The introduction of car oils in the Svetofor range has caused a stir among motorists. The low price, often two to three times below the market value of well-known brands, makes you wonder what is behind the bright label. Drivers are looking for ways to save on car maintenance, and discount shelves seem like the perfect solution. But the engine is the heart of the car, and pouring an unknown substance into it is scary even with certificates.
Many drivers are wondering if they can be trusted. traffic-light oil There are battles going on in forums, where some people swear they're pouring it for the third time without any problems, and others predict a major overhaul after the first thousand kilometers, and the reality, as it often happens, is in the middle, and it requires a detailed analysis of the composition, packaging and storage conditions of the product.
In this article, we will conduct an expert analysis of the products available in this retail network, and we will not rely on marketing promises, but will look at the technical aspects that really affect the life of the engine. Viscosity, alkaline And the additive pack are the key parameters that will determine whether the saving of your nerves and potential repairs are worth it.
Assortment and origin of products
The first thing that customers encounter is the variety of names, and on the shelves you can find canisters labeled "Luxstahl", "G-Energy" (in rare cases, the remains of lots), as well as the chain's own trademarks or little-known manufacturing plants. oil It is important to understand that a spill in itself at a third-party plant does not mean poor quality, but requires careful study of the label.
The main emphasis is on semi-synthetic and mineral compositions with viscosity 10W-40 and 5W-40These classes are most in demand in the budget segment and among owners of used cars. 5W-30 The packaging is usually standard, a plastic canister of 4 or 5 liters, sometimes 1 liter.
⚠️ Note: Pay special attention to the date of bottling. The oil has an expiration date, and it can be deposited in discounter warehouses. The old product loses its additive properties even if the canister has been sealed.
Manufacturers often do not advertise the specific chemical composition of the base, limiting themselves to general phrases about “hydrocracking basis”, this is standard practice for the budget segment, where the company is not a part of the industry. hydrocracking (HC-synthesis) makes it cheaper to make the product more synthetic, but with less work, and you're probably buying it from Light Light.
Chemical composition and base oils
The foundation of any lubricant is the base oil, and in the case of discounter products, the most likely candidate is the API group two or three, which is a deep refined petroleum product. Hydrocracking oils have good stability, but inferior to PJSC synthetics in frost resistance and resource.
The second important component is the additive package, which is what the oil does at high temperatures and stresses. Budget oils often contain a simplified package, with fewer detergents and dispersants. deposit It's not critical for older engines, but modern engines with narrow oil channels can be affected.
The third aspect is vaporization. Cheap bases tend to burn out at high temperatures. If you run a car in an urban cycle with frequent traffic jams, the oil temperature in the pallet can reach the temperature of the oil. 110-120°CIn such circumstances. flyfaction They evaporate, the oil thickens, and the oil levels drop, and the need for more extra tincture is more frequent, which partially offsets the savings when buying.
What is the viscosity index?
The viscosity index is a measure of how much viscosity changes with temperature. The higher the index, the more stable the oil is. In cheap oils, the index is often raised by polymer thickeners, which break down over time.
Comparison of specifications: Traffic lights vs. brands
To objectively assess quality, you need to compare declared and actual parameters with well-known mid-range brands. The difference often lies in details that are not visible to the naked eye, but affect the durability of the engine.
| Parameter | Traffic light oil (Budget) | Branded oil (Middle segment) | Premium synthetics |
|---|---|---|---|
| Basis | Hydrocracking/mineralka | Hydrocracking (VHVI) | PAO/Ester |
| Alkaline number (TBN) | 6.0 - 7.5 mg KOH/g | 8.0 - 9.5 mg KOH/g | 10.0+mg KOH/g |
| Frozen temperature | -30°C... -35°C | -35°C... -40°C | -45°C... -50°C |
| Replacement interval | 5,000 - 6,000 km | 8,000 - 10,000 km | 12,000 - 15,000 km |
As you can see from the table, the key difference is alkaline (TBN) This is the parameter that neutralizes the acids produced by combustion. A low TBN means that the oil oxidizes faster and stops protecting the engine from corrosion. If branded oils are the norm to replace every 10,000 kilometers, then for the oil from the "Svetofor" this interval should be reduced.
Also worth noting is the freezing point: for the southern regions of Russia, the difference between -30°C and -40°C is not significant, but for Siberia or the Urals, the use of oil with the worst ones is not significant. low-temperature This can lead to a difficult start in the winter and oil starvation in the first minutes of operation, a critical moment that cannot be ignored.
The main conclusion of the comparison: Budget oil from the discounter works, but requires a twofold reduction in replacement intervals to keep the engine healthy.
Impact on the engine and work life
The use of budget lubricants directly affects the life of the power unit. However, if you change it frequently, for example, every 5-6 thousand kilometers, the negative impact is minimized. The engine gets a fresh pack of additives, and the wear products are washed out. sludge And the lacquer deposits begin to actively precipitate on the details.
