Yip, our old engines must use LRP. The simple explanation is that unleaded causes more heat at the valve seats (due to the lack of any heavy metal in the fuel (lead)). this will over time cause damage, so if you filled up unleaded once by mistake, you should be fine.
To use unleaded, hardened valve seats must be fitted to the head.
