After 550,000 miles on Delo, Hoge Motor’s Mack MP 8 engine looks excellent

Tommy Hoge and his wife, Crystalee, represent the second generation of family ownership of Hoge Motor Company, founded by Tommy’s father Lawrence in 1963. Chevron recently conducted a teardown of Delo heavy duty diesel engine oils and coolants.


Based north of Nashville in Springfield, Tennessee, the company owns and operates 40 cabs and hauls flat-bed freight, primarily aluminum and steel for manufacturing customers.


On-time dependability is critical to Hoge’s business. A delayed delivery can mean a customer’s plant having to shut down to wait for the product. Hauling heavy loads in very high temperatures, Hoge Motor needs lubricants they can rely on to maximize uptime. Tommy has the utmost confidence and satisfaction with Delo products.


Hoge started using Delo heavy duty diesel engine oils and coolants in 2013. Earlier this year, we tore down one of Hoge’s Mack MP 8 engines that had travelled 550,000 miles using the new API CK-4 Delo® 400 XLE 10W-30 with ISOSYN® Advanced Technology, as well as Delo® ELC extended life coolant. The condition of the engine and cooling system components provide a vivid demonstration of Delo’s piston deposit control, oxidation stability and anti-wear protection properties.
