ACEA A3/B4 oils are Upper Mainline lubricants. They are designed for a use in high performance gasoline and light duty diesel engines(汽油柴油引擎皆可用) and are typically used in newer vehicles as they provide the minimum performance demanded by many OEM specifications.
ACEA A3/B4 oils are probably seen in the widest range of viscosity grades. The most common being:
•SAE 10W-40 based on a mix of API Group I and Group III, or API Group II base oils. •SAE 5W-40 and SAE 5W-30 based on API Group III base oils. •SAE 0W-30 based on API Group IV base oils.
Lubrizol 的ACEA A5/B5 規格 ACEA A5/B5 oils are Upper Mainline lubricants. They are designed for use in high performance gasoline and light duty diesel engines (汽油柴油引擎皆可用) that are specifically designed to use a low viscosity oil. These oils may be unsuitable for use in some engines.
ACEA A5/B5 oils are typically low HTHS (≤3.5cP) SAE 5W-30 based on API Group III base oils. 大部份 A5/B5 機油 普遍都是 高溫高剪切黏度 小於或等於 3.5cP SAE黏度 5W-30 是由 第三類基礎油所調配的(題外話.... 有些大大認為第三類基礎油調配的機油 比第四類基礎 PAO 不耐用)
