Technical characteristics of Kixx 5W-40 oil: analysis according to standards
Oil Kixx G1 5W-40 (the most common line) belongs to the category semi-synthetic lubricants with improved additives. Its base is a mixture of mineral and synthetic components (about 30–40% synthetics), which allows you to reduce the cost without a critical loss of properties. Here are the key parameters to consider when choosing:
- 🔹 SAE viscosity grade:
5W-40- Suitable for use at temperatures from -30°C to +40°C (actual range may become narrower under heavy loads). - 🔹 API Specifications:
SN/CF— meets the requirements for modern gasoline (including turbo) and diesel engines without particulate filters. - 🔹 Manufacturer approvals: Officially approved for Hyundai/Kia (but not for all models!), Renault, Nissan (except for engines with a system
EcoBoost). - 🔹 High Temperature Viscosity Index (HTHS): 3.5 mPa s - guarantees a stable oil film when heated to 150°C.
It is important to understand that Kixx 5W-40 is not full synthetic oil, despite the marketing tricks of some sellers. Its average resource is 8–10 thousand km with moderate use (in a city with traffic jams, the interval is reduced to 6–7 thousand km). For comparison: class synthetics 5W-40 from Castrol or Shell lasts 20–30% longer.
⚠️ Attention: Oil Kixx 5W-40 not suitable for engines with Start-Stop and hybrid installations. Its additive package is not optimized for frequent cold starts and may lead to accelerated oxidation.

Car compatibility: what engines is Kixx 5W-40 suitable for?
The manufacturer claims wide oil compatibility Kixx 5W-40, but in practice there are nuances. For example, it not recommended for engines with direct fuel injection (GDI/FSI) due to the risk of deposits forming on the valves. Let's take a closer look:
- 🚗 Japanese cars: suitable for Toyota (series
1ZZ-FE,3S-FE), Nissan (QR25DE,MR20DE), Mitsubishi (4G63,4G94). Doesn't fit for Subaru with boxer engines - requires oil with approvalSN Plus. - 🚗 Korean cars: optimal for Hyundai Solaris (engines
Gamma 1.4/1.6), Kia Rio, SsangYong Actyon. For turbocharged engines (Theta II) better to choose Kixx Turbo 5W-40 with improved cleaning properties. - 🚗 European cars: allowed for Renault Logan/Duster (engines
K4M/K7M), but prohibited for Volkswagen with standardsEuro-6(requiredVW 502.00/505.00).
For cars with mileage over 150 thousand km Kixx 5W-40 may not be the best choice due to low base number (9.8 mg KOH/g). In such cases, it is advisable to use oil with TBN ≥ 11, for example, Lukoil Luxe 5W-40 or Rosneft Maximum 5W-40.
Why is Kixx 5W-40 not suitable for engines with a diesel particulate filter (DPF)?
The oil contains sulfur and phosphorus in concentrations exceeding system tolerances DPF (for example, standard C3 according to ACEA). These elements poison the catalyst, reducing its life by 30–50%. Diesel engines with particulate filters require low SAPS oils (Low Ash), such as Kixx PAO1 5W-30 or Total Quartz INEO ECS.
Differences between Kixx G1, Turbo and PAO1: which oil to choose
Brand Kixx offers several lines of oils with viscosity 5W-40, and their properties are very different. Let's look at the key differences:
| Ruler | Base type | Base Number (TBN) | Recommended replacement interval, km | Price for 4l, ₽ |
|---|---|---|---|---|
| Kixx G1 5W-40 | Semi-synthetics | 9.8 | 7–8 thousand | 1 800–2 200 |
| Kixx Turbo 5W-40 | Semi-synthetics + enhanced additives | 10.5 | 8–10 thousand | 2 300–2 700 |
| Kixx PAO1 5W-40 | Full synthetic (PAO) | 12.1 | 12–15 thousand | 3 500–4 000 |
For most budget cars (eg. Lada Vesta or Renault Sandero) enough Kixx G1. If you have a turbocharged engine (Ford EcoBoost, VW TSI), it is better to give preference Kixx Turbo — it contains additional antioxidant additives. PAO1 justified only for sports or forced engines, where maximum thermal stability is required.
When switching from mineral oil to Kixx 5W-40 It is recommended to shorten the first replacement interval to 5 thousand km. This is due to the active flushing effect of the additives, which can flush out deposits and clog oil passages.
How to distinguish original Kixx 5W-40 oil from a fake
Fakes Kixx found in 20–25% of cases when purchased at non-certified points (markets, small stores). Main signs of counterfeit:
- 🔍 Canister lid: the original has it
3 lugsfor fixation and logo GS Caltex pressed font (for a fake - smooth or with rough engraving). - 🔍 Label: inscription on the original
Made in South Koreawritten in a clear font without blurring. Counterfeits are often printed on a printer (stripes are visible). - 🔍 Code at the bottom: in the original canister it is laser-applied and consists of
12 characters(letters + numbers). Counterfeits use stickers or paint. - 🔍 Oil color: the original has a golden-amber hue, fakes are cloudy or too dark (they add cheap additives).
Check by code on the site GS Caltex Russia takes no more than a minute. Enter 12 digit code from the bottom of the canister - the system will show the production date and batch. If the code is not recognized, you are faced with a guaranteed fake.
⚠️ Attention: Fake oil Kixx 5W-40 often diluted with a mineral base, which leads to coking of rings already in3–4 thousand km. First signs: increased oil consumption (more500 ml per 1,000 km) and black carbon deposits on the spark plugs.

