Just hit 200K on our 2004 Lexus RX330; purchased new in November 2003.
Used a mix of 4 quarts Pennzoil conventional (switched to high mileage around 90K) and 1 quart of Pennzoil synthetic with a change interval of every 5,000 miles. Despite additives not being very popular, have used 4 ounces of Tufoil (periodically). Initially used Toyota filters and switched to Fram Ultra a few years ago; change every other oil change. Gas at SAM's club with 85 octane (live in Colorado). Solid/very reliable SUV.
