Switched from Ford Formula F to Lukoil Genesis Armortech. Routine maintenance at 180,000 km.
Throughout the car's life, the engine was filled with Ford Formula F 5W-30 oil. Although rare, there were several instances where I had to suspect the authenticity of the oil itself based on certain characteristics described in numerous online articles. This eventually led me to the conclusion that when choosing motor oil, I wanted to avoid the Russian roulette of scrutinizing the canister before buying, and instead just buy it without any fuss. Therefore, I decided to support the domestic manufacturer by testing Lukoil Genesis Armortech 5W-30, with Ford WSS-M2C-913-A/B/C/D approval.
