I was unaware this had to be injected into the intake system

On the box it says something not too clear and when I asked the seller they said something else and anyway it didn't do any of what it is supposed to fix

Amazon, I didn’t mean to click on the button to investigate Doug c Rosenberg. He did not wrong. I clicked the button by accident something popped up on my phone and I tried to click on that and by mistake clicked his comment. My apologies to Doug c Rosenberg.

Really nice product, used in my 15 year old tata manza petrol as per the guidelines. Engine is now very very quiet and extremely responsive when throttled. It feel like engine breathe easy. No fuse easy to use get results. Now will have to observe how long does the effects last. Highly recommend for high mileage old engines.
