Caltex lubricants stand for one thing above all else: reliability. properly lubricating the inside of a heavy-duty diesel engine requires more than just creating a protective film. Caltex’s new advanced formula Delo® 400 MGX SAE 15W-40 provides excellent soot dispersancy, wear protection and sludge control to guard against loss of engine life and help reduce fuel and oil consumption.

The family of Delo® Extended Life Coolant products helps, reduce the number of coolants required to protect diesel engines, eliminate the need for supplemental coolant additives (SCAs) and repetitive inhibitor testing, minimize operating costs by eliminating costly coolant maintenance, and extend diesel engine life and coolant system performance.
