Engine oil RAVENOL or ZIC

I’ve been using it as well for nearly 50,000 kms now in my personal car without any issues.

ZIC - Dito ako nag stay, ang tahimik sa makina, both matic and manual. Malamig din sa makina.

Ravenol user here (previously motul and shell user). So far, engine temp is 1 line lower, quieter engine, and very slightly better fuel economy. Ravenol for the Altis 2.0, yaris, and rav4.

On 2006 F800S i have used Ravenol. I tried Shell, BMW oil(Shell, basically) and Ravenol. With Ravenol- no false neutrals. At stops i was able to find neutral almost instantly... And engine sounds somewhat "greasy"

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 use Ravenol on my 1NZ and 3ZR engines.

after 2000km of running on it, i see there is quite a drop (30% from the max point). i think that is very weird...
