ENERG THE BEST IN THE RACE G1 Force HD 15W40 API CK-4 Synthetic Engine Oil for Car (3.5 L)

I have used this oil in our maruti dzire diesel. Happy with the performance

I was very excited buying this oil. After oil is replaced, mileage has been dropped by ~5kmpl. The oil might be good, Its the only oil in the market available witth CK4 grade satisfying the BS VI norms. However, unfortunately, it didn't suite for my diesel renault pulse. I checked the product suitability from the notes before ordering this oil. I expected increase in mileage but surprisingly its dropping by 5kmpl which is very significant. I think the company should give clear notes for which car models this oil will be suitable.I am not saying don't buy this oil, but enaure it will suite your engine before ordering.
