The three-thousand mile oil change rule is the old standby for protective dads and for times when other means of prediction were not available. To begin, most new off the lot vehicles when following owner’s manual guidelines can go seven thousand to ten-thousand miles before the first oil change is needed or even suggested. After that, there are different guidelines for different types of driving conditions, and being familiar not only with what type of driver you are considered to be and also with your owner’s manual can help you to safely put more time and/or miles between maintenance which means more cash in your pocket.
As this rule is ousted, be sure to read up on recommendations for other maintenance that may have previously been related to the three-thousand mile rule. One new rule that comes out of the shift is that a filter needs only to be changed every other time the lubricant is. If you are not sticking to the three-thousand mile rule, this rule is also a goner. A prevailing difficulty with this new idea is that owners previously were on top of preventative maintenance due to inspections made at regular lube-oil-and-filter checks, but a longer period of time between changes does not mean that the entire car can be ignored for longer periods of time, so be sure to stay on top of your vehicle needs regardless of the miles between changes.
The introduction over the last few decades of synthetic oils to the mass population is also a culprit for the lasting duration between preventative maintenance checks. It has been estimated by trusted scientific analysis that vehicles operating on synthetics can possibly go up to twenty-thousand miles before requiring the maintenance previously known as the three-thousand mile rule, and while this can be a responsibility load off of a car owner, again the time lapse can cause other maintenance needs to fall aside.
Today, lab analysis can be done on existing oil to make predictions about the needs of the engine lubricant. The check is comparable in cost to that of one regular change, and it can indicate, and usually does, that most drivers are apt to change the lubricant more frequently than needed. A check is not necessitated prior to every maintenance; one analysis will do if you’re driving conditions remain the same for the life of your car. If you tend to keep cars on the road until they are considered classics, the needs of the engine and other parts of the car may alter as the car ages, but for the typical driver who keeps a car from two to four years, one initial analysis of used fluid can help predict when an oil change is necessary for you.
