Fully synthetic or not.

Interesting.

I have used Honda GN4 10w 30, changed every 4,000 miles (per Honda's spec), for 76,000+ miles. Starts and runs fine, sounds quiet, shifts smoothly, no clutch slippage.

I have run GN4 10W30 changed every 8,000 miles (per Honda's spec) for 56,000+ miles in my NC 750. Again, starts and runs fine, sounds quiet, shifts smoothly, no DCT clutch slippage.

If you are changing oil every 4,000 miles I don't see where synthetic offers any benefit, but you should certainly run whatever oil makes you feel comfortable.

I've also used Honda dino oil every 4000 miles. Over 155,000 miles on it now. Never had a problem.....
