Check your oil more often. If it needs a quart or two between changes it is not the end of the world.

Try running 5w30 oil.

On my invoices both dealers have always used "OW-20Synthetic Oil" ~ would you explain why changing oil types might help?


Even better would be 10w40 to reduce consumption.


Thicker viscosity both when cold and at temp reduces consumption through loose rings. Again, use 5w30 synth is you have no consumption worries, or 10w40 if consumption is an issue, down to 0F.

Thanks. I have always had the oil changed at dealerships. You'd think they'd advise me with this info. Neither one has ever said anything.


SOA does NOT allow dealerships to stray from their guidelines, even though 5w30 is Subaru's own international spec for viscosity!
