    Oil advice A6 C5

    Looking for some advice on the correct oil for my car.
    Its an Audi a6 2.7t c5 shape. Its covered 170k and I want to make sure I'm using the correct oil for my cars age and miles and of course the UK climate LOL. I've just got back from Halfords the staff there told me I should use use 5/30 Fully synthetic but I never trust the word of them usually.

    Which oil do you good people recommend?

    Never ever ever use a semisynthetic or a mineral in your car. You will get great carbonization and it will clog. I live in Sweden and we have a harder climate then you have and at your mileage I'd use the 5w-40 because it's a better oil. My car has done 100k miles and I'm using the 5w-40 and it's great.

    The old saying that the semisynthetic or fully mineral is better for an engine is bs.

    They recommend 5-30 for your engine and you get a free filter using code HOT30

    Use a decent quality fully synthetic oil in 5w40 weight if you can and drop it every 6k or yearly, your cams and turbo will thank you for it !

    I vote for the 5w40 also. It's a great all round oil for sure.
