I plan to use Pennzoil Ultra Platinum oil at 275, 500, 1,000, 2,000, 4,000 miles & at 4,000-5,000 mile intervals. New Premium Guard Extended or CarQuest Premium filter at every change interval.
Toyota parts.com through my local dealer run discounts every holiday. A six quart box of oil comes to $26 and the filter is like $4-5. So for $30 one gets OEM oil change, and I personally like to do it every 3k miles.
