I've just booked first service for wrx with main dealer. I said I would be bringing Mobil 1 oil, they said Subaru don't recommend any fully synthetic oil, they use magnatec semi-synthetic. Any suggestions please?

 

I currently use mobil 1 motorsport fully synthetic. Power Engineering used to use this but now use Shell Helix fully synthetic, can purchase the latter from Shell petrol stations.

 

My dealer uses Mobil 1 5/40 fully synthetic which is made by Mobil especially for Subaru.

 

If it's an older car use thicker oil 15w 40, also subaru engines don't like thin oils, but do use a performance oil.

 

Best I`ve used yet in the scoob is castrol RS.
Even good on track days IMHO.

i had this dilemer so i went to my local subaru garage and got the 10w 40 silkolene fully synthetic oil supposed to be good

 

Silkolene Pro S in my RA.

 

Most people use the following fully synthetic oils

1. Mobil1 Motorsport 15w50
2. Motul 15w50
3. Castrol RS 10w60

Silkolene Pro S 10W50............

Thanks for all the replies, in the end went for mobil 1 15/50.

I thought the Shell Ultra Helix FSynth was too thin - being 5-35 ?

Whats with the change of mind ?
