Rehvikeskus and Jungent, Shell lubricants’ official representative in the Baltic States, started working together in 2011 when Rehvikeskus began using high-quality Shell lubricants in our workshop. In 2019 we reinforced our partnership further when Rehvikeskus became the first official Shell Helix brand workshop in Estonia. The basis of our cooperation is common goals, a high standard of quality and both parties’ mission to be the preferred and most trusted partner in automotive care for consumers.
One of the deciding factors in this decision was Shell’s leading motor oil production technology.
Shell started looking for raw material and technology alternatives to oil because of the oil crisis in the early 1970s. In 1973, Shell’s scientists at Technology Centre Amsterdam were able to produce the first grams of base oil from natural gas.
Production of the innovative Shell Helix motor oils is based on unique Shell PurePlus technology, which uses GTL base oil, made specifically from natural gas, as its own base oil. Shell PurePlus technology is a complex process which provides crystal-clear base oil with none of the obvious impurities of crude oil. Furthermore, the entire production process is covered by more than 3500 patents.
Quality motor oil binds combustion residue, which would otherwise collect on the parts of the engine. As a result, quality motor oil will take on a darker colour soon after an oil change. One important aspect is the soot created during combustion, which has an identical composition to diamonds: both are very abrasive materials. If the motor oil cannot bind the soot, then a layer of it will form on the engine’s pistons, valves and other components. This in turn will cause faster wear and tear and greater fuel costs, and at the same time reduce the engine’s output. Moreover, quality motor oil helps keep oil channels free of sediment, which in turn ensures the necessary quantity and pressure of oil in the engine for it to perform flawlessly.
Quality motor oil flows exceptionally well even at low winter temperatures. This means that during a cold start the oil remains stagnant for a shorter time, and as a result there is less wear on the engine and it extends the usability of the motor. In addition, quality motor oil ensures the reliability of the motor and its output even at the highest working temperatures.
Driving conditions dictate how often you need to change the oil. Severe driving conditions include driving continuously for less than 20 km while starting your car only once, in an urban setting when you start and stop the car multiple times, being stuck in traffic or driving regularly on dusty roads. In these cases, you should change your oil in accordance with the guidelines set by your car’s manufacturer for severe driving conditions. For example, if the manufacturer suggests an oil change every 30,000 km for normal driving conditions or every 15,000 km for severe driving conditions, then in the aforementioned cases you should change your oil every 15,000 km. Normal driving conditions are basically long drives on motorways, driving more than 20 km and from one town to another.
Using bio-additives or biofuel makes a difference. In comparison to the combustion residue left by crude oil-based fuels, the combustion residue from biofuels is much more acidic, which accelerates the aging process of motor oil. As a result, it is beneficial to reduce the average requirement set for oil changes for severe traffic conditions by a third. In this case, you should change your motor oil every 10,000 km instead of every 15,000 km.
If you drive less than this during a year, then you will need to change your motor oil annually.
