The 2009 Dodge Ram 1500 5.7 HEMI is one of the most popular full-size pickup trucks ever built, combining strong towing capability, V8 performance, and long-term durability. To keep the legendary 5.7L HEMI engine running properly, choosing the correct engine oil is extremely important.
The HEMI engine uses advanced systems like the Multi-Displacement System (MDS), which relies on proper oil pressure and viscosity for smooth operation. Using the wrong oil or delaying oil changes can contribute to lifter noise, oil pressure issues, and premature engine wear.
What Oil Does a 2009 Dodge Ram 1500 5.7 Take?
The recommended oil type for the 2009 Dodge Ram 1500 5.7 HEMI is SAE 5W-20 full synthetic motor oil that meets Chrysler MS-6395 specifications.
This viscosity is specifically recommended to maintain proper lubrication and support the HEMI engine’s Multi-Displacement System (MDS). Using heavier oil can sometimes affect oil flow and hydraulic lifter performance.
Best Overall Choice: Full synthetic SAE 5W-20 motor oil provides the best balance of cold-start protection, fuel economy, and HEMI engine lubrication.
2009 Dodge Ram 1500 5.7 Oil Capacity
The 5.7L HEMI V8 requires a relatively large oil capacity to maintain proper lubrication and cooling under towing and heavy-load conditions.
Important: Always replace the oil filter during every oil change and verify the oil level after filling. Running the HEMI engine low on oil may contribute to lifter and camshaft wear.
Best Oil for 5.7 HEMI Engine
Using premium synthetic oil is highly recommended for HEMI engines because they operate under high heat and load conditions, especially during towing or highway driving.
