Selecting motor oil is a task that requires attention to detail. Even experienced car owners sometimes get lost among the variety of brands and specifications. ZIC oils from South Korean manufacturer SK Lubricants have gained popularity due to the optimal price-quality ratio, but how to choose the right ones according to the car brand? In this article we will look at all the nuances: from deciphering the markings to specific recommendations for different cars.

Many people mistakenly believe that it is enough to focus only on viscosity SAE (for example, 5W-30 or 10W-40). However, other parameters are also important for engine longevity: manufacturer tolerances (API SN, ACEA C3), type of base oil (mineral, semi-synthetic, synthetic), as well as special additives. ZIC series oils XQ LS and TOP contain unique detergent additives Low SAPSwhich are critical for modern turbocharged engines with particulate filters. Below you will find out how these parameters relate to the requirements of your vehicle.

It is equally important to take into account the climatic operating conditions. For example, for regions with frosts below -30°C, the optimal choice would be oils with the index 0W or 5W, while for the southern regions more viscous options are suitable. We have prepared compatibility tables and checklists that will help you avoid mistakes during selection.

Why ZIC: advantages and features of the brand

Brand ZIC belongs to the company SK Lubricants - one of the largest manufacturers of lubricants in Asia. Its products are delivered to conveyors Hyundai, Kia, Renault and other auto giants like primary filling. This indicates high trust on the part of manufacturers. Here are the key benefits of oils ZIC:

  • 🔬 Technology Yubase: unique high viscosity index base oils obtained by deep hydrotreating. This ensures stable properties even at extreme temperatures.
  • 🛡️ Wear protection: additive package ZDDP (zinc dialkyldithiophosphate) forms a durable film on parts, reducing friction by 20–30% compared to analogues.
  • 🌿 Eco-friendly: line ZIC XQ LS meets the standard Low SAPS (low content of sulfur, phosphorus and sulfated ash), which is critical for cars with catalysts and particulate filters.
  • 💰 Price/quality: based on test results ADAC (2023), oils ZIC show characteristics at the level of premium brands at a price 15–25% lower.

However, not all oils ZIC equally versatile. For example, a ruler ZIC A+ suitable for older carburetor engines, whereas ZIC X9 was developed specifically for modern turbo engines with direct injection. In order not to make a mistake, you need to clearly understand which series corresponds to your car.

Decoding the markings: what the letters and numbers mean

Oil marking ZIC contains several key elements that help define their properties. Let's look at an example ZIC X9 5W-30 API SN/GF-5:

  • ZIC X9 - name of the line. X9 indicates a premium, fully synthetic oil with improved cleaning properties.
  • 5W-30 — viscosity class according to SAE:
    • 5W — winter viscosity (the lower the number, the better the start in the cold).
    • 30 — summer viscosity (indicates the thickness of the oil at operating temperature).
  • API SN - classification according to standard American Petroleum Institute. SN - the most modern class for gasoline engines (for 2026). Classes are relevant for diesel engines CK-4 or FA-4.
  • GF-5 - specification ILSAC, indicating energy-saving properties and compatibility with exhaust gas aftertreatment systems.

Special attention should be paid to type designations LS (Low SAPS) or FE (Fuel Economy). The first ones are intended for cars with particulate filters (DPF), the second - to save fuel due to reduced viscosity. For example, ZIC XQ LS 5W-30 suitable for Volkswagen with engines TDI, whereas ZIC X9 FE 0W-20 optimal for hybrids Toyota Prius.

What is Low SAPS and why is it important?

Oils Low SAPS contain a minimum amount of sulfur, phosphorus and sulfate ash. These elements form deposits that clog diesel particulate filters (DPF) and catalysts. For example, in engines BMW N47 or Mercedes OM642 using conventional oil will lead to filter failure after 80–100 thousand km.

ZIC oil selection table by car make

Below is the oil compatibility table ZIC with popular car brands. Data based on manufacturers' recommendations and test results OEM-laboratories. Please note that for an accurate selection, it is necessary to take into account not only the brand, but also the model, year of manufacture, as well as the type of engine (gasoline/diesel, atmospheric/turbo).

