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公里就換機油已經不適合現代的汽車了.浪費錢而已.
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.
油品質及引擎技術的提升7500-10000麥來換都適合多數的車.

每5千準時去換,又用保養廠推薦的雜牌沒認證的油,只會被笑是潘仔.
