"I use this additive regularly on both my vehicles, and can't praise it enough. On my older (10 year old) car especially, this keeps it running like brand new. I have never had the fuel injectors or any part of the fuel system on the car cleaned by a mechanic, and yet I still get the same fuel economy and performance as when the car was new. In both my cars there is an actual noticeable improvement in power after using this. I fully intend to keep using this on my vehicles - can't recommend enough. It also regularly goes on sale if you keep an eye on the Canadian Tire flyer."

Awsome Product

Date:September 25, 2010

"This additive is great, I ran my Honda Accord w/O2 sensor burned out for about 2-3 months, then my car started jerking. I poured in a bottle of this and boy my car's fuel system is like new again. But this thing will make gas consumed more while the thing is in the tank.
I got 393 with this thing in tank and w/ O2 sensor burned out. Now I get 471+ with after this and O2 sensor new again. (On a full tank.)
Great product. I'm going to use this every 6 months now."

Incredible product!

Date:January 26, 2009

"I normally just buy the injector cleaner for my car but came across this product the other day and figured why not. I tossed a bottle in my 97 Cavalier 2.2L with 286,000kms on it and W O W !!!!! I cannot believe the way my car drives now. No more rought idle, starts up easier and there is POWER like you wouldnt believe. I just came back from a quick trip to Hamilton from London and my car has never handled so well on the highway - there was POWER to spare - acceleration is improved 100%, the sound of the engine has improved 100% .... this must be what the car was like brand new.

I am now going to be religious to throw some in the tank every 3000 kms or so."
