How To Change 2018 Nissan Altima SR Oil Like a Pro
Globally, car enthusiasts agree that keeping your vehicle in tune is half the battle. The 2018 Nissan Altima SR, with its refined 2.5-liter engine, offers smooth power but demands proper maintenance. If you are thinking, "Well, how can I change the oil on a 2018 Nissan Altima SR?", you are not alone. Most owners prefer doing it themselves to save time and control the quality of parts used. However, the process requires a few specific steps to avoid common pitfalls.
Before diving into the mechanics, let us discuss what you need. First, ensure you have a jack and jack stands or a car lift. You will also need an oil filter wrench, a drain pan, and a new oil filter. The 2018 Altima SR typically uses 0W-20 synthetic oil, and you will need about 4.7 liters (or roughly 5 quarts) to refill the system correctly. Always check your owner’s manual for exceptions, especially if your car has been driven in extreme climates.
Preparing the Vehicle for an Oil Change
Start by warming up the engine for a few minutes. Warm oil drains faster and carries more contaminants. Once the engine is warm, park the car on a flat, solid surface. Engage the parking brake and turn off the engine. This step is critical for safety, so do not skip it. If you use jack stands, lift the front of the car securely. Never rely solely on a hydraulic jack for this task.
Locate the oil drain plug under the engine. It is a large bolt on the bottom of the oil pan. Place your drain pan directly underneath to catch the used oil. Be careful; the oil can be hot and stink. Once the pan is positioned, loosen the drain plug with a socket wrench. Turn it slowly so you can catch the initial flow. Let the oil drain completely, which may take ten to fifteen minutes. While waiting, you can prepare the new oil filter.
Replacing the Oil Filter Correctly
The oil filter on the 2018 Altima is housed in a plastic cartridge located on the side of the engine block. It is not the traditional spin-on metal filter. To remove it, press down on the plastic cap and turn it counterclockwise. You will likely encounter resistance, so use your whole arm strength. Once removed, discard the old gasket inside the cap. It is often stuck due to dried sealant. Use a plastic scraper to remove it cleanly without scratching the housing threads.
Now, install the new filter. Before placing it, apply a small amount of fresh oil to the new gasket. This ensures a proper seal and makes the next replacement easier. Insert the new filter into the housing, tightening it by hand. Press down firmly and turn clockwise until it clicks. You should hear a distinct click, indicating the seal is engaged. Do not overtighten, as this can damage the plastic housing. This step is crucial for preventing future oil leaks.
Refilling the Oil and Checking Levels
With the filter in place, reinstall the drain plug. Apply a thin layer of oil to the washer to prevent leaks. Tighten it to the manufacturer’s specification, usually around 22 foot-pounds. Over-tightening can strip the threads in the oil pan. Next, pour the new 0W-20 synthetic oil into the filler cap at the top of the engine. Pour slowly to avoid spillage. Once you have added about 4.5 quarts, stop and wait a minute for the oil to settle into the pan.
After waiting, turn the ignition on without starting the engine. Let the oil pump run for a few seconds. Then, check the dipstick to see the level. Add oil gradually, a little at a time, until the level reaches the full mark. Do not overfill, as this can cause engine foaming and damage. Wipe the dipstick clean before each check for accuracy. Once satisfied with the level, replace the dipstick securely.
Final Steps and Disposal
Start the engine and let it idle for a minute. Watch for any signs of leaks around the drain plug and the filter housing. If you see any, shut off the engine immediately and re-tighten or replace the gasket. Once you are sure there are no leaks, turn off the engine. Let the car sit for a few more minutes, then check the dipstick again. This final check ensures the reading is accurate after circulation.
Dispose of the old oil and filter at an authorized recycling center. Do not dump it down the drain or in the trash. Many auto parts stores will take used oil for free. Reset the maintenance reminder on your dashboard by following the steps in your owner’s manual. Usually, this involves holding the trip reset button while turning the ignition on. Following these steps ensures your 2018 Altima SR performs optimally and lasts longer.
Frequently Asked Questions
- How often should I change the oil on a 2018 Altima SR? Nissan generally recommends every 5,000 to 7,500 miles, depending on driving conditions. If you drive in severe conditions, such as frequent short trips or extreme temperatures, change it more often.
- What type of oil is best for a 2018 Altima SR? 0W-20 synthetic oil is the standard factory specification. Using this viscosity ensures proper fuel economy and engine protection. Always look for the API donut seal or ILSAC certification on the oil bottle.
- Can I use a manual oil filter instead of the cartridge type? No, the 2018 Altima engine is designed for the cartridge-style filtration system. Attempting to use a spin-on filter will not fit and could cause severe engine damage.
- How much does a DIY oil change cost for an Altima SR? Expect to spend around $30 to $40 on synthetic oil and a filter. This is significantly cheaper than a professional service, which can range from $50 to $80.
