Important: Active Fuel Management (AFM) Issues in 2013 Silverados
The 5.3L and 6.2L V8 engines in 2013 Silverado 1500 trucks use AFM (also called DOD - Displacement on Demand) to deactivate cylinders 1, 4, 6, and 7 for improved fuel economy. This system is the primary cause of excessive oil consumption and lifter failures. Many owners report these issues appearing between 80,000-120,000 miles.
Common AFM Symptoms:
- - Burning 1+ quart of oil per 1,000 miles
- - Ticking or knocking noise from engine
- - Misfires on cylinders 1, 4, 6, or 7
- - Fouled spark plugs (oil-covered)
- - P0300 random misfire code
Proven Solutions:
- - Complete AFM delete kit installation
- - Updated valve cover with PCV fix
- - Range AFM disabler device
- - Lifter replacement with non-AFM parts
- - Engine rebuild with AFM delete
2013 Model Year: Last of the Second Generation
The 2013 Silverado 1500 represents the final year of GM's second-generation (GMT900) platform before the complete redesign in 2014. This makes it a mature design with well-known issues and established repair procedures. Common problems have documented solutions, and replacement parts are widely available and affordable. The 2013 model year benefits from incremental improvements made throughout the generation while avoiding first-year issues of newer designs.

Chevrolet Silverado 1500 2013
Complete Transmission Repair Guide
Expert insights on common transmission problems, repair costs, and maintenance for your Chevrolet Silverado 1500. Trusted by Sonoma County drivers since 1978.
Common Chevrolet Silverado 1500 Transmission Problems
Based on our 45+ years of experience, these are the most common transmission issues we see with this vehicle model.
5.3L V8 Excessive Oil Consumption (AFM Related)
The 2013 Silverado 5.3L V8 (LC9/LMG engine codes) with Active Fuel Management (AFM/DOD) is notorious for excessive oil consumption. GM's defective low-tension piston rings combined with the AFM system's oil spray during cylinder deactivation causes oil to pass into the combustion chamber. Class-action lawsuits have been filed against GM for this issue. Many owners report consuming 1+ quart per 1,000 miles. The problem is compounded by GM's oil life monitoring system which only monitors oil quality, not oil levels. Solutions include AFM delete, updated PCV valve cover, or engine rebuild with non-AFM components.
Common Symptoms
- •Burning 1-2 quarts of oil between changes
- •Blue smoke from exhaust on startup or acceleration
- •Low oil level warnings between oil changes
- •Fouled spark plugs (especially cylinders 1, 4, 6, and 7)
- •Oil consumption increasing over time
- •No visible external oil leaks
Immediate attention required! This issue can lead to complete transmission failure if not addressed.
5.3L V8 AFM Lifter Failure
The hydraulic lifters on AFM cylinders can collapse or fail completely, causing valve train noise and misfires. The Active Fuel Management system cycles these special collapsing lifters constantly during normal driving, leading to premature wear. Failed lifters can cause camshaft lobe damage if not addressed quickly. Repair typically requires replacing all 16 lifters, and often the camshaft as well. Most experienced mechanics recommend AFM delete during repair to prevent recurrence.
Common Symptoms
- •Ticking, clicking, or knocking noise from engine
- •Misfires specifically on AFM cylinders (1, 4, 6, 7)
- •Check engine light with P0300 random misfire or cylinder-specific codes
- •Rough idle that worsens when engine is warm
- •Reduced power and poor fuel economy
- •Metal debris found in oil during changes
Immediate attention required! This issue can lead to complete transmission failure if not addressed.
Throttle Body and TPS Failure (Reduced Engine Power)
The electronic throttle body and throttle position sensors are common failure points on the 2013 Silverado. The infamous "Reduced Engine Power" message indicates the ECM has detected a problem with the electronic throttle control system. Common causes include dirty or failed throttle body, faulty TPS, damaged wiring harness (especially ground connections), or accelerator pedal position sensor failure. Carbon buildup can cause issues even before component failure. Regular throttle body cleaning every 30,000 miles helps prevent problems. See our complete guide at /blog/reduced-engine-power-chevy-silverado-complete-guide
Common Symptoms
- •"Reduced Engine Power" warning message on dash
- •Engine enters limp mode (limited to 20-30 mph)
- •Erratic idle speed or stalling
- •Poor throttle response or no response
- •Check engine codes P0120, P0122, P2135, P1125
- •Issue may be intermittent initially, then constant
4.8L V8 - Most Reliable Option (Without AFM)
The 4.8L V8 (L20 engine code) is generally considered the most reliable 2013 Silverado engine because it does NOT have Active Fuel Management (AFM). Without AFM, the 4.8L avoids the oil consumption and lifter failure issues that plague the 5.3L and 6.2L engines. With 302 horsepower, it provides adequate power for most uses while offering better long-term reliability. If buying a used 2013 Silverado, the 4.8L is often the safer choice.
