About Us

SPEEDiagnostix evolved from…

One family’s experience in the racing industry. Recognizing the need for fast turnaround used oil analysis, the Speed family founded SPEEDiagnostix to provide expedited, expert used oil analysis services. Tailored to meet the unique needs of racers, enthusiasts, engine builders, performance parts manufacturers and classic car owners, SPEEDiagnostix provides data and analysis that draws from decades of racing, engine building, oil blending and used oil analysis experience.

The day-to-day operations of SPEEDiagnostix are handled by Caroline Speed - the grand daughter of former NASCAR driver and World Karting Champion, Lake Speed, and daughter of Certified Lubrication Specialist, Lake Speed, Jr. SPEEDiagnostix combines the passion and experience of the Speed family into a service focused on quickly delivering to our customers valuable information about the health of the oil and equipment being sampled.
