和我新加坡騎機車的朋友聊天聊到台灣5期法律和車上必配的裝置後...
他和我說了,很多機車用油,5期的機車不能用了...
我傻眼,問他為什麼.
原來,他是在新加坡某汽車廠工作的, ZPPD 對含氧偵測器會產生不良影響...
含氧偵測器...? 不是5期的新東西嗎 ??
去GOOGLE 查後才發現:
Why were zinc levels lowered?
AmsOil Zinc levels were lowered in response to the American Petroleum Institute (API) SM and International Lubricants Standardization and Approval Committee (ILSAC) GF-4 oil specifications. The action was driven by original equipment manufacturers (OEM) based on the Environmental Protection Agency (EPA) mandate that emissions reduction systems needed to function for a specific period of time without failing. OEMs pushed to remove anything in motor oils that could potentially harm emissions reduction systems.
Pure Power! There are concerns that phosphorous/zinc may have a gradually crippling effect on catalytic converters, although there is no available data established that indicates how long it may take, nor how much oil consumption is involved to reach that point.
Torco Oil in the engine crankcase is constantly changing to vapors and is pulled by vacuum past the rings into the intake fuel air system. These vapors containing the element phosphorus contact the exhaust oxygen sensors and the catalytic converter. Because phosphorus is both heat-seeking and deposits residue at the same time, it changes the catalytic converter's ability to break down hydrocarbon fuel-type molecules, negatively affecting the oxygen sensors and catalytic converter operation.
What API designations have reduced zinc?AmsOil There has been a stepwise reduction in sulfur and phosphorus in API oil specification designations, which drove the reduction in ZDDP content. The current API SM gasoline motor oil specification limits phosphorus to a maximum of 0.085 percent. Sulfur is limited to a maximum of 0.50 percent for 0W-20/0W-30/5W-20/5W-30 and 0.70 percent for 10W-30 viscosity categories.

簡單說就是:
1) ZPPD 對含氧偵測器會產生不良影響...
2)API 為了不要讓車裡的電子環保機關太早掛點(含氧器+觸媒),才把ZPPD 的量減少的...
所以,以我個人的判斷,5期機車只能用API SL/SM 的油, JASO 標準的完全沒說ZPPD 量要在多少以下...
騎5期的朋友,你們要用機油時,請自己注意一下了...
用 SG/SH/SJ 是對車引擎沒問題,可是對含氧偵測器...有可能會讓它加速掛掉...
含氧偵測器,如果只是象火心塞一樣便宜就好了,問題一顆要價破千的...
大家來討論一下吧...5期是台灣的未來,不理也不行...
