750 F1 - Oil Equivalent To Castrol Gtx2

  1. I know oils have been a much discussed issue, so apologies if this has been answered before.

    I have looked in the official Ducati workshop manual for my newly acquired 750F1. It states the engine oil should be Castrol GTX2 - turbo tested - SAE 20W/50 or equivalent. As its a 1986 engine I'm guessing this has long been out of production, and a google search reveals no useful information. It is clearly different from Castrol GTX, but does anybody know what it was?
    The current Castrol website reveals;
    Castrol recommends for your Ducati 750 (1985-2002)
    Power 1 Racing 4T 10W-40

    Should I go for that, or a 20W/50 and if so what grade?
  2. Would you be happy with 1986 tyres? Oils have come a long way in 30 years.
    I use 5W40 in my 1967 250 mk3.

  3. I use Silkolene PRO 4 10W-40 XP in my 1982 Pantah 500. It is basically the same engine as your 750F1 which is much the same as all the other belt Ducatis right through the 90's. In fact, apart from the Panigale and V4, they still haven't changed much.
