Keeping your 2019 Ram 2500 diesel in top shape starts with choosing the right oil filter. This simple but essential component ensures that your 6.7L Cummins engine stays clean, protected, and performing at its best. In the USA, where Ram 2500 trucks are widely used for towing, heavy-duty hauling, and long-distance drives, the quality of your oil filter can make a big difference in overall engine life and performance.
Let’s explore how to pick the best oil filter for 2019 Ram 2500 diesel trucks — and why it matters.
What Does an Oil Filter Do in a 2019 Ram 2500 Diesel?
An oil filter removes dirt, carbon particles, and metal shavings from the engine oil. Over time, engine oil collects contaminants from combustion and wear. If these impurities aren’t filtered out, they can cause internal damage, clog oil passages, and reduce lubrication efficiency.
For a 2019 Ram 2500 diesel with a 6.7 Cummins engine, the oil filter ensures clean oil flows through critical components — like pistons, bearings, and the turbocharger — keeping the engine cool and reducing wear.
Why Is Choosing the Right Oil Filter Important?
Choosing the right oil filter isn’t just about fit; it’s about protection. In the USA, many Ram 2500 trucks face extreme operating conditions — from the hot deserts of Arizona to the cold highways of Minnesota. A poor-quality filter may not hold up to these environments.
A premium oil filter for 2019 Ram 2500 diesel offers:
Better filtration efficiency (traps smaller contaminants).
Longer oil changes intervals without clogging.
Improved oil flow, ensuring constant lubrication.
Durability against high pressure and temperature.
The right filter keeps your Cummins engine running cleaner, longer, and more efficiently.
OEM vs. Aftermarket Oil Filters — Which Is Better?
When it comes to Ram 2500 oil filters, you’ll find two main options: OEM (Original Equipment Manufacturer) and aftermarket.
OEM Filters:
OEM options, like the Mopar oil filter, are designed to meet Cummins factory specifications. They offer exact fitment, tested materials, and proven reliability. OEM filters are ideal for USA truck owners who prioritize factory performance and warranty compliance.Aftermarket Filters:
High-quality aftermarket brands like Fleetguard or WIX can provide excellent performance, often at a lower cost. However, it’s important to choose reputable brands. Some cheap alternatives might not filter efficiently or fit correctly, risking engine damage.
Expert Tip: For the best results, stick to OEM or trusted aftermarket brands that clearly specify “for 2019 Ram 2500 6.7L Cummins diesel.”
How Often Should You Replace the Oil Filter?
Regular replacement is key to maintaining your diesel engine’s health. For most USA drivers, experts recommend changing your oil filter every 7,500 to 10,000 miles, or with each oil change.
However, if you use your truck for:
Towing heavy loads
Long highway drives
Driving in dusty or hot environments
…it’s wise to replace it more frequently, around every 5,000 miles. A clean oil filter ensures your 6.7 Cummins performs efficiently, even under tough American conditions.
How to Choose the Best Oil Filter for Your 2019 Ram 2500 Diesel
When selecting the best oil filter, consider these essential factors:
Compatibility: Always verify that the filter fits your 2019 Ram 2500 diesel engine.
Filter Media: Look for high-efficiency synthetic or cellulose blends for better filtration.
Micron Rating: A lower micron rating (10–20 microns) means finer filtration.
Build Quality: Choose filters with durable steel casings and strong bypass valves.
Brand Reputation: Opt for trusted names like Mopar, Fleetguard, or WIX for proven reliability.
Buying from authorized USA retailers or Mopar parts dealers ensures you get a genuine, high-quality product that meets Cummins standards.
Where Can You Buy Reliable Oil Filters in the USA?
You can find genuine Mopar oil filters and other trusted brands at:
Authorized Mopar dealerships
Major retailers like AutoZone, NAPA, and O’Reilly Auto Parts
Reputable online stores specializing in diesel filters
Before purchasing, always confirm the part number matches your 2019 Ram 2500 diesel specifications. Avoid cheap, unverified sellers offering “universal” filters — they can cause serious damage to your engine.
Can You Replace the Oil Filter Yourself?
Yes! Many Ram owners across the USA prefer to do it themselves. Replacing the oil filter is a quick and simple task if you have basic tools.
Here’s how:
Warm up the engine, then turn it off.
Drain the old engine oil.
Remove the old oil filter.
Apply a thin layer of new oil to the new filter’s gasket.
Install the new oil filter and tighten it by hand.
Refill with the recommended oil type and check for leaks.
This DIY maintenance step can save you money and keep your diesel engine running strong between professional services.
