EPA Fuel Economy: 18 MPG Combined

The 2023 RAM 1500 5.7L V8 Crew Cab delivers an EPA-estimated combined fuel economy of 18 MPG, making it a respectable choice among full-size pickup trucks equipped with a V8 engine. With 15 MPG in city driving and 22 MPG on the highway, this truck balances the power and towing capacity that RAM 1500 owners demand with reasonable fuel efficiency for a vehicle in its class. The 5.7L V8 engine produces 383 horsepower and 400 lb-ft of torque, providing the capability to handle serious hauling and towing tasks while maintaining moderate fuel consumption for a truck of this size and capability.

As a full-size crew cab pickup, the 2023 RAM 1500 is designed primarily for work and heavy-duty applications rather than fuel economy optimization. The 18 MPG combined rating reflects the trade-offs inherent in choosing a V8-powered pickup truck: you gain considerable power and towing capacity at the cost of fuel efficiency compared to smaller vehicles. The 8-speed automatic transmission helps maximize efficiency by keeping the V8 engine operating in its optimal RPM range across various driving conditions. For buyers who prioritize capability and performance, the 18 MPG rating represents a practical balance for a truck in this segment.

City vs Highway Performance

The 2023 RAM 1500 5.7L V8 shows a significant difference between its city and highway fuel economy ratings, which is typical for V8-powered trucks. The 15 MPG city rating reflects the challenges of urban driving with frequent acceleration, deceleration, and idle time. Stop-and-go traffic forces the 5.7L V8 to work harder and less efficiently than on open roads. The 22 MPG highway rating demonstrates the engine’s stronger efficiency when cruising at consistent speeds on interstates and longer stretches of road. This 7 MPG difference between city and highway driving is common for large trucks with V8 engines, as highway driving allows the transmission to shift into higher gears where the engine operates more efficiently.

Understanding this split is important for potential buyers who need to estimate their actual fuel costs. If your driving consists primarily of highway miles, you’ll see better fuel economy closer to the 22 MPG rating. Conversely, if you spend most time in urban and suburban environments with frequent stop-and-go traffic, expect fuel economy closer to the 15 MPG city figure. Most drivers will experience results near the 18 MPG combined average, which represents a blend of approximately 55% city driving and 45% highway driving based on EPA test procedures.

Annual Fuel Cost

Based on 15,000 miles driven annually at the EPA combined rating of 18 MPG with gasoline priced at $3.50 per gallon, here’s the fuel cost calculation:

Annual Fuel Cost Math:
15,000 miles ÷ 18 MPG = 833.33 gallons per year
833.33 gallons × $3.50 per gallon = $2,916.67 per year

This translates to approximately $243 monthly in fuel costs under average driving conditions. Keep in mind that actual fuel costs will vary based on gas prices in your area, which fluctuate regularly. Drivers who exceed 15,000 miles annually or primarily drive in city conditions will see higher fuel expenses, while those with mostly highway miles may spend slightly less. Over a five-year ownership period, you should budget roughly $14,583 for fuel at current prices and typical mileage levels.

Real-World MPG Expectations

Real-world fuel economy for the 2023 RAM 1500 5.7L V8 Crew Cab typically aligns fairly closely with EPA ratings, though individual results vary based on driving habits and conditions. Many owners report combined fuel economy between 17-19 MPG under normal driving conditions. Aggressive acceleration, excessive idling, and towing will reduce efficiency, potentially dropping combined economy to 15-16 MPG. Conversely, smooth acceleration, highway cruising, and lighter loading can push efficiency toward 20 MPG or slightly better.

To maximize fuel economy with the 5.7L V8, maintain proper tire pressure, avoid unnecessary cargo weight, use cruise control on highways, and reduce aggressive driving behaviors. Engine maintenance, including regular oil changes and air filter replacements, also helps maintain optimal efficiency. Cold weather driving typically reduces MPG by 10-15% compared to warm weather conditions.

How It Compares

The 2023 RAM 1500 5.7L V8’s 18 MPG combined rating is competitive within the full-size V8 pickup truck segment. The 2023 Chevrolet Silverado 1500 with a 5.3L V8 achieves approximately 17 MPG combined, while the 2023 Ford F-150 with a 5.0L V8 achieves roughly 18 MPG combined. Trucks equipped with smaller displacement V8s or turbocharged engines may achieve slightly better efficiency, while larger V8 options typically deliver fewer miles per gallon. RAM’s 5.7L V8 performs admirably in this comparison, offering strong power output without sacrificing fuel economy relative to competitors.

Tips to Maximize Efficiency

• Maintain recommended tire pressure—underinflated tires increase rolling resistance and reduce MPG
• Minimize unnecessary weight and cargo—every 100 pounds of extra weight reduces fuel economy by approximately 1-2%
• Use cruise control on highways—maintaining steady speeds improves efficiency significantly
• Avoid rapid acceleration—smooth, gradual acceleration keeps the V8 operating efficiently
• Plan routes to minimize idling and stop-and-go traffic when possible

Frequently Asked Questions

What is the fuel tank capacity of the 2023 RAM 1500?
The 2023 RAM 1500 has a fuel tank capacity of approximately 26 gallons, allowing a driving range of around 468 miles on a full tank at the combined 18 MPG rating.

Does the 5.7L V8 require premium gasoline?
No, the 2023 RAM 1500 5.7L V8 is designed to run on regular unleaded gasoline with an 87 octane rating, helping keep fuel costs manageable.

How does towing affect fuel economy?
Towing significantly reduces fuel economy, typically decreasing MPG by 20-30% depending on trailer weight and aerodynamics. Expect combined economy closer to 13-14 MPG when actively towing.

The 2023 RAM 1500 5.7L V8 Crew Cab offers capable V8 performance with reasonable fuel economy for its class. At 18 MPG combined, this truck provides a practical balance for buyers seeking power, towing capacity, and dependable efficiency for work and everyday driving.
