ACEA A3/B4 的認證是歐洲各汽車製造商如BENZ BMW VAG Porsche等成員與機油生產商,開會協定後 制定機油標準後,歐洲各汽車製造商,再依此協定標準規範,量身訂作符合自家車輛用油的機油規範 機油製造商的機油銷售區域如為歐洲區域,機油認證當然是以取得 歐洲車廠的認證 ACEA 為主,機油製造商必須一家一家車廠,各別取得每一家歐洲汽車廠商的機油認證,機油認證由各歐洲車廠自行認證 所以ACEA A3/B4機油的測試是以賓士,VAG等歐洲車廠的引擎為測試平台 下表中的 M111引擎就是使用賓士的引擎為測驗平台
德國賓士的技術文件 Sheet 215.0 Use of lubricating oils http://bevo.mercedes-benz.com/downloadf.php?filename=en/BB00.40-P-0215-00A.pdf 1. Brand name, viscosity class and oil quality Details on the specified type and quality of oil are included in Sheets 221.0, 223.1/.2 and 231.0 to 231.3. The brand name clearly defines the product, the oil qualities are clearly specified. The designations on the lubricant containers must therefore accurately match the brand names approved by us.
文中另一段話如下 The approval is canceled whenever changes are made to the tested product. 通過 MB229.5機油認證的機油及其他認證的油品,一但改變配方,認證立即取消,更證明了 有MB229.5認證的機油配方不會輕易改變,一改變就要重新送賓士認證了!
機油的銷售區域如為北美地區,遵守北美法規機油商須取得API 認證, 北美地區(美國 加拿大 )的 API 認證則是由美國的汽車製造商,FORD福特, GM, TOYOTA, NISSAN..等,車廠與機油商共同制定 API 甜甜圈 認證標準,機油的測試是以北美車廠的引擎為測試平台,統一由 API 來執行機油認證
Overview ACEA A1/B1 oils are Mainline lubricants. They are designed for use in gasoline and light duty diesel engines that have been specifically designed to use a low viscosity oil. ACEA A1/B1 oils are typically used in older vehicles as they do not provide the minimum performance demanded by the latest OEM specifications. These oils may be unsuitable for use in some engines.
