AOA

hopeall r well.. 2day i travelled frm lhr to mtn on mycity06 just on petrol and observed that the exhaust tail pipe is black from inside,wat can be the reason?

1. Is it consuming some unburnt fuel
2. The car is also on CNG but the air intake was full open forpetrol
3. last cng was run with a narrow air intake opening(even lesser than 50%
4. Last tuning was carried out on computer but not by HONDA dealership

ANYONE who canadvise a good mechanic in MULTAN

change the engine oil and note the oil level, drive the car for 1k kilometers. recheck the oil level after 1k kilometers. if there is a significant reduction in ur car's engine oil level it means that the oil is getting burnt, the other case is that the mixture is not adjusted properly i.e too much fuel is going in the engine in comparison with the oxygen.

btw does the car drop water from the exhaust?

No issues, your car is just running rich on petrol - common for CNG-ed vehicles.
