2013 Honda CBR600F ABS – 20,700 miles.

I had a full service carried out at 19,200 miles, including oil, oil filter and spark plugs. The bike was filled with Motul 7100 10W-40.

You can imagine my surprise when I randomly checked the oil level yesterday and found it was almost non-existent in the sight glass. There was only the tiniest smear of oil visible, well below the minimum mark. I ride it quite hard, but surely burning through that much oil in 1500 miles is a bit excessive?

I topped it up with around 350ml to bring it back to the MAX mark.

On further inspection, I noticed what appears to be an oil leak on the left-hand side of the engine, around the base of the cylinder block/crankcase area (some photos below).

The bike runs perfectly, doesn't smoke, and I've never noticed any oil spots where it's parked.

Has anyone seen a leak in this area before on a CBR600F/CB600F/Hornet engine?

Any common causes I should be looking at before I take it further?

2013 CBR600F. I have this stuff in the shed:

It's probably at least 5 years old, but the container is sealed.

Am I ok to use it?

The label doesn't say anything about they type or if it has silicate inhibitors.

Manual says:

> Use only high quality ethylene glycol antifreeze that contains corrosion protection
> inhibitors specifically recommended for use in aluminium engines. (SEE THE LABEL ON THE ANTIFREEZE CONTAINER). > > Using coolant with silicate inhibitors can cause premature wear of the water pump seals or plugging of the radiator passages.

Thanks in advance! :)
