Depending on their composition, the performance properties and stability of liquid lubricants (oils) will remain intact for a number of years provided they are in their unopened, original sealed containers and have been in protected storage* that prevents exposure to UV light or severe high/low temperature cycles.

Industry performance standards and lubrication formulations can change. A lubricant which is near its expiry date may still perform to its original design, but it may not meet the latest requirements and specifications of newer equipment. It is always advised to consult the OEM manual.

The shelf life of Petro-Canada Lubricants lubricating oils is as follows:

Indefinite Storage Life – Base Oils and Process Oils

These may be stored indefinitely under protected conditions without any significant deterioration in performance. Slight changes in appearance / color may occur. If they are used as part of a manufacturing process or application, the product properties should be reconfirmed if over 5 years old. The only exceptions are the PARAFLEX™ HT 3 and PARAFLEX™ HT 5 process oils which should be reconfirmed at 3 years.

Storage under unprotected conditions can result in water ingress. Water is detrimental to the appearance of the lubricant (hazy and milky) but more importantly, it affects the additive system and greatly reduces the performance level of the lubricant. It can also cause rust formation/corrosion in metal containers and subsequently in the equipment.

*Protected conditions: indoor or covered storage with no freeze/thaw cycles.

The shelf life of a grease is affected by the type and amount of thickener used, consistency of the grease, manufacturing method employed and the formulation complexity. Generally, lithium, lithium complex and calcium sulfonate complex greases remain stable for a long time. Some thickeners may have a tendency to set and harden over long storage periods (such as aluminum complex), while others may soften on aging (such as barium greases).

The shelf life of Petro-Canada Lubricants greases of NLGI grade 1 or higher is five (5) years.

Petro-Canada Lubricants greases of NLGI grade 0 or softer (#0, 00 or 000) generally have a shelf life of three (3) years. The list includes, but may not be limited to:
