Hey thats good news Mr. Bangalore
This time with careful driving my Petrol Innova returned nearly 13kmpl with 30% AC usage. I am sure we can extract around 15kmpl with FFE from Petrol Innova with steady speed like 60-80kmph without AC.
Its really dream machine for people who use rarely and don't care for resale value/FE but need best comfort.
Regards,
Ravi.
