[Ciao]

I left the oil for 14 months in my Audi after driving it 3K miles not driven much. After a year with fewer than 5K miles, I changed it and looked brownish. It is a turbo and I use 100% synthetic. I wil never go over 1 year without changing the oil regardless of mileage. I drive my P car less than 2K miles/year and always change the oil 100% synthetic M1 0-40W before storage--6 months in storage.
