Just a quick follow-up on this topic in case anyone ever has the same question I did.
Did my compression test. According to Helms shop manual, normal compression should be around 163 psi, minimum compression around 138 psi, and all four cylinders within 14 psi (if I remember those numbers correctly). My compression is good, even high: 175, 190, 185, 185. So I know oil consumption can be the result of many things, but I guess I can rule out poorly sealed cylinders. Of course there are a thousand places where oil could be leaking/getting into the combustion chambers and of course I haven't checked them all. But since it's a fairly new engine I wouldn't really know any good places to start looking or anywhere that would be worn out. I tried doing some looking around as to what was considered "high" oil consumption. A number I came upon fairly often was 1 quart every 1000 miles. --> http://www.practicingoilanalysis.com/article_detail.asp?articleid=541&relatedbookgroup=OilAnalysis
Seems like a couple others have had similar oil consumption as me as well. And I do a lot of heel-toe downshifting so the engine is running in high vacuum somewhat often. So I dunno, I wanna say what I'm seeing in my car isn't too abnormal or any cause for concern. I'll keep an eye on it. If anyone has any other input on what sorts of oil consumption rates they have seen in their evos (or any other input), please post.
