The main difference between 10W-40 oil and 15W-40 oil is that 15W-40 oil has a higher viscosity than 10W-40 oil. 10W-40 oil allows the engine to run freely.
The W stands for Winter. The 5w30 flows easier at lower temperatures. It is a 5 weight oil at low temperatures where the 10w40 is a 10 weight at low temperatures.
Viscosity. 5W-30 is a "thinner" oil than 10W-40 is.
The 10W 40 oil is thicker and is thought by many to be more efficient.
Neither one of these. Your car requires SAE 5w30 weight oil.
Either 10w30 or 5w30 are fine.
10w-30 is the recommended oil for a 2004 Chrysler Pacifica3.5L 10w303.8L 5w30
5w30. it should say that on the oil cap. it takes 6.5 quarts with a filter.
SAE 5w30 oil is an oil designed for cold and warm temperatures. It is basically a 5 weight oil when it is cold and becomes a 30 weight oil when it reaches full operating temperatures.
The weight of the oil when it is cold. The 15w is a thicker oil than the 10w when it is cold.
5w-30 is best to use but yes you can use 10w -30. Any w30 oil will work but 5w30 is recommended
if you live in a very cold region, otherwise 10w 30 is better
