does the oil type matter on how it will start up? i went to autozone and they told me to use the 5w-30 kuz it starts up the car faster. is that true? somtimes they are wrong. and should i get valvoline or something else? i need something that will start the car right up since its winter here and my car hasnt been starting right up lately, so im going to do an oil change to see if there is any difference in my car. thank you for your helps.
