Original Nissan 5W40 engine oil: Complete selection and replacement guide

Owning a Japanese car requires a special approach to maintenance, especially when it comes to choosing lubricants. Nissan 5W40 oil original is one of the most popular solutions for owners of crossovers and sedans equipped with modern gasoline and diesel engines. This product was developed by the concern's engineers specifically for operation in harsh winters and hot summers, providing reliable protection for all engine components.

The auto chemical market is oversaturated with offers, and you can find genuine oil becomes a real problem for the car owner. Counterfeits can lead to critical failures that will not be recognized under warranty. In this article we will look in detail at how to distinguish the original from the counterfeit, what are the features of 5W40 viscosity and why this particular standard is often recommended by manufacturers for models Nissan Qashqai, X-Trail And Teana.

Choosing the right lubricant is not just a matter of instructions, but a way to extend the life of your car by tens of thousands of kilometers. We will pay attention not only to technical characteristics, but also to actual methods of checking the canister when purchasing, so that you can be confident in the quality of the product being filled.

Technical characteristics and purpose of viscosity 5W40

Motor oil 5W40 belongs to the class of all-season lubricants, which makes it a universal choice for most regions of Russia and the CIS countries. The first number “5” indicates low temperature viscosity, allowing the engine to start at temperatures down to -30°C without placing excessive stress on the starter and battery. The second number “40” characterizes high-temperature viscosity, which remains stable at engine operating temperature, preventing rupture of the oil film.

For engines Nissan With direct fuel injection and turbocharging, this viscosity is optimal. It provides quick access of oil to friction units during cold starts, while simultaneously creating a durable protective layer at high speeds. Usage original oil guarantees compliance with all specifications API SN And ACEA, which are required by modern power units of the Japanese brand.

It is important to understand that failure to comply with viscosity recommendations can lead to increased fuel consumption or, conversely, to engine overheating. If you operate the car mainly in city conditions with frequent traffic jams, oil with the index 5W40 demonstrates better stability indicators compared to liquid analogues such as 0W20.

How to recognize a fake: external signs of the original

Counterfeit products often copy packaging design with high accuracy, but an attentive buyer will always be able to spot discrepancies. The first thing you should pay attention to is the quality of the plastic canister. Original Nissan packaging It is made of durable, matte plastic that does not have a strong chemical odor. On fakes, the plastic is often too glossy, thin, or has burrs at the seams.

Pay special attention to the label and barcode. On genuine product barcode applied clearly, without blurred edges and can be checked through special applications or on the official website. The production date and batch number should be stamped on the bottom of the canister or on the neck, and not just printed on a sticker. If the numbers are easily erased with a fingernail, this is an obvious fake.

Another important marker is the lid. The original Nissan oils The lid has a special protective seal, which breaks with a characteristic sound when first opened. The color of the lid should perfectly match the color of the canister body, and the seal itself should fit tightly to the neck without gaps.

• 🔍 Check the print quality: the original text is clear, without “floating” letters or paint stains.
• 🔍 Inspect the bottom of the canister: the original has raised markings with the production date and batch number.
• 🔍 Compare the weight: the original canister of oil weighs a strictly defined amount indicated on the label, a fake one may be lighter due to the savings on volume.

Nissan Engine Compatibility and Specifications

Concern Nissan Motor Co. develops its own oil quality standards that take into account the operating characteristics of their engines. For motors of the family MR, QR and diesel units YD synthetic oil is ideal 5W40. It has the necessary detergent and dispersant properties, preventing the formation of soot and sludge in the lubrication channels.

A feature of the original oil is its compatibility with variable valve timing systems (CVTC). These systems are very sensitive to oil viscosity and using the wrong product can result in malfunctions and errors on the instrument panel. Original oil guarantees smooth operation of hydraulic tensioners and couplings.

For diesel versions of models Patrol or Navara 5W40 oil is also an excellent choice, as it contains a package of additives that neutralize the acidic combustion products of diesel fuel. This prevents corrosion of internal engine surfaces and extends the life of the turbocharger.

⚠️ Warning: Do not attempt to mix genuine Nissan oil with products from other brands, even if they have similar specifications. Differences in the chemical composition of additives can lead to sedimentation and loss of lubricity.

Oil change procedure and necessary tools

Changing engine oil is a procedure that is recommended to be carried out regularly, based on mileage or operating time. For cars Nissan The replacement interval is usually 10,000 km, but in urban use with traffic jams it is better to reduce it to 7,000–8,000 km. To carry out the work you will need not only original oil, but also a new oil filter, as well as a key for the drain plug.

Before starting work, it is necessary to warm up the engine to operating temperature so that the oil becomes more liquid and drains faster from the sump. After this, the car must be placed on a lift or inspection pit. It is important to follow safety precautions and use protective gloves as the used oil can be very hot.

The replacement process involves unscrewing the drain plug, waiting for the fluid to completely drain, replacing the filter and filling in new oil. After filling, you need to check the oil level using a dipstick or through the on-board computer if the car is equipped with a level control system. You need to fill strictly to the mark MAX, without exceeding it, since excess oil can lead to squeezing out the seals and damaging the catalyst.

