The Big Oil mystery (for me that is...)

[Maurits Jonkergouw]

Hi list,

I would like to know what kind of oil my 1985 CGT KV needs/likes.
Some say 100% synthetic because of the hydraulic lifters, some say
half-synth. and some say 100% mineral because in 1985 there was no
100% synthetic oil available. The manual reads '(Duckhams QXR or
Hypergrade) Multigrade 15W/50 or 20W/50'.

For years now I use the mineral oil in my '85 CGT KV, tried
synthetics before but only got me noisy lifters. I'm just curious to
know what you are using and what you might think of the statement
there was no synthetic oil in the year 1985 and therefor could not be
used for these 'old' engines...
