Which Oil/Filter Combo and Duration? - Toyota Yaris Forums

I didn't realize the OEM interval was being pushed to 10k. Is that with the 1NZ?

I wonder if there's a certain kind of oil that has to be used to get that. I sure wouldn't trust just any ol' oil to go that long.

When I was on AMSOIL Signature Series 5W-30, I wasn't losing a drop. All the way up to 14,000 miles, our dipstick never showed less than absolutely tip-top.

Back when I was using Mobil1 5W-30 (first 70,000 miles), I changed every 5k and by the time 5k rolled around, I had lost some oil (may .3~.5 of a quart). I never did analysis on the M1 in the Yaris but I'm going longer and getting better fuel efficiency with the AMSOIL.
