All engines, transmissions, and final drives are original and un-rebuilt. The Camry and Dakota both burn some oil between 5K changes (Camry = 1qt./1K miles; Dakota uses less, but the use varies depending on what load/speeds it sees); the Highlander uses about 1qt/5K miles. The Sonata doesn't yet consume oil between 5K changes. Oils (always synthetic) and filters (always reputable brand or OEM) vary, depending on what's the best sale price/rebate.
