Changing your oil is a straightforward task that any DIY mechanic can handle. Follow these steps carefully to ensure a safe and successful oil change.
Always prioritize safety. Wear appropriate personal protective equipment (PPE) and work on a level surface.
Tools and Materials You’ll Need
- Your chosen full synthetic engine oil (check capacity!)
- New oil filter (and possibly a new O-ring for cartridge filters)
- Oil filter wrench (specific to your filter type)
- Socket wrench and appropriate socket for the drain plug
- Drain pan (large enough for your Jeep’s oil capacity)
- Funnel
- Clean rags or shop towels
- Jack and jack stands (if needed for clearance)
- Wheel chocks
- Gloves and eye protection
- Torque wrench (for drain plug and filter housing)
Safety First: Preparing for the Job
- Park on a Level Surface: This ensures accurate oil level readings and prevents your vehicle from rolling.
- Engage Parking Brake: Always activate your parking brake.
- Chock the Wheels: Place wheel chocks behind the rear wheels (if lifting the front) or front wheels (if lifting the rear).
- Lift and Secure (If Needed): If you need more clearance, use a floor jack to lift the front of the vehicle. Place sturdy jack stands under the frame rails. Never work under a vehicle supported only by a jack.
- Allow Engine to Cool Slightly: Warm oil drains better, but hot oil can cause burns. Let the engine cool for 15-20 minutes after running.
Draining the Old Oil
- Locate the Drain Plug: Position your drain pan directly underneath the oil pan drain plug.
- Remove the Drain Plug: Using the correct socket, carefully loosen and remove the drain plug. Be prepared for oil to flow out immediately.
- Let it Drain Completely: Allow all the old oil to drain into the pan. This usually takes 10-15 minutes.
- Inspect the Drain Plug: Check the drain plug and its washer (gasket). If the washer looks compressed or damaged, replace it to prevent leaks.
- Reinstall the Drain Plug: Once drained, clean the drain plug and the area around the oil pan. Reinstall the drain plug and tighten it to the manufacturer’s specified torque (refer to your owner’s manual – overtightening can strip threads!).
Replacing the Oil Filter
The location and type of oil filter vary by engine. The 3.6L Pentastar V6 typically has a cartridge filter located on top of the engine, while HEMI engines usually have a spin-on filter underneath.
- Locate the Oil Filter: Identify your oil filter.
-
Remove the Old Filter:
- Spin-on Filter: Use an oil filter wrench to loosen and remove the old filter. Be ready for residual oil to spill.
- Cartridge Filter: Use a socket wrench to unscrew the filter housing cap. Carefully pull out the old filter element and replace the O-ring on the housing cap.
-
Prepare the New Filter:
- Spin-on Filter: Apply a thin film of new oil to the rubber gasket of the new filter.
- Cartridge Filter: Insert the new filter element into the housing.
-
Install the New Filter:
- Spin-on Filter: Screw the new filter on by hand until the gasket makes contact, then tighten an additional 3/4 to 1 full turn. Do not overtighten with a wrench.
- Cartridge Filter: Screw the housing cap back on and tighten it to the specified torque.
Refilling with New Oil
- Locate the Oil Fill Cap: It’s usually on top of the engine, clearly marked with an oil can symbol.
- Place the Funnel: Insert a clean funnel into the oil fill opening.
- Add New Oil: Slowly pour in the recommended amount of oil for your specific engine (e.g., 6 quarts for the 3.6L Pentastar V6).
- Check the Dipstick: After adding most of the oil, wait a few minutes for it to settle. Pull out the dipstick, wipe it clean, reinsert it fully, then pull it out again to check the level. It should be between the “MIN” and “MAX” marks. Add more oil slowly if needed.
- Start the Engine: Start your Jeep and let it run for a minute or two. Check for any leaks around the drain plug and oil filter. The oil pressure light should turn off.
- Re-check Oil Level: Turn off the engine, wait 5-10 minutes for the oil to settle, and check the dipstick again. Top off if necessary to reach the “FULL” mark.
- Reset the Oil Change Indicator: Consult your owner’s manual for instructions on how to reset the oil change reminder light on your dashboard.
Common Oil Change Mistakes and How to Avoid Them
Even seasoned DIYers can make mistakes. Being aware of these common pitfalls can save you time, money, and potential engine damage.
A little extra caution goes a long way in automotive maintenance.
Using the Wrong Oil Type or Viscosity
As we’ve covered, each engine has specific requirements. Using 5W-30 in an engine that calls for 5W-20, or a non-low-ash oil in an EcoDiesel, can lead to inadequate lubrication, premature wear, or DPF issues.
Always consult your owner’s manual and stick to the recommended oil specifications.
Incorrect 2016 Jeep Grand Cherokee Oil Capacity
Overfilling or underfilling is a common mistake. Too much oil can cause foaming (aeration), which reduces lubrication effectiveness and can damage seals. Too little oil leads to oil starvation and excessive wear.
