I can tell you with absolute certainty that the belt does not degrade AT ALL like those in other cars. Mine went 10,000 km with the *broken belt tensioner * and I only replaced the tensioner because the belt was in perfect condition and still had useful life left. Not a single chip in the oil or filters. It’s true that I follow maintenance to the letter and use the oil specified by the manufacturer.
However, be prepared to open your wallet when you have to change it, because it won’t be less than €1200, as it usually coincides with other maintenance (spark plugs, valve adjustment…). In my case, I do it at home and buy the parts from Honda to avoid problems.
