RAM 3500
Data verified by Nick Marchenko, PhD
Maintaining the engine oil in your RAM 3500 is crucial for optimal performance and longevity. The 2012–2022 RAM 3500 offers four engine options, including the 5.7L HEMI EZC V-8 and the robust 6.7L Turbo Diesel. Depending on the engine, oil capacities range from 7 quarts for the petrol engines to 12 quarts for the diesel variant, with recommended viscosities of 5W-20, 5W-30, and 5W-40. Additionally, the coolant capacities vary, with the 5.7L HEMI requiring 18.3 to 18.7 quarts and the 6.7L Turbo Diesel needing 22.6 quarts.
Regular oil changes are essential to ensure the smooth operation of your RAM 3500, especially considering the heavy-duty demands placed on these engines. For the 5.7L HEMI engines, using the correct viscosity is vital, as using the wrong oil can lead to decreased performance or engine damage. Always refer to your owner's manual for specific maintenance intervals and recommendations.

The coolant capacity for the RAM 3500 varies by engine: 5.7L HEMI EZC: 18.3 qt; 5.7L HEMI EZC: 18.7 qt; 6.4L HEMI: 16.6 qt; 6.7L Turbo Diesel: 22.6 qt. Use the coolant specification listed in the owner's manual for your engine variant.
What type of oil does the RAM 3500 use?
The RAM 3500 uses different types of oil depending on the engine. The 5.7L HEMI engines typically use 5W-20 or 5W-30, while the 6.4L HEMI requires 0W-40, and the 6.7L Turbo Diesel uses 5W-40.
How many quarts of oil does the RAM 3500 take?
The oil capacity for the RAM 3500 varies by engine. The 5.7L HEMI engines require 7 quarts, while the 6.7L Turbo Diesel requires 12 quarts.
How often should I change oil in a RAM 3500?
It is generally recommended to change the oil in a RAM 3500 every 7,500 miles or every six months, whichever comes first. However, always refer to your owner's manual for specific recommendations based on your driving conditions.
What is the coolant capacity of the RAM 3500?
The coolant capacity for the RAM 3500 varies by engine. The 5.7L HEMI engines require between 18.3 and 18.7 quarts, while the 6.7L Turbo Diesel requires 22.6 quarts.
Does the RAM 3500 need synthetic oil?
While synthetic oil is not mandatory, it is highly recommended for the RAM 3500, especially for the 6.4L HEMI and 6.7L Turbo Diesel engines. Synthetic oil provides better protection and performance under extreme conditions.
What happens if I use the wrong oil viscosity in my RAM 3500?
Using the wrong oil viscosity can lead to inadequate lubrication, increased engine wear, and potential overheating. It's crucial to use the recommended viscosity for your specific engine.
What is an oil life monitor and how does it work?
An oil life monitor is a system that tracks the condition of your engine oil based on factors like mileage and driving conditions. It alerts you when it's time for an oil change, helping to maintain engine health.
Can I mix synthetic and conventional oil?
While it is technically possible to mix synthetic and conventional oil, it is not recommended. Mixing can reduce the effectiveness of the oil and may not provide optimal protection for your engine.
How do I know if my RAM 3500 has an oil leak?
Signs of an oil leak in your RAM 3500 include oil spots on the ground where you park, a burning oil smell, or a low oil level warning light on your dashboard. Regularly checking your oil level can also help identify leaks.
What causes excessive oil consumption?
Excessive oil consumption can be caused by worn engine components, such as piston rings or valve seals, which allow oil to escape into the combustion chamber. Regular maintenance and timely oil changes can help mitigate this issue.
Should I check my oil when the engine is hot or cold?
It's best to check your oil when the engine is warm, but not hot. This allows the oil to circulate and gives a more accurate reading on the dipstick.
What is the difference between an oil change and a flush?
An oil change involves draining the old oil and replacing it with new oil, while an oil flush is a more intensive process that cleans out the engine by removing sludge and contaminants. Flushing is typically not necessary for regular maintenance.
