Heavy Duty Fluids

Ultra1Plus heavy-duty fluids are engineered for the hardest-working diesel engines and equipment, on-highway and off-highway. The range includes conventional, synthetic blend, and full synthetic heavy-duty motor oils, plus the off-highway hydraulic, transmission, tractor, and agricultural and industrial lubricants that keep fleets and machinery productive.

Built for soot handling, thermal stability, and long drain performance under load, these products support the API service categories and OEM requirements common to commercial trucking, construction, and agriculture. Confirm the exact specification on each product page, and contact us for truckload, pallet, and distributor pricing.
