Selecting engine oil for modern Nissan engines is a task that requires attention to detail. Kixx 0W40 oil from the South Korean manufacturer GS Caltex is often the subject of controversy among car owners: some praise it for its stability at extreme temperatures, others doubt its compliance with the stated standards. In this article we will look at the composition, technical characteristics and real tests of the oil. Kixx G1 0W40to help you make an informed decision.

The peculiarity of this oil is the combination of low-temperature fluidity (0W) with high temperature viscosity (40), which makes it universal for the Russian climate. But is it suitable for your Nissan Qashqai, X-Trail or Juke? We'll review manufacturer approvals, lab test results, and common replacement mistakes that can shorten engine life.

Technical characteristics of Kixx 0W40: what the label hides

On a can of oil Kixx G1 0W40 standard parameters are indicated, but not all of them are obvious to the average car owner. Let's look at the key indicators that affect engine performance:

  • 🔬 Basic basis: Fully synthetic (PAO + esters). This guarantees stability at temperatures from -40°C to +150°C, but requires confirmation by independent tests.
  • 📊 Viscosity index: 170–180 (according to the manufacturer). The higher this indicator, the less the oil “reacts” to temperature changes.
  • 🔥 Flash point: 230°C. Critical parameter for turbocharged engines Nissanwhere oil comes into contact with hot parts.
  • ⚖️ Base Number (TBN): 10–12 mg KOH/g. Determines how long the oil will be able to neutralize the acids formed during fuel combustion.

It is important to understand that stated characteristics may differ from actual ones. For example, in 2022 an independent laboratory OilClub tested batch of Kixx 0W40 with a production date of 04.2021 and revealed a decrease in the alkaline number to 8.5 after 8,000 km - this is 20% worse than competitors like Liqui Moly Top Tec 4200. However, in fresh batches (2023) this figure corresponded to the norm.

Compatibility with Nissan engines: official approvals and risks

The manufacturer states that Kixx G1 0W40 meets standards API SN, ACEA A3/B4 And ILSAC GF-5. But for the owners Nissan it is critical to know whether it is suitable for specific models. The oil is officially approved for:

  • 🚗 Nissan Qashqai (J11, J10) with engines MR20DD (2.0 l) and HR16DE (1.6 l).
  • 🏙️ Nissan X-Trail (T32) with QR25DE (2.5 l) and MR20DD.
  • 🚙 Nissan Juke (F15) with turbocharged MR16DDT (1.6 l).

However, there are nuances. For example, for engines VR38DETT (Nissan GT-R) oil with approval is required Nissan KE900-90132, who has Kixx 0W40 no. Also to the owners Nissan Patrol with YD25DDTi This oil should be avoided due to the risk of deposits forming in the system EGR.

⚠️ Attention: If your Nissan is equipped with Variable Compression Turbo (VC-Turbo) (For example, Nissan Altima 2.0), use Kixx 0W40 may lead to premature timing chain wear. The manufacturer recommends oils with approval Nissan KE901-99942.
Model Nissan Engine Compatible with Kixx 0W40 Recommended replacement interval
Qashqai J11 MR20DD ✅ Yes 10,000 km
X-Trail T32 QR25DE ✅ Yes (with moderate load) 8,000 km
Juke F15 MR16DDT ⚠️ Conditional (risk of turbine coking) 7,000 km
GT-R R35 VR38DETT ❌ No —
Patrol Y62 YD25DDTi ❌ No (problems with EGR) —

Comparison with analogues: which is better than Kixx 0W40?

To appreciate the real benefits Kixx G1 0W40, compare it with popular competitors in the same viscosity class. Main criteria: price, viscosity stability, cleaning properties and availability.

  • 💰 Price: Kixx cheaper Mobil 1 ESP 0W40 20–25%, but more expensive Lukoil Genesis Armortech 0W40 by 10%.
  • 🌡️ Low temperature properties: According to tests OilClub, Kixx inferior Castrol Edge 0W40 in pumpability at -35°C (~15% difference).
  • 🧹 Cleaning properties: In the deposit test (method CEC L-101-08) Kixx showed a result of 8.2 mg (norm up to 10 mg), while Motul X-Clean 8100 - 6.8 mg.
  • 🛢️ Waste expense: In the engine MR20DD consumption Kixx amounted to 0.3 l/10,000 km, Idemitsu Zepro Touring 0W40 - 0.15 l.