Common Symptoms
- •Fewer major problems than 5.3L
- •No AFM-related oil consumption
- •Standard lifter design less prone to failure
- •Lower repair costs when issues occur
Intake Manifold Gasket Leak
The plastic intake manifold gaskets on the 2013 Silverado can fail, allowing coolant to leak internally. This can cause engine overheating, head gasket damage, and potentially catastrophic engine failure if coolant mixes with engine oil. The 4.8L and 5.3L are particularly susceptible. Early detection is critical - watch for any coolant loss without visible external leaks. Repair involves replacing intake manifold gaskets with updated design.
Common Symptoms
- •Coolant loss with no visible external leak
- •White smoke from exhaust (coolant burning)
- •Rough idle and intermittent misfires
- •Sweet coolant smell from engine bay
- •Engine overheating episodes
- •Milky residue under oil cap (coolant mixing with oil)
Knock Sensor Failure
Both the 4.8L and 5.3L commonly experience knock sensor failures. The knock sensors are located under the intake manifold, making replacement labor-intensive (4-6 hours). Symptoms include reduced performance as the ECM retards timing to protect the engine. Failed knock sensors can also cause the transmission to shift poorly due to reduced engine output.
Common Symptoms
- •Check engine light with codes P0325, P0327, P0332
- •Engine knocking or pinging under load
- •Reduced power and poor acceleration
- •Poor fuel economy
- •Engine timing excessively retarded
Fuel Pump Module Failure
The in-tank electric fuel pump can fail without warning, leaving you stranded. Early symptoms include extended cranking times or power loss under heavy acceleration. The fuel pump module includes the fuel level sending unit, so fuel gauge issues often accompany or precede pump failure. Replacement requires dropping the fuel tank. Consider replacing the fuel filter every 30,000 miles to extend pump life.
Common Symptoms
- •Extended cranking time before starting
- •Engine stalling at idle or low speeds
- •Loss of power during acceleration or under load
- •Whining or humming noise from fuel tank area
- •Check engine light with fuel pressure codes
- •Complete no-start condition (sudden failure)
Water Pump Failure
Water pump bearings and seals commonly fail on 2013 Silverado engines, typically between 80,000-120,000 miles. Early warning signs include a weep hole leak at the pump or bearing noise. If the pump seizes or the impeller fails, severe overheating and engine damage can occur within minutes. Preventive replacement around 100,000 miles is recommended.
Common Symptoms
- •Coolant leak from front of engine
- •Whining, squealing, or grinding noise from water pump area
- •Engine overheating
- •Steam from engine bay
- •Coolant puddle under vehicle after parking
6.2L V8 Higher Maintenance Costs (L9H Engine)
The 6.2L V8 (L9H engine code) in the 2013 Silverado shares many issues with the 5.3L, including AFM-related oil consumption and lifter problems. While it offers 403 horsepower, maintenance and repair costs are significantly higher due to the larger displacement and premium parts. Premium fuel is recommended for optimal performance. If planning long-term ownership of a 6.2L, consider AFM delete to prevent costly repairs.
Common Symptoms
- •Same AFM-related oil consumption as 5.3L
- •More expensive replacement parts
- •Higher fuel costs (premium recommended)
- •Spark plug replacement more expensive
- •Similar lifter failure rates to 5.3L

What engines came in the 2013 Chevy Silverado 1500?
The 2013 Silverado 1500 offered four engine options: a 4.3L V6 (195 hp), 4.8L V8 (302 hp), 5.3L V8 (315 hp), and 6.2L V8 (403 hp). The 5.3L was the most popular. There was also a 6.0L hybrid option rated at 332 hp. The 4.8L V8 is generally considered most reliable because it lacks the AFM system that causes oil consumption issues in the 5.3L and 6.2L.
Which 2013 Silverado engine is most reliable?
The 4.8L V8 (L20) is generally considered the most reliable 2013 Silverado engine because it does NOT have Active Fuel Management (AFM). Without AFM, the 4.8L avoids the oil consumption and lifter failure issues that plague the 5.3L and 6.2L engines. The 4.3L V6 is also reliable but underpowered for truck duties. If reliability is your priority, the 4.8L is the better choice over the 5.3L.
