Consistent oil pressure is the only way to prevent lifter failure, and this VIPCAR pump delivers exactly that. It is designed to match or exceed factory specifications, making it a reliable choice for high-mileage trucks.
If you are doing a timing chain service or noticing a dip in pressure, this is the component you want. It is built from high-quality materials that handle the heat of a V8 engine without breaking a sweat. It provides the reliable performance needed for daily driving and heavy work alike.

2. WIX XP High Performance Engine Oil Filter for Dodge Ram 1500 5.7L HEMI V8
🌟 Key Features That Stand Out
- ✓ Synthetic Media: Designed to handle the chemical properties of high-end synthetic oils.
- ✓ 99% Efficiency: Traps particles as small as 23 microns to keep oil pure.
- ✓ Long Intervals: Rated for up to 20,000 miles, perfect for long-distance drivers.
- ✓ Heavy-Duty Housing: Resists bursting even under the high-pressure cold starts typical of the Hemi.
- ✓ Silicone Anti-Drainback: Keeps oil in the filter to prevent dry starts.
💡 Why We Recommend It
When it comes to filters, WIX XP is arguably the best oil for 2018 Ram 1500 5.7 Hemi accessory you can buy. Standard filters use paper media that can break down over time, but the synthetic media in the XP version stays strong. It provides superior filtration during extreme driving conditions like towing or stop-and-go traffic.
We recommend this because it offers the ultimate protection against engine wear. The Hemi engine is sensitive to debris, and this filter ensures that even the smallest contaminants are captured. It is the perfect partner for high-mileage synthetic oils.
🎯 Best For
This product is ideal for: Truck owners who use full synthetic oil and want the longest possible interval between changes.
⚖️ Pros and Cons
✅ Pros
- Premium synthetic filtration
- Prevents dry start wear
- Sturdy metal end caps
- Great for towing trucks
❌ Cons
- Higher price than standard WIX
- Can be hard to remove without a tool
💬 What Customers Say

3. Engine Oil Measuring Dipstick for Dodge Ram 1500 5.7L and 6.4L HEMI V8 Engines
🌟 Key Features That Stand Out
- ✓ Stainless Steel: High-grade metal prevents rust and corrosion inside the tube.
- ✓ Perfect Length: At 34.33 inches, it matches the factory specs for exact readings.
- ✓ Direct Replacement: Swaps out with part number 53021321AK effortlessly.
- ✓ Clear Markings: Easy-to-read “Safe” zone ensures you never overfill or underfill.
- ✓ Heat Resistant Handle: The plastic handle won’t degrade under high engine bay heat.
💡 Why We Recommend It
Checking your oil is the most basic maintenance task, but a broken or rusted dipstick makes it impossible. This A-Premium dipstick is the best value because it provides a clear, accurate reading for a fraction of the cost of a Mopar replacement. It feels sturdy and fits snugly into the dipstick tube without vibrating.
If your original dipstick handle has snapped off or the cable has become frayed, this is a must-buy. It gives you peace of mind knowing exactly where your oil level sits, which is vital for the 5.7 Hemi engine which can be sensitive to oil volume.
🎯 Best For
This product is ideal for: Ram owners with broken or hard-to-read factory dipsticks who want a reliable replacement on a budget.
⚖️ Pros and Cons
✅ Pros
- Very affordable price
- Rust-resistant materials
- Highly accurate markings
- Fits 5.7 and 6.4 engines
❌ Cons
- Handle is bright yellow plastic
- Can be stiff to insert the first few times
💬 What Customers Say

4. Baffled Passenger Side Oil Catch Can for Dodge Ram 1500 5.7L HEMI 2021-2023
🌟 Key Features That Stand Out
- ✓ Baffled System: Internally designed to separate oil and air efficiently.
- ✓ Aluminum Body: Lightweight and corrosion-resistant for long-term use.
- ✓ Traps Vapors: Keeps blow-by oil out of your intake manifold.
- ✓ Easy Drain: Simple screw-off bottom makes cleaning a breeze.
- ✓ Direct Fit: Mounting brackets are shaped specifically for the Ram engine bay.
💡 Why We Recommend It
One of the hidden secrets to engine longevity is an oil catch can. In the 5.7 Hemi, oil vapors from the crankcase are fed back into the intake, which can lead to carbon buildup on valves. This catch can “catches” that oil before it reaches your engine, keeping your combustion chamber much cleaner.
It is made of sturdy aluminum and fits perfectly on the passenger side. By removing this oil from the intake stream, you also reduce the chance of engine knock, which the Hemi’s computer is very sensitive to. It’s an easy mod that pays for itself in engine health.
🎯 Best For
This product is ideal for: Performance-minded truck owners who want to prevent carbon buildup and keep their intake clean.
⚖️ Pros and Cons
✅ Pros
- Reduces carbon buildup on valves
- High-quality aluminum finish
- Increases combustion efficiency
- Very easy bolt-on install
❌ Cons
- Must be emptied every oil change
- Hoses can be a bit short for some builds
💬 What Customers Say
“Installed this on my 2022 and was shocked how much oil it caught in just 2,000 miles. Keeps that junk out of my engine!”
— Verified Buyer
“Looks great under the hood and works as advertised. The bracket is very secure and doesn’t rattle.”
— Verified Buyer

