However, when purchasing, many are faced with confusion in the article numbers: the original codes differ depending on the volume of containers, the region of delivery, and even the production batch.

In this article we will analyze in detail all official oil articles Kixx 5W40, its technical characteristics, compatibility with specific models Nissan (from Qashqai to Patrol), and also give practical recommendations for verifying the authenticity of a product. We will pay special attention to the nuances of changing the oil, which even experienced car owners often miss - for example, the influence of 5W40 viscosity on the performance of turbocharged engines at extreme temperatures.

Official articles of Kixx 5W40 oil: how not to make a mistake when purchasing

Brand Kixx uses multiple coding systems for its products, which may confuse the buyer. Main articles for oil 5W40 (semi-synthetic and synthetic) are given below. Please note: codes may vary for European, Asian and American markets.

• 📦 1 l (plastic bottle): KXG5401 or KXG5401E (Europe)
• 📦 4 l (canister): KXG5404 or KXG5404A (Asia)
• 📦 5 l (canister): KXG5405 or KXG5405U (USA/Canada)
• 📦 20 l (barrel): KXG5420 (for service stations)
• 📦 60 l (barrel): KXG5460 (wholesale supplies)

Important: articles with suffix E or A often indicate regional adaptation of composition. For example, version KXG5404A may contain additional additives to protect against corrosion in high humidity conditions (relevant for Southeast Asia). In Russia and the CIS countries, articles without suffixes or with a letter are more common U (universal).

⚠️ Attention: Counterfeits with article numbers are common on the market KXG5401R or KXG5404P - such codes in the official catalog Kixx does not exist. Always check for the hologram on the lid and the barcode at the bottom of the canister.

Technical specifications: what do the 5W40 numbers hide?

Viscosity grade 5W40 means that the oil remains fluid at temperatures up to -30°C (digit 5W) and provides a stable oil film when heated to +40°C (digit 40). However, actual operating parameters Kixx 5W40 go beyond the standard description:

Parameter	Meaning	Note
Kinematic viscosity at 100°C	14.5–16.3 mm²/s	Optimal for turbocharged engines
Viscosity index	170–185	Above average for 5W40 (guarantees stability under temperature changes)
Flash point	230°C	Exceeds requirements API SN (minimum 220°C)
Base Number (TBN)	10.5 mg KOH/g	Suitable for engines with extended replacement intervals (up to 15 thousand km)
Sulfur content	<0.2%	Complies with environmental standards Euro 5/6

Feature Kixx 5W40 — use of technology Dual Protection System, which combines mineral and synthetic base oils with an additive package Infineum. This allows the product to more effectively combat deposits in systems VVT (variable valve timing), which is critical for modern engines Nissansuch as MR20DD or VR38DETT.

However, there is a nuance: when used in engines with a mileage of more than 200 thousand km, this oil may exhibit increased “carbon emissions” due to high fluidity. In such cases, it is recommended to reduce the replacement interval to 8–10 thousand km or switch to a viscosity 5W50.

Compatibility with Nissan models: which engines love Kixx 5W40

Oil Kixx 5W40 approved for use in most engines Nissan, but there are models for which it is ideal, and there are those where caution is required. Below is a detailed compatibility table taking into account design features:

• ✅ Ideal choice:
  • Qashqai J11 (engines MR20DD, R9M) - optimal viscosity for the system Start/Stop.
  • X-Trail T32 (engine MR20DD) - reduces timing chain noise.
  • Navara D40 (engine YD25DDTi) - compatible with particulate filter DPF.
• ⚠️ Limited Compatibility:
  • Patrol Y62 (engine VK56VD) - requires oil with a high molybdenum content (for example, Kixx G1 5W40).
  • GT-R R35 (engine VR38DETT) - only for everyday driving, not for the track.
  • Almera N18 (engine HR16DE) — increased fuel consumption is possible during aggressive driving.
• ❌ Not recommended:
  • Leaf (electric car) - does not require oil.
  • Juke 1.5 dCi (engine K9K) - it is better to use oil with a viscosity 5W30 and admission Renault RN0720.

