I switched over to Valvoline Maxlife which is a synthetic blend. No problems so far, it was recommended by one of my mechanics.

In fact i just drove in there yesterday to get topped off to prep for some highway miles (they top off all my cars for free) because I thought for sure with less than 1000 miles till my next oil change that I'd be low. Only took 1/2 qt and they gave me the rest of the qt "to go". So far I wouldn't categorize my engine as one of those problematic oil eaters at all. Knock on wood.
