Terraclean?

If my engine was dirty I wouldn't want to risk dislodging crud so that it can move on and block something else.
 
It's a good question, and the answer is that is probably depends on how clean your engine is already. - Obviously if there's no build-up in the inlet manifold of cylinders, then cleaning them achieves nothing.
If they're covered with gummy deposits and baked-on carbon, it probably does a world of good.

Can't say it's something I've ever bothered with myself. - I'd rather spray anything I can see with throttle body cleaner and run the occasional tank of v-power.
 
I had my car done at Rebellion a few months ago. It was dyno'd before and after the difference was 21bhp and 10lb/ft. So worth doing, in my case anyway :-)
 
21hp up? damn

I think it's a good idea, but ideally you would be using either Premium fuels (Shell V-Power / BT Ultimate) or fuel additives (Redex/Forte/Millers) regularly so won't need it.

Clearly if the treatment restored 21bhp then the engine was badly coked-up beforehand, most probably due to long-term use of poor quality fuel.

A well-maintained clean engine should not see any bhp improvement as result of the Terraclean treatment.

I had it done in both my Jeep and my Passat (When I had it.) The difference on both was errr "Interesting" ..

First the Jeep - now its a 2.7CRD driving two axles.. so fuel was kinda on the heavy side.. at around 30 - 32mpg, it has 130k miles on her so I bit the bullet, new auto fluids & filters, Terraclean on the engine, filters & Castrol The Edge and.. pickup is better more responsive and.. 35 -37mpg on a run.. didn't have that before.. so yes, it works better and the oil stays cleaner longer..

Onto the Passat, FSH dealer servicing, 168k miles, feeling a little lack lustre... Terracleaned and many commented that it felt more like a petrol than a diesel, and it could lift its skirts and go, better than before..

My conclusion is that it does work, emissions are lowered, performance is better, engine temp is cooler and over all its good for the car.. so I'd say yes, I'd go for it...
 
Anyone had this done?

Snake oil, or worth doing?

I was also thinking of having this done after seeing it on Wheeler Dealers a while back!

My car has 113k on the clock and as I have only had the car for a year I have no clue how clean the engine is!
 
Since it's a franchise, is there any difference in operators or are they all pretty-much the same?
