I have an alto vxr 2007. I had it overhauled. Its been more than 1000 km after hauling which u may term as breaking period. The sound of engine is perfect also the pick is normal. But the problem im facing is its giving me really bad fuel average on cng as well as on petrol. I got it tuned from many good cng and petrol mechanics but didnt get it right.
A full cng tank is giving me around 75 km with 50% ac.
A 500 rps petrol gives me 50km only with 50% ac.
Experts plz suggest what should i do?