Why does my 2013 Silverado 5.3L use so much oil?
The 2013 Silverado 5.3L's excessive oil consumption is primarily caused by GM's defective low-tension piston rings combined with the Active Fuel Management (AFM) system. When AFM deactivates cylinders, oil spray intended for cylinder wall lubrication can enter the combustion chamber. The PCV system also draws oil vapor into the intake. GM's updated PCV valve cover can help but rarely solves the issue completely. Permanent solutions include AFM delete or engine rebuild with non-AFM components.
How much does it cost to replace a 2013 Silverado engine?
A remanufactured engine for a 2013 Silverado typically costs $2,500-$5,000 for the engine alone. With installation labor, total cost ranges from $4,000-$7,500 depending on engine size and shop rates. A complete engine rebuild runs $3,500-$6,000. We recommend getting a thorough diagnosis first - many issues like knock sensors, throttle body, or even lifters can be repaired for significantly less than full engine replacement. Call (707) 584-7727 for a personalized estimate.
What is AFM and why does it cause problems on the 2013 Silverado?
AFM (Active Fuel Management) is GM's cylinder deactivation system that shuts down 4 of the 8 cylinders during light-load driving to save fuel. The system uses special collapsing lifters that fail at alarming rates, causing engine noise and misfires. Additionally, the oil spray used during AFM operation contributes to excessive oil consumption. Many owners delete AFM during repairs to prevent recurrence.
What does "Reduced Engine Power" mean on my 2013 Silverado?
The "Reduced Engine Power" warning means your truck's computer detected a problem with the electronic throttle control system and has limited engine output for safety. Common causes include dirty or failed throttle body, faulty throttle position sensor (TPS), wiring issues (especially grounds), or accelerator pedal position sensor failure. Don't ignore this - continued driving in limp mode can cause additional problems. See our complete guide at /blog/reduced-engine-power-chevy-silverado-complete-guide
How often should I change oil in my 2013 Silverado?
For 5.3L and 6.2L engines with AFM, we recommend every 5,000 miles maximum (3,000-5,000 miles is better). More importantly, CHECK your oil level weekly. These engines can consume 1+ quart between changes, and running low accelerates wear. The 4.8L without AFM can safely follow the 7,500-mile interval with synthetic oil. Always use Dexos-approved 5W-30 synthetic oil.
Is the 2013 Silverado 5.3L or 6.2L better?
The 6.2L offers 88 more horsepower (403 vs 315 hp) but shares the same AFM-related issues as the 5.3L. The 6.2L has higher repair costs, requires premium fuel, and replacement parts are more expensive. For most owners, the 5.3L provides adequate power with lower operating costs. Choose the 6.2L only if you need maximum towing capacity or performance and accept higher maintenance expenses.
How many miles will a 2013 Silverado engine last?
With proper maintenance, the 4.8L can exceed 300,000 miles. The 5.3L and 6.2L typically last 150,000-250,000 miles, with AFM-related issues often appearing between 80,000-150,000 miles. Engine longevity depends heavily on oil change frequency, addressing problems early, and considering AFM delete. Many owners report excellent long-term reliability after performing AFM delete around 100,000 miles.
Should I buy a used 2013 Silverado with the 5.3L engine?
The 2013 Silverado 5.3L can be a good buy if you're aware of the AFM issues and plan accordingly. Before buying: check for oil consumption by looking for blue smoke, check oil level and condition, listen for ticking noises, and ask about oil change frequency. If the truck already has high miles (100,000+), consider having a mechanic inspect it and budget for potential AFM delete ($500-1,500) as a preventive measure.
What is the 2013 Silverado 5.3L engine code?
The 2013 Silverado 5.3L uses either the LC9 (VIN code "3") or LMG (VIN code "0") engine codes, both with VVT (Variable Valve Timing) and AFM (Active Fuel Management). The 8th digit of your VIN indicates the engine: "3" = LC9 FlexFuel, "0" = LMG FlexFuel, "J" = LY5 (without AFM, rare), "K" = L20 (4.8L). The 6.2L uses engine code L9H (VIN "2").
Can I disable AFM on my 2013 Silverado without a tune?
Yes, devices like the Range AFM Disabler plug into the OBD-II port and electronically prevent AFM from activating without requiring a tune. This prevents the constant cycling that causes lifter wear. However, if you already have lifter damage, you'll need mechanical repair. For a more permanent solution, a full AFM delete during engine work replaces the AFM lifters with standard lifters and requires a tune to delete the AFM programming.
