I have the same engine family 3.3L and my experience is that the engine consumes no oil. My '99 3.3L with 210K miles consumed no oil between changes, and my 2008 3.3L also consumes no oil but I've only done 20K miles total so it's barely run in. The dealer won't do anything for the relatively low level of oil consumption you have. I assume you are sure it's not a leak, which possibly can be fixed.
FYI - I use a Trasko full flow + bypass oil filter and I think that helped the '99 to stay fresh. The car went to cash-for-clunker heaven which is a shame, but the rear doors had the typical rust and the shock towers were soon to collapse due to more Chrysler rust. Even the 41TE was original and shifting like new. It had an external filter and extra large cooler. There's NO chance the 2008 41TE will last as long, it shifts way too much because Chrysler "improved" the programming
