Beat Diesels milage as shown by the company is just a hoax. I own an LS model whose milage recorded by the showroom owners as well as by me is just 18 Km/L without AC. It gave the milage 0f 20 Km/L without AC in the begining and after the run of 12000 Kms its average has dropped to just 18 Km/L without AC. Upto 10000 Kms its filter was OK but after that its filter Chocks at every run of 500 Kms.
In this way its uncertain to say whether the car would live to half of its expectations after 30, 000 or 40, 000 Kms run.