- ✓ High-Strength Steel: Chains are heat-treated for maximum durability and stretch resistance.
- ✓ Precision Gaskets: Comes with all the necessary seals to ensure a leak-free installation.
- ✓ OEM Spec: All parts meet or exceed the original factory dimensions and performance.
💡 Why We Recommend It
If you are hitting the 100,000-mile mark, this kit is the best way to ensure your Hemi stays healthy for the next decade. Buying these components as a kit saves a massive amount of money compared to buying them individually. The inclusion of a high-quality oil pump and water pump makes this a total engine refresh in a box.
The timing chain is the most critical link in your engine. If it stretches, your performance and fuel economy suffer. This kit replaces all wear items at once, preventing future breakdowns and saving on labor costs if you are paying a mechanic to go that deep into the motor.
🎯 Best For
This product is ideal for: High-mileage truck owners looking for a comprehensive engine refresh or major service.
⚖️ Pros and Cons
✅ Pros
- Unbeatable value for the bundle
- Fixes multiple potential failure points
- Premium heat-treated components
- Perfect for heavy-use trucks

6. Valvoline Extended Protection Full Synthetic 5W-30 Motor Oil for Ram 1500 5.7L HEMI V8
🌟 Key Features That Stand Out
- ✓ Dual Defense Additive: Combines wear-resistant boosters with a fortified detergent system.
- ✓ 60% Stronger Wear Protection: Far exceeds industry standards for engine life.
- ✓ 40% Better Deposit Defense: Keeps the interior of your V8 engine spotless.
- ✓ Friction Reduction: Advanced synthetic formula allows parts to glide more easily.
- ✓ Extended Drain: Specifically formulated for long-distance drivers who want fewer oil changes.
💡 Why We Recommend It
Valvoline Extended Protection is widely considered the best oil for 2018 Ram 1500 5.7 Hemi by those who understand wear protection. While 5W-20 is the factory standard, many Hemi owners switch to 5W-30 for better protection at high temperatures. This Valvoline formula is incredibly stable under heat, preventing the oil from thinning out when you’re working the truck hard.
This oil excels at cleaning out the sludge that can clog up the MDS (Multiple Displacement System) lifters. By keeping the oil passages clear, it ensures your engine can switch between 4 and 8 cylinders smoothly without any mechanical hiccups. It is the gold standard for long-term Hemi care.
🎯 Best For
This product is ideal for: Ram owners who want the absolute best wear protection and are looking to extend the life of their engine.
⚖️ Pros and Cons
✅ Pros
- Industry-leading wear boosters
- Keeps high-heat engines clean
- Reduces engine noise noticeably
- Great for high-mileage trucks
❌ Cons
- More expensive than standard synthetic
- Heavier weight (5W-30) might slightly impact MPG
💬 What Customers Say
“I’ve used Valvoline in my Hemi since day one. Currently at 180,000 miles with zero engine issues. The Extended Protection is worth the extra few bucks.”

7. FRAM Ultra Synthetic High Performance Engine Oil Filter for Ram 1500 5.7L HEMI V8
🌟 Key Features That Stand Out
- ✓ Dual-Layer Media: Features a unique synthetic blend that traps and holds more dirt.
- ✓ SureGrip Coating: The rough texture on the bottom makes it easy to install or remove with oily hands.
- ✓ High Capacity: Engineered to last for up to 20,000 miles of engine protection.
- ✓ Silicone Anti-Drainback: Maintains oil pressure at startup by keeping the filter full.
- ✓ Metal Screen Backing: Adds structural integrity to the media to prevent collapsing.
💡 Why We Recommend It
The FRAM Ultra Synthetic is a top-tier choice for owners who want maximum protection without the boutique price tag. Unlike the basic orange FRAM filters, the Ultra line uses dual-layer synthetic media and metal end caps. It is a very robust filter that can handle the high-flow requirements of the Hemi V8.
One of the best things about this filter is the SureGrip coating. If you’ve ever struggled to get an oil filter off a Ram, you know how tight the space can be. This grip makes the job much faster. It’s a high-performance part that is widely available and extremely reliable.
🎯 Best For
This product is ideal for: DIY enthusiasts who want a high-performance filter that is easy to install and remove.
⚖️ Pros and Cons
✅ Pros
- Unbeatable grip for removal
- Long-lasting synthetic media
- Silicone valve prevents dry starts
- Very high dirt-holding capacity
❌ Cons
- O-ring needs careful lubrication
- Slightly more expensive than generic options

