[Mgs] 20W50 oil

[Paul Hunt]

Castrol GTX 20W/50 hasn't been available in the UK for dozens of years.  It 
became 15W/50 which was an improvement and fine by me.  However a few years 
ago it changed to 15W/40 which is like water by comparison and had an impact 
on the hot idle oil pressure of the V8 which I didn't like.  Whilst Castrol 
Classic is available in XL 20W/50 (it even comes in the original metal can 
and in gallons) it's pretty expensive.  The other sources of 20W/50 tend to 
be 'no name' brands or aviation grade!
