I couldn't believe it! I don't think it would be super detremental, but if we're going to do it, we want to do it right....so I'm going to edit the video to show the ISTA+ portion too.

Hmm, thanks for adding that, it looks like I'm going to have to factor in purchasing ISTA+ now, this is not going to be cheap but still cheaper than the dealers and ISTA+ can be used for other things I suppose.

So 7 litres of oil now.
