Stop Changing the Oil Every 3,000 Miles Already!
By Brad Tuttle @bradrtuttleDec. 19, 20113 Comments
The Los Angeles Times spells out the fact that the 3,000-mile mantra just
doesn’t apply to modern-day vehicles, and that changing the oil every 3,000
miles often means paying two or three times more than is necessary:
5000公里就换机油已经不适合现代的汽车了.浪费钱而已.
Improvement in oils, friction proofing and car engines have lengthened the
oil-change interval, typically 7,500 miles to 10,000 miles for most vehicles.
油品质及引擎技术的提升7500-10000麦来换都适合多数的车.

每5千准时去换,又用保养厂推荐的杂牌没认证的油,只会被笑是潘仔.
