Honda City

Review
This product came free as part of AD servicing package.

Fuel consumption not much difference after application though engine noise was reduced somewhat. Throttle has became more responsive as well.

Might not be the best gauge since vehicle only coming to 2 years.

What I like
Reduced engine noise

Increased throttle response

Funnel attachment for easy application

What I do not like
Priced at SGD$15 per application might be deem pricey for some.

Instructions not clear on whether it is recommended to apply on consecutive pumps. AD SA recommended only to use every 10,000km though.

Review
As soon as i added and mixed with my petrol, noise in the engine was being reduced significantly, along with eliminating almost all vibration while idling. I had also noticed that my car's fuel consumption had slightly improved, and emission of smoke from my exhaust is also being conservatively environment friendly. Side effects aside, I'm now experiencing even better engine performance and throttle response. No more 'heavy' driving!

What I like
Engine noise and vibration is greatly reduced. Engine performance was also being boosted!

What I do not like
Price is bit steep
