Hi Everyone,
I have just moved to the US for work and have always loved classic mustangs. I have a 64.5 Coupe back home and today purchased my dream car - a 66 vert. My query is related to the best fuel to use for a standard 2V 289. Back home I use premium unleaded with a special lead replacement additive. Is that a requirement over here too?

Thanks in advance and Im really enjoying the boards.

You can use hi octane fuel along with a octane booster

 

If you have the unhardened valve seats a lead additive certainly won't hurt, especially in California where there are a crapload of additives in the fuel that are just that much harder on engine parts

 

just do what you have been doing. good gas and lead additive is what your car needs to stay running in good condition.

welcome to the states, and to the forums!

 

Have the heads rebuilt and install hardened valve seats so you can burn unleaded without worrying.
In the mean time 92-93 octane (Premium) should be fine.

 

And were do you find 92-93 octane fuel

 

at the gas station...

 

At virtually any gas station in Texas...

Of course I realize availability varies by state and region.

 

u can get that anywhere...87,91,93

 

No you can't.

Depends on where you live what octane fuels are available.

For the standard 289, 87 is all that should be needed.
