Engine oil ZIC or OEM FORD

Used zic for several years with no issues. This year lang ako nagpalit ng ibang brand since nagmahal na zic dun sa suking auto supply ko.

I’ve been using zic oil for 6 years now. Ok naman I did not experience any issue.

On a side note, if anyone really wants to see what their oil change interval should be, just get an actual oil sample analysis done. Per the lab reports, I can get 8k miles on quality synthetics and still have a good safe margin for oil life.

Ford is telling me to change oil at my Focus every year or every 15000km (9300 miles)

I red-line 1st and 2nd gear when merging onto highways from the on-ramp. But then cruise at 100 kmph on the right lane. Gotta have fun when you can! Ensure that **oil** temps are good, not just the coolant.
