Best Oil For Chrysler 300: Compare 10 Synthetic Oils

#1 · Best Overall

1. Mopar 0W-40 Full Synthetic

• Compatible with Vehicle Type: Car
• Size: 7 quarts
• Container Type: Bottle

Best for: Mopar 0W-40 applications.

Why it ranks #1: Its title names Chrysler and specifies full synthetic 0W-40; the seven-quart supply suits buyers whose engine requires this grade.

The Mopar-branded 0W-40 specification is the clearest differentiator of this seven-quart Pennzoil Ultra Platinum package. It offers a Chrysler, Dodge, and Jeep-focused oil choice in a multi-quart quantity, making it relevant to Chrysler 300 owners whose vehicle calls for this exact viscosity and who need more than a single quart.

This listing identifies the oil as full synthetic 0W-40 and names Chrysler, Dodge, and Jeep in its title, making the grade and brand context its central selection cues. The seven-quart quantity supplies more oil than the one-quart Pennzoil Ultra Platinum option, which can suit a larger service requirement or leave oil available for replenishment. The listing provides no additional performance claims, so buyers should base the decision on the specified viscosity and vehicle requirements.

Skip it if you need another viscosity; Castrol EDGE 5W-30 explicitly meets Chrysler MS 6395 engine test requirements.

This Mopar-labeled 0W-40 package suits Chrysler 300 owners whose service requirements call for that grade and who can use seven quarts. It is not a general substitute for other specified viscosities, so grade remains the deciding boundary.

#2 · Best 5W-30 Option

2. Castrol EDGE 5W-30

• Compatible with Vehicle Type: Car, Truck
• Size: 5 Quarts
• Container Type: Jug

Best for: Chrysler MS 6395 5W-30.

Why it ranks #2: The 5W-30 listing states it meets Chrysler MS 6395 engine test requirements and provides five quarts of full synthetic oil.

Meeting Chrysler MS 6395 engine test requirements gives Castrol EDGE 5W-30 a concrete Chrysler-focused credential. The full-synthetic oil also claims stronger viscosity-breakdown resistance and high-stress performance, connecting its formulation to demanding operating conditions. Its five-quart jug is a practical quantity for owners whose Chrysler 300 calls for 5W-30.

Castrol claims three times stronger viscosity-breakdown performance than the leading full synthetic in its cited test and ten times better high-stress performance under high load and torque. Those claims speak to oil stability and demanding operation, while the stated Chrysler MS 6395 engine-test requirement offers a specific compatibility reference. The five-quart jug provides a single container for routine servicing. Its listed 20,000-mile oil-change interval is conditional on the vehicle’s requirements and one year, whichever comes first.

Skip it if you need 0W-20; Castrol EDGE 0W-20 also meets Chrysler MS 6395 engine test requirements.

This Castrol EDGE suits Chrysler 300 owners whose required grade is 5W-30 and who value a stated Chrysler MS 6395 reference. Consider its interval claim only within the stated one-year limit and the vehicle’s service requirements.

#3 · Best 0W-20 Option

3. Castrol EDGE 0W-20

• Compatible with Vehicle Type: Car, Hybrids, Truck
• Size: 5 Quarts
• Container Type: Jug

Best for: Chrysler-approved 0W-20.

Why it ranks #3: This five-quart full synthetic 0W-20 states it meets Chrysler MS 6395 engine test requirements, for vehicles calling for that viscosity.

Castrol EDGE 0W-20 meets Chrysler MS 6395 engine test requirements, providing a specific Chrysler-related reference for owners whose vehicle calls for this grade. Its full-synthetic formula also claims enhanced viscosity-breakdown resistance and high-stress performance, pairing that documentation with stated protection under demanding conditions.

Castrol claims three times stronger viscosity-breakdown performance than the leading full synthetic in its cited test and ten times better performance under high stress. These claims address oil stability and demanding operation, while the Chrysler MS 6395 engine-test requirement is a practical selection reference. The five-quart jug provides a single container for servicing. Its listed 20,000-mile change interval is subject to a one-year limit, whichever comes first, and the required 0W-20 grade remains decisive.

