Gas! Ignorant, but enthusiatic
I just bought a 64.5 hardtop, 54K miles, straight 6, 170ci, 3 speed. Any thoughts on best fuel. ?regular or middle or high test? Any reason for a lead additive?

Welcome to the forums !! Wow, you can read yourself silly about what to do when running leaded fuel engines on todays unleaded.
My advice, and I did this on my last 69 440 engine, for a Plymouth I owned, have a competent auto machine shop do a valve job, and install the unleaded exhaust seats in the head. Sure it will cost a little extra now, but you can drive in peace. You won't risk damage to an engine that is original to your car, and no doubt Very hard to find one like it today.
Cheap insurance in the long run.
Just my 2 cents.
Good luck with your project

That is a really nice Mustang. Looks very good. The 170 ci straight six was designed to run regular 87 octane leaded gas. In regards to the fact that the engine was designed for leaded fuel...
A friend of mine used to work in development for Shell. Almost all modern gas contains aditives that take the place of lead for lubricating the valves. I have run many vehicles from that era on today's gas for many years and I have never had a problem.
If your Mustang had a high performance engine you would have a problem with today's gas not having sufficient octane as many of the high perf engines of the day required 102+ octane however the 170 ci inline six will run perfectly ok on regular.
So as long as you are using gas from one of the major companies like Shell, Sunoco, Chevron, ect. you will have no problems.
Enjoy your Stang!

I was wondering what is a 64.5 Stang. I know that the original Stang was born in 1964, does that mean that the 64.5 were manufactured in the middle of the year. Well I like your car, and I think that you have a treasure there. Welcome to the forums.
