Selecting the right oil viscosity is critical for the 2022 Lexus IS350’s 3.5-liter V6. The factory recommendation is 0W-20, which ensures proper oil flow during cold starts while maintaining a protective film at high operating temperatures. Using a non-synthetic or incorrect viscosity can lead to increased friction, reduced fuel economy, and accelerated engine wear. The AMSOIL Signature Series 0W-20 is formulated to withstand the extreme thermal stress of the IS350’s V6 engine, ensuring that the oil remains stable even during spirited driving or extended highway commutes. Furthermore, the oil filter is a crucial component of the lubrication system; AMSOIL oil filters are tested to capture 99% of contaminants at 20 microns, far outperforming many standard filters to keep the engine clean and reduce wear on critical components like the VVT-i system.
Transmission fluid is often overlooked until a problem arises, but regular maintenance with the correct synthetic fluid is vital for the longevity of the IS350’s automatic transmission. The vehicle may come equipped with either a 6-speed (A760H) or an 8-speed (AA81E) automatic transmission. Both benefit significantly from the use of high-quality synthetic fluid that resists shear and oxidation. AMSOIL’s Fuel-Efficient Automatic Transmission Fluids are designed to reduce internal friction, which can help maximize the transmission’s efficiency and longevity. For vehicles with higher mileage, the extended life of synthetic fluids means that fluid changes can be performed less frequently, saving time and money while keeping the transmission shifting smoothly.
Differential and Cooling System Care
The rear differential of the IS350 requires specific attention, especially for Limited Slip Differential (LSD) models. The factory often specifies a 75W-85 viscosity for the rear unit, which is lower than many standard gear lubes. Using a fluid that is too thick can cause binding and harsh shifting, while a fluid that is too thin may not provide adequate protection for the gears and clutches. AMSOIL SEVERE GEAR 75W-85 and 75W-90 are excellent choices that meet these specific requirements and offer superior protection against wear and thermal runaway. The cooling system also plays a pivotal role in the vehicle’s health, particularly with the high-output engine. Over time, conventional coolants can degrade, leading to corrosion and poor heat transfer. AMSOIL Antifreeze & Coolant utilizes a unique poly-organic acid technology that protects aluminum heads and gaskets, ensuring the engine stays within its optimal temperature range.
About the Vehicle: 2022 Lexus IS350
The 2022 Lexus IS350 represents the fourth generation of the brand’s compact luxury sports sedan, known for its blend of dynamic handling, refined interiors, and legendary reliability. Under the hood lies the naturally aspirated 3.5-liter V6 engine (2GR-FKS), a powerplant that has been refined over many years to deliver a smooth and linear power delivery. This engine produces 311 horsepower and 280 lb-ft of torque, providing plenty of acceleration without the complexity of turbocharging. The power is sent to either the rear wheels or the sophisticated All-Wheel Drive (AWD) system, depending on the model configuration, allowing drivers to choose between pure sportiness or all-weather capability.
Inside, the IS350 continues to be a benchmark in its segment, featuring high-quality materials, supportive seats, and a driver-focused cockpit. The cabin is quiet and well-insulated, making long drives comfortable while offering an engaging experience during weekend backroad excursions. The vehicle’s reputation is built on Lexus’s tradition of quality, with the IS350 often cited as one of the most reliable luxury sedans on the road. This reliability extends to the mechanical components, provided they are maintained with high-quality fluids.
Despite its robust design, the IS350 is not without its common issues that owners should be aware of. One frequent problem is oil consumption, particularly in high-mileage examples or those with high-RPM driving habits. Over time, the piston rings can lose their seal, leading to the engine burning oil faster than normal. Switching to a high-mileage synthetic oil with enhanced additive packages can help condition seals and reduce consumption, potentially extending the engine’s life. Another common concern is carbon buildup in the direct injection and variable valve timing systems, which can lead to rough idling or reduced performance. Using a high-quality fuel injector cleaner periodically can help mitigate this issue by keeping the fuel system clean.
Rattles and squeaks from the suspension components are also reported by some owners, often caused by bushings or struts settling over time. While proper suspension maintenance is key, using high-performance lubricants on chassis points can help reduce wear and noise. Finally, the electronic throttle body can sometimes become sluggish or unresponsive due to carbon accumulation. This can cause hesitation during acceleration. Regular cleaning and the use of a dedicated throttle body cleaner can restore responsiveness. By addressing these potential issues with proactive maintenance and premium synthetic lubricants, IS350 owners can ensure their vehicle remains a reliable and enjoyable daily driver for years to come.
Maintenance of the 2022 Lexus IS350 does not need to be complicated. By adhering to recommended service intervals and using the right fluids, owners can preserve the vehicle’s performance and resale value. AMSOIL synthetic lubricants are engineered to provide superior protection, allowing for extended service intervals that align with modern maintenance schedules. Whether you are performing a basic oil change or a complete fluid flush, using the recommended products ensures that every component of your IS350 receives the care it deserves. With proper care, the IS350 will continue to deliver the luxury, performance, and reliability that Lexus owners have come to expect.
