Your car's Engine oil

[dr. d]

I suggest buying the cheapest synthetic oil from a legit seller. Change oil and filter max every 6 months or check your owners manual na lang po for the recommended interval. Mas mura po ang langis keysa engine.

an auto authority once said,
use cheap ordinary mineral oil and change it every 5000 km or 6 months.
replace oil filter every other oil change.
expect your car's engine to last 500K km or more.
use synthetic oil if you want to splurge.
