Synthetic lubricant manufacturer Royal Purple introduced its new commercial lubricant product line, Duralec. The new line of high performance lubricants has been developed for the over-the-road trucking, construction, mining, agriculture and heavy-duty fleet markets to optimize equipment performance.

Duralec commercial products include heavy-duty motor oils, transmission fluids, gear oil, multi-purpose grease, coolant additive, tractor fluids, hydraulic fluids and diesel additives. Each product is formulated with Duralec’s premium additive packages to deliver protection and peak performance in today’s high-tech engines regardless of driving and operating conditions, according to the company.

Some of the new products include:

Duralec Super

Royal Purple’s Duralec Super motor oils are high performance synthetic engine oils. They are made for EPA 2007 and 2010 emissions equipped diesel engines requiring the use of emissions compliant oil. Duralec Super is formulated to maximize component life, extend drain intervals and improve fuel performance. Its synthetic formulation has high temperature break down resistance and low temperature pumpability to minimize cold induced startup wear.

Duralec Ultra

Fortified with a high level of zinc/phosphorus anti-wear additive and Royal Purple’s proprietary additive technology Synerlec. Duralec Ultra is formulated to maximize performance and meet the demands of today’s heavy-duty engines. It is recommended for use in both two-cycle and four-cycle diesel applications including automotive, commercial fleet and stationary industrial diesel engines. It provides a lower coefficient of friction to save fuel and its synthetic solvency keeps internal engine parts cleaner than detergents alone, according to the company. Duralec Ultra also provides oxidation stability that extends drain intervals and minimizes harmful oil degradation.

Duralec ATF

Royal Purple’s Duralec ATF is a synthetic high-performance automatic transmission fluid formulated for demanding operating conditions. The low co-efficient of friction and high film strength of Duralec ATF helps to reduce heat and wear, and is more oxidation-stable than other transmission fluids for longer fluid life, according to the compamy. Duralec ATF is fully compatible with most other automatic transmission fluids and can be mixed with these other automatic transmission fluids. 

Duralec MTF

Duralec Manual Transmission Fluid is a blend of premium mineral and synthetic lubricants. It provides friction performance with both the metallic and nonmetallic friction materials found in today’s hi-tech powershift transmissions. The company says MTF promotes greater oil life, smoother brake operation, reduced gear wear, controlled powershift transmission friction and more reliable equipment. It also meets the requirements of Caterpillar TO-4, Allison C-4, API CF and CF-2, Eaton and Dana manual transmissions.

Duralec Gear Oil HD

Heavily loaded gears can gain maximum protection while maximizing power throughout the drive train by using the Duralec Gear Oil HD. Royal Purple’s ultra-tough, high performance commercial automotive gear oil is recommended for use in truck and automotive front or rear differentials, manual transmissions and lower gear units of marine engines that specify use of an API GL-5 or GL-4 fluid, it makes gears run smoother, quieter, cooler and longer without overhauls, according to the company.
