CarAndDriver之前做的一個Regular or Premium Gas的討論與實驗,很有趣! http://www.caranddriver.com/features/regular-or-premium 最主要還是看引擎:
1、有沒有Knock Sensor 2、ECU的程式設計
舉V6雅歌為例:用92(Regular 87)反而比95(Premium 91)更適合!原文如下:
A Honda Accord V-6 with VTEC variable valve timing represented the mainstream-family-sedan class, .... ....Accord took a tiny step backward in power (minus 2.6 percent) and performance (minus 1.5 percent) on premium fuel, a phenomenon for which none of the experts we consulted could offer an explanation except to posit that the results may fall within normal test-to-test variability.
