    First of all who told you to fill hioctane in your car when not needed your car would smoke like that till hioctane is finished keep filling regular fuel after driving so that your fuel octane no goes down

    Water dropping is usually a sign of overcooling t.valve removed in your car ? Use good old grade api SG,sh,sf oil as your engine is rockeram design

    how would you rate shell oil? Btw ive run my g11 on high octane many times with no problem. The black smoke is usually a sign of bad tuning.

    Its G100 with CB 60 carb engine may b your g11 has efi engine. If black smoke is due to bad tuning then why engine was water dropping on a cold start before filling octane??
    What is the function of t-valve in engine???

    When hydrocarbon burns water is produce no matter what type of hydrocarbon (diesel,petrol,gas,LPG etc) high exhaust temperature make its maintain gasious for m if exhaust gases temperature falls below 100C you would see steam condense in water so seeing water tells nothing at all

    Yes this is helpful. My charade smoking same like 2nd (Black Smoke) a high pressure desi electric fuel pump is installed in engine instead of intank may be this problem is due to that fuel pump.
