Hello, I have an original condition 1988 Z24 (2.8 Multi-Port Fuel Injection) that has approx 250,000KM (155,000Miles) on it. I have always used conventional 5W-30 (OEM recommended) oil for oil changes. Should I stay with conventional oil or move to a synthetic product? Thanks

It's your choice. Synthetic oil is more expensive but has better lubrication properties and lasts longer. (I use synthetic oil in my nearly 60-year-old Rebel convertible and my other older vehicles.)
