The 5.7L HEMI in your Dodge Charger is a torquey, hardworking V8 with a couple of quirks worth respecting at oil change time. It runs the Multi-Displacement System (MDS), which drops to four cylinders to save fuel, and those MDS solenoids and lifters are picky about clean, correctly specced oil. Use the wrong viscosity or let the oil go too long and you can wake up to the dreaded HEMI tick, sluggish MDS engagement, or premature lifter wear. The factory calls for a 5W-20 oil meeting Chrysler MS-6395, and on some later model years a 0W-20, so getting this right is the single cheapest insurance you can buy for this engine.
We focused on full synthetic 5W-20 oils that actually carry the right approvals and have a real track record in HEMI engines. We weighed cold-start protection for those first noisy seconds, shear stability so the oil holds grade between changes, and high-mileage formulas for the many Chargers now past 75,000 miles. Below are seven oils we would confidently run in our own 5.7, ranked best first.

1. Pennzoil Platinum Full Synthetic 5W-20: Best Overall
Pennzoil Platinum is our top pick for the 5.7 HEMI because it hits the sweet spot of correct specification, clean base oil, and proven HEMI results. Its PurePlus base is made from natural gas rather than refined crude, which means it starts life with fewer impurities. In a HEMI that translates to quieter cold starts and cleaner MDS hardware, the two things this engine cares about most. It carries the Chrysler MS-6395 license outright, so you are not guessing about compatibility, and the detergent package does a genuinely good job keeping the lifter bores and solenoid passages free of varnish.
The honest weakness is that this is a standard full synthetic, not a high-mileage formula. If your Charger is past 120,000 miles and already burning a little oil or weeping from the valve covers, the slightly thicker high-mileage options lower on this list will do more for you. For a healthy 5.7 on a sensible 5,000 to 7,000 mile interval, though, Platinum is the one we reach for first, and the value is excellent given how clean it keeps the engine.
- PurePlus gas-to-liquid base oil that starts cleaner than crude-derived synthetics
- Carries the Chrysler MS-6395 approval the 5.7 HEMI is designed around
- Strong detergency that keeps MDS solenoid screens and lifters clean
Pros: Excellent cold-start flow that quiets the HEMI on first crank; Very low volatility, so it burns off slowly between changes; Widely stocked and easy to find in the correct 5W-20 grade
Cons: Not a dedicated high-mileage blend for very worn engines; Bottle and cap design can be a bit messy when topping off
2. Mobil 1 Extended Performance Full Synthetic 5W-20: Best for Long Intervals
Mobil 1 Extended Performance is the oil to choose if you run longer intervals or put real heat into your HEMI through towing, highway miles, or the occasional pull. The additive package is reinforced for extended service, and it resists the kind of high-temperature breakdown and sludge that can choke MDS solenoids over time. It carries the MS-6395 approval the 5.7 needs, and its shear stability means it holds 5W-20 grade rather than thinning out late in the interval.
The catch is psychological more than mechanical. The 20,000 mile rating on the bottle encourages owners to stretch drains, and on an MDS HEMI we would not. The solenoids and lifters stay healthiest on cleaner oil, so even with this premium product we suggest capping intervals around 7,500 to 10,000 miles. Used sensibly, this is a very durable oils you can put in a Charger, and it earns its place just behind our top pick.
- Reinforced additive system built for extended drain intervals
- Strong high-temperature deposit and sludge control
- Meets Chrysler MS-6395 for the 5.7 HEMI
Pros: Holds up better than most oils on longer change intervals; Excellent thermal stability for towing or spirited driving; Consistent quality and very wide availability
Cons: Long-interval claims tempt owners to stretch changes too far on MDS engines; Slightly firmer feel on cold starts than the Pennzoil
3. Valvoline Advanced Full Synthetic 5W-20: Best Value
Valvoline Advanced is the oil we recommend when you want a genuine full synthetic with real wear protection without paying for the premium tier. Valvoline loads it with extra antiwear additives, and that is exactly what a flat-tappet-adjacent valvetrain like the HEMI’s roller lifter setup appreciates. It meets MS-6395, flows well cold, and keeps the engine clean enough to avoid the MDS gremlins that plague neglected 5.7s.
Where it gives a little ground is base oil quality. It is a solid synthetic, but it does not have the gas-to-liquid pedigree of Pennzoil Platinum, so it volatilizes very slightly more under sustained heat. For most Charger owners on a normal 5,000 mile interval that difference is academic, and the value here is hard to argue with. This is the smart default for a daily-driven 5.7 that you want to protect without overthinking it.
