preference and budget lang mag determine kung anu bibilin para sa auto.

kapag cold weather(winter) 15w40 won't flow even 10W will have a hard time before flowing,

"the difference will be in fuel efficiency, 0W/5W are more fuel efficient compared to higher grades"
tanong ko lang Sir.

yung "cold" viscosity ng 0w40 na Mobil ay 75 cSt, "hot" naman ay 13.5 cSt

yung sa 15w40 na Mobil din ang "cold" niya 109 cSt, "hot" naman ay 14.5 cSt

kung marginal lang ang difference during cold flow, ilang percentage ba ang pinagkaiba ng 75 cSt sa 109 cSt?

base kasi dun sa datasheet, halos same lang sila ng viscosity during operating temperature. 1 cSt lang ang pinagkaiba nila.

sabi din kasi ni pareng Google, 80% ng engine wear nasa initial start up.

salamat.
