this is pretty decent avg for liana 1.3. it CAN NOT give 15-16 in local, period. I have 44k kms driven all original Liana 1.3 and it does 10-11 in local and long py 14-15 on GT Road. 15-16 on Motorway. so dont worry about it.or you can swap with m18a like danyal pointed as 1.3 is under powered engine for heavy liana's body, 1.5 or 1.8 will have better power to weight ratio and will deliver better results. what your getting from your 1.3 is perfectly normal.
