Yesterday I (luckily) checked the oil level on my 22'000 km Legacy (about 14'000 miles) and it came out ...dry. I could empty a full 2 liters in it.
That car was serviced by and according to Subaru and I checked the oil every two or three weeks. First time I needed to add more. How is that possible on a car with such a little mileage? I quickly checked the engine and could find no oil leaks.
The last 3000 km were driven mostly between 30=B0/86F and 37=B0/98F at an average speed of 110kph/68mph some on the German Autobahn at 10.5 L/100 km (27 mpg). Could the heat wave that has hit Europe last week be the explanation?
My other car, a 2.5L V6 mitsubichi needs about 0.5l per 10'000 miles but it has over 100K miles.
