SlickSpur Posted February 28, 2013 Share Posted February 28, 2013 This seems like a simple question/answer. Am I burning oil? I'd just check the dipstick and see where the oil line is. I went to the dealership for front/rear differential fluid change. They told me my oil was dirty and needed changing (I changed it 2k miles ago ), and they also told me I had burned 3/4 to 1 qt of oil. When I got home, I checked the dipstick, and it was just barely below F. I was confused how this reading could signify I was down that much oil (it wouldn't). I added a little to be cautious. The dealership told me they'd top it off for me, I told them not to, so I'm assuming it's not from them doing that. If I was down a qt, the dipstik would be reading by the "L", correct?

orndog Posted February 28, 2013 Share Posted February 28, 2013 Sounds like you need a new dealer. Unless your oil was visibly tar-like nobody should ever tell you that your oil was "dirty and needed changing". Link to comment Share on other sites More sharing options...
BoozeRS05 Posted February 28, 2013 Share Posted February 28, 2013 Down a quart would be obvious on the dipstick. So unless they added oil anyway/already before they told you, you're fine. I agree though, time to find a good independent shop.

apexi Posted March 1, 2013 Share Posted March 1, 2013 I wouldn't distrust the dealer yet. Yes, down a quart would read around the low mark on the dipstick, but our dipsticks are temperamental from my experience. How long did you let the car sit before checking your oil? The tech might've topped you off anyways even though you said not to. Obviously theres lots of reasons for consumption. I always thought my car was consuming oil through the pcv system. But I didn't really realize until recently how common it is on our cars for the spark plug tube gaskets to go, or at least it appears common after searching. Found that out when I went to do my plugs the other day Link to comment Share on other sites More sharing options...
AZP Installs Posted March 2, 2013 Share Posted March 2, 2013 On the Boxer engines it's fairly common for the Valve Cover Gaskets and Spark-plug Gaskets to go over time although we haven't seen this as a major issue really on Subies overall. I would say when you check/replace your plugs every 30 or 60k miles to check those gaskets. -Mike Paisan http://www.pbase.com/paisan/image/91072632.jpg http://www.pbase.com/paisan/image/145749898/original.jpg http://www.pbase.com/paisan/image/133406601.jpg http://www.whiteline.com.au/images/logos/perf1.jpg 11+ Years Maintaining, Modifying and Educating TriState Subaru Enthusiasts.

lee07 Posted March 6, 2013 Share Posted March 6, 2013 No, ok maybe a little but it's normal, 2000k miles it'll burn some. You're fine Link to comment Share on other sites More sharing options...

Max Capacity Posted March 6, 2013 Share Posted March 6, 2013 OP, you need to start checking your oil once a week, after the car has sat on level ground for a long time, like 4+ hours. I do mine after I come out from work. Top it off as needed. We went through this the other day. These car use oil at different rates. I can drive 1500 miles and not use any oil, then the next 500 miles the level is down a bit. Some times on the drive to VT it will use oil, next weekend it won't. I'll check it and top it off here went I leave work today and then again Saturday after skiing in the parking lot at Okemo. Last weekend up and back it didn't use any oil. The previous weekend it used a little on the drive up to VT. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

SlickSpur Posted March 7, 2013 Author Share Posted March 7, 2013 I assume the method to knowing how much oil should be added back in is just by adding a little, rechecking dipstick, adding a little more, rechecking dipstick, until at F? I'd imagine after a few times you can get pretty good at approximating. Link to comment Share on other sites More sharing options...
imbastos Posted March 8, 2013 Share Posted March 8, 2013 OP, you need to start checking your oil once a week, after the car has sat on level ground for a long time, like 4+ hours. I do mine after I come out from work. +1 on letting it sit for awhile. I thought I was low after checking my car right after driving. topped it off, and checked again the next morning. I was way over and had to drain some out. Link to comment Share on other sites More sharing options...
