Carbon Clean worthwhile?

16 posts in this topic

There is a lot of hype about carbon cleaning the engine to remove carbon deposits. However, from what I've read, it is much more relevant for direct injection engines on newer cars that tend to build up carbon deposits, esp. those that do a lot of short journeys or idle a lot in traffic. I understand that older injection engines are much less susceptible. The owner of the specialist garage I went to recently thought it wasn't worth doing on an E39. Has anyone had it done and did it make any difference? Did you see a lot of black smoke coming out of the exhaust during? Thanks!

Albeit slightly different, I had mine terracleaned a year or so ago and the difference was black and white.

 

So much power was given back it was gobsmacking, a lot more lively and gained a little more mpg back too.

 

In my opinion, a terraclean is well worth it.

Personally for me, it worked well

 

The wife had a 1.9 TDDi Focus at that time; typical Ford, blew black smoke everywhere, had only covered c70k miles! It ran so much better after a Terraclean, a lot cleaner, much smoother and quieter too!

 

I had my E38 728i done at the same time, it only had 106k miles on it, but the car still ran very smooth and quieter afterwards (was quiet to begin with)

 

I do feel though that diesels will see more benefit to it; but it does work well for petrol engines too!

 

Get it done, it's the only way to find out ;)

I'd certainly be interested to try it on my leggy (207k) 530D. I've been through and changed all the filters, tried redex diesel cleaner on it, and whilst it's a lot better it does still feel a bit lethargic, is a bit noisy and absolutely reeks if you stand behind it.. I can't imagine what it smells like under acceleration for the cars behind.

 

There is a Terraclean agent a mere 5 minutes from my office as well. Hmmm....

I'd say at that mileage, you'd really benefit from it!

Interesting, thanks for sharing guys. I think I will give this Terraclean a go, hadn't heard of them until now.

Hi,

 

I'm likely to get a Terraclean done soon too. I need to do some maintenance, bodywork on the car first, then add some modifications and then do the Terraclean. My engine is on around 285,000 miles now and I've got a substantial MPG improvement as it's now a 5 speed manual. I'm hoping there'll be a small but noticeable MPG improvement once cleaned and smoother running and less exit soot from the exhaust would be a bonus!

 

Lots of people are still unsure of such a cleanout, but it's now fairly well known and there's many owners positive responses!

 

Cheers, Dennis!

So do you guys use a fuel injector cleaner additive to the fuel every year in addition to doing the Terraclean every blue moon? Cheers.

I booked my car in for a Terraclean.

Update: Car had a Terraclean today. It took the mechanics about 30 mins to figure out how to get the car to start with the Terraclean fuel supply as hooking it up to the fuel line from under the rear seats didn't provide enough pressure to start the engine. They hooked it up in the end from under the bonnet. Used two large cans of the Terraclean liquid. My car is 16 yrs old and done 60k miles, mainly b-road and town driving. TBH I didn't really notice any increase in power but the engine was idling more quietly than before. I did use a couple of bottles of fuel injector cleaner in the month prior and I think it may have helped a bit, although it's hard to say. I think the most difference was when the cleaner was in the fuel tank, after I'd used up 3/4s of the treated tank, and maybe it acted as a fuel additive to increase the power of the petrol, iono. If I do another Terraclean I think I will wait for more miles to rack up on the clock first.

You say it took the mechanics 30 mins to figure how to get the car to start - did they know what they were doing generally with this process?

I would have to say the main mechanic doing it looked to be relatively new to it, and was being overseen by the co-owner of the garage, who couldn't get it to start from back there either. He got on the phone to BMW apparently to ask them. Once he got the engine started he seemed to know what he was doing. Once started, with the pressure up near maximum, at nearly 40 psi, the job was completed in around 20-30 minutes. They were an official Terraclean agent. If I do it again I might go somewhere else next time.

The thing that always concerns me with things like this is, it's someone else arsing around with the car (if I was you and they couldn't get it going for 30 minutes I would have been gone!) plus what if it upsets the "status quo"? I might be a bit paranoid but I would be certainly wary!

I can't imagine any of these treatments being any different than a pretty strong mix of IPA or Ethanol etc, in which case just getting your injectors cleaned and serviced properly would be far more beneficial.

 

or just dump a few pints of ethanol in the tank.

 

diesels and direct injection petrols seem particularly susceptible to carbon buildup in the inlets, but making the engine suck all this shit up I cannot imagine being any good for the bores and rings, certainly for a diesel engine it would not be my first choice of thing to do as the high pressure pumps and injectors rely on the fuel for lubrication.
