2015 Kenworth 310: Quick Overview
- Engine Options: The 2015 Kenworth 310 typically offered a range of robust diesel engines to suit various vocational needs. Common options included PACCAR PX-7 and PACCAR PX-9 engines, as well as Cummins ISB and ISC engines. These engines are renowned for their torque and pulling power.
- Horsepower: Horsepower ratings generally ranged from approximately 200 hp to over 300 hp, depending on the specific engine and configuration chosen. Higher horsepower variants were available for more demanding applications.
- Fuel Economy: Fuel economy figures for heavy-duty vocational trucks like the Kenworth 310 are highly variable and depend significantly on the engine, transmission, load, terrain, and driving style. It is not typically rated by the EPA in the same way as light-duty vehicles. Owners often report mileage in the 6-10 MPG range under load.
- 0-60 Times: 0-60 mph times are not a standard metric for this class of vehicle and are not generally published. These trucks are built for work and torque, not acceleration.
- Towing Capacity: Towing capacity is highly dependent on the specific chassis configuration, axle ratings, and fifth-wheel or hitch setup. The Kenworth 310 is designed for a variety of heavy-duty towing and hauling applications, with capacities often exceeding 30,000 lbs for conventional towing and significantly more for fifth-wheel or gooseneck applications, especially in custom vocational builds.
- Trim-Level Features: Kenworth typically offers a range of configurations rather than distinct trims for its vocational trucks. Features would vary based on the intended application (e.g., dump truck, flatbed, service truck). Common features include robust chassis, heavy-duty suspensions, various axle configurations, durable interiors designed for work environments, and a wide array of optional vocational equipment such as PTOs, hydraulic systems, and specialized body mounts.

What Problems Does the 2015 Kenworth 310 Have?
While the 2015 Kenworth 310 is generally known for its robust construction and long-term reliability, like any heavy-duty vehicle, it can experience certain issues. Owners have occasionally reported problems related to the exhaust gas recirculation (EGR) system, especially in diesel engines, which can lead to reduced performance and increased emissions if not properly maintained. Another area to monitor can be the transmission, particularly if the truck has been subjected to severe duty cycles or improper shifting techniques. Electrical gremlins, such as intermittent sensor failures or issues with dashboard warning lights, can also surface over time, though these are often addressable with thorough diagnostics. Drivetrain components, including U-joints and driveshafts, may require attention due to the heavy loads they often carry.
Regarding recalls, it is essential for owners to check the National Highway Traffic Safety Administration (NHTSA) website or consult with a Kenworth dealer using the truck's VIN for any outstanding recalls specific to the 2015 model year or its components. Recalls can affect various systems, from braking to emissions.
Long-term reliability is a strong suit for Kenworth, but it is heavily dependent on consistent and proactive maintenance. Neglecting regular oil changes, filter replacements, and fluid checks can exacerbate wear and lead to more significant issues down the line. The 2015 Kenworth 310, when well-maintained, is expected to provide many years and hundreds of thousands of miles of service. However, specific issues could arise depending on the engine manufacturer chosen (e.g., PACCAR vs. Cummins) and the vocational application the truck was used for. For instance, trucks used in construction or off-road applications might experience more wear on suspension and undercarriage components compared to those used in highway hauling.

How long will the 2015 Kenworth 310 last?
The 2015 Kenworth 310 is built for longevity, and with diligent maintenance, it's not uncommon for these trucks to surpass 500,000 miles, with many exceeding 750,000 miles or even reaching the million-mile mark. Owner data and common industry benchmarks suggest that a well-maintained Kenworth 310 can offer 10-15 years of service life. The long-term durability is a testament to Kenworth's robust engineering and high-quality components. Weaknesses that may emerge over extensive mileage often pertain to wear and tear on drivetrain components, suspension parts, and potential issues with complex emissions systems if not regularly serviced. However, the core chassis and engine block typically remain strong for hundreds of thousands of miles.
What Technology & Safety Features are Included?
The 2015 Kenworth 310, being a vocational truck, prioritizes functionality and driver practicality over cutting-edge infotainment and advanced driver-assistance systems found in consumer vehicles. Its built-in technology is primarily focused on operational efficiency and safety.
Standard Features: Standard technology typically includes a functional instrument cluster with essential gauges and warning lights, an AM/FM radio, and basic climate controls. Connectivity options are usually limited to auxiliary inputs for external devices. Safety features commonly include robust anti-lock braking systems (ABS), sturdy seat belts, and durable construction designed to withstand demanding operational environments. Visibility is generally good due to the conventional cab design, which aids in maneuvering in tight spaces.
Optional Features: Optional features were more extensive and catered to specific vocational needs. These could include upgraded audio systems with CD players, Bluetooth connectivity for hands-free calling, and navigation systems. For driver assistance, options might have included things like auxiliary lighting packages and more advanced mirror configurations for enhanced situational awareness. Some models could be equipped with electronic logging device (ELD) interfaces.
Safety Ratings: Crash-test ratings for heavy-duty vocational trucks like the Kenworth 310 are not conducted or published by organizations like the NHTSA or IIHS in the same way as passenger cars and light trucks. The safety of these vehicles is primarily ensured through adherence to stringent federal motor vehicle safety standards (FMVSS) and their inherent robust construction, designed to protect occupants in severe operational conditions rather than typical collision scenarios. Kenworth trucks are engineered with a strong emphasis on structural integrity and driver protection, including reinforced cab structures and advanced braking systems.
