How Much Oil Does a 2013 Infiniti FX37 Need? Capacity & Change Tips
Whether you’re a seasoned mechanic or a DIY enthusiast, knowing the exact oil capacity for your 2013 Infiniti FX37 is essential for engine longevity. This 2013 Infiniti FX37 Oil Capacity Guide will walk you through the exact amount of oil you need and how to change it safely, so you can keep your vehicle running smoothly without over‑ or under‑filling.
2013 Infiniti FX37 Oil Capacity Guide
The 3.7‑liter V8 engine in the FX37 holds 6.5 quarts (6.2 liters) of oil when you replace the filter. That figure is the official specification from Infiniti and the best baseline for routine changes. If you’re using a different oil type or have a modified engine, the capacity can shift slightly, so always check the owner’s manual for your exact model and engine code.
Why Knowing Your Oil Capacity Matters
Oil does more than lubricate; it cools, protects, and cleans the engine. Overfilling can cause foaming and reduced oil pressure, while underfilling can lead to increased wear and overheating. Accurate measurement keeps your engine’s seals and bearings happy, prolonging the life of your FX37.
Engine Types and Their Oil Needs
Infiniti offers several engine variants in the FX37 lineup. The base V8 uses the capacity listed above, while high‑performance models might have a slightly larger oil capacity due to additional oil passages or upgraded cooling systems. Always match the capacity to your exact engine code—typically found on a placard inside the driver’s door jamb.
How to Check Your Oil Level
Checking oil before a change ensures you’re adding the right amount. Make sure the car is on level ground, let the engine cool for at least 10 minutes, and then pull the dipstick to check the level. If it’s below the “full” mark, add a little at a time until you reach the correct level.
Tools You’ll Need
- Socket set with a 10‑mm wrench for the drain plug
- Oil filter wrench
- Oil drain pan
- New oil filter (check OEM specs for filter part number)
- New engine oil (5W‑30 synthetic is recommended)
- Shop towels and a funnel
Step‑by‑Step Oil Change Instructions
Preparing the Vehicle
Park on a flat surface and engage the parking brake. Open the hood, locate the oil filler cap, and set aside a clean towel to wipe any spills. This keeps the engine compartment free of mess and prevents contamination.
Draining the Old Oil
Place the drain pan under the oil pan, unscrew the drain plug, and let the oil run out completely—usually takes 3–5 minutes. Once the flow stops, replace the drain plug with a new washer if recommended.
Replacing the Filter
Unscrew the old filter with the wrench, wipe the mounting surface, and install the new filter by hand until snug. A second turn with the wrench is optional but not necessary if you’re careful not to overtighten.
Adding Fresh Oil
Remove the filler cap, insert a funnel, and pour 6.5 quarts of the recommended oil. Check the level with the dipstick and top off as needed—only add small amounts at a time.
Final Checks
Replace the filler cap, start the engine, and let it run for a few minutes while watching for leaks. After a short drive, re‑check the dipstick to confirm the level remains within the optimal range.
Common Mistakes to Avoid
- Using the wrong filter size. Always match the OEM part number.
- Overfilling with too much oil. This can cause foaming and loss of pressure.
- Neglecting the drain plug washer. A missing washer can lead to slow leaks.
When to Add Oil Between Changes
If you notice the level dropping more than 1/2 quart between changes, it might be a sign of a small leak or increased consumption due to engine wear. In that case, add the missing amount and monitor closely. If the level drops rapidly, schedule a diagnostic check for potential leaks or engine issues.
