Google says "For a Honda GX120 engine, you should use SAE 10W-30 oil
with an API SG rating (or better) for general use..."
Bunnings has plenty of 10W-30 oil of various API ratings.. ie:
https://www.bunnings.com.au/valvoline-power-armour-1l-10-w30-4-stroke-oil_p3370345
which has a "SJ" rating.
I presume a SJ rating is better than a SG rating?
They do a 4 litre Honda oil that is 10W-30 api SL. I'm leaning towards
that, but i'll never use 4 litres...
Had a win with this pump.. Bunnings˙ $749, The Red Shed $699
Asked Bunnings if they'd do the "beat it by 10%", and to my shock they
did. $629. I no complain... already have the hoses etc... Also bought a
400 litre bladder, a 250l bladder, and a 3/4hp elec pump and pressure switch, and will power it with either a honda 2kva gennie, or a Lithium power pack. All mounted to a pallet, so if we have another incident like last time, just pick it up with the tractor and away we go. When i run
out of water is when I run in the opposite direction. :-)

Yes and as is any later S rating, I think it goes up to P now.

Depends on the price.
I recently did the first oil change on my Grandsons new Kawasaki KLX
140R dirt bike, bike shop only had 4lts of the correct type/grade (has
to be wet clutch compatible) and it cost $100.00 so not cheap, it only
uses 1.3lts per oil change so 3 changes for $100 doesn't seem too bad.
