Just shy of 300 miles so its maybe a bit sooner than the book says for 1st service but I dont think it makes that much difference nowadays. Anyhow, i had a really good look at the oil in the pan and there were a couple of tiny (and i mean tiny) flakes of metal in there that i was nonetheless pleased to have out. Nothing on the magnetic sump plug at all. Extremely impressed overall at the quality of the engine build but this is a Honda so maybe no suprises there. After much overthinking i opted for a quality semi 10w/40. Engine does sound quieter at idle ticking over. I want to see how it feels on the slightly thicker oil. If it doesnt work out i will drop it back onto the thinner stuff.Honda is known as an engine company, and their quality just keeps improving. The precision of the machining and plating processes means friction has been reduced so much that break-in is a thing of the past, and piston ring/cylinder and crank/rod bearing wear are nearly non-existent.
I would recommend using the recommended stock 10w-30 weight oil, especially in the milder climates in the UK. 10w-40 maybe in the Southwest states during the summer. A heavier weight oil actually causes more heat and friction, since the clearances are smaller.
Honda has for years recommended 5w-20 or 0w-20 oil in their car engines. By contrast, Harley Davidson still recommends 20w-50, and even straight 60 weight in the summer.
