oil problem!! help asap!!

so my 07 lgt goes through oil like beer at a bar. i put the car on jack stands and looked for leaking and found no leaks, drain plug and oil filter were both tight. but for some reason i need to keep filling the damn thing with oil once every three weeks or so.. it never gets completly empty only to the fill mark, but i should be able to go 3500 miles with out worrying about blowing up! so i was wondering if anyone knows of a solution before i take it to a local subaru dealer and pay $$$$$...

HELP PLEASE!!

If you search you should be able to find the answers but since I am here are you running synthetic oil?

what oil are you using?
how many miles do you put on in 3 weeks?
how much do you put in?
try switching to Rotella T6, get a compression check, could be a bad piston, turbo seal, or head gasket if you are losing coolant. or just bring it in for someone to take a look to get a definite answer

and search, its been covered and telling us it uses oil doesnt help cause there multiple problems that can be wrong with it

First, how much oil are you actually adding every 3500 miles? It is not unusual to add about a quart every OCI. That is actually my case.
Even Subaru made a bulletin saying that if you drive your car a bit hard, and also use engine braking, the car will burn some oil. So they advise to check the oil level regularly and add a little if necessary.

Oil usage, I never heard of that....doesn't someone's sig say to check your oil and top it off as needed. These things use oil.


Hey, my new short block has over 8000 miles on it now. Doesn't use oil like the old one did.

My dealer told me (back in 08) if I use synthetic check the oil every time I get gas it burns synthetic and didn't recommend it didn't they also say burning up to 1 quart of oil is normal between oil changes? And someone here said his dealer won't even take a look at a car under warranty if its not burning more than 1 quart between oil changes

Here is a link to a TSB made by Amsoil. They have references to Subaru TSBs as well. The paragraph of interest is the second under the 'Technical Discussion' section.

Dealer will say 1 qt per 1000 miles is normal, same as VW.

If it still under warranty have the dealer do compression and oil consumption testing. Well take a few thousand miles, but if its still an issue and under warranty when test started, the problem would be warrantied. Mine got to the point where I needed new motor and turbo. Subaru took care of me. Hope they do to you as well.

All of the brands I have dealt with in the past say a quart in a thousand miles is within normal oil usage range. The design of this motor further compounds the issue and if you drive hard then oil usage will increase.

My 05 OBK 2.5XT uses quite a bit more than 1qt per 1000 miles but I haven't cared that much because it is not that expensive to add some here or there, especially when compared to a new bottom end. I also drive my vehicle pretty hard sometimes.

When I bought my car it had 114xxx miles (now 150xxx) worth of previous owners with probable extended/forgotton oil change intervals, low oil/no oil, or crap oil/filter combinations under its belt. The bottom line is it needs the oil and I love the car so in goes the oil. I just run an oil that suits my needs and wont break the bank.

Sorry for the long post.

This is true.

We have found if a car is burning about 1Q/1k it will eventually be found out that you have a cracked #4 piston ringland...

If it's under warranty, make sure to get it checked out with a compression and leak down test to determine the exact issue.

CAMS, great post there, welcome to the forum.

That's basically what I did, just topped it off 2/3 times a week till I saved up and did the new EJ257.

Then what do you think is normal oil consumption for these cars in a 3750 mile interval (assuming healthy engine, stock tune, and driven hard at times)?

1Q every 3500 would be "normal" in my book, unless you are tracking the car hard during every oil change, then you might say 1Q ever 2k miles.

won't an air oil separator help to an extent? because every time i take off my intercooler theres always oil there. I've been thinking about buying to see if it would help at least somewhat.

my motor with 35k miles goes through about a quart between every oil change, which is every 3k miles. (all city driving)
