Engine oil ZIC or FUCHS

Personal experience ko from 15W40 Delo Gold to Zic 10W40 to 5W30 Full Synthetic sa 1.6L Diesel Accent mas naging responsive & rev happy yung makina sa 5W30 Full Synthetic kahit sa 10W40 kasi na Full Synthetic hindi siya happy parang pigil yung makina & less responsive siya.

Been using Zic on two Hyundais (Tucson, Santa Fe), and ok yung performance niya. Maintained yung cars with fully synthetic, 10k/1 year intervals. Smooth pa rin manakbo ang engine until today.

Been using that oil on my Gen 3 Montero since 2020, and ok naman, no complaints.

Better to use ZIC X7 fs oil. Korean oil.

Been using it for several years and it’s amazing for its price.

I currently use Zic 5W-20 oil in my mirage

it has around 190kms

Fuchs Titan GT1 5w30.

Fuchs is excellent oil, run it in my nismo 370z cause it has specific esters that the cylinder liners need. Don't think it's necessary BMW engines but it is very good quality oil.

Zic M9 10w40 fully synthetic ako for Honda Click. Changed oil every 2k km. 29k odo and never pa ko binigyan ng problema

Using it for 5 years, changing oil avery 8000-10000 kikomiters, enjine souns good (as for disel car)

I've posted my UOAs on TDIClub and BITOG. The factory fill was additive depleted at 5400 miles. The Fuchs 507.00 in the next fill was good for 7-7500 miles. It might have gone longer, but I changed it out in advance of a long trip. Bottom line is that preliminary evidence is that the 507 oils are inadequate for extended OCIs in the 3.0L motor.
