The recommended oil grade for a 1996 Dodge V6 truck depends on the climate where you live and the specific engine. Your owner's manual is the best source for this information. It will specify the recommended viscosity (like 5W-30, 10W-30, etc.) and the oil type (conventional, synthetic blend, or full synthetic).
Generally, for a 1996 truck, a 10W-30 or 5W-30 would be common recommendations, but again, check your owner's manual. Using the wrong viscosity can damage your engine.
