tis time i went to my 1st SC, they quote me 5W40 petronas apa 3000, RM219.
So expensive but quality not bad.. n with the free beg, 

Lastime the other SC only got 15W50 or 5W50, forget d... price RM198. 

Heavy... But still i can naik genting with ease... haha..

BTW, guys.. i checked proton website for the recommended service manual, 20k mileage actually juz need to change eo, oil filter and gasket only.. those apa radiator coolen boleh tahan sampai 40k, spark plug n air filter 30k.

I change plug n air filter outside d n for this 20k service(atually i service at 22k, coz busy no time drop my car), labour baru Rm45. total damage for my 4th service baru RM290.

So bear in mind, dont kena chop 

RM 45 is for authorized SC and not Proton Edar or EON, IINM and that one still not the cheapest rate.
10% discount is for what? All? Parts? Labour? What is the breakdown?
If actually they mark up before give discount also there is nothing to shout about.
