Ha Ha. I was waiting for that!

Well I tried real hard to get some Shell Corena P100 or BP RCR100 but the least amount I could find to buy was 20L from Blackwoods.
Emails to Shell and BP customer service to try an track down sellers of small amounts (I needed just a couple of litres) produced zero replies after one week.
Phone calls to shell and BP got me through to a couple of bimbos who could tell me where my nearest Sevice stations were but I had already phoned them and got nowhere, in fact some were downright rude.

Stores like Autobahn, Supercheapauto, Repco etc have compressor oil and while it says it is ISO rated it does not say what grade it is (I was after ISO 100 rating which is apparently equivalent SAE30 but it must not have any standard engine oil additives in it)

H&F had Pilotair ISO 100 compressor oil for $22/L and only sell it in 1L containers but in the end I bought the same thing from the local Pilotair agent for $10/L and they also sell it in 1/2/4L containers.

Anyway change the oil on the Clisby - all good there.

Next I decided to change the oil on the trusty old Bunnings/Trade Air 2.5HP jobbie (it has done about 8 years for me and I still can't kill it) since I had not changed the oil in if for about 3 years.

After warming it it with 3 complete cycles I drained the oil and it was like black treacle and only about 3/4 of a cup of oil came out
What was weird was the sight glass showed that there was oil was half way up the sight glass so why was there so little oil in there?
Closer inspection showed that what was on the sight glass was just a sludge film that just made it look like it had oil in it.
Anyway - fixed a couple of leaks, tightened up a couple of loose nuts and bolts and it's now over at my son's shed to see if he can break it.