Car make Recommended ZIC line Viscosity grade Manufacturer's approvals Features
Hyundai/Kia (2015–2026) ZIC X9 or ZIC TOP 5W-30, 5W-40 API SN, ILSAC GF-5 Motor Approved Gamma, Nu, Theta II. For hybrids - 0W-20.
Toyota (incl. Lexus) ZIC X9 FE or ZIC LV 0W-20, 5W-30 API SP, ILSAC GF-6 For engines with system Dual VVT-i low ash content is required (Low SAPS).
Volkswagen/Audi/Skoda (TDI) ZIC XQ LS 5W-30 VW 507.00, ACEA C3 Only for diesel engines with particulate filter (DPF). Not compatible with engines before 2005.
BMW/Mini (gasoline) ZIC X9 or ZIC TOP 0W-40, 5W-40 BMW LL-04, ACEA A3/B4 For engines N20, B48 Approved oil required LL-17 FE+ (use ZIC LV).
Lada/Renault/Nissan ZIC A+ or ZIC X7 5W-40, 10W-40 API SL/CF, RN0700/RN0710 For engines VAZ-21127 and K4M Semi-synthetic is suitable. For Nissan QR25DE - only synthetics.

⚠️ Attention: For cars with mileage over 150 thousand km, it is recommended to use oils with high viscosity (for example, 5W-40 instead of 5W-30), since engine wear requires a denser oil film. However, this rule does not apply to turbocharged engines - for them it is critical to comply with factory specifications.

Step-by-step instructions: how to choose ZIC oil for your car

To avoid errors, follow this algorithm:

  1. Determine engine type: petrol or diesel, naturally aspirated or turbocharged. For example, for Ford EcoBoost 1.6 you will need approved oil Ford WSS-M2C948-B, and for Mercedes OM611 — with MB 229.5.
  2. Check the instruction manual: Look for the "Recommended Oils" section (usually labeled as Engine Oil Specification). The tolerances are indicated there (API, ACEA, OEM).
  3. Consider climatic conditions:
    • For regions with frosts below -25°C: 0W-30 or 0W-40.
    • For temperate climates: 5W-30 or 5W-40.
    • For hot regions: 10W-40 or 15W-40 (only for older engines!).
  • Select ZIC line:

    Check presence of diesel particulate filter (DPF) → if present, select ZIC XQ LS|

    For hybrids or small volumes (up to 1.4 l) → ZIC LV 0W-20|

    For engines with mileage >150 thousand km → ZIC X9 5W-40|

    For old carburetor cars → ZIC A+ 15W-40-->

  • Check the compatibility chart (see section above) or use official ZIC picker.

    • ⚠️ Attention: If your car is equipped with a system Start-Stop (for example, Citroën C3 or Mazda Skyactiv), use oils with improved anti-wear properties, such as ZIC X9 FE+. These engines experience increased stress during frequent starts, and conventional “synthetics” may not provide sufficient protection.

    Common mistakes when choosing ZIC oil and how to avoid them

    Even experienced car owners sometimes make mistakes that reduce engine life. Here are the most common of them:

    • 🔧 Ignoring manufacturer's tolerances. For example, fill ZIC A+ instead of ZIC XQ LS in Volkswagen Passat B8 with engine 2.0 TDI will lead to clogging of the particulate filter after 50 thousand km.
    • 🌡️ Climate failure. Usage 10W-40 in Siberia in winter it is fraught with problems with starting and increased wear in the cold.
    • 🔄 Mixing different types of oils. Adding mineral oil to synthetics (or vice versa) leads to sedimentation and clogging of the oil channels.
    • ⏳ Exceeding the replacement interval. Even the highest quality oil loses its properties after 10–15 thousand km (or 1 year). For turbo engines, this interval is reduced to 7–10 thousand km.

    It is especially dangerous to skimp on oil for cars with turbocharging or direct injection (for example, Mitsubishi 4B11 or Ford EcoBoost). In such engines, the temperature and pressure are higher than in atmospheric ones, so oils with improved thermal-oxidative stability are required. ZIC X9 or ZIC TOP were just developed for such conditions.

    💡

    Check the authenticity of the oil before purchasing! On the official website ZIC There is a verification service using a QR code on the canister. Counterfeits are often found in lines X9 and TOP and may contain hazardous additives.

    Comparison of ZIC with analogues: which is better for your car

    To understand how much oil ZIC suit your car, compare them with popular analogues according to key parameters:

    Parameter ZIC X9 5W-30 Mobil 1 ESP 5W-30 Liqui Moly Top Tec 4200 Castrol Edge 5W-30
    Base oil Yubase (group III+) Synthetics (group III) PAO (group IV) Synthetics (group III)
    Viscosity index 170 165 180 168
    SAPS Contents Average Low (Low SAPS) Low Average
    Price for 4 l (2026) ~2 800 ₽ ~4 200 ₽ ~3 500 ₽ ~3 800 ₽
    Best choice for Universal solution for gasoline and diesel internal combustion engines Cars with particulate filters (DPF) Sports and turbocharged engines Motors with high loads (e.g. BMW N57)

    From the table it is clear that ZIC X9 loses Liqui Moly Top Tec 4200 according to the viscosity index, but wins in price. For most everyday vehicles (eg. Toyota Corolla or Hyundai Solar) the difference in characteristics will be unnoticeable, and the savings will be up to 20%. However, for premium cars (for example, Audi S5 or BMW M5) it is better to choose more expensive analogues with a PAO base.

