Misc. What type of gas is best for an old engine?

[BMK84CJ572]

What is the best fuel to run in my '72 CJ with the AMC 258 i6 / 4.2l ? I assume ethanol free, but should I use a lead replacement additive or anything else?

This may have been posted previously, but I'll post again just in case... Here's a good link ethanol free gas stations if you are looking for ethanol free gas in the US or Canada.

Just regular gas from any old pump. Good luck finding ethanol free

Your CJ has hardened valve seats. No reason for lead additive. It was made for unleaded.
Ethanol will not hurt the engine. Just hard on the rubber lines if it sits.

Gas is the cheapest thing you'll ever put in your Jeep.
I run premium no Ethanol.