Skip it if you need a high-mileage-specific formula; Castrol EDGE High Mileage 0W-20 targets vehicles with over 75,000 miles.

This Castrol EDGE is a relevant option for Chrysler 300 owners whose vehicle specifies 0W-20 and who want a stated MS 6395 engine-test reference. Its interval claim remains subject to the one-year limit and vehicle requirements.

#4 · Best Single Quart

4. Pennzoil Ultra Platinum 0W-40

• Compatible with Vehicle Type: Car
• Size: 1 Quart
• Container Type: Bottle

Best for: Performance-focused 0W-40 quart.

Why it ranks #4: The 0W-40 full synthetic is described for high-performance engines and extreme temperatures, though its one-quart size is less convenient for a full fill.

Extreme-temperature performance and a high-performance-engine focus distinguish Pennzoil Ultra Platinum 0W-40. The full synthetic is also made with natural gas and comes in a one-quart bottle, suiting owners who need a small quantity for replenishment or whose service calls for this specific grade.

Pennzoil describes this oil as offering performance in extreme temperatures and protection against engine power loss, linking its 0W-40 formulation to high-performance use. The natural-gas manufacturing process is another stated differentiator. A one-quart bottle can be convenient when only a small amount is needed, but it supplies less oil than a full service may require. Its Chrysler 300 fit depends on the engine calling for 0W-40; the listing does not state Chrysler MS 6395.

Skip it if you need a five-quart 0W-40 supply; the Mopar Chrysler Dodge Jeep Pennzoil Ultra Platinum listing provides seven quarts.

Choose this Pennzoil when a Chrysler 300 calls for 0W-40 and a single quart suits the task, such as replenishment. Its high-performance and temperature claims are relevant, but its small quantity may not cover a full service.

The product meets Chrysler MS 6395 engine test requirements and comes in a five-quart container. Its 15,000-mile oil-change claim is limited by the stated one-year maximum, and the 5W-20 grade remains an essential fit consideration.

Skip it if you need 0W-20; Castrol EDGE High Mileage 0W-20 offers a high-mileage formulation in that grade.

For a higher-mileage Chrysler 300 requiring 5W-20, this Castrol combines leak and deposit control with an emission-system-focused technology. Its high-mileage formulation and Chrysler MS 6395 reference do not make it suitable for a different required viscosity.

Skip it if you need 5W-20; Castrol EDGE High Mileage 5W-20 is another high-mileage formulation with a Chrysler MS 6395 reference.

7. Valvoline Advanced 5W-30

• Compatible with Vehicle Type: Car, Truck
• Size: 5 QT
• Container Type: Jug

Best for: Everyday heat and deposit defense.

Why it ranks #7: The five-quart full synthetic 5W-30 offers wear, deposit, and heat protection, but its listing does not state a Chrysler-specific requirement.

Up to 2.5 times better heat protection than industry standards distinguishes Valvoline Advanced 5W-30. That claim targets thermal breakdown and sludge formation, while its deposit and wear defenses address everyday engine stress. For a Chrysler 300 requiring 5W-30, this full-synthetic five-quart jug brings several protection claims together.

Valvoline claims 40% stronger wear protection and 15% better deposit defense than industry standards; those features target friction and buildup that can affect engine cleanliness. Its up-to-2.5-times heat-protection claim addresses thermal breakdown and sludge formation, a practical consideration for driving that includes stop-and-go traffic or idling. The five-quart jug gives owners a single container for an oil service. The 5W-30 grade is the important fit boundary for a Chrysler 300.

Skip it if you need a different viscosity; Castrol EDGE 0W-20 meets Chrysler MS 6395 engine test requirements for that grade.

For a Chrysler 300 requiring 5W-30, this Valvoline option suits drivers seeking stated defenses against wear, deposits, and heat in a five-quart jug. Its protection claims do not override the vehicle’s required viscosity.

8. Mobil 1 Advanced 5W-30

• Compatible with Vehicle Type: Car
• Size: 5 Quart (Pack of 1)
• Container Type: Bottle

Best for: Severe-condition 5W-30 use.

