When it was new, it would probably have liked Premium, the good stuff.
Who knows what has happened to it since new, so try what you like. If it knocks using a lower, cheaper octane, then try a higher grade.
Good luck at the shows!

Hi I need some "guy" help. My boyfriend used to help me with all this and unfortunately he passed away. I need to get my car back to the car shows as we won best in show every weekend! Have all the trophies to prove it too. Anyway, please help??? What kind of gas do I put in this thing? No I am not blonde, but am at a loss because he took care of everything! Thanks anyone.......

You have a Buick 430. No more than you drive it I would not worry about lead additives. Just use pump gas premium and go. I would avoid gad with ethanol added if I could.

As stated the 430 runs best on premium fuel, the higher the octane rating the better ! Additional lead additives are not needed.

I would avoid gad with ethanol added if I could.
i thought pretty much every state in the country was requiring 10% ethanol now?
regardless, if you can find a gas station that sells race fuel ( normally a Sunoco somewhere near a circle track ) or AvGas ( there are many automotive gas stations out near the swamps that sell Aviation Gas to the airboaters ), you won't have any issue with ethanol.
if you have knock problems you could mix AvGas / Race gas half and half with premium and that should take care of any problem.
