If you’re driving a 2019 RAM 4500, you already know it’s built to tackle the toughest jobs. But is your engine oil doing its part to keep up with that workload? Let’s talk about what makes synthetic oil a smart choice and why it might be exactly what your RAM 4500 needs to keep running strong.
A Peek Under the Hood: What Powers Your RAM 4500?
The 2019 RAM 4500 packs some serious muscle. Standard models come equipped with a 6.4-liter HEMI V8 engine, delivering 410 horsepower and 429 lb.-ft. of torque. This setup ensures solid performance whether you’re on the highway or hauling heavy loads.
Opted for the Cummins 6.7-liter inline-six turbo diesel engine? Then you’re riding with 360 horsepower and a massive 800 lb.-ft. of torque. This option is all about raw pulling power, paired with a six-speed automatic transmission for smooth operation. Whether you stick with the HEMI or the Cummins, your truck is built to perform, but it depends on the right oil to operate at its best.
RAM 4500 Oil Type and Capacity
For the RAM 4500 with the 6.4L HEMI V8, you’ll want to use 0W-40 motor oil. It takes about 7 quarts, including what the filter holds. Look for oil with certifications like API SP or SN PLUS, along with Chrysler MS-A0921, MS-12633, and similar standards. These ensure the oil meets or exceeds the manufacturer’s requirements to protect your engine.
If you’re rolling with the Cummins 6.7L Diesel Turbo, go for 5W-40 diesel engine oil. This engine has a larger appetite, requiring around 12 quarts to handle the job, filter included. Make sure the oil meets heavy-duty standards, so it supports your engine’s durability even in tough conditions.
Why Choosing the Right Viscosity Matters
The viscosity rating—those numbers like 0W-40 or 5W-40—affects how well the oil flows, especially in extreme temperatures. Stick to the recommended oil type to ensure your RAM 4500 performs efficiently and stays protected, whether you’re starting up on a cold morning or climbing steep grades in hot weather.
Synthetic Oil vs. Conventional Oil
When it comes to keeping your engine healthy, you’ve got two main choices: synthetic and conventional oil.
What’s the Difference?
Synthetic motor oil is engineered in a lab for consistent, pure molecules. This makes it more reliable under stress. Its structure reduces friction, enhances fuel economy, and maintains stability under extreme heat or cold. Simply put, it’s designed to perform better and last longer.
Conventional oil, on the other hand, is refined from crude oil. Even after processing, it still contains impurities like sulfur and metals. These can lead to inconsistent performance and faster wear on your engine. While it’s cheaper upfront, conventional oil doesn’t offer the same long-lasting protection or efficiency as synthetic options.
What’s Best for Your RAM 4500?
Given the performance demands of a truck like the 2019 RAM 4500, synthetic oil is typically the smarter pick. It keeps up with the engine’s needs better and could save you money in the long run by reducing wear and tear.
Top Synthetic Oil Options for the RAM 4500
If you’re ready to go synthetic, here are some strong contenders:
- Shell Rotella T6 5W-40 Full Synthetic Diesel Oil
Perfect for the 6.7L Cummins diesel, Shell Rotella T6 offers excellent protection for heavy-duty engines. It’s designed to prevent wear, control deposits, and improve fuel economy, helping you get the most out of every gallon while going easier on your engine. - AMSOIL Signature Series 0W-40 100% Synthetic Motor Oil
If you’re driving the 6.4L HEMI, AMSOIL is an excellent choice. Its advanced formulation exceeds industry requirements, ensuring better performance under extreme heat and cold. It’s engineered to last, which means fewer oil changes and better overall engine protection.
Both options are solid investments for keeping your truck in peak condition and minimizing downtime.
FAQs
How often should I change the oil in my 2019 RAM 4500?
For the 6.4L HEMI using synthetic oil, change intervals typically fall around 6,000-8,000 miles, depending on driving conditions. For the 6.7L Cummins diesel, it’s best to follow manufacturer recommendations, often around 10,000 miles with high-quality oil. Check your owner’s manual for specifics.
Can I mix synthetic and conventional oil during an oil change?
Technically, yes, but it’s not recommended. Mixing oils can dilute the benefits of synthetic oil, reducing its effectiveness. Stick with one type for consistent performance.
Does using synthetic oil void my warranty?
No. As long as the oil you’re using meets the required specifications spelled out in your owner’s manual, your warranty stays intact.
Why does the Cummins engine need so much oil?
The larger oil capacity supports the unique demands of a heavy-duty diesel engine. It ensures consistent lubrication and efficient cooling, especially under heavy loads or prolonged operation.
