Bro complete atleast 3000 KMs before you claim average. The most minimum is 1000Kms, after which the real calculation starts. Before 1000kms, they say don't push car at high speed for a very important reason. It's simple, the engine is not ready, it's not fully nourished and parts of the car are not ready. That's what they do at 1000Kms, they tighten your engine and car parts and make sure your car ready for full potential use. Right now, car is using all the fuel and engine all it can to nourish it self, so the average at this point doesnt matter. Hope you understand
