COD last week then send my proton savvy to service. LM 10w-30 i definitely better than Petronas Syntium 800. the engine runs quieter, more power as well. a bit shocked when the oil is poured because it's not clear like normal lubricant. looks very thick, and the color is black. but that's not a problem at all. hehe

will buy again for next service. will try other product too.
