Operating in the UAE's extreme environment demands diesel engine oils specifically engineered for high stress and thermal extremes. For heavy-duty trucks, commercial SUVs, and fleets, the optimal choice is a premium full synthetic heavy-duty diesel oil with a high viscosity index, such as 15W-40 or 10W-40, that meets or exceeds API CK-4 and ACEA E9/E7 specifications.
