Nissan Frontier + 1UZ + Variable Mixer
แนวทางการเลือกน้ำมันเครื่องนะครับ
VI คือ ความแข็งแกร่งของ Film น้ำมัน
@100C Cst คือ ความข้นใสที่ 100 องศา
@40C Cst คือ ความข้นใสที่ 40 องศา
ผมใช้ วาโมลีน Max Life 10W-40
VI = 158
100 cSt = 15
ดีกว่า ปตท NGV นิดหน่อยครับ
ส่วนน้ำมันที่ดีที่สุดคือ Shell Helix Ultra 5W-40 ถ้าดูจากค่าทั้ง 2 ตัวนะครับ
รบกวนขอคำชี้แนะด้วยนะครับ ผมไปหาเจอมานะครับ
