"Shell Instant Oil Analysis, the only service of its kind in Canada, uses the On-Site Analyzer (OSA) machine to evaluate small samples of oil and reveal hidden problems in the fluids and lubricants, engines, transmissions, and power steering systems of your fleet. It only takes a few drops of oil and about ten minutes to process the sample, and you’ll receive a comprehensive, easy to read diagnosis of your vehicle."
