Should I be using a fully synthetic oil in my auto conversion engine?

[Guest rocketdriver]

A friend and I are importing 2 aircraft, one with a Suburu motor and the other with a GM Saturn motor. Both engines have been drained prior to shipment and obviously I want to "wet their insides" as soon as possible after thay arrive.

 

As both engines are derived from modern automobile engines, should I be using synthetic oil in them?

I would.

my 2 bobs..................from chap who rebuilds them............use the blended oil

 

( mineral / synthetic combo ) absolutely the better choice.

And my 20c worth - my Subaru thrives on Castrol Magnatec, a semi-synthetic, ie a blended oil. The advantage is that it is much cheaper than a full synthetic, which MAY be better. Horses for courses?