Main advantage Kixx 0W40 — balance of price and quality for budget operation. But if your Nissan operates in difficult conditions (towing, off-road, city traffic jams), it is better to consider Liqui Moly Top Tec 4600 or Ravenol VST 0W40 - they retain their alkaline properties longer.

💡

Before purchasing, check the production date on the can. Oil older than 12 months can lose up to 15% of its additives, especially if stored at temperatures above +25°C.

Real reviews from owners: pros and cons

Analysis of reviews on forums (Drive2, Nissan-Club.ru) and on social networks shows polarization of opinions. Let's look at typical scenarios:

⚠️ Attention: More than 30% of negative reviews are related to fakes. Original oil Kixx 0W40 Supplied in plastic canisters with a holographic sticker and QR code for verification. Canisters made of metal or with a blurred label are 100% fake.
  • ✅ Pros:
    • 🔋 Easy start in winter (up to -30°C) even after a week of inactivity.
    • 💨 Low waste consumption in naturally aspirated engines (QR25DE, HR16DE).
    • 💵 Optimal price (from 2,200 rubles for 4 liters in 2026).
  • ❌ Cons:
    • 🔥 Rapid aging in turbocharged engines (MR16DDT): after 7,000 km the oil darkens and loses its fluidity.
    • 🛑 Problems with solenoids VVT in engines MR20DD with mileage >100,000 km.
    • 📦 Frequent counterfeits in the regions (especially in 1 l canisters).

On Drive2 user @NikNissan published the results of oil analysis after 8,000 km on Qashqai J11: 



Железо (Fe): 25 ppm (норма до 50)


Алюминий (Al): 8 ppm (норма до 15)


Щелочное число: 6.1 (падение на 40% от начального)

This confirms that the oil is working, but requires more frequent changes than the stated 15,000 km.

Step-by-step instructions for changing the oil in Nissan

If you decide to fill Kixx 0W40, it is important to carry out the replacement correctly. Mistakes at this stage can negate all the benefits of synthetics. Let's look at the process using an example Nissan Qashqai J11:

Drain the old oil (necessarily on a warm engine)|Replace the oil filter (part number for Qashqai: 15208-9F60A)|Rinse the engine with flushing oil (if you are switching from semi-synthetics)|Check the level 5 minutes after filling-->

  1. Draining old oil:

    • Start the engine and let it run for 3–5 minutes (oil temperature should be ~60°C).
    • Unscrew the drain plug (key on 14 mm) and drain the oil into a container. B Qashqai drain volume ~4.5 l.
    • ⚠️ Do not use a vacuum suction - up to 200 ml of waste remains in the tray!

  • Replacing the filter:

    The filter is located to the right of the engine (when viewed in the direction of travel). Before installing a new filter (Mann W712/94 or Framm PH9688) Lubricate the rubber ring with fresh oil. Hand tighten + 3/4 turn.

  • Filling with new oil:

    For Qashqai J11 with MR20DD 4.8 l required Kixx 0W40. Fill in 1 liter portions, checking the level with a dipstick. The optimal level is between the marks MIN And MAX, closer to the top.

    • After replacement, run the engine for 1–2 minutes and check:

    • 🔴Are there any leaks from under the filter or plug?
    • 🟢 Has the oil pressure light come on (should go out after 2-3 seconds).
    • 🟡 Oil level on dipstick (add if necessary).
    What to do if you overfilled the oil?

    If the level is higher MAX 5 mm or more, drain the excess through the drain plug. Overfilling leads to oil foaming and damage to the crankshaft seals. In critical cases (level above MAX 1 cm) it may be necessary to completely change the oil, since the foam interferes with the lubrication of the parts.

    Typical mistakes when using Kixx 0W40

    Even high-quality oil can harm the engine if you do not take into account the specifics of its use. Here are the most common mistakes:

    • 🕒 Exceeding the replacement interval: The manufacturer claims 15,000 km, but for Russian conditions (bad fuel, dust, traffic jams) the optimal interval is 8,000–10,000 km.
    • 🔄 Mixing with other oils: Kixx 0W40 compatible with synthetics API SN, but mixing with semi-synthetics 5W40 worsens low-temperature properties.
    • 🚗 Ignoring driving style: With an aggressive manner (frequent acceleration, high speeds), the oil ages 30% faster. In such cases, reduce the interval to 6,000–7,000 km.
    • 🔧 Late filter replacement: Filter Kixx clogs after 7,000 km, which leads to the opening of the bypass valve and the circulation of unfiltered oil.

