这一点你又错了!我回复过:我严重怀疑是说明书搞错了。全程我都没和你讨论过认证问题对不对。国4以前在早要求用CF什么的,过后A3B4。轻柴一直有个标准,剪切值必须大于3.7以上。A5B5的机油要求剪切值小于3.5以下(为了燃油经济性)。A5B5的机油剪切值大于3.7的至少我在狗东真心没找到,本楼不是也有个所谓的柴索车主说他一直用A5B5么!说国5要求C3。B5和C3差不多都是低灰低碱。我只想问他高转下发动机声音散不散,国5柴油用A5B5,一是PDF容易坏,二是有拉缸风险。至于粘度问题:C3现在降低粘度(为了节能减排)但是剪切值达标。A5B5也有稍高粘度的机油但是剪切值不满足柴油车

Ford WSS-M2C913-C
Fully backwards compatible and is strongly recommended for all applications that currently require the specification Ford M2C913-B. The new engine oil provides various benefits to the customer such as improved fuel economy benefits and high robustness to biodiesel fuels.
Ford WSS-M2C913-D
Introduced in 2012, oils meeting this specification are recommended for all Ford diesel engines except Ford Ka TDCi models manufactured before 2009 and Ford Galaxy 1.9 TDi models manufactured between 2000 and 2006. A product meeting this specification is especially recommended for diesel engines where M2C913-B or M2C913-C oils were initially required. An oil meeting this specification must be used in Ford Transit vehicles manufactured from 2012 onward with Duratorq 2.2 engine. Oils meeting this specification can be used with extended oil change intervals and are also suitable to be used in engines running on biodiesel or high sulfur diesel.
Ford WSS-M2C917-A
Viscosity SAE 5W40 engine oil for pump injector diesel engines.
Ford WSS-M2C934-A
Extended drain engine oil for vehicles equipped with diesel particulate filter (DPF).
Ford WSS-M2C937-A
Special engine oil for Ford Focus RS. Viscosity should be SAE 0W-40.
Ford WSS-M2C948-B
Largely based on the ACEA C2 oil sequence this spec requires a low SAPS 5W20 oil and is primarily designed for the 1.0 liter, 3-cylinder EcoBoost engine. Contains in-house tests for fuel economy and piston deposit control. Oils meeting this spec must provide a 0.9% fuel economy improvement over regular 5W-20 oils.
