之前車剛到手的時候前車主機油選用15w40油品10000km更換一次
但這10000km前後時間卻長達2年的時間,所以接手後先照原廠手冊
CD級以上10w40油品,那時候剛好是冬天所以找了CF10W40中階油品
洗引擎用,打算開個幾千KM就換掉,原本車上漏下來的油~黑到不行
自己換的10W40也很黑,所以打算繼續用這支在洗一次,直到前陣子
渦輪掛點換渦輪後發現引擎溫度比之前高很多,所以機油順便更換
CG4 15W50的油品對應夏天的氣溫跟更高的引擎溫度應該比較合而
這幾趟開下來發現水溫一樣高,但機油要達到工作溫度的速度真的
好像慢了很多,以前市區晃一下油就熱開最近一樣的路線上了高速
公路還要開個10來分鐘油才熱開~後來看了一下新款柴油增壓引擎
用油號數0W30 5W30一大堆以往認為這類油品應該都是汽油引擎用
柴油車壓縮比至少2X:1起跳又有渦輪增壓,引擎溫度一整個高才是
15W50的油會熱不開,讓我有點驚訝之外,也開始考慮低號數油品但
又怕早期的引擎技術跟精度跟現在新引擎有落差,換用低黏度油品
會造成失油大增或是機件異常磨損的問題,又有勞前輩開釋一下^^

車不用快,雙缸則名,缸不在大,一百則靈,斯是國產,萬轉也行。
懸吊有阻尼,彎道才穩定,管你上南橫或攻武嶺,一樣輕鬆寫意。
雙碟配單槍,對四配雙缸,前後積匹阿七零,隨時準備rv看風景。
路上阿伯云:少年耶,哩街甘係喜進靠二五零!係再時髦又帥氣。
臨檢條唄云:少年耶,哩街甘係國產一五零?實在有點膽戰心驚。
