Hi All,

Got the brand new Forester X 2.5litre MY06 ... and the book obviously says I should check the oil regularly during running in ... and I should of course only ever use the Subaru branded top-up bottles.

 

Could someone please tell me which regular, commercially available oil is best ... that I can pick up at any normal Autobarn, Service Station, Cars Plus etc.? I'm in the Sydney metropolitan area in Australia.

 

The car has a Castrol sticker on it so I'm guessing it may have something of theirs in it currently?

 

Thanks in advance.

Mobil 1, 5W-50 or 5W-40.

 

You can elect to use 5W-30 as your handbook probably suggests, but that stuff is thin and has a tendency to burn off - therefore the need to check the level often. They factory fill modern cars with this watery oil to reduce fuel consumption...

 

Other oils I wouldn't mind using:

 

Castrol RS in 0W-40 weight, Castrol Magnatec 5W-40.

 

 

I bet the present oil in there is Castrol SLX 0W-30

I guarantee you it isn't. SLX was discontinued in Australia years ago.

 

The oil dealers use is Castrol Magnatec FM 10W-30 (a workshop oil, unavailable in retail outlets).

 

There's no need to run a xW-40 or xW-50 in a new engine requiring a 5W-30 or 10W-30, especially during the warranty period.

 

Dingbat, if you want "the best", in a xW-30, I assume you mean synthetic, which means your choice is Mobil 1 10W-30, Motul 8100 EcoEnergy 5W-30, Motul 300V 5W-30, or Redline 5W-30 or 10W-30.

 

Other non-synthetic choices are Castrol Formula R 5W-30, or Penzoil or Caltex Havoline 10W-30.

Ok, didna know about SLX's fate down under.

 

 

On the Motul 300V: Make sure you get the stuff for car engines. The bike stuff has EP additives to deal with wet clutches.

Thanks for that people. All good advice.

 

Took the new beast for a run over the weekend. On the punt over the river, 50km of dirt and gravel, then winding backroads along the coast to get home ... With a stop for lunch and to stock up on supplies at the vineyards.

 

Just a taste of things to come and a good start to the running-in period. Must get it into low range for a bit too. Roll on Friday!

 

Cheers all!