Why it ranks #8: This five-quart 5W-30 full synthetic is listed for cars and severe conditions, but no Chrysler-specific approval appears in the supplied details.

Mobil 1 states that this 5W-30 full synthetic helps extend engine life even in severe conditions. Its additives help fight sludge, connecting its protection focus to a familiar maintenance concern. The five-quart bottle suits Chrysler 300 owners seeking this grade, provided it matches their engine’s specified viscosity.

The severe-condition engine-life claim makes this Mobil 1 option relevant to demanding operation, while the listed sludge-fighting additives target buildup inside the engine. Its 15,000-mile protection statement gives owners a stated coverage interval, though the product information does not provide a Chrysler-specific approval. A five-quart bottle supplies a substantial single-container quantity for servicing. Buyers should treat 5W-30 as the decisive fit requirement rather than assume the product suits every Chrysler 300 engine.

Skip it if you want an explicit Chrysler MS 6395 reference; Castrol EDGE 5W-30 lists that engine-test requirement.

This Mobil 1 suits Chrysler 300 owners seeking a 5W-30 oil with stated severe-condition and sludge-fighting benefits. The listing does not give a Chrysler-specific engine-test reference, so prioritize your vehicle’s required grade and approvals.

#9

9. Valvoline MaxLife 5W-20

• Compatible with Vehicle Type: Car, Truck
• Size: 5 qt (Pack of 1)
• Container Type: Bottle

Best for: High-mileage engine care.

Why it ranks #9: Its 5W-20 high-mileage formula targets vehicles with 75,000 miles or more, but the listing provides no Chrysler-specific requirement.

Seal conditioners are the key differentiator in Valvoline MaxLife 5W-20: they help address leaks and oil consumption in vehicles with 75,000 miles or more. Its full-synthetic formula also targets wear and sludge, giving high-mileage Chrysler 300 owners a focused option when this viscosity matches their vehicle’s requirements.

The seal conditioners are intended to help prevent oil leaks and reduce oil consumption, addressing two concerns identified for aging engines. Valvoline also states 50% stronger wear protection and 20% stronger sludge defense than industry standards, which supports its emphasis on engine protection as mileage accumulates. The five-quart bottle provides a single container for an oil change or replenishment. Its 5W-20 grade and high-mileage focus make the vehicle’s specified viscosity and mileage relevant selection boundaries.

Skip it if you need a different viscosity; Castrol EDGE High Mileage 0W-20 is another high-mileage option only if that grade matches your vehicle.

For Chrysler 300 owners past 75,000 miles who want seal-conditioner support alongside full-synthetic wear and sludge protection, MaxLife merits consideration. Its 5W-20 grade remains the key boundary: choose it only when that viscosity suits your engine.

• Container Type: Bottle

Best for: Specified 0W-16 hybrid use.

Why it ranks #10: This 0W-16 is listed for fuel economy and hybrid vehicles, but no Chrysler-specific fit is stated, so verify carefully before considering it.

Hybrid suitability is an explicit feature of Mobil 1 Advanced Fuel Economy 0W-16, setting it apart for owners whose vehicle calls for this unusually specific listed grade. The oil also targets engine efficiency and gas mileage, with sludge-fighting additives and a stated 15,000-mile protection claim.

Mobil says this full-synthetic oil helps increase engine efficiency and improve gas mileage, benefits linked to its Advanced Fuel Economy positioning. Its stated suitability for hybrid vehicles broadens the named use case, while additives help fight sludge as part of engine protection. The five-quart container provides a single supply for servicing. A Chrysler 300 owner should select it only when 0W-16 is the required viscosity; the listing does not provide a Chrysler-specific approval.

Skip it if you need Chrysler MS 6395 documentation; Castrol EDGE 0W-20 lists that engine-test requirement, but only for vehicles specifying 0W-20.

This Mobil 1 is for Chrysler 300 owners whose vehicle specifically calls for 0W-16, particularly where hybrid suitability and fuel-economy benefits matter. Its stated grade is a strict boundary, not a universal Chrysler 300 recommendation.
