I would recommend 5w30 and use fully synthetic so it will improve your vehicles life time but remember if you switch to synthetic you cant go back to regular oil it will cause problems but that's the best you can do for your mustang.

They had the 2.3 inline 4 cyl, the 2.8 V6 which was the biggest engine available for the 1974 Mustang Mach1 fastback, and the 5.0 V8 which was in the Mach1 fastback for 1975-78 and an option for the notchbacks and Cobra ll. It was a standard engine in the King Cobra fastback in 1978
Under the car. Behind the engine. Bolted to the frame. If you have bucket seats, it is down between the seats under the car.
No such thing as a 76 Mustang. The Mustang didn't exist between 1974-1978.
