I just bought a used 2013
I just bought a used 2013 Outback and noticed after driving it 1,000 miles that I needed about 1 quart. I came across this site, as well as others, regarding the oil consumption test. I went in for a recall (wiper motor) and addressed this issue. They told me it was "normal" for a car to consume up to a quart per 1,000 miles.
If I'm adding a quart every 1,000 miles, once the 7,500 miles is up for another oil change, I will have added 1 3/4 gallons of oil. In theory, I should never need an oil change again, because every 7,500 miles, I'll have already completely replaced the oil. Even if it was 1 quart every 2,000 miles that would still be almost a full gallon.
After saying this to the dealer, they suggested an oil consumption test. I'm wondering if they'll honor this if it isn't a complete quart after the 1,200 mile mark. Even if they don't, at least I'll never have to worry about another oil change :p
I guess we'll see what happens...
