Important Note to Amazon!!!!!
Amazon, I didnโt 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.

Best product of mannol.
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. 2500km review: Even after long and continuous trips where the engine was subjected to high rpm in lower gears in hilly region and even mumbai's almost stand still traffic engine feels very refined, just like new. Even though mileage has been the same of 12km in city and 16/17km on highway, engine idles great and its a pleasure to drive the vehicle.
