Hi,

I own a 1978 280 SEL (W116), and live in the UK. Next year, leaded fuel will be withdrawn from sale, leaving me in the lurch ! Can anyone give me advice on whether my car (done > 100,000 miles) can run using unleaded ? Does any work (timing, valve seats etc.) need to be done ? Thanks in advance.

PS The engine no. is: 11098412038453
