Hi All.
Simple inquiry. Our 2005 and 2012 Outbacks each have the 6 cylinder engine. Each car is over 100,000 miles. I use the Valvoline high mileage synthetic blend motor oil, 5W-30. One reason I use this is because I can run the exact same oil in our 1995 Chevy van - so I only have to stock one kind of oil in the garage. I can also purchase it easily nationwide. My wife puts a lot of highway miles on the 2012, but the 2005 only does about 8-10K per year.
So, how often would you change oil ?
Thanks for the ideas. C
