Hard to believe? But I have clocked more than 200 kms in city, usually it is 180-190+. It is an Xli 2005, converted in March 2008, with original LR Italian kit and original STAP advancer. Stock rims with 185/65/14 tyres. Orginal air and oil filters bought from 3S dealer used with Shell Helix extra (semi-synthetic). CNG filling station Shell I-8, Markaz, filling timings after 11.00 pm. Always switch off engine on red light, if it is more than one minute stop. NOTE: Car just starts on petrol and immediately switches to CNG--not linked with RPMs or distance. AC used is 95%
