Honda as a company are always amending , changing service intervals etc. as a result of feedback / learnt knowledge. They have always been far more advanced than the competition in this regard, but of course others learn and adapt.
Honda were the first car company, at considerable expense, many years ago to link in with IBM ( remember them), and put in a system with their dealers /agents workshops to feedback to the factory in Japan, in real time, issues that arose in everyday actual use. This enabled the factory to learn and adapt production so the next cars did not suffer the same fault……forward thinking or what ?
It therefore does not surprise me that they are always making changes and adjustments to servicing items, based on everyday experiences.
