Does a 1974 amc jeep cj5 take unleaded gas?
No, a 1974 AMC Jeep CJ-5 originally was designed for leaded gasoline. While some may run on unleaded, it's not recommended. Using unleaded fuel in an engine designed for leaded fuel can lead to valve seat recession and damage to the engine over time. It's best to use leaded fuel or a fuel additive designed to protect against this issue if leaded isn't available.
