In my 1984 AMC Eagle, those frequent oil changes were needed. In my 2008 Ford Focus, a longer interval is needed. The 3000 mi interval was based on good info. However, now it is based on greed. Jeff

Good info based upon old technology (oil from 25 years ago and car manufacturing from 25 years ago). Even without the 'greed' factor, the technology has changed enough that the old rules simply should not apply. ....and for the people driving the 25+ year old cars, the 'topping off what leaks out method' probably is as good as doing oil changes (though the filter probably still needs to get changed).

Gotta love the way a little article would generate so much banter. As for the high efficiency oil filters, what would be a good brand to go with? Is the stock honda filter a good choice to stick with?

While eveyone should make their own decisions on this, I can think of a few "reasonable" reasons why it is useful to at least let people know 3000 mile oil changes are not usually beneficial: 1) To counteract the constant din from compnies like Jiffy-Lube that have brainwashed gnerations of people into thinking you must change your oil every 3000 miles. 2) To make people aware that cars and oils are much better than was the case when their Fathers used to change their oil. 3) Becasue some people are concerned about the environement and don't like seeing all that perfectly good oil being drained from engines. 4) Just becasue we want people to know the facts so they can make an informed decision.

We probably keep our cars longer than most people. 8-10 years for us is not unusual. And I want minimum trouble. I use the oil change interval recommended by the maker, no matter what an oil analysis might indicate. If I err, it tends to be on the side of changing sooner than later. But as you say, everyone must make that decision for himself. It's your car, do what you want with it. |
