FTC04 Fuel Tank Catalyst. The one-time treatment for a cleaner engine and permanently low emissions. For engines up to 4000cc.

Added to full tank of petrol which improved performance and CO2 emissions [I think]. Smoother running and small increase in mpg [I think]. Car - 21 year old Landcruiser Colorado 3.4 V6 Petrol with 195,000 on the clock.

Snake oil.....

My jalopy has been hitting 43mpg (aware that doesn't sound too special but its an 11 plate CLS 350d) on my motorway trips and I hit the loud pedal now and again! Acceleration does seem smoother as well. Word of warning - I played safe and got the rascals fitted as part of a service by the garage which was just as well as some manufacturers such as Mercedes have filters in the fuel nozzle and I would have come unstuck if I'd popped them in myself. Anyway, they seem to be of benefit.Oh, final word of warning, don't get them fitted too near to an MOT as initially they get rid of some muck in the engine/exhaust system and will drive emissions up.

The difference in car is unbaleveable more miles pr gallon plus performance

You must be joking a solid piece of metal doesnt do anything. Don't you think car manufacturers would put these in all their cars rather than spending millions on making engines more efficient if they worked e

this is the fourth time i have used this product, brilliant product does exactly as it statesit does take approx 200miles to notice the difference , but it makes big difference ,also protecting your engine in a strong way,
