My new Subaru Forester used oil like I was a Saudi prince. I had a new engine installed which I did not have long enough to know if it was using oil or not as the dealer ruined that engine. Now on the 3rd engine this year but have not had it long enough to know if it uses oil or not. I did have another 15 Forester loaner for several weeks and it did not seem to use oil for the 1,500 miles I drove it.

If you decide to go ahead and buy one be aware that these cars require 0W-20 synthetic oil. Keep track of the oil use and write down all the oil you add and the mileage. Document everything and if it uses more than one quart in 3,600 miles take it into a Subaru dealer and demand an oil consumption test.

All newer motors run just fine on 10w30/40 oil...preferably dino. Remember that horizontally opposed geometries have components sitting IN their oil baths, so splashing inherent in very low viscosity lubricants is NOT the concern as it is in a vertically- stacked motor. I suspect they spec 0W just for the hope of rounding up that extra 0.1 mpg on fuel consumption tests.In VERY cold climates 5w30 is advised, with returning to 10w in warmer seasons. Older motors running wet diapers or flooding past spark plug seals should use 20w50 in the summer and add a bottle of seal conditioner to stem seepage. Turbo users are the only exception...in which case you are REALLY out there on your own!

According to the dealers I have talked to, new Subaru's may not idle properly with heavier oil in cold weather conditions due to tight clearances.

We're not talking 20w below 10F (molasses) here. Just use 10w winter and you'll be ok.

I bought my 2015 Legacy 2.5, CVT trans. on 2/2/2015. Changed oil at 5,000 miles, then added another 2,300 miles....7,300 total. NO oil problems. The level on the dipstick hasn't changed.
