Cough cough,........... an oil question

[FatAl]

is the Harley oil not fully syth now adays, so maybe too good for an old air cooled engne

as far as I know HD do a mineral 20/50 and a synthetic 20/50, a lot of independent Harley shops sell REV TECH american brand 20/50, which is high spec, decent quality stuff.


I can supply high spec semi synth 20/50 to forum members in the northwest, collection only, £14 for four litres.
