I have a 1968 jaguar 240 model and want to know if your 20/50 classic oil would be ok
The jag club recommends valvoline vr1 but this is suitable for high stress/temperatures etc which my car will not be subject to.
Back in the day the recommended oil would have been Castrol or Duckhams.
Your classic oil seems to have good reviews, your opinion would be appreciated. thanks
