Not an oil thread .... just an oil change interval question

[peterbaron]

When I first read a test about the Honda in 2013 the magazine listed an 24.000km interval for valve inspection. When I bought a lttle later the bike I saw in the Owners Manual a 12.000km one to my surprise.

What do I do? Make my own decision wether to inspect or not, change or not.

So its up to you....all a little bit confusing, if you not only keep strictly to the manual and read some more 'info'.

Let me restate my original question.
Assuming the normal interval running GN4 SAE 10w/30 (non-synthetic, I think) is 4000 miles, does Honda specify a longer change interval if one were to run their recommended synthetic?

This question you should address to Honda, if service manual does not answer it.
Using synthetic oil does not necessarily mean longer intervals, but it definitely means better engine protection.
Some synthetic oil companies claim longer intervals, but it does not mean Honda approves it
If in deep doubt, strictly follow manufacture service intervals, do not exercise at all at your own, and do not ask others for advice that may influence your decision.
If you want my private opinion which oil is better in this matter: 1-synthetic, 2-semi synthetic/synthetic blend or 3-conventional/regular/mineral , my answer is as indicated 1-2-3....
Each manufacture sets certain standards, which in my understanding is "good minimum"...one can always go above it...
Hope this summary helps you
