Using Castrol Magnatec 5W30 Semi Synthetic meant for Petrol & Diesel Engines. It has these numbers mentioned on the 4L Pack "470492".
Checked MSDS of this product number and it confirms product is for Petrol and Diesel Engines. I intend to continue using it. Btw in revamped 1GDFTV of Fortuner with 500NM torque from 2021 onwards, the owners manual advises to use 5W30 or 10W30 engine Oils which meets API CF, CF-4, or ACEA B3, B4, B5 or JASO DL-0 Specs.
