Thought I would take a punt and take the XJS to get Terracleaned. I am sitting in the garage now watching it get done.

Will be interesting to see if it makes any noticeable difference to the running or performance.

Anyone else had it done?

Well I have had a good result, car is definitely smoother through the rev range and feels a bit stronger. Before and after emissions test show a noticeable improvement, so the engine is obviously running a lot cleaner. It will be interesting to see if MPG has improved, and I will be driving a lot over the weekend so I will get back with anything else I notice.

The guys at Autolube in Letchworth were great with the car and were showing me around the kit whilst the clean was taking place and talking me through it. For the price it is nice I can feel an improvement and it is satisfying to know the car is now running cleaner and the injection system has had a good flush through.

Is that really just a clean? Theres a pretty big shift in mixture between those two results- I don't know the injection system on your car, but could it of had a "little tweak" during the cleaning?

Lambda reading suggests its running leaner than it was, as it is IIRC it would fail an MOT test on Lambda.

The sceptic in me says they've just hung the sniffer out of the exhaust a bit.

Given o2 is also higher....an air leak of some sort does sound very possible.

That second reading is just inside the lambda limit for mot , I'd normally see that on a car with a exhaust leak . Co from the before test is about right give the lower lambda reading .

I see this a lot on mot tests and holding the rpm at 4k for a minute usually has the same results as the before and after readings from the terra clean

I'm sorry but logic mandates this is all nonsense and snake oil. If injectors were partially blocked they would inject insufficient fuel and cause a lean mixture although engines with closed loop lambda would just correct for this in the fuel trims. Cleaning injectors can't magically turn a rich mixture into a lean one even if the cleaning actually did anything.

Bit rich to call it snake oil just from the emissions readings, just take a look online and have a look at all of the positive reports on different forums, plus the improved running that I can personally feel in my car.

I was not saying that it is just an injector cleaner, it 'apparently' is a lot more than that, just i don't know what it has done to my car to make it run smoother.

Either the pipe wasn't up its chuff properely or it's now running (too) lean for a V12 h.e lump.
Personally wouldn't have that stuff near any of my cars.

Hmm Zero RPM in both cases - I'd be concerned at those emissions with a non-running engine laugh

Never seen an rpm reading on an emissions print out before.

How would the machine get it?

There is no electrical/ignition connection to the machine.

Most gas analysers have other connections as well as the sample pipe, including an rpm clamp (that hooks around a ht lead) and oil temp probe.

I'm still waiting after many years for someone to tell me what solvent it is in Terraclean which dissolves carbon in the intakes? Neither I nor chemistry in general know of of any Carbon solvents. The stuff is certainly good a dissolving money though.

There are many solvents that along with manual labour...ie brushes etc will clean them off.

However, if adding these to the fuel, which never sees the dirtiest area of the intake...it would take a small miracle to actually clean them

Manual labour yes, solvents for carbon? Name one.
