Why Oil Capacity Matters for the Ram TRX
The Ram TRX isn’t your typical pickup. With its 702 horsepower and 650 lb-ft of torque, the supercharged HEMI is engineered for extreme performance, off-road capability, and towing power.
That kind of output puts serious stress on the engine, making oil quality and capacity crucial.
Oil doesn’t just lubricate moving parts, it also:
- Reduces friction and heat
- Cleans engine components from sludge and debris
- Protects against wear and corrosion
- Ensures consistent performance under high loads
If you underfill the oil, the engine won’t have enough lubrication, leading to overheating and premature wear. Overfilling, on the other hand, can cause aeration (foaming), which reduces oil pressure and may damage seals. That’s why sticking to the 7-quart capacity is so important.

Recommended Oil for the Ram TRX
The manufacturer recommends 0W-40 full synthetic motor oil, specifically formulated for high-performance engines. This viscosity grade is ideal because:
- 0W ensures smooth cold starts, even in winter conditions.
- 40 provides protection at high operating temperatures when the engine is under heavy load.
- Synthetic blends offer better resistance to thermal breakdown compared to conventional oils.
When to Change Oil in the Ram TRX
While oil capacity is important, so is knowing when to change it. For the Ram TRX, the general guideline is:
- Every 6,000–8,000 miles under normal driving conditions
- Every 3,000–5,000 miles under extreme driving conditions (towing, off-roading, high speeds, or dusty environments)
Modern Ram trucks feature an oil life monitoring system that alerts you when an oil change is due. Still, checking the dipstick regularly is recommended, especially if you push your TRX hard.

Signs You Need an Oil Change
Even with an oil life system, it helps to recognize the classic symptoms of old or low oil:
- Dark, gritty oil on the dipstick
- Engine knocking or ticking sounds
- Unusual exhaust smoke
- Burning oil smell inside the cabin
- Oil pressure warning light on the dashboard
If you notice any of these, check your oil level immediately and schedule a change if needed.

How to Check Oil in the Ram TRX
To make sure your oil is at the right level:
- Park on level ground and turn off the engine.
- Let it cool for at least 5–10 minutes.
- Open the hood and remove the dipstick.
- Wipe it clean, reinsert fully, then pull it out again.
- The oil should be between the “MIN” and “MAX” marks.
If it’s low, top it off with the same 0W-40 synthetic oil used during the last oil change.
DIY Oil Change vs. Service Center
Changing the oil on a Ram TRX can be done at home if you’re mechanically inclined, but many owners prefer a certified service center due to the truck’s performance nature. A professional oil change ensures:
- Correct oil capacity is used
- Proper filter installation
- Inspection for leaks and engine wear
- Waste oil disposal is handled properly
