Oil Kixx PAO 5W-40 - one of the most talked about synthetic motor oils on the market, especially among car owners Nissan. Its unique polyalphaolefin (PAO) formulation promises superior engine protection in all operating conditions. But is this true in practice? In this article we will analyze the composition of the oil, its technical characteristics, compatibility with popular models Nissan (including Qashqai, X-Trail And Juke), and also analyze real reviews from car owners and experts.
Why exactly 5W-40? This viscosity class is considered universal for most modern engines, including turbocharged and naturally aspirated engines. Nissan. However, not all oils with this marking are the same - it all depends on the base base and additive package. Kixx PAO stands out because the manufacturer claims a 100% synthetic base without mineral components, which should guarantee stable properties throughout the entire service interval. But is this really so? Let's figure it out.
Composition and production technology of Kixx PAO 5W-40
Main difference Kixx PAO 5W-40 from competitors - use fully synthetic base based on polyalphaolefins (PAO). This is not just a marketing ploy: PAO synthetics have a more stable molecular structure compared to hydrocracking oils, which provides:
- 🔹 Minimum evaporation — the oil retains its volume and viscosity properties longer.
- 🔹 Oxidation resistance — extends the replacement interval without loss of protective properties.
- 🔹 Low temperature dependence — remains fluid at -30°C and does not liquefy at +150°C.
- 🔹 High viscosity index (more than 170) - guarantees stable operation over a wide temperature range.
Manufacturer (GS Caltex, South Korea) claims that the oil contains ester components as friction modifiers. This allows you to reduce wear on engine parts by 15–20% compared to traditional synthetic oils. However, independent laboratory tests (for example, from OilClub) show that the content of esters in Kixx PAO does not exceed 5–7% - this is enough to improve the lubricating properties, but not enough to position the oil as “ester”.
An important nuance: despite the declared 100% PAO base, the composition contains minimal proportions of hydrocracking (up to 3%) to adjust the viscosity properties. This does not degrade performance, but should be taken into account when choosing oil for engines with strict base requirements (for example, Nissan VR38DETT in GT-R).

- 📋 ACEA A3/B3, A3/B4 - Confirms stability under high loads.
- 📋 MB 229.5, VW 502.00/505.00 - compatibility with European cars (important for Nissan with engines Renault, for example, K9K in Terrano).
- 📋 Nissan Strong Save X - official approval for most brand models.
However, there is no approval API SP (latest standard for 2026), which may be a problem for new engines Nissan with the system Variable Compression Turbo (VC-Turbo), for example, in Altima or Skyline. In such cases, the manufacturer recommends using oils approved Nissan 0W-20 Gen-2.
If you are exploiting Nissan Qashqai J11 with engine MR20DD, check for approval ILSAC GF-5 on the canister. Kixx PAO 5W-40 It doesn’t have it, but it fits the rest of the parameters.
Compatibility with Nissan models: what does the manufacturer say?
Official dealers Nissan in Russia and Europe it is often recommended Kixx PAO 5W-40 for the following models:
- 🚗 Qashqai J10/J11 (engines MR20DE, M9R, R9M) - optimal for regions with cold winters.
- 🚗 X-Trail T31/T32 (including hybrid versions) - suitable for engines QR25DE, MR20DD.
- 🚗 Juke F15 (turbo engines MR16DDT) - provides protection under high loads.
- 🚗 Navara D40 (diesels YD25DDTi) — meets the requirements ACEA B4.
However, there are exceptions. For example, for Nissan GT-R (R35) with engine VR38DETT The manufacturer recommends oils with a viscosity 10W-60 and admission Nissan KE900-99932. Kixx PAO 5W-40 not suitable for this model due to insufficient high-temperature viscosity (HTHS = 3.7 mPa s versus the required 5.6+).
You should also avoid using this oil in old engines with high mileage (more than 200 thousand km), where there may be problems with oil starvation due to worn oil seals and oil rings. In such cases, it is better to choose an oil with a higher viscosity (for example, Kixx G1 10W-40).
CVT compatibility details
Nissan does not officially prohibit the use of Kixx PAO 5W-40 in engines coupled with CVTs (for example, in the Qashqai J11). However, it is important to monitor the condition of the oil in the box separately - its properties do not affect the life of the CVT, but aggressive driving with frequent engine overheating can accelerate wear of the variator.