- 50 percent more antiwear additives than required by industry minimums per Valvoline
- Good detergency that resists varnish in the valvetrain
- Meets Chrysler MS-6395 for the 5.7 HEMI
Pros: Strong wear protection at a very reasonable value; Easy to find in stores and online in the right grade; Clean, neutral cold-start behavior
Cons: Not quite the base-oil purity of Pennzoil Platinum; No high-mileage variant in this exact full synthetic line
4. Castrol EDGE Full Synthetic 5W-20: Best Wear Protection
Castrol EDGE is built around film strength, and that makes it a natural fit for owners who use the 5.7 the way it begs to be used. The Fluid Titanium technology physically toughens the oil film so it resists being squeezed out at the points of highest pressure, which in a HEMI means the lifter rollers, cam lobes, and bearings during hard pulls. It carries MS-6395, so the approvals box is checked, and it stays in grade impressively well when the engine is working.
The trade-off is at the other end of the temperature range. EDGE prioritizes load-carrying over the absolute thinnest cold flow, so on a cold morning you may hear a touch more valvetrain noise in the first second or two than you would with Pennzoil. It is never alarming, and it clears as soon as pressure builds, but it is a real and noticeable characteristic. If you drive your Charger hard, this is one of the best oils you can run.
- Fluid Titanium additive that strengthens the oil film under load
- Excellent resistance to thinning under high pressure and heat
- Meets Chrysler MS-6395 for the 5.7 HEMI
Pros: Holds its film strength under hard acceleration and heat; Very good protection for spirited and performance driving; Strong reputation in high-output V8 applications
Cons: Can feel marginally noisier on cold start than thinner-flowing oils; Premium positioning means lower everyday value than Valvoline
5. Mobil 1 High Mileage Full Synthetic 5W-20: Best High Mileage
Once a 5.7 HEMI crosses 75,000 to 100,000 miles, its priorities shift, and Mobil 1 High Mileage is built for that second act. It keeps the full synthetic backbone and MS-6395 approval, then adds seal conditioners that gently swell and soften aging rubber. On a Charger that has started weeping at the valve cover gaskets or losing a little oil between changes, this formula often slows that consumption noticeably and buys real time before you need to open the engine up.
Be clear about what it can and cannot do. The seal conditioners help marginal, hardened seals; they will not stop an already torn or blown gasket, and they cannot un-do worn rings. On a healthy low-mileage 5.7 this oil is simply unnecessary, and you are better off with our top pick. But for the large population of aging Chargers out there, it is the most targeted choice on this list and a genuinely useful tool.
- Added seal conditioners to revive aging valve cover and front seals
- Extra antiwear chemistry aimed at engines past 75,000 miles
- Meets Chrysler MS-6395 for the 5.7 HEMI
Pros: Helps reduce minor leaks and oil consumption on worn engines; Strong wear protection where it matters most on tired HEMIs; Keeps the full synthetic durability while addressing age
Cons: Overkill for a low-mileage engine still in great shape; Seal conditioners cannot fix an already failed gasket
6. Valvoline Full Synthetic High Mileage with MaxLife 5W-20: Best for High-Mileage Value
Valvoline MaxLife is the value play in the high-mileage category, and it is a strong one for HEMI owners who bought their Charger used with a patchy service history. Alongside the seal conditioners you expect from a high-mileage oil, MaxLife leans on extra detergents to actively clean up existing varnish and deposits, which is exactly what a neglected MDS engine often needs to free up sticky lifters and solenoids. It meets MS-6395 and keeps full synthetic durability.
That cleaning strength is also the one thing to watch. In an engine that is genuinely filthy inside, aggressively cleaning oil can occasionally dislodge a chunk of sludge and briefly upset oil flow, so if you are switching a high-mileage 5.7 onto MaxLife for the first time, run a shorter first interval and change the filter on time. Done that way, it is among the most cost-effective ways to rehabilitate and protect an older HEMI.
- MaxLife additive technology aimed at older, higher-mileage engines
- Seal conditioners plus extra cleaning agents to fight existing deposits
- Meets Chrysler MS-6395 for the 5.7 HEMI
Pros: Excellent value among full synthetic high-mileage oils; Good at cleaning up an engine with some neglect in its history; Helps manage minor leaks and consumption
Cons: Aggressive detergency can loosen deposits in a very dirty engine; Not as premium a base oil as the Mobil 1 high-mileage option
7. Royal Purple High Performance Full Synthetic 5W-20: Best Performance Specialty
Royal Purple is the enthusiast pick, the oil HEMI owners reach for when they have a cam, headers, or a tune and want every bit of protection under load. Its Synerlec additive forms a clingy ionic film that stays put on hot metal, which pays off in sustained high-rpm and high-load driving where ordinary oils can thin at the contact points. It is a proper API SP full synthetic in 5W-20 and suits the MS-6395 service requirement of the 5.7.
