Spent the whole morning at MASS. The Maruti rep did not turn up so I went back home. Then I get a call that he has arrived. Went back to MASS. The car was taken in and milege testing equipment installed. The Maruti rep. apologised for coming late. We took the car for a test. Driver and mechanic in front, works manager, Maruti rep and myself in the back. First tested without AC, almost empty road and steady speed. Car gave 21.1 Kmpl. Reapeated with AC. 15.3 Kmpl. Again they insist that the milege is OK. Maruti rep. said that 13.5-16 is what you can get with AC. I asked him why I was not told that by the sales personnel when I specifically asked them for the milege in normal driving with AC. Then I told him to put an ad in the papers stating the Actual milege. He did not answer. I asked him why he was afraid to do it. After all he had full faith in his product. He also gave the usual crap that milege is not constant etc. etc. I asked why I was getting 16 on the loaner car. The works manager said that the tyres had nitrogen and nitrogen gave 2-3 Km extra milege. Can't beleive he is a qualified engineer. Anyway I told them that I will drive the car for a few days and check and if it is not at least 16, I will be back. BTW during the test they were also giving talks about running in. I told them that modern cars don't need it. They said 10K Kms are required for the engine to give good milege. Why is it not in the manual then.
