Purolator: Filter choice crucial when changing oil

Automotive filter manufacturer Purolator says that most car owners know that they need to change their vehicle’s oil and filter periodically, even though they may not always follow the recommended OEM schedule. 

The type of oil their car needs is usually easy to figure out. It is specified in the owner’s manual, which will indicate both the quality and viscosity of the recommended engine oil.

“While oil characteristics are often discussed rarely is the choice of an appropriate filter ever addressed – when, in reality, the filter’s features should be selected based on the oil chosen, expected driving conditions, and planned service life,” said Chuck Kerrigan, director of marketing for Purolator.

Purolator says the quality of oil required in a particular car needs to meet standards set either by the American Petroleum Institute (API) or the International Standardization and Approval Committee (ILSAC), a joint effort of U.S. and Japanese automobile manufacturers. The necessary grade is specified in the owner’s manual and printed on oil bottles.

The recommended viscosity (thickness) of the oil can also be found in the owner’s manual, and is typically identified as meeting standards set by the Society of Automotive Engineers (SAE). A typical multi-grade oil is SAE 10W-30, which acts like thinner 10-weight oil in the winter, when thinner oil promotes easier starting and like thicker 30-weight oil in the summer when added protection is needed.

There are two kinds of oils – conventional and synthetic. Conventional oil is the one that we have been using in our cars for the past several decades and which – ideally – we are told should be changed every 3,000 miles.

Synthetic oil, on the other hand, has been developed in scientific labs and is specified by many vehicle manufacturers for use in their cars. Synthetic oil is designed to last for up to 10,000 miles. However, it is significantly more expensive than conventional oil.

Purolator recommends that Based on these measures, motorists that change their car’s engine oil frequently may select from Purolator Classic or PureONE oil filters. A good overall oil filter, the Purolator Classic, on average, can capture 97.5% of particles larger than one thousandths of an inch in diameter, says Purolator.

A step up, the Purolator premium PureONE oil filter can capture, on average, 99.9% of these same particles. So, both types of Purolator oil filters can efficiently remove most particles that can potentially damage internal engine components.

“For vehicles where the manufacturer recommends the use of synthetic oil and extended drain intervals, it is appropriate to use a filter that is specially designed for use with synthetic oils to avoid degradation of the filtering function and failure of one or more internal filter parts or valves,” said Kerrigan.

The recently introduced Purolator Synthetic oil filter is custom-engineered to help motorists take advantage of the extended life offered by synthetic oils. Purolator Synthetic utilizes 100% synthetic media with pleat support technology containing wire backing providing increased stability. This filter can capture and hold more contaminants over the longer life of synthetic oils – up to 27 grams, without getting clogged.
