What oil does a Ram 2500 6.7 diesel take?
The recommended oil for a Ram 2500 6.7 diesel engine is 15W-40 heavy-duty diesel engine oil. This oil specification is designed to meet the performance and protection requirements of modern high-output diesel engines like the one found in the Ram 2500 6.7 diesel.
Detailed Explanation
The Ram 2500 is a heavy-duty pickup truck powered by a 6.7-liter Cummins turbo-diesel engine. This robust engine requires a specific type of engine oil to ensure proper lubrication, wear protection, and optimal performance.
The recommended oil for the Ram 2500 6.7 diesel is a 15W-40 heavy-duty diesel engine oil. This oil viscosity and grade is specifically designed to meet the demands of modern high-output diesel engines, providing the necessary protection against wear, deposits, and sludge buildup.
The key reasons for using a 15W-40 oil in the Ram 2500 6.7 diesel are:
- Viscosity: The 15W-40 viscosity ensures the oil flows easily at low temperatures during startup, while also maintaining sufficient thickness at high operating temperatures to prevent excessive wear and oil consumption.
- Diesel Engine Formulation: Diesel engine oils are specifically blended with additives to provide enhanced detergency, dispersancy, and anti-wear properties required for the high-stress environment of a diesel engine.
- Heavy-Duty Performance: The "heavy-duty" designation indicates the oil meets the stringent performance requirements of modern high-output diesel engines, including the Cummins 6.7L in the Ram 2500.
It's important to always use the recommended 15W-40 heavy-duty diesel engine oil in the Ram 2500 6.7 diesel to ensure optimal engine protection, performance, and longevity.
How much oil does a 6.7 Ram 2500 take?
12 quarts
Capacity: 12 quarts (with filter). After filling, start the engine and idle for several minutes.
What is the best oil for a 6.7 diesel?
The ONLY SYNTHETIC oil specified by the workshop manual for the 6.7L Power Stroke engine is Motorcraft® SAE 5W-40 Full Synthetic Diesel Motor Oil. Motorcraft® SAE 10W-30 Super Duty Diesel Motor Oil is considered the standard oil to be used in this engine and is identified specifically on the engine oil fill cap.
Can I use 15W40 instead of 10w30?
In hot climates, where engines can reach high temperatures, 15W40 oil's superior high-temperature protection would be advantageous. Conversely, in cold climates, 10W-30 oil's improved cold-start performance would be beneficial.
How many gallons of oil does a 6.7 diesel take?
The 6.7 Powerstroke's oil capacity is 15 quarts if your Ford F-250 to F-600 was produced after 2022. Those from 2011 to 2022 should hold approximately 13 quarts. A Ford F-650 or an F-750 from 2015 to 2022 can hold up to 15 quarts, but 2023 models and later with a 6.7 Powerstroke have an oil capacity of 17 quarts.
Is 5W-40 better than 15W-40?
The “W” stands for “winter.” So, for example, a 5W-40 engine oil and a 15W-40 engine oil will have the same high-temperature flow characteristics (40), but the 5W- will flow better and faster at lower temperatures than the 15W-.
How often do you change oil on a 6.7 diesel?
every 10,000 miles
The 6.7 Powerstroke typically requires an oil change every 10,000 miles for models manufactured between 2011 and 2022. For those built in 2023 and later, the interval can extend up to 15,000 miles before service is necessary.
Can you run 15W40 in a 6.7 Cummins?
Folks…the oil cap says 10W-30 or 5W-40 for severe use on all 6.7 Powerstrokes, for a reason. If you look past the temperature chart in the owner's manual and read the words, you'll find that 15W-40 is only acceptable when running biofuel and is not a substitute for 5W-40 under severe conditions.
What kind of oil does a Dodge 2500 diesel take?
Oil Grade: SEO39
12 quarts (with filter).
Why did Cummins switch to 10W30?
The most common reason for the change is the increase in fuel economy by switching to lower viscosity oil. Fuel economy improvements are correlated with viscosity.
Can I use 15W40 instead of 10w30 in diesel engines?
Both 15W-40 and 10W-30 oils are multi-grade oils commonly used in diesel engines.
