Doing my second oil consumption test this week. Down a quart after 3200 miles. I'm frustrated that Subaru finds it acceptable for a car to use a quart every 3600 miles. (1/3 qt every 1200 mi.) when the recommended oil change frequency is 7500 mi. And why do some foresters not use oil and others do? That is a quality control problem. Subaru has become way popular in the last several years and must have ramped up production. Maybe they need to funnel some extra resources into QC and not just spit out an inconsistent product.
This is my second Subaru Forester (my 2013 forester with 24k miles got totaled after someone ran into the back of me). I noticed the oil consumption issue on my 2013 forester, it would go thru a quart of oil every 5,000 miles. I switched to 5W20 and it solved the problem (still a pain). My 2014 does not burn any oil at all and I use the recommended 0W20 full synthetic. The big selling point for me on these cars is how well they drive in the mountains on snow and ice. I don't have a scientific way to validate my observation but I drive a lot in the mountains and I can tell you that compared to my 4WD Honda Element (which I love), the Forester is head and shoulders better when the road conditions deteriorate.
I purchased a 2014 Forester in the end May of 2015 (19,000 miles). After driving for about 1200 miles the low oil light came on. The dealership topped of the oil 4 times before they would do the oil consumption test. After the test they replaced my engine(so they say). After driving the new engine for a week, the low oil light came on. Topped off oil again. Consumption test again tomorrow. 7 months of owning this vehicle and over 20 hours of waiting in the waiting room. I want my 2006 Nissan back!
I bought the forester in Jan 15 it had 23,000 miles on it. I drive 104 miles round trip to work each day. I have 47,000 on the suv now and just lately I have noticed it is drinking oil. After a fresh oil change I find that the oil light comes on after about 2,000 miles and I have to add a quart. I put the recommend synthetic oil in about every 6-8,000 miles. I have been in the car business for 40+ years and have always driven newer cars I have never had to add any oil. This is definitely a problem. I bought the Subaru because I thought it would be a reliable car,but now I,m not so sure. I'm going to contact the dealer and see what they do. Stay tuned.
