Cataclean Petrol Fuel & Exhaust System Cleaner 500ml

I've been putting this in my tank every three months for a year and I have to say it works really well. My mpg is higher and my emmissions have lowered. All in all a good product.

This product keeps you're car running in good condition and eliminates all the crappie that builds up over time, try it and feel the difference yourself.

Good product

Always a bit doubtful on "magic fluid" but my MR2 1998, was getting tough to get through MOT Emissions. Put a full bottle in a quarter rank, after getting stinking hot, emissions dropped under limit and ..even the low fuel light thats been stuck on, they do this on high mileage and older cars (on mr2s) due to the "stuff" blocking in tank sensor. But this stuff even seemed to clean that out, idles better and lower. Yep plenty of working pixie magic in a bottle.

Good product.

This product worked on my BMW petrol by lowering the emissions by 25%

Excellent product if used as directed a good result should take place as it did for myself.

Always use this great fuel system cleaner. Does what it should and not expensive for good results.

Had the P0420 code pop up - and was prepared to exchange the two catalytic converters (since the truck has over 280,000 kms on the clock). As it just came out of the shop, where a coolant leak into the engine had been fixed, and I read that just a little coolant going through the engine into the exhaust system can cause such cat efficiency errors, I figured giving Cataclean a shot might be worth it, to save a rather costly cat repair (especially in Germany, where getting parts and finding a shop able to work on US cars are always a little challenge). So I ordered Cataclean here (to my surprise it was available in Germany - I knew it from the US before) and followed the instructions: gas tank was just under 1/4 full anyway, so I filled in the entire bottle, and then drove the truck on the freeway (stadt autobahn) for a bunch of miles to and fro, while staying out of overdrive (fairly high revs are recommended for this, but in a V8 it is hard to push over 2,000 rpms). I had expected / hoped for an immediate result, but as I arrived back home, the 'check engine' light was still on -- and I thought, yeah well, it was worth a try. Then corona / covid19 struck, and all my cars stood for several weeks. When I finally got to move the truck again after 4+ weeks, voila! -- the light was gone, and the code cleared itself! Cat efficiency was back to normal. Apparently the effect of Cataclean had to "settle in" for a while. And: the light stayed off; I am writing this review 3 months (17 JUN) after the purchase (13 MAR) and application. It was definitely worthwhile to give it a try.

Ho risolto un problema legato al catalizzatore e sonda lambda, sono molto soddisfatto e incredulo 👍

Lo compré para eliminar el típico error de catalizador con bajo rendimiento P0420 para un Honda Civic mk9. Preferí probarlo primero en un Peugeot 206 1.4. Increíble el resultado, el coche cambió en una sola aplicación! Me animé a usarlo en el otro coche, compré un segundo bote, y no sólo eliminó el error, también fue notable el cambio! Ambos coches estaban en buen estado previamente. Para los que dicen que no funciona, hay que seguir las instrucciones: yo lo usé en ambos coches con menos de un cuarto de tanque de gasolina (previamente había rodado para calentarlos), rodé a un ritmo "alegre" (aceleraciones fuertes, usar un cambio menos de lo que usos normalmente...) por 20-30 mins, cargar gasolina completamente y hecho! Definitivamente agregado a mi lista de mantenimiento anual.

Très satisfait

Followed instructions to the letter but disappointingly the engine light is still on (o2 sensor error). May need to just cough up for the garage!
