Thanks Astroboy, got it.. so the advert is consistent then. If you want a longer engine life, use 0-40W and which is slightly thicker.
These are premium lubr. The most expensive in Kedai Mesra at rm223 for 4 liters. I would not think 0-30W will shorten your engine life if you change it every 10k. Even if you use the thickest lubr but change it every 25k, don't think it will prolong your engine life. Furthermore, the ads says it suposed provide exceptional engine cleanliness. Thus, protection is there but then it should has its limits.