Instructions for changing Kixx 5W-40 oil: step-by-step algorithm
Changing engine oil using Kixx 5W-40 has no specific features, but there are several important points:
- Warm up the engine up to operating temperature (
80–90°C), but do not turn it off - the oil drains faster when hot. - Drain the old oil through the plug in the pan (draining time - no less than
10 minutes). For Kixx 5W-40 it is critical to remove the maximum amount of waste, since it mixes with the new portion worse than synthetics. - Replace the oil filter. For Kixx filters with a high-density paper element are recommended (for example, Mann W 914/2 or Bosch 0 451 103 336).
- Fill with new oil in portions of
200–300 ml, checking the level with a dipstick. The optimal level is between the marksMINAndMAX, closer to the top.
After replacement, start the engine at 5 minutes at idle, then check the level again. If it falls below the middle of the dipstick, add 100–150 ml. Kixx 5W-40 has high fluidity, so the first 100–200 km After replacement, a slight drop in level is possible.
What should I do if the pressure indicator lights up after changing the oil?
1. Check the oil level - it may not be enough (add to the mark MAX).
2. Make sure the oil filter is installed correctly (the rubber ring must be lubricated).
3. If the lamp flashes after warming up, the oil pump or oil receiver screen may be clogged. In this case, diagnostics is required.

FAQ: Frequently asked questions about Kixx 5W-40 oil
Can Kixx 5W-40 be mixed with other oils?
Mixing is allowed only in emergency cases (for example, in case of a leak on the road) and only with oils of the same class API SN/CF and viscosity 5W-40. After this it is recommended complete oil change with engine flushing. Prolonged use of the mixture leads to sedimentation and clogging of oil channels.
Is Kixx 5W-40 suitable for engines with natural gas equipment (LPG)?
No, gas engines require oil with a high base number (TBN ≥ 12) and special additives against dry friction. Kixx 5W-40 does not meet these requirements - its use will lead to accelerated wear of valves and piston rings. Recommended Alternatives: Liqui Moly Leichtlauf High Tech 5W-40 or Mobil 1 ESP 5W-30.
How often should Kixx 5W-40 be changed in the urban cycle?
In urban operating conditions (frequent traffic jams, short trips), the replacement interval should be reduced to 6–7 thousand km. This is due to:
- 🔸 Accumulation of products of incomplete combustion of fuel (due to low quality gasoline).
- 🔸 Increased load on the oil with frequent starts of a cold engine.
- 🔸 Risk of sludge formation in the crankcase.
If the car is driven primarily on the highway, the interval can be increased to 9–10 thousand km.
Which is better: Kixx 5W-40 or 10W-40 for an old engine?
For engines with mileage over 200 thousand km and noticeable wear (increased oil consumption, knocking noises) is preferable 10W-40. It has a higher viscosity at operating temperatures, which compensates for the increased clearances. However Kixx 5W-40 better suited for modern engines (even with mileage), as it provides:
- 🔸 Easier start in winter.
- 🔸 Reduced mechanical losses (fuel savings up to
2–3%).
If the engine "eats" oil (> 1 l per 1,000 km), the problem is not in viscosity, but in wear of the rings or valve stem seals - repair is required.
Can Kixx 5W-40 be used in a transmission?
No, Kixx 5W-40 - this is motor oil, and its properties do not meet the requirements for transmission fluids. Manual transmission requires class oils GL-4/GL-5 (For example, Castrol Syntrans Transaxle 75W-90), and for automatic transmissions - specialized fluids (ATF). Using engine oil in the box will lead to:
- 🔸 Accelerated wear of synchronizers.
- 🔸 Foaming and loss of lubricating properties.
- 🔸 Difficulty shifting gears.
