9 of the noisy and 8 of the quiet have the NVH so that doesn’t seem to be a cure on it’s own
Of the 2013 or earlier we have 15 noisy, 6 quiet whereas for the 2014 or later it’s 4 noisy and 7 quiet – so maybe continuing the trend for 2014 onwards being more likely to be quiet?
Could those of you with Redline and Lodexol let us know the SAE you used if you have it? There are 2 quiet running on SAE 140 so it might be a fixed, high viscosity oil is the way to go (or not!).
