I brought in my old proton saga to the shop and they sold recommended me a Nasa 20W-50. Since im noob in this department, i took it. Service costed about RM95.

Now that i read up, i feel i got ripped off a bit. but oh well.
20w-50 should be a high viscous oil right? meaning high temp and high Fuel consumption.
