20W50 is the " thicker " oil
10w30 is thicker than 5w20
More than likely 10w30. Check your owners manual or call a Chevy dealer to be sure. Sometimes it is written on the oil cap. The factory specifies 5w30..in cold climates it helps the oil to flow better. In warm or hot weather 10w30 is acceptable..but under NO conditions should the 2.4 engine use any thicker oil..thicker would be 10w40.. 20w50 etc.
You can use 10W30 or 20w50.
15W40
10W30 in winter. 20W50 in the hot months.
10w30 or 20w50 is great
10w30 in the winter time---- 20w50 in the summer time.
Use 10w30 in the Winter and 20w50 in the Summer.
10w40 is thicker (but only when hot, they are the same thickness cold.)