What to do if you overfilled the oil?

If the oil level exceeds the maximum mark, the excess must be drained. This can be done through the drain hole, slightly loosening the plug, or using a syringe and tube through the dipstick hole. Overfilling is dangerous due to foaming of the oil and failure of the crankshaft seals.

After changing the oil, be sure to start the engine and let it idle for a few minutes. Make sure the oil pressure light on the dashboard is off and there are no leaks around the drain plug or filter. Only after this can you hit the road.

Comparison of original oil with analogues

Many car owners are wondering whether it is worth overpaying for original Nissan oil or you can use high-quality analogues. Of course, there are excellent products on the market from brands such as Mobil, Shell or Liqui Molythat meet the manufacturer's specifications. However, the original oil has the advantage of guaranteed compliance with all internal standards Nissan.

Analogues may differ in their additive package, which affects cleaning properties and wear protection. While some brands focus on fuel efficiency, Genuine Nissan 5W40 oil is balanced to maximize engine durability under real-world driving conditions, including aggressive driving styles.

Additionally, using original oil is often required to maintain your new vehicle warranty. Dealers may refuse to repair an engine under warranty if they find oil in it that does not meet the specifications, even if it is a high-quality analogue. Therefore, for new cars the choice is in favor original is the most reasonable.

Parameter	Original Nissan 5W40	High-quality analogue	Cheap substitute
CVTC Compatible	100%	90-95%	Low
Stability at high temperatures	High	Medium/High	Low
Cleaning properties	Optimal	good	Satisfactory
Risk of counterfeiting	High (requires verification)	Medium	Very tall

⚠️ Attention: Buying oil on tap in unfamiliar stores is strictly prohibited. You cannot be sure of the origin of the product, its freshness or correct storage conditions.

Where and how to buy oil correctly

Find original Nissan oil 5W40 available at official dealerships, specialized auto stores and trusted online platforms. When purchasing from a dealership, you are guaranteed to receive an original product, but the price may be significantly higher than the market average. But in specialized stores you can often find good discounts and bonuses.

When ordering online, carefully study reviews about the seller and check for quality certificates. Never agree to buy oil at a suspiciously low price - this is a sure sign of a fake. Original oil cannot cost less than its production and logistics costs.

If you buy oil from a physical store, do not hesitate to ask to see the certificate of conformity. The original must have clear seals and signatures of the responsible persons. Also pay attention to the storage conditions: the canisters should not be placed in direct sunlight or outside during the cold season, as this may affect the quality of the product.

• 🛡️ Buy only from official dealers or large auto store chains.
• 🛡️ Request a cash receipt and warranty documents for the product.
• 🛡️ Check the integrity of the packaging before paying for your purchase.

Frequent errors during operation and maintenance

Even using original oil, the car owner may make mistakes that will negate all the benefits of the product. One of the most common mistakes is ignoring replacement intervals. Over time, oil loses its properties, oxidizes and becomes contaminated with combustion products. Extending the replacement interval “by eye” can lead to coking of the engine.

Another mistake is using a low-quality oil filter. Cheap filters often do not have a check valve, which is why when the engine is stopped, the oil flows back into the sump, and the next time the engine is started, oil starvation occurs for several seconds. For Nissan It is better to use original filters or proven high-quality analogues.

It is also important to monitor the oil level. A low level leads to overheating and wear, and a high level leads to foaming and oil entering the crankcase ventilation system. Regularly checking the oil level through the dipstick should become a habit, especially before long trips.

Don't forget about the quality of the fuel. Using low-quality gasoline or diesel accelerates oil degradation, as combustion products enter the crankcase. In such conditions, it is recommended to reduce the oil change interval by 15-20%.

How often do you need to change Nissan 5W40 oil?

The official regulations suggest replacement every 10,000 km or once a year. However, for urban driving conditions with frequent traffic jams, it is recommended to change the oil more often - every 7,000–8,000 km, so that the engine operates in optimal conditions.

Is it possible to mix Nissan 5W40 oil with other brands?

It is strictly not recommended to mix oils from different manufacturers, even if they have the same viscosity 5W40. Differences in additive chemistry can result in unpredictable reactions, sludge formation, and loss of protective properties.

How to distinguish original Nissan oil from a fake by appearance?

Pay attention to the quality of the plastic of the canister (it should be matte and durable), the clarity of the label printing, the presence of a protective seal on the lid and the production date stamped on the bottom. The barcode must be readable and verifiable.

Does oil affect fuel consumption?

Yes, high-quality oil with the correct viscosity reduces friction in the engine, which can slightly reduce fuel consumption. However, the main factor is the condition of the engine itself and driving style.

⚠️ Attention: If after changing the oil there is extraneous noise or the color of the exhaust gases has changed, stop immediately and check the level and quality of the filled fluid. You may have become a victim of a counterfeit.
