My Personal Experience
Having used both Liqui Moly and Mobil 1 in various vehicles over the years, I can say each has its strengths depending on the use case.
In my 2018 Audi A4, Liqui Moly 5W-40 made a noticeable difference in engine smoothness. After the switch, startup noise was reduced, and the car idled more quietly. Oil consumption dropped slightly, and the engine felt more responsive, especially during cold starts.
On the other hand, for my 2010 Toyota Camry, Mobil 1 5W-30 did an excellent job, especially in summer heat. The oil held up well during extended road trips and didn’t degrade even after 10,000 miles. No sludge, no discoloration—just consistent performance.
So, while Liqui Moly feels like a luxury tailored for performance cars, Mobil 1 delivers reliable, everyday efficiency.
Design
Liqui Moly:
Liqui Moly’s design philosophy is centered around precision. Its oil formulas include MOS2 (Molybdenum Disulfide) and synthetic ester-based compounds, which provide superior lubrication, wear protection, and thermal stability. The packaging is sleek, informative, and reflects its high-end market positioning.
The company also customizes oil for specific engines—diesel, high-mileage, turbocharged—which adds a level of specialization.
Mobil 1:
Mobil 1 uses Advanced Full Synthetic Technology, engineered to perform under high-stress conditions. Their products meet or exceed all major OEM and industry standards, including API SN, ILSAC GF-6, and ACEA A5/B5.
Mobil 1’s design is universal and aimed at mass appeal. They offer High Mileage, Extended Performance, and Turbo Diesel formulas that work with most cars.
Winner: Tie—Liqui Moly is more specialized; Mobil 1 is more versatile.
