Maintaining your Genesis G90 is about more than just taking care of a luxury car; it’s about preserving peak performance and efficiency. The twin-turbocharged V6 engine under the hood is a feat of engineering, designed to deliver power, smoothness, and reliability. But even the best engines demand proper care, and choosing the right motor oil is one of the most important steps you can take. From understanding the recommended oil type to knowing the correct oil capacity and change intervals, ensuring the health of your Genesis G90’s engine starts here.
Key Vehicle Specifications
The Genesis G90 comes equipped with a 3.5-liter twin-turbocharged V6 engine, generating 375 horsepower at 5,800 RPM and 391 lb-ft of torque at 4,500 RPM. This precision-tuned powerhouse is paired with an 8-speed shiftable automatic transmission and an all-wheel-drive system, creating a smooth yet responsive driving experience.
These specs make the G90 more than just a luxury sedan—it’s a performance machine built to deliver high levels of reliability and power. However, the complexity of this drivetrain means you need to stay on top of its maintenance to keep these systems running smoothly. The engine’s advanced components require specific oil to maintain performance and longevity, which makes understanding its oil requirements essential.
Oil Change Essentials
Oil Type, Capacity, and Change Interval
Using the correct oil type is critical for this vehicle’s engine health. The Genesis G90 requires synthetic motor oil for maximum protection and efficiency. Synthetic oils are engineered to maintain stability under extreme temperatures, provide superior wear protection, and improve engine performance compared to conventional oils.
For this specific model, the recommended oil is 0W-30 synthetic motor oil, which ensures proper lubrication for the engine’s internal components and meets the demands of its advanced design. When you perform an oil change, the engine will need 7.4 quarts of oil to operate at its best.
As for the oil change interval, it’s wise to follow the manufacturer’s guidelines, which typically recommend replacing your oil every 7,500 to 10,000 miles or every 12 months, whichever comes first. If you want to determine the most accurate interval for your usage, consider conducting an oil analysis. This test evaluates the condition of the oil and helps you adjust your maintenance schedule based on your driving habits and engine performance.
Synthetic vs. Conventional Oil
While conventional oil might seem like a cost-effective option, it’s no match for synthetic oil in critical areas like longevity, performance, and engine protection. Synthetic oils offer:
- Better wear resistance and durability.
- More consistent performance in extreme temperatures.
- Reduced deposit buildup to keep your engine clean.
- Longer intervals between oil changes, saving time and money.
Conventional oils, by contrast, are less refined and more prone to breakdown, especially under the high-performance demands of a twin-turbocharged engine. For the Genesis G90, synthetic oil is the clear choice to ensure optimal performance and protect your vehicle’s long-term value.
Product Reviews
If you’re deciding which synthetic oil to use, there are two highly rated options worth considering:
- Mobil 1 Advanced Fuel Economy Synthetic Motor Oil 0W-30
- Pros: Proven fuel efficiency, excellent cold-weather performance, and wide availability.
- Cons: Slightly higher cost compared to conventional alternatives.
- Best For: Drivers looking to balance cost with improved engine protection and performance.
- AMSOIL Signature Series 0W-30 Synthetic Motor Oil
- Pros: Outstanding wear protection, extended drain intervals, and industry-leading performance.
- Cons: Limited availability in retail stores; higher upfront cost.
- Best For: Drivers prioritizing maximum engine protection and extended maintenance intervals.
Both oils meet the engine’s requirements, but AMSOIL stands out for its higher performance thresholds, particularly if you’re looking to go longer between oil changes.
