Appreciate the replies regarding different oil providers and their Specs.
I would like to go back to my original problem with Mazda Engine oil recommendation for my e-SkyActive X Mazda 3 for which Mazda recommend only 0-20W oil or alternatively API SN (or higher) 0-20W oil.
I contacted Mazda Customer Services and they referred to their technical department who advised that Mazda Original Supra 0-20W is different from Mazda Original Supra X 0-20W, since Supra 0-20W is for SkyActiveG Engines whereas Supra X is for SkyActiveX Engines.
Referring to Owner manuals for my past 2017 Mazda 3 SkyActiveG and current 2022 Mazda 3 SkyActive X, the Engine oil viscosity and temperature specs for Supra and Supra X show no difference whatsoever between the two. Must be other special ingredients?
Very confusing