- ✓ Efficient Cooling: Designed to lower oil temperatures during high-load operations.
- ✓ Durable Gaskets: Includes high-quality seals to prevent common oil-to-coolant leaks.
- ✓ Lightweight Design: Aluminum construction allows for fast heat dissipation.
💡 Why We Recommend It
Oil coolers are a common failure point on modern trucks, often leading to oil and coolant mixing. This replacement unit is essential if you notice milky oil or oil in your radiator. It is built to original equipment standards, meaning it will bolt right into place without any modifications to your Ram 1500.
Because it supports both the 5.7L and 3.6L engines, it’s a versatile part to have. Keeping your oil cool is vital for maintaining viscosity, especially if you live in a hot climate or use your truck for hauling heavy loads regularly. This part ensures your oil can do its job without overheating.
🎯 Best For
This product is ideal for: Truck owners dealing with leaking oil coolers or those wanting to prevent catastrophic oil/coolant mixing.
⚖️ Pros and Cons
✅ Pros
- Prevents engine overheating
- Direct bolt-on replacement

💡 Why We Recommend It
When your oil pump begins to fail, your whole engine is at risk. This high-pressure replacement is a great alternative to the expensive OEM pump. It provides the necessary volume to keep the top end of the engine lubricated, which is where most Hemi failures occur. It’s a solid piece of hardware that does its job quietly and effectively.
The build quality on this pump is impressive, featuring tight tolerances that prevent internal bleed-off. It’s a great choice for anyone looking to restore their engine’s oil pressure to like-new levels. Whether you’re daily driving or using your truck for heavy work, this pump is up to the task.
🎯 Best For
This product is ideal for: Ram owners who need a cost-effective way to restore engine oil pressure and protect their lifters.

10. K&N Cold Air Intake System with High Flow Filter for Ram 1500 5.7L HEMI
🌟 Key Features That Stand Out
- ✓ Dyno Tested Power: Guaranteed to increase horsepower and torque in the 5.7L Hemi.

- ✓ Improved Sound: Gives your truck a deeper, more aggressive growl under acceleration.
- ✓ Better Towing: Improves throttle response when pulling heavy loads uphill.
💡 Why We Recommend It
While not an oil part, air filtration is directly linked to oil cleanliness. A dirty intake lets dust into the engine, which then ends up in your oil. This K&N system is the best for performance because it opens up the air pathways, allowing the engine to breathe better. It also makes the truck sound incredible when you step on the gas.
We recommend it for anyone who wants to wake up their 2018 Ram. It installs in less than an hour with basic hand tools. Plus, because you can wash the filter, you’ll never have to buy another air filter for as long as you own the truck. It’s a performance upgrade that makes sense for the long haul.
🎯 Best For
This product is ideal for: Truck owners who want more power, better towing performance, and a louder exhaust note.
⚖️ Pros and Cons
✅ Pros
- Noticeable increase in power
- Reusable filter saves money
- Easy bolt-on installation
- Aggressive engine sound
❌ Cons
- Can be noisy for some drivers
- More expensive than drop-in filters
💬 What Customers Say

Complete Buying Guide for Best Oil For 2018 Ram 1500 5.7 Hemi
Essential Factors We Consider
When you are looking for the best oil for 2018 Ram 1500 5.7 Hemi, you must focus on viscosity and additives. The 5.7L Hemi uses a Multiple Displacement System (MDS) that requires 5W-20 oil to function correctly from the factory. However, many mechanics suggest that a high-quality 5W-30 synthetic oil provides better protection for the lifters and camshaft. Look for oils with high molybdenum content, as this helps reduce the friction that causes the famous Hemi Tick. Always pair your oil with a high-efficiency synthetic filter like a WIX XP or FRAM Ultra to keep contaminants away from your sensitive engine parts.
Budget Planning
Maintenance costs for a Ram truck can vary. A basic oil change with high-quality synthetic oil and a premium filter will usually cost between $70 and $100 if you do it yourself. While it might be tempting to save money on a cheap filter, spending an extra $10 now can save you a $4,000 engine repair later. If you are planning a high-mileage refresh, budgeting for a new oil pump and timing set is a smart move that will extend the life of your truck by another 100,000 miles.
Final Thoughts
Taking care of a Hemi V8 is all about consistency. Use the best synthetic oil you can afford, change it every 5,000 to 7,500 miles, and never skip on a high-quality filter. By keeping the oil clean and the pressure high, you ensure your 2018 Ram 1500 remains a powerful and reliable workhorse for many years to come.
Frequently Asked Questions
Q: What is the best oil weight for a 2018 Ram 1500 5.7 Hemi?
A: The owner’s manual recommends 5W-20 for MDS operation. However, many owners use 5W-30 for better high-temperature protection.
Q: How often should I change the oil in my 5.7 Hemi?
A: For best results and to prevent lifter wear, we recommend changing the oil every 5,000 to 7,500 miles, even if the truck says it can go longer.
Q: Does a catch can really help my engine?
A: Yes! A catch can prevents oil vapors from coating your intake valves, which reduces carbon buildup and helps maintain performance.
Q: Will using 5W-30 oil void my warranty?
A: Technically, you should follow the manual for warranty purposes. However, many owners switch once the warranty is over for better protection.
