hmm, 0w20, not really suit ur car in our hot weather nation

the 20 at the end is means the viscosity of the oil when the engine reach its optimal operating temperature, so, the higher the number, the better the oil to stay in its oil form to lubricate the engine, but depends on ur engine, the higher the number, oso means thicker oil, engine will makan tenaga to crank, hence makan minyak sikit

get 0w30 for normal driving
