At Integrity Car Care & Tires, we work hard to educate our customers on the benefits of synthetic motor oil. We know the benefits of synthetic oil far outweigh the modest increase in cost. That is why the owners, managers and technicians at Integrity Car Care & Tires all run synthetic oil in our personal vehicles. Don't just take our word for it though. After extensive independent testing, AAA has come to the same conclusion. In the article linked below, AAA has "found that synthetic oil outperformed conventional oil by an average of nearly 50 percent in its independent evaluation, offering vehicles significantly better engine protection for only $5 more per month." "While only a limited number of vehicles specifically require synthetic oil, all vehicles can benefit from using synthetic oil."
