    Default Mehran 94 Reducing Engine Oil

    Dear All,

    I just overhaul complete engine of my mehran 03 months later;
    • Bore and Sleeves from a reputed workshop
    • Japani Piston and Rings
    • Complete Head valves, cam bush, valves seat etc
    • even new clutch plates
    • 800 Km running on Petrol
    • No oil leakage at all
    means complete from all respects.

    Now i have driven my car around 9000 km
    and em using Caltex Havoline (high grade) engine oil
    i used to change oil after every 3000 km

    after the completion of first 6000km at the time of 2nd oil change the oil level was OK
    but now after completion of 9000 km at the time of 3rd oil change i observed that the oil level was reduced by 0.5 Ltr.

    Experts tell me that what can be the reason of oil reducing???????

    there was a slight difference in mode of driving that first 6000km was mostly driven localy on average speed, and last 3000km was mostly long run high speed on motorway.

    havoline is a 10W30, it's probably having a hard time coping with the heat nowdays so is burning off a little oil at a time (flashing).

    why are you using havoline? because it is the most expensive? ads on TV?

    there are more suitable oils out there for your application in that price range.

    check the engine seals and oil change cap.... it is becuse of heat for sure. heat may have caused the engine tapet seals to deform slight and driving fast means more pressure in the engine and so on engine oil.

    Well newly rebuilt engine should not reduce oil on 10-30 too much. I also got the rebuilt and using petromin and no oil reducing. Not even a drop in this heat with ac.
    Speed costs money, how fast can you afford to go.

    the mehran engine uses engine oil - 0.5 litre per 1500 kms is normal.

    Please be sure that your engine is coming upto normal operating temperature at all times - that means the temp needle sits in the middle and not asleep at "C"
