For over the better part of the last century advances in lubrication technology has improved oil protection to the point that the 3,000 mile oil change is a thing of the past. In fact many automakers now actively measure the oil quality in the crankcase and vary change intervals according to usage and perceived quality. It is not uncommon to see factory recommended oil changes of 10,000 or more miles.
But we all know that old habits die hard. Many automaker have shifted from traditional dino oil to modern day synthetics with longer change intervals. These custom blended lubricants have a host of advantages, but at a pretty steep price. Are they worth it?
So are you still trusting your oil changes to traditional oil, or are you buying into the hype of synthetic changes at longer intervals? How about a combination of both?
