The 2013 model year marked a definitive shift toward thinner lubricants to achieve tighter internal tolerances and improved fuel economy. Every gasoline engine offered in the 2013 Ram 1500—the 3.6L Pentastar V6, the 4.7L V8, and the 5.7L HEMI V8—utilizes SAE 5W-20 as the primary recommended viscosity. This specific weight provides critical quality protection during cold starts, where most engine wear occurs, while maintaining enough film strength at operating temperatures to protect the valvetrain.
Beyond simple viscosity, the oil must meet the Chrysler Material Standard MS-6395. This is not merely a suggestion; it is a mandatory specification for maintaining powertrain warranty. MS-6395 involves a rigorous series of tests, including a two-year field trial, to ensure the oil resists thermal breakdown and sludge formation specifically in Chrysler-designed engines. When browsing the oil aisle, look for the API Certified ‘Starburst’ symbol on the container. This reliable indicator confirms the oil meets the latest performance standards set by the American Petroleum Institute.
While old-school logic suggested moving to 10W-30 for “better protection,” modern Ram engines feature hydraulic systems and variable valve timing (VVT) that rely on the specific flow rates of 5W-20. Thicker oil can delay the response of these systems, leading to sluggish performance and potential diagnostic trouble codes.
For owners seeking a trusted brand, Pennzoil Platinum Full Synthetic and Valvoline Advanced Full Synthetic are two prominent options that explicitly list MS-6395 compliance on their labels. While conventional oils exist in 5W-20, a full synthetic lubricant offers superior resistance to oxidation and better flow in extreme climates, making it the professional choice for high-value truck engines.
Engine-Specific Oil Capacity and Filter Specs for the 3.6L Pentastar V6
The 3.6L Pentastar V6 was a relatively new addition to the Ram 1500 lineup in 2013, bringing with it a unique maintenance profile. Performing a complete oil and filter change on this engine requires exactly 6.0 quarts (5.6 liters) of SAE 5W-20 oil. Unlike the V8 options, the Pentastar utilizes a modern cartridge-style oil filter (Mopar MO-349) located on top of the engine, rather than a traditional metal spin-on canister underneath.
This design is more environmentally friendly but requires a nuanced approach during service. The oil filter housing is made of a high-strength polymer, which is susceptible to cracking if handled aggressively. The expert recommendation is to use a 24mm socket and a torque wrench to tighten the cap to exactly 25 Nm (18 ft-lbs). Over-tightening this cap is a common pitfall that leads to oil cooler leaks, a repair that can cost hundreds of dollars in labor.
The 2011-2013 Pentastar engines use a specific cartridge design that differs from the 2014+ models. Ensure you purchase the Mopar MO-349 or an equivalent that includes the correct O-ring. Using the later-model filter will result in a bypass of the filtration media, sending unfiltered oil through your engine.
The Pentastar’s variable displacement oil pump is also highly sensitive to oil quality. This pump adjusts the flow rate based on engine load and RPM to reduce parasitic drag. Using the correct 5W-20 viscosity ensures that the hydraulic pressure required to switch between high and low-pressure modes remains within the factory-specified window.
The 5.7L HEMI V8: Why Multi-Displacement System (MDS) Demands 5W-20
The legendary 5.7L HEMI V8 is the most popular engine in the 2013 Ram 1500, but it is also the most demanding regarding lubrication. The HEMI requires 7.0 quarts (6.6 liters) of SAE 5W-20 with a filter change. The primary driver for the strict 5W-20 requirement is the Multi-Displacement System (MDS), which deactivates four cylinders during light-load cruising to save fuel.
The MDS relies on complex hydraulic lifters and solenoids that use oil pressure as the switching medium. The system is calibrated for a specific 0.5-second response time for MDS solenoid activation. If a heavier oil, such as 5W-30 or 10W-30, is used, the oil’s flow rate is too slow to adequately fill or drain the lifter passages. This often results in a P0521 (Oil Pressure Sensor Range/Performance) or MDS Not Ready code, accompanied by a noticeable drop in fuel economy and a Check Engine Light.

Professional technicians often recommend high-quality synthetic lubricants to mitigate the infamous ‘HEMI Tick.’ While some ticking is normal due to the fuel injectors, persistent valvetrain noise is often caused by oil starvation at the lifters during cold starts. A premium synthetic 5W-20 that meets MS-6395 provides better film retention, ensuring that these critical components are lubricated the moment the engine turns over.
Oil Specifications for the 4.7L V8 Engine Option
The 4.7L V8 was in its final production year for the Ram 1500 in 2013. Often overlooked in modern guides, this engine is a rugged, overhead-cam design that requires 7.0 quarts (6.6 liters) of SAE 5W-20. Unlike its Pentastar stablemate, the 4.7L uses a traditional spin-on oil filter, specifically the Mopar MO-899 (or equivalent).
Because the 4.7L is based on an older Magnum architecture, it has higher thermal demands on its seals and gaskets. Using a trusted synthetic blend or full synthetic is highly beneficial here to prevent the hardening of the valve stem seals—a common issue on high-mileage 4.7L engines. Additionally, the 4.7L is notorious for slow drips at the oil pan drain plug. A professional-grade sealing washer (either Mopar OEM or a high-quality copper crush washer) should be replaced during every service to ensure a leak-free seal on the engine block.
Understanding the Oil Life Monitoring System (OLMS) and Service Intervals
The 2013 Ram 1500 features an intelligent Oil Life Monitoring System (OLMS). This isn’t a simple mileage counter; instead, it utilizes a software-based algorithm that calculates oil degradation based on engine temperature, idling time, load, and ambient temperature. Under ideal highway driving conditions, the system may allow for a maximum interval of 10,000 miles or 12 months.
However, for most Ram owners, a ‘Severe Duty’ cycle is more realistic. If you frequently tow trailers, drive in dusty off-road conditions, or endure extended idling in cold climates, expert maintenance schedules suggest changing the oil every 5,000 to 7,500 miles. Field data shows that trucks used primarily for short-distance towing in urban areas may see their monitor reach 0% as early as 4,000 miles. Regardless of what the monitor says, Ram specifies that the oil must be changed within 500 miles of the ‘Oil Change Required’ message appearing on the dashboard.
