Most 1986 Chevrolet Sportvan owners follow a 5,000–7,500 mile interval with conventional oil, or up to 10,000 miles with full synthetic. Always check the oil life monitor if equipped, and consult your owner's manual — Chevrolet recommends intervals based on driving conditions, not just mileage.

Yes. 5W-30 is widely available as a full synthetic, and synthetic is safe (often recommended) for the 1986 Chevrolet Sportvan. What matters most is matching the factory viscosity and specification, then changing the oil and filter on schedule.
