1969 Coronet R/T gas tank size

[Sequoit]

Hi. What is the gas tank capacity of a 1969 Dodge Coronet R/T 440, 3- speed automatic?
Also, is it safe to burn 93 octane or should we burn only 91 without ethanol?
Thanks in advance.

Fuel tank holds 19 gallons.

91 or 93 octane depends on what cam you have, and what your timing and compression is. Too many variables to give an accurate answer.....

I'd run whatever your engine likes the most.....

The octane level will depend on what your car likes.

As for ethanol free... I highly recommend it if you can get it and afford it.

The Maverick gas stations near me carry it and the price is not significantly higher.

There are some stations that have higher octane
