: : Stop Changing the Oil Every 3,000 Miles Already!

: : 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.
: 補個戰點
: 現在歐美都用5w30 5w20
: 台灣用5w40 5w50保護性才夠 v.s. 那個太黏 5w30 5w20保護性一樣但更省油
: 用這保護性更好更不會熱衰 符合原廠規範即可
: 台灣環境特殊濕熱走走停停 車廠認證、甜甜圈
