Jim Fitch:
How important is the analysis of used motor oils to monitoring and optimizing engine performance/health in motor sports? Was oil analysis a common practice during your racing days?

Mario Andretti:
The analysis of used motor oils was always very important to lubricant manufacturers throughout my career, and common practice. The technology has certainly gotten more sophisticated over time, but it remains the only way to determine if you have a breakdown of viscosity due to excessive temperatures and to measure unusual engine wear.

buster, the cost of a UOA is peanuts within the cost of racing a team.

Do you think they didn't do it, or is this another Al Unser testimonial for Prolong?

The NASCAR Cup teams I know analyze the heck out of lubricants. What they're looking for may be different than what Mario said, but they are testing every little thing possible.
