anyone had there car burn 2 quarts of oil in 5000 miles with no apparent leaks?
or can guess why one would do that?

 

Have you been running it hard? That is a lot of oil, but it's not unheard of to burn a couple of quarts on a single hard track day. Have a compression test done. If you're burning it you should be able to smell it. Does it smoke when you start it up/ come to a stop/ let off the throttle and step on it again?

 

well i have neglected to check it for about a month, and have been to the track once in that amount of time, made me sick to my stomach when i pulled the stick, but no smoke.

 

You burned it on the track. Ii don't know how long you have had your subie for, but my advice first and foremost; Top you oil off before running your car hard. On a track day go to full and throw in andother half of a qt. Check it between sessions. The wet sump design allows the boxer to suck up oil like no other. Starve that motor of oil and a gaurantee you'll be replacing it due to rod bearing failure, probably #4.

Side note:
Run a 10/30 all the time and on track days don't be affraid to run a 10/40 or even 0/40

 

actually i try to run 20/50, texas heat
