I have a MY98 Terzo...had the car for 5 weeks now, i'm not sure when the last oil change was done on it,i will be doind a full oil change, the question is... what type of oil to use??

We confidently phoned the local Subaru dealer who informs us that on all MY98 they used fully synthetic oil and on the newer models they use semi-synthetic.
They informed us that if we do a partial oil change we had to go through the service history etc etc to find out exactly what oil to use...and if we do a full oil change they THINK/recommend semi-synthetic?

No need for main dealer to do the oil change as my m8 owns a garage and he will supply the oil for nothing! Good m8 eh?! lol

Fully synthetic is the way to go, however once you make the change you should never go back.

 

MY03 uses shell Helix if that helps.
