Redex revisited.....

My Saab dealer (yes, they still exist) sent me an email recently offering an engine 'fuel system treatment' for £20. Think I'm going to take them up on it as my car's done 120k, is turbo'd and also had the ECU Hirsched, so there may be more gunked up deposits than normal. Wouldn't bother with a newish car though.

Here's their blurb:

"Certified under stringent testing conditions, our Saab Fuel Treatment has been welcomed by Saab owners across the country for its incredible ability to improve fuel consumption by up to 14%. And, with fuel costs currently exhorbitant, that’s a big step in the right direction towards improved fuel economy. Specifically formulated to combat driveability concerns caused by contamination and the adverse effects of fuel degradation, Saab Fuel Treatment cleans and lubricates the entire fuel system both pre- and post-combustion. Used at every service or when symptoms indicate, it is completely safe for all fuel system components including catalytic converters and oxygen sensors."

Check on Jaguar forums. Couple of threads where injectors have failed after being terracleaned.

Were those diesel cars though? If so, those piezo electric injectors have incredibly fine tolerances, wear with age/use, and generally known to fail anyway, particularly the previous generation Ford TDCi ones (which is the same / similar engine to that used in the Jag diesel?)

Have booked my car in for the Terraclean treatment tomorrow morning....

I don't mind using my car as a guinea pig for OCUK motors :D

(Didn't bother with the £20 Saab offer as they said that it was something they added in the fuel tank which sounds a bit like Redex but more expensive).

The valve head isnt exposed to any of the combustion process, hence it shouldnt be sooty

It's exposed to post combustion gases and residue which is inevitably going to contain some carbon.

If anyone thinks that Redex/Seafoam/Terrclean will magically remove carbon deposits built up over thousands of miles they are sorely mistaken. Try decoking some old valves and you will soon realise just how difficult the carbon deposits are to remove.

Terraclean uses a different process according to the manufacturers. Can't say that I've heard of anything known as 'columbic fractionation' though (and neither has Google) and I can't see how it cleans the catalytic convertor....

After the Terraclean treatment a few weeks ago, I got the dealer to throw in some Forte fuel treatment and a Forte oil treatment in with oil change. No harm in a cleaner internal engine than a dirtier one... :D

Been getting some interesting motorway mpg results (measured from fixed junction to fixed junction with cruise set for whole journey):

London<M1>Leicester - 50mpg (60mph)
London<M4>Bristol - 50mpg (60mph)
London<M4>Bristol - 42mpg (70mph)
London<M40>Oxford - 42mpg (70mph)

All an improvement on the pre-treatment mpg. Not bad for 195bhp petrol car!
