Schaeffer's 9000 SynShield® OTR Plus 5W-40 Full Synthetic Engine Oil - 6 Gallon Case

Keep your engine running clean and protected with Schaeffer's 9000 SynShield® OTR Plus engine oil.

This is the real deal—a full synthetic 5W-40 oil, designed for heavy-duty applications, especially over-the-road (OTR) trucks and equipment.

You're getting a full case of 6 one-gallon jugs, so you'll have plenty on hand for oil changes and top-ups.

This oil is formulated to handle the extreme conditions of long-haul trucking, providing excellent wear protection, deposit control, and all-around engine cleanliness.

It's made in the USA by Schaeffer's Oil, a brand known for high-quality lubricants.

Just a heads-up, there's no warranty on this, and it may have a California Prop 65 warning.

But if you're running a rig that demands a top-tier synthetic, this 5W-40 is a solid choice to keep everything moving smoothly.
