Had a engine management light come on intermittently. Which Ive been told is either cat or 1 of 4 sensors. Seems ok early days fingers crossed
A good stuff for your car....clears your exhaust system
It just works. Halved the emissions.
Im very pleased with this product and noticed an engine performance increase in all 3 vehicles. I can highly recommend this product now that Ive used it.
The best product on the market
I don't usually rate additives. I had a P0420 - Catalyst System Efficiency Below Threshold (Bank 1).". When correctly sprayed in to the air intake on fast idle, this cleared up the problem after a fault reset. Previously the fault had been re-appearing within 50 miles - several hundred now and it's not come back.
good product
