[SIZE=4]Hello Tsikoteers ![/SIZE]

I'm currently driving a corolla xl year 2000 model. Odo is around 80t kms or so. Recently had an oil change and the oil used was valvoline 20w-50 mineral oil.

Question is ... is this the correct grade / viscosity for my car ? I'm currently experiencing difficult cold starts. Car idle is ok during startup (while cold) but vibrates more upon reaching normal temp.


Should I be using synthetic ?? How about the grade ? 10w-40 ? 10w-30 ? Any experiences / suggestions ?

Thanks in advance ! [SIZE=4]Happy new year to all ![/SIZE]
