    Not many surprises considering it's basically the Tundra powertrain. A few interesting items:
    • Minimum 91 octane fuel required, lower octane prohibited, at least on paper.
    • 21 gal fuel tank down from 23 gal in previous gen.
    • 0W20 or 5W20 engine oil, close to 8 qt!
    • Engine coolant capacity varies depending if the vehicle is optioned with rear A/C.
    • Rear diff oil capacity is 7 qt! 13 lb unsprung weight just in the oil! :laugh:
    • Front driveshaft has a zerk for the slip yoke, but rear driveshaft apparently doesn't.
