Used on my Satria 1.6 1995 which is eating engine oil.
Yet to go for overhauling.

Brand: Eneos
Oil Type : 20w50
Price : RM50
My Thoughts : engine smooth and oil still available even after 4K km
Rating : 4/5

Brand : Pennzoil
Oil Type : 20w50 - on the bottle said recommended for car eating oil
Price : RM45
My Thoughts : normal but almost lost all engine oil after 3K km

Brand : Petronas Mach 5
Oil Type : 20w50
Price : RM56
My Thoughts : normal

Opinion, for my car which consumed engine oil, both mach 5 and eneos is ok but eneos has been showing better fuel consumption compared to mach 5
