Use 5W-20 motor oil that meets API SN/ILSAC GF-5 and Mopar MS-6395 specifications. Both full synthetic and synthetic-blend formulations are acceptable for the 2.4 L Tigershark engine in the 2015 Dodge Dart.
Oil grade and specifications
The 2015 Dodge Dart with a 2.4-liter engine requires a viscosity of 5W-20 and must meet the Mopar MS-6395 specification, along with API SN and ILSAC GF-5 standards. This combination protects the engine’s moving parts and supports the engine’s variable timing system. While you’ll often see 5W-20 offered as a full synthetic or a synthetic-blend, both options that meet MS-6395 are generally acceptable.
What follows outlines the oils that meet the factory spec and are commonly used by Dart owners. Choosing an oil that adheres to the MS-6395 standard ensures compatibility with the engine’s design and warranty considerations.
- 5W-20 full synthetic motor oil that meets API SN/ILSAC GF-5 and Mopar MS-6395
- 5W-20 synthetic-blend motor oil that meets API SN/ILSAC GF-5 and Mopar MS-6395
Either option—full synthetic or synthetic-blend—provides reliable lubrication for daily driving and performance. Avoid using heavier viscosities like 5W-30 or 0W-30 unless specifically advised by an automotive professional for unusual climate or usage conditions.
Oil change intervals and maintenance guidance
Oil-change frequency depends on oil type, driving conditions, and the vehicle’s oil life monitoring system. The following guidance reflects common practice for the 2.4 L Tigershark engine in the Dart, but consult your owner’s manual or dealer for exact intervals.
- Normal driving with synthetic 5W-20: about 7,500 miles (or up to 12 months), whichever comes first, as indicated by the vehicle’s oil life monitor.
- Severe driving conditions or conventional oil: about 3,000–5,000 miles (or 3–6 months), depending on usage such as frequent short trips, extreme temperatures, dusty conditions, or towing.
Always rely on the car’s Oil Life Monitoring System (OLMS) for the most precise interval, and refer to the owner’s manual for any model-year-specific notes. If you’re unsure, a quick check with a Dodge service center can confirm the best schedule for your climate and driving habits.
Practical tips for maintaining 5W-20 oil health
Keep oil clean and at the proper level between changes. Use a quality filter, check the dipstick regularly, and monitor for signs of oil consumption or leaks. If you notice unusual exhaust smoke, engine knocking, or dashboard warnings, have the oil system inspected promptly.
Why the right oil matters for the 2.4 L Tigershark
The Tigershark 2.4 L engine uses advanced timing and lubrication requirements to balance performance and efficiency. Using the recommended 5W-20 oil that meets MS-6395 helps protect hydraulic tappets, maintain fuel economy, and support smooth operation of the variable Cam timing system. Opting for the wrong viscosity or an oil that doesn’t meet the required spec can lead to reduced lubrication efficiency and potential warranty concerns.
What to check if you’re due for an oil change
Before you head to the service bay, verify the following:
- Oil viscosity: 5W-20
- Oil specification: API SN, ILSAC GF-5
- Manufacturer specification: Mopar MS-6395
- Oil type: full synthetic or synthetic-blend (both acceptable if they meet the spec)
Following the recommended oil type and change intervals helps preserve engine performance, efficiency, and warranty coverage for the 2015 Dodge Dart’s 2.4 L engine.
Summary
For a 2015 Dodge Dart with a 2.4 L Tigershark engine, the recommended oil is 5W-20 that meets API SN/ILSAC GF-5 and Mopar MS-6395. You can choose a full synthetic or a synthetic-blend as long as it complies with these standards. Adhere to the vehicle’s Oil Life Monitor and the owner’s manual to determine exact change intervals, typically around 7,500 miles for normal synthetic use or 3,000–5,000 miles under severe conditions. Regular checks of oil level and quality help maintain engine health and performance.
