Engine oil ZIC or ELF

Been using it for several years already and very popular brand na sya ngayon since anak ni Lucio Tan ang distributor.

Use their X7 if you plan to change oil every 6 months. Use X7000 for yearly changes.

I've been putting 10w-40 ELF 70 STI regular oil in my 1.6 petrol from '98 for 3 years now with no issues.

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.

5w40 for sure, my engine sounds happier, quieter, more sound than it did when the PO had 5w30 in it. So 5w40 is a given especially since you have a lot of Km on the clock, when it comes to the brand it really doesn't matter especially if you keep the oil change intervals reasonable.

I use Elf Oil and I change mine every 5-7k miles.

I currently use ELF Exellium NF, Motul is good too I was tempted to get it....you can also check out ECS Tuning, they sell Lubro Molly now, I think that's gonna be my next choice and I might stick with it. I've used Amsoil for about 20K miles and liked it too. Otherwise, you can't go wrong with Castrol Syntec 5w40 either, I've used it since new all the way till 60K miles.

I used ELF Excellium NF 5W40.

I personnally use Elf and love it, best oil I ever used so far.

ok i just did an oil change today. i put in Elf Excellium 10W50 Full Synthetic. anyways, the difference is awesome. much more free reving and "wanting to go faster" feeling. before oil change it felt tired and revs were lazy and engine had a 'fuzzy' sound when accelerating. anyways, all is good now
