an expert will probably tell me differently, but suzuki's didnt make there head out of cheese parts, and i have been running unleaded since forever. seems to be ok.

thanks mate I will give it a go and see how she performs. I just didnt want to damage a good motor. The guy I got it from says he has been using an additive forever so hopefully I wont wreck it.

It's usually the valves that are the worry in using unleaded in a leaded car.Spike_Sierra wrote:an expert will probably tell me differently, but suzuki's didnt make there head out of cheese parts, and i have been running unleaded since forever. seems to be ok.

Running unleaded in engines made for leaded fuel damages the valve seats by hammering them up into the head.
The term is 'valve seat recession'.
Suzuki's all (4 strokes)have alloy heads and therefore already have hardened valve seats (Stellite) so unleaded is fine with or without additives.
