Synthetics at a low price - Rosneft 5W40 oil. This is exactly how many owners of Russian car brands answer. Despite the fact that Rosneft is a very large supplier of motor lubricants and other substances, there are nuances that need to be taken into account when using the product.
Once a very young guy approached me, to whom his parents gave him a car. Immediately after filling this oil, the engine began to “sneeze” and “cough”. When they began to figure out what and why, it turned out that the problem was precisely the lubrication.
And it’s not that it’s bad or of poor quality, it’s just that the guy’s car was foreign, and the lubricant was not suitable for it. According to my own feelings, the oil is not bad for a budget option. However, to explain this clearly, I will make a short review on the topic.
Product Description
Rosneft Magnum Ultratec 5w40 automobile oil is a fully synthetic lubricant for gasoline and diesel engines of passenger cars and small commercial vehicles. A unique feature of the product is approval from the world's leading automakers and a salicylate additive package that reliably protects the engine from deposits of various origins.
Lubricant is an all-season product. It fully retains its functionality at temperatures from -350C to +400C.
In addition to Rosneft Magnum Ultratec 5w-40 oil, the brand’s line includes other products, for example, a lubricant with the similar name Rosneft Magnum Ultratec A3 5w-40. Its distinctive feature is a special, slightly different package of additives, the development of which focused on protecting the engine during active city driving.
The entire Ultratec line is motor oils with the highest performance characteristics, developed specifically for modern engines. Along with others, it is part of the premium Magnum series. A distinctive feature of the new series is the use of the company’s advanced developments, high-tech equipment and customization of production. When developing the formula for new articles, engineers carried out laboratory analyzes and bench tests, many of which were unique in the world.
Each Magnum consumable is made from its own synthetic base, which the company began producing in 2017.
Technical characteristics, tolerances, specifications
| Complies with class | Explanation of the designation |
| API SN/CF | SN - for gasoline engines. Small amount of phosphorus in the composition. Compatible with exhaust converters. Energy saving properties. Equivalent to ILSAC, with the difference that API SN requirements do not require the Sequence IIIG wear resistance test on aged oils and the Sequence VID energy efficiency test. CF - ensures clean parts. Units with indirect injection, not demanding on diesel quality or running on fuel with a sulfur content of up to 0.5%. Suitable for oil systems with turbocharger or compressor. |
| ACEA A3/B4, A3/B3 | A3/B4 - for units with a turbine, direct injection and pump injectors or a Common Rail system. Almost completely identical to A3/B3, but suitable for new injection systems. May replace the previous category. A3/B3 - for engines of passenger cars and light trucks with high power, with or without turbocharging. Average replacement interval. Can be used in any season. |

How to spot a fake
No matter how high-quality the motor oil is, no matter how many approvals and advantages it has, the car owner will never know about them if he buys a fake canister, which can contain not only a product of lower quality, but also a spindle or waste.
When choosing a canister, take a closer look at those places and markers that are difficult to repeat in artisanal conditions. So, the original packaging should have a die-cut company logo that fits seamlessly into the rest of the plastic. It is worth taking a closer look at the quality of welds and corners. No lubricant should leak through them.
How to distinguish an original from a fake?
The counterfeitness of an oil can be judged by its cost, especially if it is underestimated by 10-20% compared to the recommended one. Unreasonably cheap samples are often found in small limited liability stores, which can make the injured buyer to blame.
In large retail outlets, counterfeit oil can cost as much as the original product. And yet, responsibility for counterfeiting falls on the unscrupulous seller, so the likelihood of encountering a counterfeit in such stores is minimal.
Let's look at a number of signs by which real Rosneft Magnum Ultratek 5W-40 oil can be distinguished from counterfeit oil.
The original plastic packaging has inclusions and can shimmer in the light, like metallic car paint. The surface of the canister is smooth, with smooth edges, without casting defects (sinks, burrs, etc.).
A container made of heterogeneous plastic indicates a counterfeit. It is usually thin and translucent so much that the joints of the two halves of the canister are visible. It is possible that there is an unpleasant odor, as well as uneven markings on the oil level scale.
The label is a source of information about the product, as well as an important element of protection against counterfeiting. The text on the stickers must be clear and free of spelling errors. The original label is glued smoothly and without bubbles, it is not easy to pry it off with a fingernail. A fake can be identified by the quality of the printing: the images on the stickers are blurry, faded and uniform, without gradients.
The date of manufacture of the canister indicated on the bottom should be earlier than the date of manufacture of the oil itself. The stamp should not have any abrasions or other defects. The original product must contain information about the batch number and expiration date.
The lid of real oil is secured against accidental opening with a retaining ring-seal with antennae. When opening the canister they break. Fraudsters use regular glue instead of a retaining ring, which can cause oil to leak out when the container is turned upside down.
The barcode or manufacturer's logo located on the side of the cap and ring splits into two halves when the cap is opened. It is not possible to accurately combine them in artisanal conditions.
On the original oil, at an angle, you can see a protective hologram shimmering in the light in the form of the Original or Genuine symbols. When the canister is opened, it is destroyed, so it is difficult to counterfeit.
The relief of the ribs on the lid of the fake canister is narrower than in the original. Counterfeit products often lack brand engraving.
Reviews of Rosneft 5W-40 oil
To get a complete picture about the product, it is worth citing several reviews from real users who described the product on the Internet.
Konstantin Ch., 43 years old
I have been buying oil for a long time and chose it consciously. Despite the fact that the product is low in cost, it fully meets all my needs. Oil is used sparingly and the engine lubricates as it should.
Dima, 29 years old
What I like about this product is that it allows the motor to run smoothly and without any problems. I've been using the oil for about a year. I changed it once, but I drive the car often and a lot. I check it periodically, the oil has darkened, they think it is of high quality.
Maxim, 32 years old
The oil is standard, but easily copes with loads. Allows you to start the car well and quickly, has excellent lubricating properties. The car starts right away in winter. I don’t have to top it up often either, and in general, the machine runs much quieter and without vibration. This is important for me, so I give the oil a plus.
Igor, 50 years old
In my opinion, the quality of the oil fully corresponds to its price. For a domestic car, the product is suitable, although my friend poured oil into a foreign car and it began to act up. What do I mean, Rosneft is probably for Russian cars and you shouldn’t think otherwise. Overall, the oil is not bad.
Positive and negative characteristics of the product
Rosneft 5W40 motor oil is one of the most popular products produced under this brand. An important advantage of the oil is its affordable price (from 1112 for 4 liters), which does not make it profitable for fraudsters to counterfeit this product.
As additional positive properties, the following indicators can be noted:
- full compliance with the technical specifications declared by the manufacturer;
- the product can be poured into different types of engines;
- the oil has good cleaning and dispersing properties;
- the composition does not form soot;
- economical to use.
All of the above can be supplemented by the fact that the oil can be used for “aged” cars and even at very low temperatures (from -35 to +40).
The product also has disadvantages, and they lie in the too narrow range of oil use. Many buyers report that it is effective to pour oil only into Russian cars, but for foreign ones, it is not very suitable.
