Catch the Wolf Pack on the Road.
From farm shows to fairs, see our products in action, and learn how we keep Wisconsin moving.
Wisconsin cold doesn’t wait. Neither should you.
Don’t let freezing temps slow you down. Call the Wolf Pack to winterize your fleet and make sure your lubricants, fuel systems, and DEF are ready for the cold.
You rely on us to deliver. Our promise is to go the extra mile.
We offer comprehensive solutions tailored to your needs—because your business isn’t the same as the one down the road.
Our world relies on your fleet.
How you protect your equipment makes all the difference. You need to keep it ready and moving, which makes the oil you choose to protect it more important than ever.
Push boundaries with lubricants that outperform current standards.
We work with you to ensure your lubrication solutions minimize downtime, reduce maintenance costs, and extend equipment life.
