hi guys.my car uses approx 1 litre of oil per 1-1.5k which im told is fine with it being a turbo car.i use the 5-30 that vw suggest but after reading a previous post where people were using different oils so that they dont consume so much id like to do this. main question is what if any are people using and is it safe?i need a top up today so i will start by doing that and next time i service will replace the lot. its an s3. any help would be great guys thanks. daz
