Many people are running on unleaded, these are not high performance engines, the 85 280TE possibly had the same engine as yours, and that was only ever used on unleaded.

apparently even the 113 SL

had hardened valve seats, so Unleaded was fine for them as well.
You'll be ok with unleaded, but if you are worried, every fourth of fifth tankful with LRP will work, or run some Redex in your fuel as well.
