What oil is recommended for a 5.7 Hemi?

The recommended oil for a 5.7 Hemi engine is a high-quality synthetic motor oil that meets the manufacturer's specifications. The 5.7 Hemi is a powerful V8 engine found in various Dodge and Chrysler vehicles, and using the right oil is crucial for its optimal performance and longevity.

Choosing the Right Oil for a 5.7 Hemi

When selecting an oil for a 5.7 Hemi engine, there are several factors to consider:

• Oil Viscosity: The recommended viscosity grade for a 5.7 Hemi engine is typically 5W-20 or 5W-30. These viscosity grades provide the necessary lubrication and protection for the engine's components, even in extreme temperatures.


• Oil Specification: The oil should meet the manufacturer's recommended specification, which is typically Chrysler MS-6395 or API SN/SM. These specifications ensure the oil is compatible with the engine's design and materials.


• Oil Type: A full synthetic motor oil is recommended for the 5.7 Hemi engine. Synthetic oils provide superior protection against wear, oxidation, and sludge buildup, which is especially important in high-performance engines like the 5.7 Hemi.

By using the recommended oil, you can help ensure your 5.7 Hemi engine runs smoothly, efficiently, and with maximum power output.

Oil Change Intervals for a 5.7 Hemi

The recommended oil change interval for a 5.7 Hemi engine is typically every 5,000 to 7,500 miles, or as specified by the vehicle manufacturer. It's important to follow the recommended oil change schedule to maintain the engine's performance and longevity.

Remember, always refer to your vehicle's owner's manual for the specific oil recommendations and change intervals, as they may vary depending on the make, model, and year of your vehicle.

What is the best oil for a 5.7 L Hemi?

The best oil for a 5.7L Hemi engine is SAE 5W-20 full synthetic or full synthetic blend, though some sources recommend 5W-30 for older engines to help with Hemi tick. It's crucial to use a full synthetic or high-quality synthetic blend that meets the Chrysler MS-6395 specification and is suitable for your specific year model. Always check your owner's manual for the exact recommendation.
 
Oil type and grade

• For most modern Hemi engines: Use SAE 5W-20 full synthetic oil. This is what the manufacturer typically specifies for optimal performance and fuel economy. 
• For older Hemi engines (high mileage): Some owners report better results with SAE 5W-30 full synthetic oil, especially if they are experiencing engine noise or valve train ticking. However, using a 5W-30 may affect fuel economy and is not the factory-recommended viscosity for newer models. 
• High-performance engines: Some high-performance versions, like those found in the Hellcat or Apache, may require a different oil, such as a 0W-40. Always check the manufacturer's recommendation for your specific engine. 

Oil quality and brand

• Use high-quality full synthetic: Full synthetic oils provide better lubrication and protection, especially at high temperatures. 
• Consider brands: Some popular and well-regarded brands include Pennzoil Ultra Platinum, Mobil1, Castrol, and Royal Purple. 
• Check specifications: Ensure the oil meets the Chrysler MS-6395 oil quality specification, which is important for many modern engines. 

Oil change and maintenance

• Follow the owner's manual: Your owner's manual is the most reliable source for your vehicle's specific requirements. 
• Change the filter: Always change the oil filter when you change the oil. 
• Frequency: Change the oil and filter every 5,000 miles, or more frequently if you are towing or driving in harsh conditions, to help extend engine life. 

In summary: The best oil is one that meets the manufacturer's recommended viscosity (typically 5W-20 for newer models) and quality specification (MS-6395). Using a high-quality full synthetic oil and changing it regularly will help protect your engine and prevent common issues like Hemi tick.

How to avoid hemi tick?

Avoid Long Idle Times
Extended idling can contribute to Hemi ticking sounds, especially if oil pressure drops during idle. If possible, avoid letting your engine idle for long periods to reduce the chance of ticking.

Can you run 5W30 in a 5.7 Hemi?

You should generally not use 5W-30 oil in a 5.7L Hemi unless specified in your owner's manual, as many modern Hemis are designed for 5W-20 or 0W-20 oil. Using a thicker oil can cause issues with the Multi-Displacement System (MDS) (also known as cylinder deactivation) and hydraulic lifters, potentially leading to lifter noise, hesitation, or improper valve operation. However, some older models or those not equipped with MDS may allow for 5W-30, especially for heavy-duty towing, so always check your specific vehicle's owner's manual for the manufacturer's recommendation. 
Reasons to avoid 5W-30

• MDS and lifter issues: The Multi-Displacement System (MDS) solenoids and hydraulic lifters are designed to work with a specific, thinner viscosity of oil (like 5W-20). A thicker oil can impede their proper operation. 
• Reduced fuel economy: Thicker oil has more resistance, which can slightly decrease fuel efficiency. 
• Potential for long-term damage: While a one-time use in an emergency might not cause lasting harm, consistently using the wrong oil can lead to premature wear over time. 

When 5W-30 might be used

• Older models: Some older Hemi engines, or those without the MDS system, may have been designed to use 5W-30.
• Heavy-duty towing: In certain applications, especially older 2500 models that did a lot of towing, 5W-30 was sometimes recommended. 

What to do instead

• Check the oil cap: The recommended oil viscosity is often printed directly on the oil filler cap of the engine. 
• Consult the owner's manual: Always refer to your specific owner's manual for the correct oil type and viscosity. This is the most reliable source of information for your engine. 

How many quarts of oil does a 5.7 L Hemi take?

The oil capacity for a 5.7L Hemi engine is typically 7 quarts, though this can vary slightly by model year and specific application. It is always best to consult your owner's manual for the most accurate capacity for your specific vehicle and to confirm the recommended oil viscosity, which is often 5W-20 but can be 0W-20 on newer models. After adding the oil, it's crucial to run the engine briefly and then check the dipstick to ensure the level is correct, as overfilling can cause damage.
 
Key details for a 5.7L Hemi oil change:

• Capacity: The most common capacity is 7 quarts for an oil and filter change. Some sources may list a slightly different amount, such as 6.9 quarts for certain RAM 1500 models. 
• Viscosity: The recommended oil weight is frequently 5W-20, but newer vehicles may specify 0W-20. Always check the owner's manual or the oil filler cap for the correct grade. 
• Procedure:
  • Add the specified amount of new oil, but do not overfill. 
  • Start the engine and let it run for about a minute to fill the new filter and circulate the oil. 
  • Turn the engine off and wait a few minutes for the oil to settle.
  • Check the dipstick and add more oil if needed to reach the "full" mark. 
• Important Note: Never overfill the engine with oil, as this can cause foaming and potentially damage engine components.
