Motor oil is one of the most important components of a car but all too often it is surrounded by myths. Knowing what's true and what's false about this vital liquid is crucial in maintaining your car, however it can sometimes be difficult to separate fact from fiction.<\/p>\n
One of the most pervasive misconceptions surrounding motor oil is how often it needs to be changed. Most people abide by the rule that you should change it every 3,000 miles or three months – whichever you hit first. This may have been true in years past, but according to Edmunds, it's an outdated credo. There have been a lot of advancements made with motor oil and you can go by what's recommended in your auto manual. In 2010 for instance, the average recommended interval was about 7,800 miles rather than 3,000.<\/p>\n
Another common myth is that using synthetic oil is better for your car and may actually improve your fuel economy. While synthetic products are often considered a better lubricant, there is not a lot of evidence to back up any claims of improved gas mileage and the extra money may not be worth it.<\/p>\n
"There is a school of thought that says the synthetic oils are slipperier and allow the engine to spin easier – I don't know that I believe that," auto expert Ryan Stark told Edmunds.<\/p>\n
