Evening all, I'm looking at buying a 1979 280ce. I did'nt ask the bloke who owns it whether he puts un-leaded in it or not, or if he does, should he be doing so ?? Do they run on un-leaded ok, or do they need converting with hardened valve seats or the like ??? Or would it be cheaper to just...

has anyone had this done to there's or know what's involved? Would valve seats have to be done or would it just require a simple timing adjustment?

I got in touch with the local mers dealer today to ask what i have to do to change my 1984-5 w123 230e from leaded fuel to unleaded fuel and they said that i can just change over no problem then the man on the phone said that he personally would put some leaded fuel in every 3-4 tank fulls if...

I can't believe what I did yesterday, my last cars were a 320d touring, audi a4 tdi avant, audi a4 tdi saloon and now I have an ML270cdi. And yesterday I put BP's ultimate unleaded in my car! Like an idiot I didn't even read the pump properly, I had filled up with ultimate diesel a couple of...
