Oil Kix is a brand that over the past few years has been actively gaining popularity among car owners, especially those who are looking for a high-quality alternative to expensive original lubricants. The manufacturer positions its products as a fully synthetic oil with improved detergent and antioxidant properties, but how do these statements correspond to reality? In this article we have collected current reviews of Kix oil from owners of different car models, analyzed laboratory tests and compared it with competitors.
We will pay special attention to the issues that most often concern drivers: Compatible with Nissan engines (including Qashqai, X-Trail, Juke), real waste consumption, behavior at low temperatures and long-term effect on wear of parts. We’ll also figure out why some service station technicians refuse to fill Kix, despite its certificates, and where to buy original products so as not to run into fakes.
Composition and technical characteristics of Kix oil: what does the label hide?
The manufacturer states that the oil Kix manufactured on the basis completely synthetic base (PAO + esters) with a package of additives from well-known European suppliers. However, reviews often contain doubts: is this really top-level synthetics, or are we looking at semi-synthetics with marketing hype? Let's look at the key parameters:
- 🔬 Basic foundation: according to independent laboratories (including tests OilClub), the composition is dominated by hydrocracking components (HC synthetics), and not PAO, as stated. This does not make the oil bad, but it does call into question its belonging to the premium segment.
- ❄️ Temperature properties: viscosity index (VI) ranges from 160 to 170 units - a good indicator for all-season use, but not a record one. For example, at Motul 8100 VI reaches 180.
- 🛢️ Ash content: low ash (Low SAPS) - suitable for modern engines with diesel particulate filters (DPF) and catalysts.
- 🔥 Flash point: 220–230°C (for oils
5W-30And5W-40), which is lower than top brands (for example, Liqui Moly Top Tec 4200 has 236°C).
It's important to note that Kix certified according to standards API SN, ACEA C3 And C5, and also has approvals from Nissan, Toyota And Hyundai/Kia. However, in owner reviews Nissan Almera And Qashqai there are complaints about increased oil burn after switching from original Nissan Oil on Kix 5W-30. The reason may lie in the incomplete compatibility of additives with Japanese engines.
⚠️ Attention: If your car is under warranty, fill the oil Kix may result in denial of warranty service. Dealers Nissan And Renault often require the use of only original lubricants or oils from the official list (for example, Total Quartz for the alliance).
Owner reviews: real experience using Kix oil
Analysis of reviews on sites like Drive2, AutoMotoClub And Yandex.Market shows that opinions about oil Kix highly polar. We have identified key trends:
| Car model | Oil type | Pros (according to reviews) | Cons (according to reviews) |
|---|---|---|---|
| Nissan Qashqai J11 (1.6/2.0) | 5W-30, 5W-40 |
✅ Quiet engine operation, no leaks | ❌ Burnout ~300 ml per 10,000 km (at a norm of 100–150 ml) |
| Renault Duster (1.5 dCi) | 5W-40 |
✅ Good cold start at -30°C | ❌ Thickening after 8,000 km (according to oil analysis) |
| Toyota Corolla E210 (1.6) | 0W-20 |
✅ Fuel savings (~2% according to the on-board computer) | ❌ Noise of hydraulic compensators after 5,000 km |
| Kia Rio 4 (1.4) | 5W-30 |
✅ Low price, easy to find in stores | ❌ Counterfeits occur in 30% of cases (according to surveys) |
Interesting fact: among the owners Nissan X-Trail T32 with engine MR20DD oil Kix 5W-40 proved to be better than Qashqai. Perhaps it has to do with the design features of the oil system. At the same time, drivers Mitsubishi Outlander complain about formation of varnish deposits after 10,000 km, which is confirmed by photographs from endoscopic diagnostics.

Laboratory tests: what does Kix oil analysis hide?
Independent laboratories such as OilClub And Blackstone Labs, carried out several oil tests Kix after a run of 8,000–12,000 km. The results were mixed:
- 🧪 Metal content (wear): an increased amount was found in the used oil
iron (Fe)Andaluminum (Al), which speaks about accelerated wear of piston rings and liners. For example, in the test for Nissan Juke with engineHR16DEthe Fe content was 45 ppm (at a rate of up to 30 ppm for synthetics). - 🔥 Oxidation: parameter
TAN (Total Acid Number)after 10,000 km it increased to 3.2 mg KOH/g (the norm is up to 2.5). This indicates premature aging of oil. - 🛢️ Viscosity: viscosity at 100°C after 8,000 km dropped from 12.5 to 10.8 mm²/s (for
5W-40), which is close to the lower tolerance limit. Risk of oil starvation under high loads!
For comparison: oil Idemitsu Zepro 5W-30 under the same conditions showed Fe = 22 ppm, TAN = 1.8, and the viscosity remained within the range of 12.1–12.3 mm²/s. This confirms that Kix inferior to Japanese original oils in stability.
Oxidation Test Details
In the OilClub laboratory, Kix 5W-40 oil was tested for accelerated aging at a temperature of 150°C for 168 hours. The results showed that after 72 hours active sludge formation began (up to 0.4% by weight), while for Motul X-Clean a similar indicator appeared only after 120 hours.
⚠️ Attention: If you operate the car in taxi mode or often sit in traffic jams, the oil change interval Kix it is worth reducing to 7,000–8,000 km. With normal driving (highway/city 50/50), you can aim for 10,000 km, but no more.
Comparison with competitors: is it worth overpaying?
