After going through the Mb 229.3 and Mb 229.5 list, I found out the cheapest oils which meet these requirements which can easily be found in Malaysia.

For MB 229.3, it would be the Caltex Havoline Formula, Caltex Havoline Synthetic Blend (RM 95-110), and Shell Helix HX7(RM 101-135).

Interestingly, Caltex Havoline Formula is non-synthetic dino oil. However, there have been some not so positive reviews regarding the Havoline engine oils. Do your due diligence first.

For MB 229.5, it really depends on what’s on sale. Currently, Castrol Stop Start Fully Syn 5w30 is going for RM 150 on gemfive.com. (Do note that in Germany where labelling laws are tighter, this Magnatec is not labelled as a full synthetic, but rather as a hydrocracked synthetic)

I was mainly looking through the major brands in those MB specs sheets. Please do let me know if I have missed any.
