Oil and Wear Analysis

Komatsu Oil & Wear Analysis (KOWA)

Analyzing engine oil and other fluids is the best way to look inside a machine’s engine and powertrain. It can help you identify trends and make informed repair and maintenance decisions.

The Komatsu Oil & Wear Analysis (KOWA) program allows you to pinpoint and solve equipment problems by providing a full range of information on both the lubricant and the machine that can support your operations and maintenance decisions.


KOWA uses highly reputable, independent laboratories across North America to ensure that you are provided with an unbiased appraisal of the condition of your equipment. KOWA’s testing facilities are ISO accredited to ensure the highest degree of accuracy and confidence. KOWA offers ‘Next-day Turnaround’ upon receipt of samples for routine analysis. Oil analysis results are compared to Komatsu guidelines to eliminate any guesswork.

KOWA is your best defense for proactively maintaining your equipment.