For turbocharged engines (eg Pathfinder R52 with VQ35DD) Kixx 5W40 shows good results due to high thermal-oxidative stability. However, under extreme load conditions (towing, off-road), it is recommended to reduce the change interval by 30% or use oil with an approval Nissan KE900-99932 (original Nissan Oil).

Why is Kixx 5W40 not suitable for Juke 1.5 dCi?

Engine K9K (installed on Juke And Renault Captur) sensitive to high ash oils. Kixx 5W40 has an alkalinity number of 10.5, which is higher than recommended for this motor (maximum 9.5). This can lead to premature clogging of the diesel particulate filter. DPF and increased fuel consumption. For K9K oils with approval are optimal Renault RN0720, for example, Elf Evolution 900 NF 5W30 or Total Quartz INEO ECS 5W30.

How to distinguish an original from a fake: 7 key signs

Counterfeit oils Kixx are more common than competitors (for example, Mobil 1 or Castrol), due to the popularity of the brand in the budget segment. Here are proven ways to recognize counterfeits:

1. Hologram on the lid: The original canister has a hologram with a logo GS Caltex, which changes color when tilted. Counterfeits often imitate it with a sticker.
2. Barcode: There should be a barcode at the bottom of the canister that matches the code on the label. For fakes they are often different.
3. Oil color: The original has a golden-amber hue. Counterfeits may be cloudy or have a greenish tint.
4. Smell: Natural oil has a weak and neutral odor. Counterfeits often have a strong chemical smell.
5. Packing: The canister must be made of matte plastic with a clearly printed logo. Glossy or with blurry text is a sign of a fake.
6. Production date: The date on the original canister is laser-etched (not a sticker!). Format: YYYYMMDD.
7. Price: If the cost is 20% or more below the market average, this is a reason to check.

Additional test: drop oil on paper and wait 10 minutes. The original forms a uniform spot with a clear outline, while the fake is blurry with a dark halo. For reliability, you can check the batch by serial number on the website kixxoil.com (section Product Verification).

⚠️ Attention: Fake oil Kixx 5W40 often diluted with cheap mineral bases, which leads to the formation of sludge in the engine after 3–5 thousand km. Particularly dangerous for turbocharged engines (for example, X-Trail with MR20DDT), where this can cause the turbine to seize.

Step-by-step instructions for changing the oil: nuances for Nissan

Changing engine oil Nissan has its own characteristics related to the design of the pan and the location of the filter. Below are universal instructions taking into account model differences:

1. Preparation: Warm up the engine to operating temperature (60–70°C) so that the oil becomes more fluid. Place the car on a level surface and secure it with the handbrake.
2. Oil drain: Unscrew the drain plug (key on 14 or 17, depending on the model). For Qashqai J11 And The X-Trail T32 plug is located towards the rear of the pan. Place a container with a volume of at least 5 liters.
3. Filter replacement: Oil filter on most models Nissan located on top of the engine (for example, in Almera N18) or from the side (in Patrol Y62). Before installing a new filter, lubricate the rubber O-ring with fresh oil.
4. Filling with new oil: Fill in ~4.5 liters of oil (see the table below for the exact volume), then check the level with a dipstick. For dry sump engines (e.g. GT-R) the procedure is different - special equipment is required.
5. Control: Start the engine and let it idle for 2-3 minutes. Check for leaks and re-measure the oil level.

Model Nissan	Engine	Oil volume (l)	Features
Qashqai J11	MR20DD	4.8	The service interval needs to be reset after CONSULT-III.
X-Trail T32	MR20DD	5.1	Drain plug with magnet - clean it of metal shavings.
Navara D40	YD25DDTi	7.4	Use approved oil ACEA C3 for compatibility with DPF.
Patrol Y62	VK56VD	7.8	Changing the oil requires removing the crankcase protection.

For engines with system VVEL (For example, 370Z with VQ37VHR) after changing the oil, it is recommended to perform throttle valve adaptation via a diagnostic scanner. This is due to the operating features of the variable valve timing system.

💡

For engines Nissan with timing chain drive (for example, MR20DD) use of oil Kixx 5W40 allows you to reduce chain noise by 15–20% due to the high viscosity index (170+).
