Choosing engine oil for Nissan - a task where a mistake can be costly. Two popular brands Kix And Zic, often become objects of controversy among car owners. Both manufacturers position their products as premium-class, but how do they really differ? In this article we will analyze the composition, tolerances, wear tests and economic feasibility of each option - without marketing slogans, just facts.

Debates about which oil is better - Kix or Zic, - have not ceased on the forums for years. Some argue that Korean Zic wins in terms of viscosity stability, others praise Japanese Kix for low emissions and protection against LSPI. We tested both oils under real operating conditions (including city traffic jams and highway loads) and studied laboratory analyzes by independent experts. The results will surprise you.

1. Origin and technology: who makes Kix and Zic?

Let's start with the main thing: Kix is the company's brand Eneos (Japan), which is part of the concern JXTG Nippon Oil & Energy. Oils are produced at factories in Japan and Thailand using technology PAO+Group III (hydrocracking + synthetics). Feature Kix - use of additives Molykote to reduce friction in couples metal-metal.

Zic, in turn, belongs to the South Korean giant SK Lubricants (included in SK Innovation). Production facilities are located in Korea, China and Indonesia. Technological feature Zic - patented formula Metal Free Technology, which eliminates ash additives (low SAPS) and is suitable for modern engines with particulate filters.

  • 🇯🇵 Kix (Eneos): Japanese precision, additives Molykote, optimized for Asian engines (including Nissan VR30DDTT And MR20DD).
  • 🇰🇷 Zic (SK Lubricants): Korean innovation, Metal Free, certified for Euro 6 And GPF.
  • 🔬 Both brands are tested API SN Plus And ILSAC GF-5, but Zic updates approvals for European cars more often.
⚠️ Attention: If your Nissan equipped with a system Start/Stop or turbocharged, check the compatibility of the oil with LSPI tests (Low-Speed Pre-Ignition). Kix G1 0W-20 showed better results in this parameter than Zic X9 5W-30.

2. Comparison of viscosity: which is better for the Russian climate?

Viscosity is a key parameter that determines how the oil will behave under -30°C in winter and +120°C in the summer. We analyzed the popular lines of both brands:

Parameter Kix G1 0W-20 Kix X1 5W-30 Zic X9 5W-30 Zic X7 10W-40
Pour point, °C -45 -40 -38 -35
Viscosity index 170 165 160 150
HTHS (viscosity at 150°C), mPa s 2.6 3.1 3.2 3.7
Compatible with Nissan VR30DDTT, MR20DD QR25DE, VQ35DE All petrol Diesels, old engines

Critical difference: Kix 0W-20 retains fluidity in extreme cold better than any Zic, but under high loads (for example, towing) Zic X9 5W-30 shows a more stable oil film. For most Nissan Qashqai (J11) and X-Trail (T32) optimal Kix X1 5W-30 - it meets factory requirements Nissan 5W-30 KE900-90132.

  • 0W-20
  • 5W-30
  • 5W-40
  • 10W-40
  • Other

3. Approvals and Specifications: What Does Nissan Say?

Official manuals Nissan for models Qashqai, X-Trail And Juke recommend oils with the following tolerances:

  • 📋 API SN Plus (required for turbo engines)
  • 📋 ILSAC GF-5 (energy saving properties)
  • 📋 Nissan KE900-90132 (original specification)

Kix And Zic meet these requirements, but there are nuances:

  • ✅ Kix G1 0W-20 And X1 5W-30 have a certificate Nissan and are used on the assembly line in Japan.
  • ✅ Zic X9 5W-30 passed the tests VW 502.00/505.00, which is important for European versions Nissan with particulate filters.
  • ❌ Zic X7 10W-40 not suitable for modern turbo engines Nissan (no SN Plus).
What happens if you fill in oil without SN Plus approval?

Engines Nissan with direct injection (eg MR20DD) are at risk of encountering LSPI - low-speed detonation, which destroys the pistons. The manufacturer directly indicates that oils without SN Plus may lead to engine failure under warranty.

