A1. All samples should be taken at operating temperature (hot) and the oil should be well mixed.

A2. The laboratory will keep the oil sample for six weeks.

A3. No. New or used lubricating oils are not hazardous, flammable or toxic according to the Regulation for Hazardous Material (DMM 601.10.6) which indicates that liquids with a flash point above 200 degrees F are free of restrictions when shipped by air or surface transportation.

The average flashpoint of used engine oil is 380 degrees F and the average flash point of used transmission or hydraulic fluids is 340 degrees F. If the minimum flash point of 200 degrees F is met, the collection and shipping containment provided in OAI test kits is sufficient for shipment by air or ground transportation.

Postal Regulations require that the sample collection containment have a lined, screw-on lid to prevent leakage. OAI's oil analysis test kits provide a plastic sample collection jar, a lid with a liner and a plastic return mailer for secondary containment.

A4. In the area of technology, engine lubricants must consistently evolve toward higher performance levels, linked to engine advances, use, manufacturer requirements and requirements of users and law-makers.

A5. Oil analysis is a diagnostic preventive maintenance tool for monitoring and evaluating lubricant and equipment conditions. It allows you to maximise asset performance and reliability by identifying minor problems before they become major failures. It can safely extend oil drain intervals and ultimately the life of your equipment – saving you time and money.
