Hi all

Just been quoted £130 minus 10% (£117) for SIDC membership for 6 month/7500 mile service. Oil to be used by dealer is Castrol Magnatec. I requested that they use a fully synthetic oil but was told that Subaru do not recommend one. I believe that Subaru are affiliated with Shell (?) and that Shell super helix (fully synthetic) would therefore be suitable, and not effect the warranty. I also believe that the viscosity of this meets the required specification. Subaru's technical department gave me the impression that the viscosity was far and above the most important factor.

I know this has been covered a million and one times, but IS shell fully synthetic OK to use and DOES it meet the correct viscosity level?

Any comments appreciated

 

Ernie,

Whether it does or not (and it probably does), why concern yourself anyway?
Subarus work best on Silkolene, pure and simple. Few more expensive, none better.

I would check with your dealer - Subaru DO recommend an oil for the Impreza - Mobil 1 5W-40. This is specially formulated for Subaru and made available to the dealers (not available to the general public).