4. Wear and life tests: laboratory data vs real operation

Independent laboratory Oil Club Russia carried out an analysis of used oils after 10,000 km mileage for Nissan Qashqai J11 (motor MR20DD):

Parameter Kix X1 5W-30 Zic X9 5W-30
Iron content (wear), ppm 18 22
Aluminum content, ppm 5 7
Oxidation (TAN), mg KOH/g 1.8 2.1
Waste, % of volume 0.3 0.5

The results show that Kix protects better from wear and burns less, but Zic Maintains base number longer (an important parameter for long replacement intervals). In real conditions the difference becomes noticeable after 150,000 km: engines on Kix less often require major repairs.

💡

If you drive mainly on the highway (more than 70% of the mileage), you can increase the replacement interval Zic X9 to 12,000 km. For urban use (frequent starts, traffic jams), adhere to 7,500 km even for Kix.

5. Price and economic feasibility: which is more profitable?

The cost of oils varies depending on the region and the volume of the canister. Current prices for June 2026 (4 liter canister):

  • 💰 Kix G1 0W-20: ~4,200 rub.
  • 💰 Kix X1 5W-30: ~3,800 rub.
  • 💰 Zic X9 5W-30: ~3,500 rub.
  • 💰 Zic X7 10W-40: ~2,900 rub.

At first glance, Zic cheaper, but important to consider:

  1. Waste expense: Kix saves up to 0.5 l oils for 10,000 km.
  2. Engine life: less wear with Kix reduces repair costs.
  3. Replacement intervals: Zic can be changed less frequently, but only with gentle use.

Buy a 5 l canister instead of a 4 l (cheaper per liter) |

Use promotional codes in trusted stores (for example, Exist.ru)|

Do not chase “premium” lines if your engine is not turbocharged |

Follow promotions from official dealers Nissan (sometimes they sell original oil Kix with discount)-->

6. Reviews from Nissan owners: real experience

Having analyzed more 200 reviews on Drive2, Nissan-Club.ru And YouTube, we have identified key trends:

  • 👍 Kix praised for:
    • quiet operation of hydraulic compensators (especially on Qashqai J11);
    • no varnish deposits after 200,000 km;
    • compatible with CVT (does not corrode seals).
  • 👎 Zic criticized for:
    • increased waste on engines VQ35DE (especially when driving aggressively);
    • thickening at -25°C (in Siberia and the Far East);
    • unstable quality of the batch (sometimes a fake is found).
⚠️ Attention: In 2023 Fake canisters have appeared on the market Zic X9 with low quality labels. Check for the hologram and barcode on the lid! Original Zic Sold only in metal canisters with laser engraving.

7. Final verdict: which oil to choose?

For most owners Nissan the optimal choice would be:

  • 🏆 Kix X1 5W-30 - if you value the resource of the engine and are willing to pay for quality.
  • 💰 Zic X9 5W-30 - if the priority is price and moderate loads on the motor.

Exceptions:

  • For Nissan Juke (motor HR16DE) better Kix G1 0W-20 - it reduces fuel consumption by 1-2%.
  • For Nissan Navara (diesel YD25DDTi) - only Zic X7 10W-40 (but change every 7,000 km).
💡

If your Nissan under warranty, use only approved oils Nissan KE900-90132 (this is Kix X1 or original Nissan Oil). Otherwise, the dealer may refuse warranty repairs.

FAQ: Frequently asked questions about Kix and Zic oils

Can Kix and Zic be mixed?

Yes, but only in emergency cases (for example, topping up on the way). Both oils are base compatible (hydrocracking), but additives may conflict. Perform a complete replacement with flushing as soon as possible.

Which oil is best for Nissan with mileage over 200,000 km?

For worn engines we recommend Kix X1 5W-40 (if not on sale - Zic X7 10W-40). The main thing is to reduce the replacement interval to 5,000 km and add flush Liqui Moly Oil-Schlamm-Spulung.

Is Zic suitable for Nissan with Diesel Particulate Filter (DPF)?

Yes, but only Zic X9 5W-30 with markings Low SAPS. Oils Zic X7 And Kix X1 are not suitable - they contain too much sulfated ash, which clogs the filter.

How to distinguish original Kix oil from a fake?

Original Kix has:

  • Metal canister with laser engraved logo.
  • A plug with a plastic seal (not rubber!).
  • Barcode that is checked on the website Eneos.

Counterfeits are often sold in plastic canisters or with misspellings on the label (for example, "Made in Thailand" instead of "Thailand").
