Fuel and Lubrication Testing

Expert Testing for Diesel, Lubricants, and Alternative Fuels

Clark Testing’s Fuel and Lubrication Testing Laboratory offers comprehensive testing services for fuels, oils, and lubricants to ensure quality, performance, and regulatory compliance. With over 20 years of experience and a stringent quality assurance program, our laboratory is trusted by clients in the automotive, industrial, energy, and aviation sectors for accurate, on-time results.

Our facility is equipped to perform advanced wear testing using standardized test rigs. This includes Four-Ball Wear testing (ASTM D4172, D2266), Hydraulic Pump Wear testing (ASTM D7043), and FZG Gear Wear evaluations (ASTM D4998, D5182, DIN 51354, and ISO 14635). These tests help determine how lubricants perform under stress, supporting product development, quality control, and formulation validation.

In addition to wear testing, Clark Testing provides full analysis of physical and chemical properties for a wide range of fluid types. We test conventional diesel fuels, alternative fuels such as biodiesel and ethanol, aviation turbine fuels, fuel oils, motor oils, greases, hydraulic fluids, and crude distillates. Each analysis is performed in accordance with applicable ASTM specifications to meet industry and regulatory standards.

Our specialty services are tailored to support everything from product certification and compliance to formulation compatibility studies and performance benchmarking. We regularly assist clients with quality assurance programs, product comparison testing for procurement, and evaluation of new fuel or lubricant formulations before market release.

Beyond laboratory testing, we offer expert technical consulting to help clients interpret test data, solve performance issues, or meet specific application demands. Our team works collaboratively with manufacturers, refiners, and equipment operators to ensure their products meet performance expectations and regulatory thresholds.

Clark Testing’s fuel and lubrication lab is ISO 17025-accredited and supported by a team of experienced chemists and engineers. We pride ourselves on delivering detailed analysis, actionable data, and responsive service that helps our clients maintain product reliability and competitive advantage.
