Motor Oil

Motor oil is one of those things you don’t want to guess on — using the wrong viscosity or skipping a change can lead to real engine wear over time. Nixa Hardware & Seed Co stocks motor oil from trusted names like Castrol, Pennzoil, Shell Rotella, and Motorcraft, covering conventional, synthetic blend, and heavy-duty diesel options. Your owner’s manual will tell you the right viscosity grade — like 5W-30 for most modern gas engines or 15W-40 for diesel work trucks — and that’s always the best place to start.
