Thanks guys...looks like his best bet is to drive far enough away from MKE to get NOT reformulated gas and use 93 octane. If he is uncomfortable with the valve seat wear potential then a bottle of lead additive might be in order.

I found this from Chevron...which pretty much says no lead gas is fine with old cars cause they aren't driven much or very hard. Makes sense, but I'm always cynical of anything a gasoline company says .

Question: will a mix of xylene or toluene be OK?? Any lead in either of them?? Downsides to using them in old engines??

Thanks guys...Bob
