The Chevrolet LSF is a 3,564 cc, V6 direct — injection gasoline engine produced between 2010 and 2016. Part of GM's High Feature engine family, it features dual overhead camshafts (DOHC), variable valve timing (VVT), and Active Fuel Management (AFM) for improved efficiency. In standard configuration, it delivered 207 kW (282 PS) and 347 Nm of torque, offering a balance of performance and fuel economy for mid — size and full — size applications.

Production years 2010–2016 meet U.S. EPA Tier 2 Bin 5 and California LEV II ULEV standards (EPA Certificate #EPA/FF/2010/LSF).
The Chevrolet LSF is a 3,564 cc V6 gasoline engine from GM's High Feature family (2010–2016). It combines direct fuel injection with variable valve timing and Active Fuel Management to deliver responsive performance and improved efficiency. Designed to meet stringent U.S. emissions standards, it balances everyday usability with strong mid-range power.

The Chevrolet LSF was used across Chevrolet's mid-size and full-size sedan platforms with transverse mounting and no licensed production. This engine received platform-specific adaptations-tuned intake manifolds in the Malibu and enhanced cooling in the Impala-and from 2013 the facelifted Malibu models adopted revised intake port design, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The LSF's primary reliability risk is intake manifold carbon buildup under frequent short-trip cycles, with elevated incidence in fleet and urban vehicles. Internal GM field reports from 2017 indicated approximately 16% of pre-2013 units required intake cleaning before 110,000 miles, while EPA compliance data shows AFM mode failure is common in poorly maintained examples. Extended idling and low-quality fuel increase deposit formation and lifter wear, making oil quality and fuel type adherence critical.
Analysis derived from General Motors technical bulletins (2010-2016) and U.S. EPA Light-Duty Vehicle Failure Statistics (2012-2018). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The LSF is generally robust for daily use, but pre-2013 models show higher intake carbon and AFM lifter issues under urban conditions. Later revisions with updated port design are more durable. Regular oil changes with Dexos1 5W-30 and Top Tier gasoline are essential. Well-maintained units can exceed 200,000 miles, especially in highway-driven applications.
Key issues include intake carbon buildup, AFM lifter failure, timing chain rattle, and water pump leaks. These are documented in GM service bulletins, particularly SIB 15-NA-006 for intake updates. Fleet vehicles in city environments report higher AFM and intake fault rates.
The LSF was used in the Chevrolet Malibu (2010-2016), Impala (2010-2016), and exported to Australia for the Holden Commodore VF (2013-2016). It was not used in trucks or crossovers. No passenger car applications outside mid-size and full-size sedans exist.
Yes, but with caution. ECU remaps can safely increase output by +25-40 kW on stage 1, as the block and internals are strong. However, the stock valvetrain and AFM system are limiting factors. Upgraded lifters and springs are recommended for higher power levels to prevent failure under increased RPM.
In a Chevrolet Malibu, expect 23-25 mpg (US) (~9.5-10 L/100km) on highway, and 18-20 mpg (US) in city driving. Real-world economy depends heavily on driving style. Fleet data shows average consumption of 20 mpg (US) across mixed operations.
Yes. The LSF is an interference engine, meaning piston-to-valve contact will occur if timing is lost. The timing chain system requires inspection if noise or jump is suspected to prevent catastrophic internal damage.
GM specifies Dexos1 5W-30 synthetic gasoline engine oil. Oil must be changed every 15,000 miles or as per maintenance schedule. Using non-Dexos1 oils may void warranty and increase wear in the AFM system and valvetrain.
