After constantly getting fed up with my 24l (Oil Free) compressor
running out of air, I have upgraded to a 100L model. But this one needs
oil!

The oil level is a little low in the window and I would like to top it
up, so what oil do I use? Can I use standard 4-stroke motor oil, or do
I need something special?

What about mixing? If I don't know whats already in there, is it 'safe'
to just top it up or should I drain it first?

Any info would be appreciated

Interesting.. I will see what I can find in the UK.. It appears that
they are all synthetic, and rather than take the risk of 'mixing' oils,
I am tempted to drain mine and add all new oil

Many thanks for the info
