I had the same dealer oil analysis done on my 2008 Tribeca. The car had about 12,000 miles at the time. It took great effort to find a dealer that would agree to do the analysis. They claimed 1qt for 1000 miles is normal for Tribeca's. I spoke to four different dealers before I found one that seemed honest.
The first time the dealer topped it off after 1000 miles, they said they put in .8qts with the oil level on the dipstick at the bottom of the E hole. When I checked the dipstick it was overfilled by about 1/2 a qt. I took the car back and they removed the extra oil. I brought it back after 1000 miles again. They added a 1qt. but when I checked it was overfilled again. I asked if overfilling was their technique to disprove an oil consumption issue. I did this four times in total. Only once did they not overfill it. Then they agreed to do the wet/dry compression test. It came back normal. 125-135psi per cylinder. I was then told that 1qt per 1000 miles was acceptable and that usage had to be over 1qt per 1000 miles. SOA and Zone/Area rep confirmed this and stood behind the dealer.
When I picked up the car the dealer wrote on the Repair Order that I had tampered with the test and was purposely draining out the oil between each 1000 miles. I was horrified and asked the dealer why they would write that, yet not say anything about it to me in person. The dealer said they had marked the drain nut with a plastic ring but it was missing when I brought the car on the last test. I reminded the dealer that I had a quick release valve not a drain nut, and perhaps their plastic ring fell off?
The car now has 28,000 miles on it and it drinks oil like water. No dealer will touch it. The only theory that has been given to me is that I probably did not break the car in hard enough and that resulted in cylinder glazing. I've owned a lot of cars and none of them use a qt every 1000 miles. I hate adding oil every week. I despise Subaru and will never own another one. It bugs me so much, that sometimes I'm tempted to pay an independent shop to re-hone the cylinders and install new rings. I've read oil consumption without smoke can only be via the EGR valve or cylinder consumption. But the $4-6000 I have been quoted is not worth it. That would buy a lot of oil.
Cars use oil and I've read boxer engines use more, but most Tribeca owners I talk too don't have this problem. I guess my Tribeca is defective and I'm stuck with it. My stomach sours every time I lay eyes on that car.

That car is still under warranty. Raise hell or bring suit against the company, and I'm sure they will do something about it.
It is NOT normal. I have owned four Subaru's and not a one used oil. Well, okay, the '96 with 220,000 miles on it would drink maybe a pint every 1000 miles, but that was a gradual progression over many, many miles.

Update, after arguing with the service manager, I got the general manager to approve a compression test. They showed me the results and every thing was in SOA guidelines 185- 215psi. Anything below 164psi is bad. Of course they performed the test with out a load and just crank the engine to 350rpm. Just because their test passed does not mean that the car is not burning oil, especially at interstate speeds or when the car is pulling something.
If your car ia an H6, I would definitely take it back to the dealer if it check out 125-135 psi. Also your car engine is under warranty for 5 years or 50,000 miles. There can be some bad engines out there, I don't think SOA is that perfect in producing an engine that is trouble free. Maybe they are aware of the problem and it would cost the company too much to recall all of the H6 and fix the problem.
I just don't trust there test procedures. Four days prior, my battery went dead and had to have my son jump start it. Took it down the next day and they performed their load test and showed me the results, everything was up to standard. Made me look like a fool and they where kind of smug and "see there is nothing wrong" attitude. The next day the car would not start again, this time I called there roadside service to jump start it. The next day it did the same thing, this time roadside hauled it down to Subaru to fix. When I picked it up they were very surprised that there test did not determine it was a bad battery. So don't believe everything they tell you, research it.
What kind of oil do you use, I change my own to Castro 5w-30 with a top of the line Fran filter.

For the first 20,000 miles I used 5W-30. Tried Castrol, Mobil 1, and Valvoline. Mobil 1 burned the fastest.
Since then I have also used 10W-30 and tried a 20W-50 in the summer. That helped, but I know it puts extra stress on the oil pump.
I was not aware the compression test numbers should be 185-215psi. They told me 125-135 was the normal range and everyone else (SOA, other dealers etc.) I spoke to at Subaru confirmed that.
I could not find the compression numbers in the technical manual either. I would need some sort of official supporting documentation or the dealer is not going to touch it.

The values for the compression was a printed out on the results of the compression test and it listed the SOA range for the test, I have a copy but don't know how to show it on the forum. If you want to send me your email I'll attach the printout of my test with their range.

The Dealer only gave me the compression results on their own Repair Order so I could never see the comparison. I asked for the results, but they said the Repair Order was the only result they had.
Mistyone1 if you wanted to email me your copy that would be very beneficial. I could not find a way to email you via this site, but my email address is public if you click on my screen name.

The EZ30 had been reliable so I'm not surprised if a small, local dealer had not seen that issue on that engine yet. But they should be able to talk to their regional techs and get some help, no?
They say spark or fuel, so add the ignition coil and ignition wires (does that model have 'em?) to your check list.

#83 of 97 shudders going up hills
Apr 12, 2010 (4:40 pm)
I just bought a 2007 Tribeca with 30,000 miles. A couple days after we had it I drove it up a long (200 yard) hill and noticed that it shudders slightly on the way up. It is smooth as can be under any other conditions. Any thoughts on what this could be. Thanks.
