The engine is listed in my signature. Its a 1KD-FTV which are known to clog the intake valves due to the EGR. I've considered installing a catch can but i would need to order it from overseas and its a PITA.
All of the oils i listed are the US formulations, most distributors here import them from the USA.
Most oils here come from the USA anyways, the only ones i know that have a different formula and name are the Shell HX line of oils. All the Chevron, Valvoline, Mobil and Amsoil oils are imported. Theres also some Shell oils that are sold here but not in the US such as the Helix Ultra line.
