In 2011, the Dodge Challenger came in five different models with three engine options: a 3.6L V6, a 5.7L V8, and a 6.4L V8. Each engine requires specific oil type and capacity. The smallest engine needs 6 quarts of SAE 5W-30 synthetic motor oil, while the 5.7L engine requires 7 quarts of SAE 0W-40. You can use SAE 5W-40 as an alternative, but it's not recommended for extended periods. Understanding oil weights is essential, as the first number indicates viscosity during startup and the second represents viscosity at operating temperature. Lower numbers are generally preferable for efficient engine performance, contributing to longevity and cost savings in the long term.
To ensure top performance and maximum protection in all operating conditions, Dodge suggests using only API Certified engine oils that adhere to the Chrysler Material Standard MS-6395. For the 2011 Dodge Challenger with a 3.6L engine, it is advised to use SAE 5W-30 oil, while the 5.7L engine should use SAE 5W-20 oil. The oil capacity for the 3.6L engine is 6 US quarts (5.6 liters), and for the 5.7L engine, it is 7 US quarts (6.6 liters).
