My wife last week took her Skoda Fabia 1.2 to the local Skoda dealer for an oil and filter change. When she came home she checked the bill a little more closely than she had at the dealer's. The price of the oil was recorded at £30 for five litres (£6 per litre). I hunted online to find that the oil capacity for this car is 3.4 litres. A difference of 1.6 litres at £6 is equal to £9.60. After contacting the dealer they agreed to let me have the surplus oil. This will result in a round trip of more than 30 miles. I wonder if this "error" is repeated elsewhere? If it is, what a nice little earner.