Measure carefully, add slowly, and verify with the dipstick multiple times.
Failing to Replace the Drain Plug Gasket/Washer
The small gasket or crush washer on the drain plug is designed to create a tight seal. Reusing an old, compressed washer is a recipe for a slow, annoying oil leak.
Always replace this inexpensive part with each oil change.
Overtightening the Drain Plug or Oil Filter
This is a big one. Overtightening the drain plug can strip the threads in your oil pan, leading to an expensive repair or replacement. Overtightening a spin-on filter can deform the gasket, leading to leaks, or make it incredibly difficult to remove next time.
Use a torque wrench for the drain plug and follow the “hand-tight plus a quarter/half turn” rule for spin-on filters.
Not Cleaning Up Spills Properly
Oil spills can be slippery and dangerous. They also harm the environment. Always have rags ready and clean up any drips or spills immediately.
Dispose of used oil responsibly at a local recycling center or auto parts store.
Maintaining Optimal Oil Levels for Off-Road Adventures
If you’re taking your 2016 Jeep Grand Cherokee off the beaten path, maintaining optimal oil levels and knowing its capacity is even more critical. Off-roading puts extra stress on your engine and can lead to unexpected challenges.
A well-maintained engine is your best companion when far from civilization.
Before You Hit the Trail
Always perform a pre-trip inspection. Check your oil level on a flat surface before you head out. Ensure it’s at the “FULL” mark, not just “MIN.” Consider carrying an extra quart of the correct oil, especially on longer or more remote trips.
This can be a lifesaver if you encounter an unexpected leak or consume a little more oil than usual.
Impact of Steep Angles and Uneven Terrain
When traversing steep inclines or declines, or driving on heavily angled terrain, the oil in your pan can slosh around, potentially exposing the oil pump pickup tube. This can lead to temporary oil starvation, even if your overall oil level is adequate.
Keeping your oil level consistently at the full mark minimizes this risk. If you hear any unusual engine noises while at extreme angles, stop and assess the situation safely.
Monitoring Oil Pressure
Modern Grand Cherokees have an oil pressure gauge or warning light. Pay attention to it. A sudden drop in oil pressure, especially during or after navigating challenging obstacles, could indicate a problem.
If the oil pressure light comes on, safely pull over immediately and shut off the engine. Investigate the cause before continuing.
Dealing with Potential Leaks on the Trail
Rocks, branches, and rough terrain can cause damage. A punctured oil pan or a loose drain plug can lead to significant oil loss. If you notice an oil leak while off-roading:
- Stop Immediately: Turn off the engine to prevent further damage.
- Assess the Damage: If safe, inspect underneath your vehicle. Look for the source and severity of the leak.
- Temporary Fixes: For minor leaks, a temporary patch (e.g., using epoxy putty specifically designed for automotive repairs) might get you to safety.
- Signal for Help: If the leak is severe or unfixable, use your communication devices (satellite phone, two-way radio) to signal for help. Park rangers or experienced off-road guides can be invaluable in these situations.
- Avoid Driving Without Oil: Driving with insufficient oil will quickly destroy your engine. It’s better to wait for assistance.
Frequently Asked Questions About 2016 Jeep Grand Cherokee Oil Capacity
How often should I change the oil in my 2016 Grand Cherokee?
Most 2016 Grand Cherokees with synthetic oil can go 7,500 to 10,000 miles or 6-12 months, whichever comes first. However, if you do a lot of towing, off-roading, or short-trip driving, consider more frequent changes, possibly every 5,000 miles. Always refer to your owner’s manual and the vehicle’s oil change indicator system.
Can I mix different brands of oil if they are the same type and viscosity?
While generally not recommended as a regular practice, mixing different brands of full synthetic oil with the same API certification and viscosity (e.g., 5W-20 MS-6395) for a top-off in an emergency is usually acceptable. However, for a full oil change, stick to one reputable brand to ensure consistent performance and additive packages.
What happens if I put too much oil in my Grand Cherokee?
Overfilling can cause the crankshaft to churn the oil into a foam, reducing its lubricating properties. This “aerated” oil can lead to decreased oil pressure, increased engine wear, and potentially damage seals and gaskets due to excessive crankcase pressure. It’s best to drain the excess oil if you’ve overfilled significantly.
Is it okay to use conventional oil if my manual recommends synthetic?
No. Using conventional oil when synthetic is recommended can lead to accelerated engine wear, reduced fuel efficiency, and potentially void your warranty. Modern engines, including those in the 2016 Grand Cherokee, are designed with tighter tolerances and rely on the superior properties of synthetic lubricants.
Where can I dispose of used engine oil?
Never pour used engine oil down the drain or onto the ground. Most auto parts stores, service stations, and municipal recycling centers accept used engine oil for recycling. Collect it in a sealed, labeled container and drop it off responsibly.
