Okay so my Passo has run 68k. Recommended engine oil according to my Japanese owner manual says 0W-20 or 5W-30. Which one would you recommend for the best fuel efficiency (manual says 0W-20, but also says that’s for when the car is new)? Temperature rarely falls to 0°C here.
Any of the “name” brands should work. If you’re skeptical you can always just get the official Toyota oil from a dealer (comes in quart bottles).
