Exclamation 2012 Impreza Burning Oil

I say burning but I don't know where it goes.

I am new to the thread, but my 2012 impreza needs oil added frequently. I need to start watching exactly how much. I would say a quart every 7,500 miles.

I would love to see an impreza owner log on and say that they don't burn a drop.

Thanks to all who have pointed out that the dealer over fills. I thought they did that but was reluctant to question their expertise.
I will now.

I would argue that adding 1 qt every 7500 miles is not "frequent". In fact, since that's Subaru's recommended oil change interval, it sounds to me like you don't need to add oil at all.

No one likes the thought of their new car burning a quart of oil between changes.
But it sounfs like youre on the far end of the oil consumption scale. I burn a lot more oil than you and am not close to burning enough to get anything replaced.

Did any of your other cars go 7500 miles with out adding oil?

Needs oil frequently? 1 quart every 7,500 miles is not frequent - that is the optimal oil change interval. If you look at the description of severe conditions, a lot of locations/situations actually fit that criteria. That interval is much less than 7,500. I personally think Subaru made a bad decision on making the interval that long on such a light weight oil.

Actually to my knowledge mine has not used a drop. Hard to tell, though, as the dealer overfills it. Next service I will pursue the question of why they overfilled it.

Speaking of dealer service, how does one get out of the maintenance agreement?

Agreed i think every 5k is a good number to stick with

There's no harm in that choice. But if you've looked at the Used Oil Analysis thread, then you've seen the results of my analysis, which showed that my oil had a lot of life left in it at 4500 miles, and that Blackstone recommends I could safely go to a 6500 mile oil change interval.

DISCLAIMER: I use Amsoil OE 0W-20 oil, and don't drive very aggressively. If your oil and driving conditions differ from mine, then you might get different results. I provided my used oil analysis report as an interesting data point, and make no guarantees about the OCI you should use.

What do you guys think about the new Mazda 0w-20 Synthetic? I've heard some good things about it:

http://www.cleanmpg.com/forums/showthread.php?t=45295

http://www.bobistheoilguy.com/forums...Number=2520584

It's a little expensive at $7.95 per quart, but thought it may be worth a try for my next oil change coming up.

I think it will be no different than any other 0w 20 oil. That includes amsoil and mobile 1.

I am also going with a 5k mile interval. My good friend (head Suby tech) suggested between 5k-6k. Since I get free oil changes at my local dealership, I'm going with 5k.

I will now.
I change my own oil, last change was October 30th, with 7000 miles, and now have 9,400 miles with no visible change in oil level. If I overfilled it, it wasn't more than a couple of ounces (I think I poured about 5.4 liters in).

That does not mean it hasn't used a drop, just that it is not burning enough to be noticeable.

There are cars that are burning oil, and cars that are not. There is a problem if you are consuming a liter between changes, no doubt. However you cannot take your experience to mean that all of the new imprezas are burning oil, because the evidence actually points the opposite direction, a small percent are burning, and most are not. At least all the evidence I have seen, based upon the number of cars sold.

Same here with the 5k oil and filter change interval. My driving situation would probably fall under Subaru's definition of "severe", but I feel a 3k interval is a waste of money. I will probably send a sample to Blackstone Labs the next time I change my oil.

Also using AMSOIL OE 0W20.

I'd like to see the results of a uoa from an oil burner running 0w20 subaru oil, and going the reccomended 7500. I've never had oil in my car long enough to worry about uoa's but when that consumption test is over, I'll send off a sample.

Being that Amsoil is such expensive stuff,I'd be curious to see what a 79 year old guy whos getting dealer changes gets for uoa results. So far it looks like even with amsoil and a good non oil burning engine, 7500 miles is pushing it.

Not ALL the imprezas are burning oil. But it says a lot when Consumer Reports has to top theirs off...
And dealers have scripted answers about allowances...

Not all Amsoil is expensive stuff. My Amsoil OE 0W-20 costs $6.10/quart, and no shipping charge because I buy it from a local distributor.

My car is not an oil consumer, so I'm not adding any fresh oil between changes. My Blackstone UOA with almost 5k miles on the oil (and 11k miles on the odometer) resulted in Blackstone telling me I could probably get 7500 miles from the oil, but they recommended using a 6500 OCI just to be safe (and sending them another sample at 6500 so that they could confirm that the oil was still good, which I don't plan to do; instead, I think I'll just use a 6500 mile OCI and leave it at that).

I just paid 5.54/qt after shipping and tax for my amsoil OE. So definitely not expensive stuff

That's about what I pay. Think it's only $4.70/quart before shipping and tax.

Better and cheaper than M1 and shipped to my door within 2 days!

I want to believe that the Amsoil OE is better than Mobil1. But without a Used Oil Analysis from someone running Mobil1, we're all just speculating.

Our Imp hasn't burned a drop yet. It has about 12,000 miles total now i think.

I agree that all new Imprezas do not burn oil. My opinion is that a small percent do burn oil. That is based on my experience.

It is also your *opinion* Zeeper. It is not *evidence*.

You need to learn the difference.

It looks like stevehnm and Zeeper are in agreement then--a small percentage of Imprezas burn oil. I think everyone on this forum agrees that this is true. Nobody is saying that they all burn oil, and nobody is saying that none of them burn oil.

"Small" is a relative term, and only Subaru knows what that number is. It could be 1%, it could be 25%. I believe it is within that range.

We don't know, as we don't have the *evidence*. It does point, however, to a potential variability in their manufacturing process - another feature of which might be excessive fuel consumption, as opposed to excessive oil consumption.
