1969 Plymouth Roadrunner Convertible
Hi Scotty, I have an opportunity to buy a 69 Roadrunner. It was restored about 30 years ago but mostly sits in a garage. As you know, these cars ran on leaded fuel. Is it ok to run today's gas without additives? And what should be done before driving an old car that's been sitting for years?
Is it ok to run today's gas without additives?
Yes.
Tetraethyllead has been replaced by modern anti knock compounds, such as methylcyclopentadienyl manganese tricarbonyl (MMT) as well as oxygenates including methyl tertiary-butyl ether (MTBE), tert-amyl methyl ether (TAME), and ethyl tert-butyl ether (ETBE)
And what should be done before driving an old car that's been sitting for years?
A lot.
When is the last time it ran?
