之前有人提過說在 Viscosity cSt @ 40°C 要低於 60 才適用於原廠機油幫浦,這到底有無原廠的定義或是有一標準規範?
像是 Maxima K2 這支油原廠網頁就寫著:
Formula K2 is ideally suited as a premix with pump or race gasoline
in virtually all high performance and racing 2-cycle engines.
上文意思是說這款油能用幫浦也能預混,而其數據表示40°C = 97 ; 看到時有很大的疑問?!
Viscosity cSt @ 40°C 97
Viscosity cSt @ 100°C 13.58
Pour Point °F -25
Flash Point °F 240
Fire Point °F 280
Viscosity Index 140
SAE Viscosity 40
