Glendive, Montana
Fluids & Lubricants
The right fluid is the one that meets the manufacturer's specification — viscosity alone doesn't tell you that. Modern diesel engines, aftertreatment systems, hydraulic systems and transmissions each call for specific fluid specs, and the wrong one can void coverage or cause real damage. Mondak supplies engine oil, hydraulic oil, coolant, transmission fluid and grease for trucks and equipment where stocked, and helps match the fluid to the application. Inventory varies, so call ahead to confirm what's on the shelf.

THE MONDAK APPROACH
Diagnose first. Repair with purpose.
We match fluids to the manufacturer's specification, not to whatever is on sale. Bring the engine or machine information — or the product you've been using — and we'll confirm what the application actually calls for.
Fluids can be picked up at the Glendive counter or supplied as part of a lube and PM service.