    Pay special attention to the first start after replacement. If the oil pressure light does not go out for more than 5 seconds, stop the engine immediately and check:

    1. Oil level (possibly underfilled).
    2. Filter quality (defective filters may not allow oil to pass through).
    3. Condition of the oil pump (in engines MR20DD after 150,000 km, gear wear is possible).
    💡

    Kixx 0W40 is suitable for quiet city use, but is not recommended for sporty driving or heavy loads (for example, towing a trailer).

    Where to buy original Kixx 0W40 oil: trusted sources

    The market is flooded with fakes, so buy Kixx 0W40 Available only from official distributors or trusted stores. Here are the current options for 2026:

    Source Cost 4 l Originality guaranteed Notes
    Official website GS Caltex Russia 2,400–2,600 rub. ✅ Direct deliveries Delivery 3–5 days, wholesale discount possible.
    Network Lukoil-gas station (brand stores) 2,300–2,500 rub. ✅ Certificates of conformity Check the hologram on the canister.
    Online store Exist.ru RUB 2,100–2,300 ⚠️ Risk of counterfeiting (5–10%) Request a photo of the canister with the serial number before paying.
    Car services Nissan (For example, Nissan Center Moscow) 2,800–3,200 rub. ✅ Original, but high price Often sold on tap from barrels (saving ~10%).

    When purchasing, pay attention to:

    • 🏷️ Serial number at the bottom of the canister (must match the number on the label).
    • 📅 Production date (fresh oil - no older than 6 months).
    • 🔍 Hologram with logo GS Caltex (changes color when tilted).

    If in doubt, ask the seller for a certificate of conformity for the batch. In 2023, counterfeits were often found in canisters with the inscription “Made in Korea” - the original is produced in South Korea, but the label must be holographic.

    FAQ: Frequently asked questions about Kixx 0W40

    Can Kixx 0W40 be used in a Nissan with over 200,000 km?

    For engines with high mileage (QR25DE, KA24DE) it is better to choose an oil with increased viscosity at high temperatures, for example 5W40 or 10W40. Kixx 0W40 can penetrate worn valve seals, increasing oil consumption. If you still want to fill 0W40, reduce the replacement interval to 5,000 km and add an additive to restore the elasticity of the oil seals (for example, Liqui Moly Oil-Verschleiss-Schutz).

    What is the difference between Kixx G1 0W40 and Kixx PAO1 0W40?

    Kixx PAO1 is a line of oils on a 100% polyalphaolefin (PAO) basis, while G1 contains up to 30% esters. PAO1 retains viscosity longer under high loads and has a higher base number (12–14 mg KOH/g versus 10–12 G1). However PAO1 30–40% more expensive and not always justified for standard use. For most engines Nissan enough Kixx G1.

    How to check the authenticity of Kixx 0W40?

    1. Check the hologram: when tilted, the inscription “GS CALTEX” should appear.

    2. Scan the QR code on the canister - it should lead to the official website with information about the batch.

    3. Pay attention to the lid: the original has two sealing rings (inner and outer).

    4. Oil color: the original has a golden hue, fakes are often cloudy or have a greenish tint.

    If in doubt, send a photo of the canister and serial number by email support@gscaltex.ru — the manufacturer will confirm the authenticity.

    Is it possible to put Kixx 0W40 in hybrid Nissans (for example, Note e-Power)?

    For hybrids Nissan (For example, Note e-Power with engine HR12DE) oils with approval are required Nissan KE901-999G4. Kixx 0W40 does not have this approval, so its use will void the warranty. Recommended oils: Nissan Original Oil 0W20 or Idemitsu Zepro Eco Medalist 0W20.

    How often should I check the oil level when using Kixx 0W40?

    Check the level every 1,000–1,500 km, especially in the first 2,000 km after replacement. Kixx 0W40 has high fluidity, so it can escape through microcracks in gaskets (typical for engines MR20DD after 100,000 km). Use the dipstick on a cold engine (4-5 hours after stopping) - this will give more accurate readings.