Comparison with peers: which is better for Nissan?
To understand how much Kixx PAO 5W-40 compares favorably with its competitors, let’s compare it with popular alternatives:
| Parameter | Kixx PAO 5W-40 | Liqui Moly Top Tec 4200 | Mobil 1 ESP 5W-40 | Idemitsu Zepro Touring 5W-40 |
|---|---|---|---|---|
| Base | PAO + esters (5–7%) | PAO + hydrocracking | Hydrocracking + PAO | PAO (Japan) |
| HTHS, mPa s | 3.7 | 3.9 | 3.8 | 3.6 |
| Price for 4 l, ₽ | ~2 800 | ~4 200 | ~3 500 | ~3 100 |
| Nissan Approval | Strong Save X | Missing | Missing | Yes (Japan) |
Based on test results (for example, from the channel "Simply about the complex" on YouTube), Kixx PAO shows the best results for viscosity stability after 10 thousand km compared to Mobil 1 ESP, but inferior Liqui Moly Top Tec 4200 in cleaning properties. However, for engines Nissan with the system Eco Mode (For example, Qashqai 1.6 DIG-T) it is preferable Kixx thanks to a lower coefficient of friction.
When is it more profitable to choose an analogue?
- 🔧 For engines with direct injection (For example, MR16DDT in Juke) would be better suited Liqui Moly Top Tec 4200 due to better protection against soot.
- 🔧 In regions with extremely low temperatures (below -35°C) it is worth considering Idemitsu Zepro 0W-30.
- 🔧 For diesel Nissan (For example, Navara with YD25) is optimal Mobil Delvac MX 5W-40.
Kixx PAO 5W-40 is the best price/quality balance for Nissan gasoline engines with a mileage of up to 150 thousand km. For turbo engines and diesel engines, it is better to choose specialized oils.
Real reviews from Nissan owners: pros and cons
Analysis of reviews on forums (Drive2, Nissan-Club.ru) and on social networks shows that opinions about Kixx PAO 5W-40 are separated. Here are the key observations:
Pros (according to owners):
- ✅ Quiet start in winter — even at -30°C the oil does not thicken, the starter turns easily.
- ✅ Clean engine — after 10 thousand kilometers, soot on the valves is minimal (compared to semi-synthetics).
- ✅ Economical — waste consumption does not exceed 100–150 ml per 10 thousand km (for Qashqai 2.0).
- ✅ Price - cheaper than European analogues with comparable quality.
Cons and complaints:
- ❌ Fakes — there are a lot of counterfeit products on the market (especially in canisters without holograms).
- ❌ Not suitable for older engines - for some Nissan Primera P12 “oil starvation” appeared due to low viscosity at high speeds.
- ❌ Foams when driving aggressively - seen on Juke 1.6 Turbo with frequent accelerations.
⚠️ Attention: If after changing the oil to Kixx PAO 5W-40 did you notice increased fuel consumption (more than 1 liter per 100 km), this may indicate incompatibility with the system VVEL in engines Nissan (For example, VQ37VHR). In this case, the engine must be flushed and replaced with approved oil. Nissan KE909-99945.
On Drive2 user with nickname "Qashqai_J11" published the results of an oil analysis after 12 thousand kilometers: the iron content was 18 ppm (the norm is up to 30), and the viscosity remained within 5W-40. This confirms the stated stability of the product. However, another owner X-Trail T32 complained about loss of power after switching from Castrol Edge 5W-40 — the problem disappeared after returning to the previous oil.
Instructions for changing oil in Nissan: step-by-step algorithm
If you decide to fill Kixx PAO 5W-40 to your Nissan, follow this algorithm. Important: The procedure may differ for different models (for example, in Qashqai And Patrol different drain plugs).
Required tools and materials:
☑️ Preparing for an oil change
Step by step process:
- Turn off the engine and wait 5–10 minutes (the oil should drain into the pan, but not cool completely).
- Raise the car on a lift or use a jack (chock the wheels!).
- Unscrew the drain plug (on Qashqai J11 it is located to the right of the pan) and drain the waste.
- Replace the oil filter. In some models (for example, X-Trail T32) a special puller is required.
- Tighten the plug with a new gasket (tightening torque - 35–40 Nm).
- Fill in new oil through the filler neck (see table below for volume).
