TBN 都剩下0.4
誰要用。請說一下，我這邊有廢機油。可能都高於3
大量的硫不錯啊。酸化更快。不過速克達 引擎 有什麼怕酸的機件。
看看別人怎麼說，我也來個擷取片段。

The TBN is determined by measuring the milligrams of acid neutralizer (potassium hydroxide) required to nullify all the acids present in a one gram sample of oil. Viscosity retention and TBN are very important in deciding when to change your oil. A TBN of three or less typically denotes a failure of the oil to absorb acids. Oils with a higher initial TBN are therefore better suited for longer change intervals, assuming the base oil is of sufficient quality to maintain its specified viscosity over time. The subjects of base oil quality and viscosity retention are very complex, and are discussed later.
TBN是通过测量一克油样中的酸中和剂（氢氧化钾）所需的毫克数来确定的。粘度保持量和TBN对于决定何时更换机油非常重要。TBN为3或更低，通常表示机油不能吸收酸。因此，假设基础油的质量足够好，能够长期保持规定的粘度，那么初始TBN较高的机油更适合于较长的更换周期。基础油的质量和粘度保持的主题非常复杂，将在后面讨论。
