Engine oil Mannol or ZIC

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.

I use the mannol 5w30, it might be cheap but it's still just as slippy

Genuinely speaking, it's actually not bad oil at all. Apparently manufactured in Germany, meets or exceeds the OEM spec for my cars. In my 350Z which likes to drink oil, I change it using Fuchs Titan Race Pro S 5W-40 but I keep a bottle of this (also 5W-40) in the boot for top ups.

I run Mannol 5w30 for Japanese brands on my 202k km d16

Works fine but I might change to a slightly thicker one