- Start the engine, let it run for 1-2 minutes, then check the level on the dipstick.
| Model Nissan | Engine | Oil volume, l | Replacement frequency, km |
|---|---|---|---|
| Qashqai J11 | MR20DE (2.0) | 4.4 | 15,000 (or 1 year) |
| X-Trail T32 | QR25DE (2.5) | 4.8 | 10,000 (under severe conditions) |
| Juke F15 | MR16DDT (1.6 Turbo) | 4.3 | 10 000 |
| Navara D40 | YD25DDTi (2.5 dCi) | 7.4 | 10 000 |
⚠️ Attention: If you are exploiting Nissan in conditions dusty roads or frequent traffic jams, reduce the replacement interval to 8–10 thousand km. Kixx PAO 5W-40 loses alkaline properties faster under high loads.
Common mistakes when using Kixx PAO 5W-40
Even experienced car owners sometimes make mistakes that reduce engine life. Here are the most common:
- 🚫 Mixing with other oils - even if both oils are 5W-40, different bases (PAO + hydrocracking) can react. For example, a mixture Kixx PAO And Shell Helix HX8 leads to the formation of sediment.
- 🚫 Exceeding the replacement interval — despite the declared durability, in Russian conditions the oil rarely “nurses” more than 12 thousand km.
- 🚫 Ignoring flushing - when switching from mineral or semi-synthetic oil to Kixx PAO be sure to use flushing oil (e.g. Liqui Moly Pro-Line).
- 🚫 Wrong filter - non-original filters (for example, from Framm) may not retain particles smaller than 20 microns, which is critical for Kixx PAO with its thin oil film.
Particularly dangerous pour oil without taking into account climatic conditions. For example, in Nissan Murano Z51 with engine VQ35DE when using Kixx PAO 5W-40 in hot weather (+40°C) may occur oil pressure drop at high speeds. In such cases, it is better to choose an oil with a viscosity 10W-40 or 5W-50.
What to do if the oil turns dark after 1 thousand km?
Darkening of the oil after an oil change is normal unless it is accompanied by metal shavings on the dipstick or increased consumption. Kixx PAO 5W-40 contains a high content of detergent additives that actively remove deposits, which leads to color changes.
FAQ: answers to popular questions
Is it possible to use Kixx PAO 5W-40 in a Nissan with more than 200 thousand km?
This oil is for high mileage engines. not recommended due to low high temperature viscosity (HTHS = 3.7). Optimal choice - Kixx G1 10W-40 or Lukoil Luxe 5W-40 with HTHS ≥ 3.9. An exception is if the engine is in perfect condition (compression in all cylinders is at least 12 bar).
Is this oil suitable for Nissan with LPG?
Yes, but with reservations. Kixx PAO 5W-40 has a base number (TBN) of 10.8, which is sufficient to neutralize acids formed during gas combustion. However, the replacement interval should be reduced to 8–10 thousand km, since HBO accelerates oil oxidation. Also check the level every 1-2 thousand km - gas increases waste.
How to distinguish original Kixx oil from a fake?
Signs of the original:
- 🔍 Canister with hologram on the lid (changes color when tilted).
- 🔍The production date is marked laser (not paint).
- 🔍 Engraved on the bottom of the canister serial number.
- 🔍 The price below 2,500 ₽ for 4 liters is a reason for suspicion.
Counterfeits often have a thinner consistency and a strong chemical smell.
Which is better for Nissan Qashqai 1.6 DIG-T: Kixx PAO 5W-40 or Idemitsu Zepro Touring 5W-40?
For turbocharged engine MR16DDT preferable Idemitsu Zepro Touring for two reasons:
- Higher alkalinity number (11.2 versus 10.8), which is important for neutralizing combustion products during turbocharging.
- Better thermal-oxidative stability (according to tests OilClub), which is critical for high temperatures in the turbine.
However Kixx PAO cheaper and suitable for a relaxed driving style.
Is it possible to drive Kixx PAO 5W-40 all year round in Russia?
Yes, if the temperature in your area does not drop below -35°C and doesn't rise higher +40°C. In Yakutia or the south of the Krasnodar Territory, it is better to choose specialized oils:
- 🥶 For the cold: Kixx PAO 0W-40 or Ravenol SSV 0W-30.
- ☀️ For the heat: Motul 8100 X-Clean 5W-40 (HTHS = 4.1).
