The 2008 Dodge Charger generally uses SAE 5W-20 engine oil, but the exact specification depends on the engine installed in the car. Always verify with the owner’s manual or the under-hood oil fill cap for your specific vehicle.
Engine options and oil requirements
In 2008, the Charger was offered with several engines. Here are the typical oil specifications by engine family.
- 3.5L V6 (24-valve) – Use SAE 5W-20 synthetic or synthetic-blend oil. Fuel economy and emissions considerations favor the lighter grade. Capacity is typically around 5 quarts with a filter.
- 4.7L V8 – Use SAE 5W-30 synthetic or synthetic-blend oil. This engine generally holds roughly 5–6 quarts with a filter, depending on the exact configuration.
- 5.7L Hemi V8 – Use SAE 5W-20 synthetic oil. This larger V8 typically requires about 7 quarts with a filter.
- 6.1L Hemi (SRT8) – Use SAE 5W-20 synthetic oil. Capacity is around 7 quarts with a filter, reflecting the higher performance engine.
Guidance: while 5W-20 is common across these engines, hot climates or severe service can lead to exceptions. Always confirm with the owner’s manual or the engine’s oil fill cap, and use oil that meets API service standards and ILSAC specification for your region.
Choosing the right oil and maintenance intervals
To ensure compatibility and engine longevity, follow these standard practices when selecting oil and planning changes.
- Consult the owner’s manual for the exact oil grade and capacity for your specific engine and model year.
- Use SAE 5W-20 oil that meets API SN (or newer) and ILSAC GF-5 specifications; synthetic or synthetic-blend formulations are acceptable.
- Consider synthetic oil if you drive in extreme temperatures, tow frequently, or prefer longer intervals between changes.
- Follow recommended oil-change intervals from the manual, typically ranging from 3,000–5,000 miles for conventional oil and up to 7,500–10,000 miles for synthetic in many driving conditions.
By sticking to the manufacturer’s guidance and using the correct oil grade, you help protect the engine’s longevity and performance across the Charger’s available configurations.
How to verify the right oil for your car
If you’re unsure which engine your 2008 Charger has or want to be sure you’re using the correct oil, use these quick checks.
- Check the under-hood oil-fill cap for the recommended viscosity printed on it.
- Review the owner’s manual or the vehicle information sticker located in the door jamb or fuel filler area for the exact grade.
- Match the oil to API SN or newer and ILSAC GF-5 specifications as a baseline.
- Use a synthetic or synthetic-blend oil if you expect extended intervals or operate in challenging conditions.
Correct oil choice supports optimal performance, fuel efficiency, and engine protection for the 2008 Charger family.
Summary
For most 2008 Dodge Chargers, SAE 5W-20 is the standard recommendation, with engine-dependent variations. The 3.5L V6 and 5.7L Hemi commonly use 5W-20, while the 4.7L V8 may use 5W-30 in some setups. Always verify your exact engine and follow the owner’s manual or the fill-cap label. Use oil that meets current API and ILSAC standards, and choose synthetic or synthetic-blend as appropriate for your climate and driving needs. Regular maintenance and using the correct grade will help keep your Charger running smoothly.
What oil do I need for a 2008 Dodge Charger?
Synthetic blend 5W-20 engine oil that provides durable wear protection and reduces engine wear.
Can I use 5W-30 instead of 5W20 in my Dodge?
Using 5W-30 instead can reduce fuel economy and impede flow throughout the engine. While using it temporarily in a pinch likely won't cause your engine lasting harm, remember that the engineers who built your engine did so with a specific viscosity oil in mind, meaning it's best to stick with it.
Which oil is better, 5W-30 or 10w40?
In other words, a lubricant with SAE 5W-30 will behave better when cold than a lubricant with SAE 10W-40. In contrast, oils with a higher SAE after the W generate thicker films of lubricant and better protect the mechanical parts when the vehicle is already hot.
What kind of oil does a 2008 Dodge Charger 5.7 Hemi take?
SAE 5W-20 oil
5W-20 (All TEMPS) - Vehicles with the 5.7L Multiple Displacement System (MDS) must use SAE 5W-20 oil.
