Hi Red Rider,
Oils.....   There will be a lot of replies to your enquiry.   I have a ST1300 with 176,000km on the dial and have been using "Penrite 10Tenths  Racing 15 15W50 for ages"   It certainly runs quieter and has smoother gear changes than with the stock Honda oil, which is very thin.   Give some different oils a try, and see how she feels and sounds, but make sure that whatever you try is rated for wet clutches.

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.

The important thing is that the oil meets the Honda required spec,
If you go by that then just use everyday car oil which was that was available when the ST1100 was designed in in the late 1980s.

A high detergent oil that exceeds API service classification SE, SF or SG - even cheap black and gold oil exceeds that these days.

Some of us do get temps below zero this time of the year; at least overnight. -2C here overnight for the last week except for last night where we had a heat wave with 1C.

I now use Castrol Active 4T 15W-50. I used to use a 10W-40 but it's not available in their mineral oil; for that I'd have to go to their synthetic at double (almost) the price for no perceived benefit.

Is the 10tenths racing 15 ok for running in eng and gearbox combined.was under the impression it was used just for car engines.

You'll see on the bottle that it's rated for wet clutch motorcycles.

Its a bit of a waste to use a "Racing" grade oil, these bike engines dont race, they will rarely get above 4000 revs