To understand how justified the savings are when choosing Kix, let’s compare it with popular analogues in the same price segment (5,000–7,000 rubles per 4 l):
| Parameter | Kix 5W-40 | Lukoil Luxe 5W-40 | Rosneft Magnum 5W-40 | Total Quartz 9000 5W-40 |
|---|---|---|---|---|
| Basic basis | Hydrocracking + esters (up to 10%) | Hydrocracking | Hydrocracking | PAO + esters (up to 20%) |
| Flash point, °C | 225 | 220 | 215 | 235 |
| Sulfur content, % | 0.21 | 0.25 | 0.30 | 0.18 |
| Price for 4 l, ₽ | 5 200 | 4 800 | 4 500 | 6 500 |
From the table it is clear that Kix occupies an intermediate position: it is better than budget Lukoil And Rosneft in terms of temperature properties, but loses Total Quartz on stability and sulfur content. If your budget is limited, Kix - a reasonable choice, but for turbocharged engines (for example, Nissan 1.6 DIG-T) better consider Total or Mobil 1.
Before purchasing Kix oil, check the batch on the manufacturer’s website using the QR code on the canister. Counterfeits often have typos in the label font (for example, the letter "K" in the word "Kix" may no longer be the original).
Where to buy and how to avoid counterfeiting?
One of the main risks when buying oil Kix - run into counterfeit goods. According to RNP "Avtomotosoyuz", up to 40% of canisters on the market are fakes, especially in small stores and markets. Here signs of original oil:
- 📦 Packing: the canister must be made of matte plastic with a clearly embossed logo Kix at the bottom. Fakes are often glossy.
- 🏷️ Label: hologram with a “shimmering” effect when tilted, the font is even, without blurring. On the reverse side is the bottling date (month/year).
- 🔍 Cover: The original has a protective ring with the inscription "SEALED FOR YOUR PROTECTION". On fakes, the ring is often missing or the inscription is misspelled.
- 📱 QR code: should lead to the official website
kixoil.ruwith information about the party. If the code cannot be scanned or leads to a third-party resource, it is a fake.
Best places to buy:
- Official dealers Kix (list on the manufacturer's website).
- Large chain stores: AutoSpetsCenter, existential, AutoAll.
- Online platforms with a guarantee of originality: Ozon (seller "Kix Official"), Wildberries (Kix Russia store).

Expert opinion: is it worth putting Kix into the engine?
We interviewed three independent auto mechanics with more than 10 years of experience. Their opinions were divided:
Alexey, service station foreman (Moscow):
"For budget foreign cars (for example, Renault Logan or Kia Rio) Kix — a normal option if you change it every 8,000 km. But in engines with direct injection (Nissan 1.3 DIG-T, Toyota 1.2T) I would not recommend - the risk of valve coking is high."
Igor, diagnostician (St. Petersburg):
"In my practice I have seen two cases when Kix 5W-30 led to piston rings on Nissan Note with a mileage of 120,000 km. The reason is low cleaning power. If the car is more than 10 years old, it is better to take oil with a high base number (TBN > 10)."
General conclusion of the experts: Kix suitable for:
- ✅ Atmospheric engines with a mileage of up to 150,000 km.
- ✅ Cars with a simple oil system design (for example, Lada Vesta, Hyundai Solaris).
- ✅ Regions with a temperate climate (from -25°C to +35°C).
Not recommended for:
- ❌ Turbocharged and hybrid engines.
- ❌ Cars under warranty (risk of service refusal).
- ❌ Extreme conditions (racing, off-road, taxi).
Kix oil is a compromise option for budget-conscious owners. It is no worse than budget analogues (Lukoil, Rosneft), but inferior to premium brands (Motul, Idemitsu) in terms of durability and wear protection.
FAQ: answers to frequently asked questions about Kix oil
Can Kix be mixed with other oils?
Mixing is allowed only in emergency cases (for example, leakage) and only with oils of the same standard (API SN, ACEA C3). After that necessarily Reduce replacement interval by 30%. It is optimal to add oil from the same manufacturer (for example, Kix 5W-30 + Kix 5W-40 in a 1:1 ratio).
Why did the knocking of the hydraulic compensators appear after replacing the Kix?
This problem is typical for engines Toyota And Nissan with mileage over 100,000 km. Reason - low viscosity at high temperatures (HTHS < 3.5 mPa s). Solution:
- Switch to higher HTHS oil (eg. Kix 5W-40 instead of
5W-30). - Flush the engine before replacing (use
Liqui Moly Pro-Line).
What is the optimal Kix oil change interval?
The manufacturer claims 15,000 km, but experts recommend:
- 🚗 Gasoline naturally aspirated engines: 10,000–12,000 km.
- ⚡ Turbocharged/diesel: 7,000–8,000 km.
- 🏙️ City mode (traffic jams): 6,000–7,000 km.
When using oil Kix 0W-20 in hybrids (for example, Toyota Prius) the interval is reduced to 5,000 km due to high loads on the oil.
Is Kix suitable for engines with diesel particulate filter (DPF)?
Yes, but only markings Low SAPS (For example, Kix Eco 5W-30 C2/C3). These oils have a reduced sulfated ash content (< 0.8%), phosphorus and sulfur. However for Nissan with the system Eco Mode it is better to choose original oil Nissan KE900-90132 — it is optimized for working with variable valve timing.
What should I do if my oil consumption increases after replacing it with Kix?
Possible causes and solutions:
| Reason | Solution |
|---|---|
| Low viscosity at high temperatures | Go to 5W-40 or 10W-40 (for older engines). |
| Wear of oil scraper rings | Use additive Liqui Moly Oil-Verschleiss-Schutz or do decoking. |
| Counterfeit oil | Drain the oil, flush the engine, refill with the original. |
