Synthetic oil products once got quite a rap for leaking so soon after they’re put in the tank. Early products were known to contract or swell the seals, which later cracked after a change back to regular oil. However, even with the widespread use of synthetic oils today, misconceptions about their intended use have still persisted to varying degrees of accuracy. Thankfully, the most avid of gearheads can cross that bridge and set things straight.
Some repair shops claim that you should have an oil change every 3,000 miles. However, improvements in oil technology have enabled the development of lubricants with much longer service intervals.

You may have also heard people say that once your oil is black, it’s time to change it. Experts say this is a downright myth because oil is meant to get dark—different additives alter the oil’s color, and some do so very early in the oil’s lifespan. The bottom line, according to experts, is that black oil still has plenty of service life left in it.