    💡

    Oils ZIC optimal for cars in the mass segment (up to 2018) and Korean brands. For European premium cars older than 2020, it is better to consider specialized products (for example, Mobil 1 FS or Motul Specific).

    Where to buy ZIC oil: how to avoid fakes

    Counterfeit oils ZIC are more common than premium brands due to their high popularity and affordable price. Here's how to minimize risks:

    • 🛒 Official dealers: buy in branded stores SK Lubricants or from authorized partners (list on the website zicoil.com).
    • 📦 Packaging: original canisters have:
      • Holographic sticker with QR code (checked through the application ZIC Authenticity).
      • Production date and batch at the bottom of the canister (laser marked).
      • Stopper with a “skirt” (tamper-evident).
    • 💰 Price: if the cost is 30% or more below the market average, this is a reason to doubt. For example, ZIC X9 5W-30 cannot cost less than 2,500 ₽ for 4 liters.
    • 📄 Documents: Require a quality certificate (batch data must be included in it).

    ⚠️ Attention: Fake oils are often diluted with cheap mineral bases and aggressive additives are added that destroy oil seals and gaskets. For example, in 2023, several batches of counterfeit goods were identified in Russia. ZIC TOP, containing sulfur 3 times higher than normal. This led to corrosion of timing parts in engines Kia Rio and Hyundai Creta.

    If you doubt the authenticity, have the sample tested by an independent laboratory (e.g. Oil Club or Modeng). The cost of the analysis is about 1,500 rubles, but it is cheaper than engine repair.

    FAQ: answers to frequently asked questions

    Is it possible to use ZIC X9 in an engine with a mileage of 200 thousand km?

    For engines with mileage over 150 thousand km, it is recommended to switch to oils with high viscosity (for example, 5W-40 or 10W-40) and a high content of anti-wear additives. ZIC X9 5W-40 suitable, but it is better to choose specialized oils for “age” engines, such as ZIC RV or Liqui Moly Hochleistungs.

    ⚠️ Exception: if the engine “eats” oil (consumption >1 liter per 10 thousand km), then ZIC X9 may be too runny. In this case, temporarily use 15W-40 (for example, ZIC A+), but get ready for a major overhaul.

    What is the difference between ZIC TOP and ZIC X9?

    ZIC TOP is a semi-synthetic oil based on hydrocracking, while ZIC X9 - completely synthetic using technology Yubase. Main differences:

    • Thermal stability: X9 maintains viscosity up to +150°C, TOP - up to +130°C.
    • Replacement interval: X9 can be operated for up to 15 thousand km (under ideal conditions), TOP - up to 10 thousand km.
    • Price: X9 20–30% more expensive, but justified for turbo engines.

    For most naturally aspirated engines (eg Lada Vesta or Renault Logan) the difference will be insignificant, but for Ford Focus ST or Hyundai i30 N better to choose X9.

    Is ZIC suitable for cars with LPG?

    Yes, but with reservations. Gas engines (LPG/CNG) operate at higher temperatures, so the oil must have:

    • Increased thermal-oxidative stability (e.g. ZIC X9 or ZIC LV).
    • Improved cleaning properties (due to the absence of flushing additives in the gas).
    • More frequent replacement interval: every 7–8 thousand km instead of 10–15 thousand km.

    Do not use oils with energy saving properties (FE) - they are too liquid for HBO. Optimal choice: ZIC X9 5W-40 or ZIC TOP 10W-40 (for old cars).

    How to check the compatibility of ZIC oil with my car?

    The most reliable way is to use official ZIC picker. Alternative methods:

    1. Look at the tolerances in the instruction manual (section Lubricants or Maintenance).
    2. Compare them with the specification chart on the canister (e.g. VW 502.00 or MB 229.3).
    3. If there is no exact match, choose an oil with higher class (for example, API SP instead of API SN).

    For European cars (for example, Peugeot or Citroën) be sure to check the database TotalEnergies — there is a cross-comparison of tolerances.

    Can ZIC be mixed with other oils?

    Mixing is allowed only in emergency cases (for example, if there is an oil leak on the road) and subject to the following rules:

    • Only oils same type (synthetic with synthetic, semi-synthetic with semi-synthetic).
    • Same viscosity SAE (for example, 5W-30 with 5W-30).
    • Compatible tolerances (e.g. API SN can be mixed with API SP, but not with API SL).

    After mixing necessarily Change the oil and filter as soon as possible. For example, if you topped up ZIC X9 different oil, reduce the replacement interval to 5 thousand km.
