Fuel Question
I am a proud owner of a 1973 Mercedes 230 V6. This car is a direct import from Germany, it never has been modified for the US market. This car runs on LEADED Fuel, which is no longer available, I am aware that there is an additive available, I have used it, but I am having trouble getting the mixture right, can I use regular UNLEADED gas, without causing any damage to the engine? This car has 112000 original kilometers on it, it’s barely broken in. Any suggestions are greatly appreciated.

RE: Fuel Question
I use premium unleaded with no additives in my '70 Chevelle. There are a lot of old cars from the leaded gas days still on the road. The people I know with them use premium unleaded. Regular unleaded octane is too low and causes problems with pinging.
I doubt your car has very high compression, but you might need to retard the timing just a bit.
The valves may not last as long as they normally would. The lead acted as a lubricant. The engine won't melt down or anything. It may run a little noisier.
