Valvoline offers two types of Total Driveline Lubricants :

Heavy Duty TDL PRO  GL-4/5 is officially OEM approved and designed for use by true professionals to ensure high performance and protection in modern, in-warranty, trucks and buses. Through an advanced additive technology, it guarantee superior protection against wear and corrosion, outstanding thermal stability over a wide temperature range and provides easier shifting at low temperatures.

The conventional Heavy Duty TDL  is best recommended for use in multi-vehicle/multi-brand operations when trucks or buses have run out of warranty and no longer require an officially approved (and more expensive) TDL oil. *
