Excellent, delivered on time

Great product. Delivered on time. Will buy again.

Works well, just a bit expensive. Hence the 4 and not 5 stars.Had a small increase in mpg , and ran smoother. But you could just use any injector cleaner to get that result, to be fair.

What can I say, did the job it was purchased for.Yes, better fuel economy and quieter engine.

At first inspection i was impressed with the product size.I have found that this product has had a positive impact on performance figures for my high mileage car.Mpg improved and overall engine performance data improved on my obd 2 system data graph.It is something that is recommended as a repeated application not as a one off and I will do it every 3 months I feel that this will keep my car running smoothly.The price i paid seems fair for the outcome I have had and I do not have any criticism of this product.I am giving this 5 stars.

Can't comment.Hoped it woul clear a 'Phantom' Engine malfunction caption but didn't.Too soon to see if any other benefits

I put this stuff into my fuel tank every 6 months from a recommendation from a mechanic some years ago. I drive a 2005 diesel engined jeep cherokee with 150k miles on the clock. Every year at the Mot the emissions test shows emissions at less than half the max allowed. I can't say for sure how much is due to cataclean, but in my view it seems to help.
