All Oil Is Not the Same

In a recent studio, AAA found that synthetic oil outperformed conventional oil by an average of nearly 50 percent, offering vehicles significantly better engine protection for only $5 more per month when following a factory-recommended oil change schedule. To protect vehicle engines, particularly those that operate in extreme conditions, AAA urges drivers to consider a switch to synthetic oil at their next oil change service.

“Oil protects critical engine components from damage and AAA found that synthetic engine oils performed an average of 47 percent better than conventional oils in a variety of industry-standard tests,” said John Nielsen, AAA’s managing director of Automotive Engineering and Repair. “With its superior resistance to deterioration, AAA’s findings indicate that synthetic oil is particularly beneficial to newer vehicles with turbo-charged engines and for vehicles that frequently drive in stop-and-go traffic, tow heavy loads or operate in extreme hot or cold conditions.”

Switching from a conventional oil to a synthetic oil will cost the average driver $64 more per year, or an extra $5.33 per month. A survey of AAA’s Approved Auto Repair facilities reveals that the average cost of a conventional oil change is $38, while a synthetic oil change is $70. For those that change their vehicle’s oil themselves, the average cost of five quarts of conventional oil is approximately $28, while synthetic oil is $45. AAA’s survey also shows that vast majority (83 percent) of service professionals select synthetic oil for their personal vehicles.

AAA’s engine oil research focused on eight industry-standard ASTM tests to evaluate the quality of both synthetic and conventional engine oils in terms of shear stability, deposit formation, volatility, cold-temperature pumpability, oxidation resistance and oxidation-induced rheological changes. At the time of testing, all tested oils were licensed by the American Petroleum Institute and advertised to meet the International Lubricants Standardization and Approval Committee’s GF-5 specifications.
