Changing the oil...which oil to use?

[TWINRAY]

The world got along without syn oil before it's introduction and those that don't use it need not to be embarrassed and wear a mask so they are not recognized in the store buying it

ps. But if I had a nice new ZO6 in the garage, I'd use Mobil 1

I think John is right. We are beating a dead horse.
