Vehicle: 2002 VW Golf (German) Engine: 1.4 liter, gasoline 75 hp Odometer: 60k miles / 100k km Fuel consumption: 29-33 MPG / 7-8 liters/100km Oil used: 5W30
I've had to add about 1 liter (1 quart) of oil to my Golf over the last ~1000 miles. Based on my previous experience, this seems quite high. What is the typical oil consumption of this type of vehicle (specs given above)?
The fuel consumption is also a bit higher than I expected for the small engine.
I don't see any oil on the pavement where the car is parked, and the coolant is clean. There is no visible smoke in the exhaust.
On two separate occasions (separated by 4000 km and a few months), the car has begun running rough. Both times the mechanic replaced an ignition coil (different ones) and the associated spark plug.
I was worried that perhaps burning oil was fouling the spark plugs--is this is possibility, or is a succession of failing ignition coils a likely explanation?
