective it MIGHT be are very unconvincing :)
https://www.engineclean.uk/how-it-works/

The Advertising Standards Authority have also upheld a complaint about the product because there was no evidence that it worked on current cars, the test data had come from 1977 and wasn't independent, and a clean done on a 25 year old Celica with 175k miles was ruled as not being representative.

As a result the ASA ruled that "UK Carbon Cleaning are not allowed to advertise with claims that their product saved fuel and increased MPG, prolonged engine life, restored engine performance, reduced emissions, removed carbon deposits from all engine types, prevented wear of engine parts, reduced intermittent acceleration cut-out and engine noise, reduced exhaust fumes, facilitated vehicle inspections for pollution tests (MOT test) or increased engine lifespan"

- or put more succinctly they are banned from claiming that it does anything at all! :lol:

Cheers Ewazix,

That's probably the most comprehensive response I've ever come across. But in a nutshell the carbon cleaning process does sweet FA?

No probs :thumbsup:

I did look at it a few years ago when I had a previous model Cooper S that was suffering with carbon fouling which is common on that model. It actually needed blasting with powdered walnut shell to shift it. If you think about it logically removing carbon deposits from an oven requires acid and scraping, temperatures and pressures are higher in the cylinder head so sloshing some non corrosive mumbo jumbo fluid isn't going to do much good. Carbon deposits don't seem to be a huge issue on these engines, so apart from using decent fuel there and giving it an occasional 'Italian tune-up' there isn't much to do regarding carbon.

They’re all roadsters, most of which have an S somewhere in the model name.

OP tell us the engine you have so that I can advise you as to whether carbon cleaning is worth it or not.

Alpina only did one engine for these cars. Keep up at the back :D

As this is the Alpina section and the OP's username has Alpina in it, I'm going out on a limb here... I think he has an Alpina Roadster S! :wink:

It's a 3.4 version of the S52 from memory.

All explained here...

But I'm intrigued to hear your advise (sic) on the merits of carbon cleaning between presumably what you thought would be a 2 litre 4 pot or 3litre 6. I'm guessing you must work in the field that we should take note of your advice :?

Hmm fair enough guys.

Seems like the engine (3.4-litre E5/2) is port injection and thus not worth a carbon clean as a good quality fuel such as V Power would already keep the exhaust and intake valves free from carbon deposits.

As a general rule of thumb, carbon cleaning is only worth it on direct injection engines such as those in the some of the E89 models and all of the G29 gen.

Back in the day, the navy used 'carbo blast' (crushed walnut shells) to clean the compressor blades on marine gas turbines. It was quite challenging to carry out the procedure on gas turbine driven generators because the carbo blast was burned off in the combustion chamber which caused the rotational speed to increase. There was a strong possibility that the lights would go out when the generator oversped and tripped!
Start the day with a smile, get it over with.
