Oh no, not an oils thread......
There are many discussions on oils, if you have a look around you will find lots of info.
I use Penrite HPR 20 W 60 extra 10 Diesel oil. It has extra zinc in it which is good for the bearing load , a bit of an overkill but it works well. It keeps the noise down in the 1100, and lessens clutch squeal when cold. The important thing is that the oil meets the Honda required spec, the HPR oil exceeds it.
Generally in Oz, we dont require the 10W oils as we dont have temps below zero, but do reach higher temps. Have a look in your hand book, or the maint manual available in the 1300 area and see what oil spec is needed for your climate conditions.
To my mind, high priced synthetic oils arent needed, as we dont have high temp/reving engines, so dont need to spend the extra cash involved. Its better used paying for fuel and coffee.