Modern engines with phase change systems (VVT-i, VTEC, Vanos) use oil pressure to control valves. If the oil thickens or becomes contaminated ahead of time, the valves jam, which leads to power loss and increased fuel consumption. traffic light oil It can cause expensive repairs.
On the other hand, for older 1.5-1.6-liter atmospheric engines produced in the 90s and early 2000s, this oil can be a great option: these engines are less demanding for lubrication quality, have large gaps and often already have a small carbon footprint, pouring expensive synthetics into them is not economically feasible, and cheap oil allows you to maintain the level and pressure in the system.
⚠️ Note: Do not use budget oil in turbocharged engines unless you plan to change it every 4-5 thousand kilometers. The turbine heats to high temperatures and requires stable lubrication, which cheap compounds can not provide.
Packaging and counterfeit protection
One of the main risks of buying oil from discounters is not so much the quality of the product itself as the conditions of its storage and the likelihood of counterfeiting. Plastic canisters often have simple printing. Barcodes can be unreadable, and application dates can be blurred. Authentication through a QR code on the label is often impossible, since little-known brands simply do not have a developed verification system.
Storage conditions in Svetofor stores also leave much to be desired: canisters can stand on pallets in direct sunlight or, conversely, in unheated warehouses in winter; UV destroys plastic and can affect the properties of the oil, and temperature changes lead to condensation inside the canister if it is not sealed. Water in oil This is guaranteed death for the crankshaft liners.
☑️ Checking the oil before buying
When buying, be sure to check the neck. On a quality product, there is always a control seal or membrane under the lid. If the lid is easily unscrewed without the characteristic crack or click, and the membrane is missing or glued, it is better to refrain from such a purchase, the risk of running into counterfeit or recycled “working” in this case increases many times.
Practical recommendations for application
If you do decide to use the lighting oil for your car, follow certain safety rules: first, shorten the replacement interval. This is the golden rule for any budget oil. Change the lubrication every 5,000 to 6,000 kilometers, and the engine will likely not notice the difference with expensive ones.
Secondly, make sure to change the oil filter. Often drivers save on the filter by relying on "normal" oil, or vice versa. For low-cost lubricants, the filter must be high-quality and new to capture possible oxidation products. A good filter will keep pollution out while the oil is still running.
Third, before the first pour of a new, unfamiliar oil, it is recommended to do an engine flush. Use a cheap wash oil or "five-minute" to remove the residues of the old product and possible dirt. This will allow the new oil to work in clean conditions from the start.
Tip: When you switch to low-cost oil, try to do a 3,000 km workout analysis. It's inexpensive, but it will show the real state of the engine and the rate of oil degradation.
Don't expect a cheap oil to do wonders. It won't make the engine quieter, more powerful, or more economical. It's just about lubricating rubbing surfaces and removing heat. If it can do it at 5,000 kilometers, that's a win for the old car owner's wallet.
Final verdict and conclusions
Motor oil from the Svetofor stores is a product with its pros and cons. It's not "death in the canister," as some people shout, but it's not the "elixir of youth" for the engine. It's a working tool for specific conditions: old cars, short replacement intervals, quiet operation. For modern technology with long intervals of maintenance and complex electronics, this option is not suitable well.
The main advantage of this oil is price. With the ever-increasing cost of car maintenance, the opportunity to save on consumables looks attractive. But the savings should not be too reasonable. If the price difference between a well-known brand and a nouneym is 20-30%, the risk can be justified. If the difference is three times, it is worth thinking about what makes it so cheap.
Ultimately, it's up to the car owner to make the choice, and if you're willing to change oil more often and keep track of the level, the product from the discounter will allow you to keep your budget, and if you prefer the "fill and forget for $15,000" principle, you'd better pay over and buy a proven brand with manufacturer's approval.
⚠️ Warning: Never mix oils of different manufacturers and different types (mineral with synthetics). Even if both are bought from the same store, their chemical bags can react and precipitate.
Can different colors of oils be mixed?
The color of the oil is not an indicator of its properties. Dyes are added for labeling. You can only mix oils with the same base and similar tolerances, but it is better to avoid this, since you can not predict the reaction of additives.
Frequently Asked Questions (FAQ)
Is it true that the “Svetofor” sells waste oil?
No, there is no official evidence of this, most likely, the lower grade oil (mineral or hydrocracking) with a minimum package of additives produced at large refineries is sold.
Which oil from the Light Forest is better to choose: 5W-40 or 10W-40?
For most regions of Russia and age cars are better suited 10W-40It's thicker, burns less and keeps pressure better in worn-out engines. 5W-40 You should only take it if you live in a cold climate or have a modern engine.
Can I put this oil in the gearbox?
Absolutely not. Transmission oils have a different composition of additives (often with sulfur and phosphorus content) that can destroy the catalyst and damage the transmission synchronizers or automatic transmission frictions if they get there. Use only specialized transmission fluids.
What is the real mileage that this oil can withstand?
The real safe mileage for properties is about 5,000–6,000 kilometers in a mixed cycle, and in a city with traffic jams, the resource can be reduced to 4,000 hours, which is equivalent to about 4,500–5,000 kilometers.
