    The oil level in my Volkswagen Polo Vivo drops slowly and there is oil in my water bottle

    Volkswagen Volkswagen Advice Volkswagen Polo Volkswagen Polo Advice

    I have a VW Polo Vivo 1.4-litre. I bought the car two months ago and I've seen recently my oil level drops slowly and there is oil in my water bottle.

    Assuming you're looking at the coolant catch-bottle and not the windscreen-washer fluid bottle, this is probably a bad thing. Any time the car's engine coolant can mix with its oil or vice-versa, there's a chance that the cause is a failed head gasket or perhaps even something more serious like a split cylinder bore.

    But don't just assume that any contamination in the coolant is engine oil. It could be something else from another source. Does the engine oil look milky on the dipstick? If it does, then that's almost certainly due to coolant being mixed with it, and that backs up the failed head gasket theory. The other thing I'd like to know is how fast the engine oil level is dropping. Some oil use is normal for a car's engine, so simply watching that level fall over a few thousand kilometres and presuming it's going into the coolant is a long shot to say the least. It sounds like you need to have the car's cooling system pressure tested and the engine compression tested. That's the best way to put and end to the guessing game.

    By the way, is your car a South African-bult VW? From what I can gather only South Africa got a model called the Polo Vivo which featured a few country-specific features and details and was very well received by buyers in that part of the world.
