...leaded gas are they right? it is a 1966 dodge dart 270 model with a 225 charger slant six it has an automatic transmission (like that makes any difference) and hasn't bean run in 10 years and i recently took it out of the barn and got it to fire up and someone warned me that it would eat up the lubrication in the cylinders if i kept running it with unleaded and so i have parked it for now, ALSO if you have any idea where i can get ahold of some leaded gas if this is the case please let me know
 
You can't buy leaded gas, so you don't have a decision to make.

You should just run the unleaded gas. If at some point the car needs a valve job, then just do the valve job then. Today, the strategy is to ignore the problem. 99% of the time, ignoring it works forever.
 
you can run unleaded in it and it wont hurt a thing on it,all unleaded does is not create the build up on the valves like the older engines would get,you can add a fuel additive to it to boost the octane rating if you want to and that wont hurt it either ,but it really isn't necessary,run unleaded in it,it wont hurt it,good luck.
 
There is a lead additive available at auto parts stores. Lead provides a critical wear reducing function by depositing a thin, protective layer of lead oxides on valves and valve seat surfaces reducing the risk of Valve Seat Recession. Without a Lead Replacement Additive, the valves will burn out at a rapid rate, leading to costly cylinder head repairs and possible major engine damage. The lack of valve lubrication often results in premature failure of exhaust valves due to a phenomenon known as Valve Seat Recession.
 
1. You were steered wrong.
2. You cannot buy leaded gas in the US anymore, and
3. It's perfectly OK to drive.

Use a lead substitute (available at any parts store) if you feel more comfortable, or you can have the valve seats replaced if you are planning on having any machinework done.
 
Nah, It'll be fine. At one time, when they first banned leaded gas, folks were afraid the lack of lead would ruin the valves, but time has proved that the valves are hard enough to take it. You may find she runs better on premium, but that's an octane thing. The slant six is an excellent motor. Practically indestructible. They used to have a product "lead substitute" available at auto parts stores and such, but i think its a waste of money.
