Subaru Forester oil consumption

  • By Graham Smith

Q

I recently purchased a Subaru Forester and while I am very pleased with it, I am disappointed with what I hear and read about this model's oil consumption. How much do they consume and why, and what oil do I use to top it up? Surely such a modern engine should not consume much oil?

The oil consumption is a result of the engine design, being horizontally opposed, and it's not limited to Subaru. Oil accumulates in the rings when it's sitting and you'll sometimes see a puff of smoke from the tailpipe on start-up. It's not something to be concerned about if you check the oil on a regular basis, as you should do on all cars. Use the Subaru recommended oil when topping it up. You'll find that in the owner's manual.

  • Subaru has a problem with the 2012 Forester using Engine oil excessively. Was on vacation a couple of weeks ago and decided to check the oil at a fuel stop. Was shocked to find no oil on the dip stick. 6000 miles on the oil change. $18.00 dollars later for Mobil one 0/20wt oil as prescribed. Went to the dealer for a planned oil chg and discussed the issue. Their fix is to add more oil when it’s low.  We traded it in on a Honda CRV this afternoon, No Subaru issues no more.

  • My 2012 Forester has used a quart of expensive oil every 1200 miles. I was told this is “normal”. I guess my 2010 Outback isn’t normal, cause like every other new auto I’ve owned, it doesn’t require oil between changes. Do people really buy into this nonsense?

  • I also have a 2012 Subaru Forester X, I noticed within 3 months of purchase the oil seemed low but I wasn’t totally sure, and on my first trip to Sydney from Melbourne, I called in at Seymour Subaru to make sure everything was OK, I was shocked to discover that the car had already used 1 litre of oil. The Subaru dealer told me the engine was bedding down after running in. It’s now June 2013, I’ve had a service at Christmas and in April topped up the engine with another litre of oil at Doncaster Subaru and now again in June I need to top up again yet another litre of Oil! My last car a 1999 Subaru GX Impreza Hatch never required oil top ups between service intervals. This is extremely disappointing and when I query the Subaru dealer I just get fobbed off with “oh that’s normal for these new boxer engines”. I have searched numerous online forums and discovered this is a common problem with the Forester engines that use the new synthetic OW-20 Oils, apparently the new piston design and poor quality rings are responsible for the high oil consumption.

  • I have a 2012 Forester with about 10,000 miles on it. When first purchased it used a quart of 0W20 about every 3,000 mi. Now it uses a quart about every 1500 mi. The oil change period is 7500 miles. This appears very excessive to me. I am having an oil consumption test done through the dealer. Anyone else have this problem?
