The 2018 Honda CR-V with the 2.4-liter K24W9 engine is a compact crossover known for its reliability, spacious interior, and fuel efficiency. However, like any modern internal combustion engine, it relies heavily on high-quality lubricants to maintain performance and longevity. Using the correct viscosity and specification oils is critical, especially for engines equipped with direct injection and turbocharging technologies, which are sensitive to sludge, carbon deposits, and high-temperature breakdown. This guide details the specific lubrication needs for the 2018 Honda CR-V 2.4L, ensuring your vehicle operates at its peak potential under all driving conditions.

Understanding the specific fluid capacities and types for your 2018 Honda CR-V is the first step in a proper maintenance routine. The engine oil capacity is 4.4 quarts without a filter change and 4.6 quarts when replacing the oil filter. It is crucial to check the oil level after refilling to ensure accuracy, as overfilling or underfilling can both lead to mechanical issues. The recommended oil viscosity for all temperatures is 0W-20, a specification designed to optimize fuel economy and cold-start protection while maintaining sufficient film strength at high operating temperatures.
Transmission and Fluid Specifications
The automatic transmission in the 2018 CR-V varies slightly based on whether the vehicle is Front-Wheel Drive (FWD) or All-Wheel Drive (AWD), but both utilize CVT technology requiring a specialized fluid. For the AWD models, the total fill capacity is 8.9 quarts for the CVT, while the FWD models require 8 quarts. Initial fill amounts are approximately 4.5 quarts for AWD and 3.9 quarts for FWD. Honda specifies the use of HCF-2 or VTF20 fluid, and while genuine Honda fluid is an option, AMSOIL’s 100% Synthetic CVT Fluid is formulated to outperform these requirements, offering superior frictional properties and thermal stability.
The cooling system holds a capacity of 6.6 quarts. Maintaining the correct coolant mixture is vital for preventing overheating and corrosion within the aluminum engine block and radiator. AMSOIL offers both pre-mixed and concentrated formulations that exceed original equipment requirements, protecting against rust, scale, and hose degradation for up to five years. Whether you choose the ethylene glycol or the propylene glycol variant, the result is a cleaner cooling system that prevents costly repairs down the road.
Essential Additives and Care Products
Beyond the primary fluid changes, the longevity of your Honda CR-V benefits greatly from the use of specialized additives. For gasoline engines, AMSOIL P.i.® Performance Improver is highly recommended. This additive is engineered to restore up to 14% of lost horsepower and cleans fuel injectors, particularly beneficial for GDI (Gasoline Direct Injection) engines where carbon buildup is common. It also helps reduce the need for higher-octane fuel and controls pre-ignition knock, ensuring smoother engine operation.
During the colder months or for vehicles that sit in storage for extended periods, AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, fighting varnish, gum, and ethanol corrosion. For the brake system, regular replacement with AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid ensures consistent pedal feel and prevents moisture absorption, which can lead to corrosion in the brake lines and calipers.
For general vehicle maintenance, AMSOIL Synthetic Multi-Purpose Grease is ideal for chassis components, resisting thermal degradation and providing outstanding low-temperature pumpability. When it comes to cleaning, AMSOIL Engine Degreaser effectively removes grease and grime from the engine bay, while AMSOIL Brake and Parts Cleaner cleans brake components without leaving residue that could cause squealing. These products collectively form a comprehensive care regimen for the CR-V, addressing everything from engine cleanliness to undercarriage protection.
About the Vehicle
The 2018 Honda CR-V represents the sixth generation of the world-renowned compact crossover, a segment where the CR-V has long been a dominant force. Built on Honda’s global compact car platform, the 2018 model year brought a refreshed design that balanced aerodynamic efficiency with a spacious and practical interior. The 2.4-liter four-cylinder engine, identified by the code K24W9, is part of Honda’s Earth Dreams Technology family. This naturally aspirated powerplant is designed to deliver a healthy blend of responsiveness and fuel economy, producing around 184 horsepower. Unlike the 1.5-liter turbocharged option also available in the CR-V lineup, the 2.4L K-series engine is prized for its proven reliability and linear power delivery, making it a favorite for those who prioritize mechanical simplicity and long-term durability.
Ownership of the 2018 CR-V is often characterized by its versatility. The vehicle serves as a primary daily driver for many families, offering a roomy cabin that easily accommodates passengers and cargo. Its seating position provides a commanding view of the road, while the available All-Wheel Drive system offers added confidence in adverse weather conditions. The transmission, a Continuously Variable Transmission (CVT), is tuned to maximize fuel efficiency, though drivers who enjoy a more traditional driving feel may opt for manual shift modes available in newer models or through careful management in the 2018 iteration.
Despite its strong reputation, the 2018 Honda CR-V is not without its common issues. One known problem among owners of the 2.4L engine is the potential for carbon buildup on the intake valves, a common characteristic of direct injection engines over time. Using high-quality synthetic oils and regular fuel system treatments can help mitigate this accumulation. Another issue is the potential for oil dilution, particularly in colder climates or with frequent short-trip driving, where unburned fuel can contaminate the engine oil. AMSOIL’s synthetic formulations are specifically designed to resist dilution and maintain viscosity, ensuring the engine remains protected even under these severe conditions.
Additionally, some CR-V owners have reported issues with the CVT transmission developing shudder or noise, often attributed to fluid degradation or clutch wear. The use of a dedicated high-performance synthetic CVT fluid like AMSOIL’s can help restore smooth shifting and extend the life of the transmission components. Finally, the cooling system on these vehicles can be susceptible to overheating if the coolant degrades over time, leading to potential damage to the radiator or water pump. Maintaining a robust antifreeze mix with corrosion inhibitors is a proactive step to prevent these thermal management failures. By addressing these specific areas with premium lubricants, owners can significantly enhance the reliability and performance of their 2018 Honda CR-V.
Choosing the right lubricants is an investment in the longevity of your vehicle. The 2018 Honda CR-V 2.4L is a capable and reliable machine, but it demands top-tier fluids to function as intended over thousands of miles. By utilizing AMSOIL’s full line of synthetic motor oils, filters, transmission fluids, and additives, you ensure that your CR-V receives the care it deserves, protecting against wear, corrosion, and performance loss.
