Good product for petrol engines (better than the Addon by Indian oil). It actually improves the performance and engine smoothness but the results can be observed after the second or third time of refueling. Considering the mileage, as it depends on the driving and the traffic condition, with octane booster engines feels to be responsive and churns decent mileage depending on the conditions.Overall a good product!!