The reasons it sits at the bottom of an otherwise strong list are practical rather than technical. It commands a premium and offers the least everyday value of the seven, and it is simply harder to find on a shelf when you need oil in a hurry. For a stock, daily-driven Charger the mainstream oils above protect just as well for less fuss. But if your HEMI is modified or sees track and towing heat, Royal Purple is a specialist tool that earns its keep.
- Proprietary Synerlec additive that builds a tough ionic oil film
- Strong protection under high load and high temperature
- API SP rated full synthetic in the correct 5W-20 grade
Pros: Excellent film strength and antiwear performance under stress; Popular in the performance and modified HEMI community; Good thermal stability for track and towing heat
Cons: Premium positioning with the weakest everyday value here; Less universally stocked than the mainstream brands
Frequently Asked Questions
What oil does a 5.7 HEMI Charger take?
The factory specification for the vast majority of 5.7L HEMI Chargers is a 5W-20 full synthetic oil meeting the Chrysler MS-6395 standard. Some later model years switched to a 0W-20 recommendation for cold-weather flow and fuel economy, so always confirm against the cap and your owner manual. The most important point is the MS-6395 approval, because that standard is written specifically with the HEMI’s MDS solenoids and roller lifters in mind. Capacity is right around 7 quarts with a filter change, so buy enough oil to do the job properly and leave a little for topping off.
Can I use 5W-30 instead of 5W-20 in my 5.7 HEMI?
We do not recommend it as a routine choice. The 5.7 HEMI’s Multi-Displacement System uses oil pressure to actuate the MDS solenoids and deactivate cylinders, and that system is calibrated around the thinner 5W-20 film. Running a heavier 5W-30 can slow or roughen MDS engagement and is a common cause of complaints about jerky four-cylinder mode. In a genuinely high-mileage engine that is knocking and burning oil, some owners step up to a 5W-30 as a stopgap to quiet things down, and that is a defensible last resort, but for any healthy HEMI you should stick with the specified 5W-20.
How often should I change the oil in a 5.7 HEMI?
The onboard oil life monitor can stretch well past 8,000 miles, but for the longevity of an MDS HEMI we suggest a real-world interval of 5,000 to 7,000 miles with full synthetic. The lifters and MDS solenoids in this engine stay healthiest on clean oil, and the well-documented HEMI tick is far more common in engines run on long, neglected intervals. If you tow, drive hard, or live somewhere with extreme heat, lean toward the shorter end. Always change the filter at the same time, since a tired filter undermines even the best oil.
Does the right oil actually prevent the HEMI tick?
Oil is not a magic cure, but it is a major factor. The HEMI tick is usually traced to lifter and roller wear, and clean, correctly specced 5W-20 full synthetic on a sensible interval is the single best thing you can do to delay or avoid it. Oil with strong antiwear additives and good cold-start flow protects the valvetrain during those first noisy seconds when most wear happens. What oil cannot do is reverse damage that has already occurred. If your HEMI already ticks under load and the noise does not clear when warm, that points to mechanical wear that fresh oil will not fix.
Is full synthetic worth it for a 5.7 HEMI, or is conventional fine?
For this engine, full synthetic is genuinely worth it and is what we recommend across the board. The HEMI runs hot, the MDS hardware is sensitive to deposits, and synthetic oil resists the high-temperature breakdown and sludge that clog solenoid passages. Full synthetic also flows better on cold starts, which matters in an engine prone to startup valvetrain noise. Conventional oil can technically meet the viscosity, but it will not protect the MDS system or the lifters as well over time, and the modest extra cost of synthetic is cheap insurance against expensive lifter work down the road.
Our Verdict
For most 5.7 HEMI Charger owners, Pennzoil Platinum Full Synthetic 5W-20 is the oil we would put in our own car. It carries the right Chrysler MS-6395 approval, its gas-to-liquid base keeps the MDS hardware and lifters clean, and it delivers the quiet cold starts this engine needs, all at excellent value. Our runner up is Mobil 1 Extended Performance 5W-20, which is the better choice if you tow, run longer intervals, or push real heat through the engine and want maximum thermal stability. If your HEMI is past 75,000 miles, step over to Mobil 1 High Mileage instead, and whatever you choose, keep your intervals honest to protect this great V8 for the long haul.
