名詞：
HTHS viscosity：耐剪力，越高越好
Sulphated Ash：硫酸鹽 灰，有DPF的需注意機油要有低硫酸鹽 灰，延長DPF的壽命
Total Base Number(T.B.N)：總鹼價，中和機油中的酸性物質，柴油引擎需要比較高的TBN，還得視抗衰性

The main physical and chemical requirements for ACEA A3/B3 are shown below:

Requirement	Method	Unit	Limit
HTHS viscosity	CEC L-36-A-90	cP	≥ 3.5
Sulphated Ash	ASTM D874	%wt	≤ 1.5
Phosphorus	ASTM D5185	%wt	Report
Sulphur	ASTM D5185	%wt	Report
Evaporation loss (NOACK)	CEC L-40-A-93	%	≤ 13
Total Base Number	ASTM D2896	mgKOH/g	≥ 8.0

ACEA C3 oils are typically SAE 5W-30 or SAE 5W-40 based on API Group III base oils. The main physical and chemical requirements for ACEA C3 are shown below:

Requirement	Method	Unit	Limit
HTHS viscosity	CEC L-36-A-90	cP	≥ 3.5
Sulphated Ash	ASTM D874	%wt	≤ 0.8
Phosphorus	ASTM D5185	%wt	≥ 0.070 and ≤ 0.090
Sulphur	ASTM D5185	%wt	≤ 0.3
Evaporation loss (NOACK)	CEC L-40-A-93	%	≤ 13
Total Base Number	ASTM D2896	mgKOH/g	≥ 6
