An oil pump problem isn't going to give you oil loss, just low oil pressure which is unlikely to be an issue.I had the low oil press light illuminate the other day. Checked the quantity and found it was down 1 quart. There has been no previous issues what so ever so ever with oil consumption / low pressure etc. so I was very surprised. Low oil pressure switches are commonly set to 3 psi (as I understand) but 1 quart low should not lead to low pressure warning...really!?
Bought this car new in 2016. Currently has 85000 miles / 145000 kms. I heard that some boxers have a reputation for unusually high oil use but haven't seen that on this car. So I'm scratching my head and soliciting comments. Any known issues with oil pumps...?
Thanks for the input.
Exact same situation for me. Going along just fine with barely any use then like clockwork on every. single. trip through the mountains of WV, VA and NC my oil light would come on, usually in the middle of nowhere, even when I made sure it was full before I left. Passed the oil consumption test 3 times! My dealership ended up just comping me a bottle of oil at every service so I always had extra on hand.In my case, my engine uses almost no oil for thousands of miles... IF I don't drive at high speed for much more than an hour or so at a time on the interstate.
On a long trip, driving all day with a lot of mountain travel and high speed interstate, it can easily go through a quart of 0-20 in 1000 miles.
If you have heard of the Subaru excessive oil use lawsuit and settlement, my car qualified, and I took my car in for the oil consumption test.
Free oil change, level check and return the car in 1,200 miles.
More than 1/3 quart used and the lawsuit settlement remedy was a new short block.
I didn't go on any long trips during the test and there was virtually no oil use.
I assumed this would be the case, but it was a free oil change.
Mine is only at 6k and due for it's first change and it's still full. Most of that is trips to the mountains and high speed highway driving too. Haven't been able to do much else with it other than a few months of commuting last winter.
you're missing the point, there are 2 separate warning lights - red low oil pressure = stop immediately to prevent disaster, and yellow low oil level = add some oil soon. (my '17 Owners Manual does a very poor job of making this clear, however; I don't blame you)Illuminates on pressure, not quantity. Likely in the vicinity of around 1.5-3 psi.
my speculation (delusion?) as the owner of an FA20DIT is that my car was engineered with tougher piston rings, tighter head gaskets, 5W-30 oil, etc. to survive high performance turbo driving, without worrying about the last 1/10th MPG for EPA ratings, while the FB25 non-turbos being 90+% of sales had to have every fuel-economy trick in the book thrown at them to get good-looking numbers. (I've actually had a Subaru dealer wrongly put 5.5 qts of 0W-20 into mine; luckily I caught it on the receipt and they were honest in admitting it was a real mistake not just a typo)Mine is only at 6k and due for it's first change and it's still full. Most of that is trips to the mountains and high speed highway driving too. Haven't been able to do much else with it other than a few months of commuting last winter.
Now in time and with more miles that may change, and with more cold starts (bought last fall), so we'll see. I'm used to topping off Subarus so not a huge concern with me unless the consumption becomes really excessive (more than a qt per 1k). Hopeful they fixed the consumption issues for the latest NA engines. If I have to move to 30 weight oil after 100k or something then that's fine.
I put 40 weight in the 05LGT sedan to keep consumption low and I still have it. It's at 155k miles and going strong at stg 2. Someday it will fail but I cant complain after 15 years with it. Doesn't burn much either. Not like the wagon did. That was a qt per 1k roughly. Depending on how hard I flogged it or how much high speed highway driving it did. Both burned it. Around town it was prob half that.
Good to know they improved the low oil warning design. You didn't want the light to ever come on on the EJ's! Not that I want to test that theory w the new foz, lol.
Interesting to hear that automatics also go through oil with high speed and/or mountain driving. I thought it only affected manuals. I check my oil level every 1000 miles. On long out of town trips I check it every 500 miles. I try to keep the oil level between full and 1/4 below full mark.On a long trip, driving all day with a lot of mountain travel and high speed interstate, it can easily go through a quart of 0-20 in 1000 miles.
Well, of course one would expect that. But a quart or more? In one trip? My first and second Forester never did this, even on the same route which I travel frequently. Didn’t make me enjoy the car less. I just had to be prepared.IMO, It really shouldn’t be too surprising that engines run at length under stress (high rpm, under heavy load, etc.) frequently use more oil in the process than engines under less stress...
