This is my 6th UOA from 0 to 59600 km in Toyota Highlander. You can see all results of different lubricants in one table. First OCI's shows big number of wear metalls and Si, but it is usual situation for new Toyota engine 2GR-FE. The lowest wear was with TGMO 0W-20 (lowest viscosity among oil oils) in summer period))). VOA of Castrol is here http://www.bobistheoilguy.com/forums/ubb...al_#Post3253660

I agree. Now I am om 5W-30 ACEA A5/B5 full SAPS oil but next OCI will be on 0W-20. I will try another 0W-20 from the market, may be Mobil or Idemitsu.

all numbers were tested, (1) - FF oil - sample from the engine after 200 km 2GR-FE is a good engine. It does not kill oil)))
