How to pick the right motor oil for your car?

27 July 2018

Research and Productive Trading company company SUPROTEC was established in Saint Petersburg in 2002. The company possesses modern scientific and technical capabilities and professional scientists and engineers that manage a modern laboratory, providing high-tech manufacturing facilities that correspond to the European standard ISO 9001.

Choosing the correct motor oil for your car might seem daunting but the best way to start is by checking your owners manual for your car manufacturers suggested oil weight. Adjust this weight based on the weather (more on that later) and then start choosing a specific motor oil brand by checking out the starburst symbol that indicates the oil has been tested and meets the standards of the American Petroleum Institute (API). In addition, there's a 2-character service designation on the container. API's latest service standard is "SL." SL refers to a group of laboratory and engine tests, including the latest series for control of high-temperature deposits. Your third task is to pick the viscosity (thickness) that's suitable for the temperatures your vehicle normally operates in (check your owners manual), and you're done. Well, not quite. There's a whole lot more to the story than that.

Viscosity (a fluid's resistance to flow) is rated at 0 F (represented by the number preceding the "W" [for Winter]) and at 212 F (represented by the second number in the viscosity designation). So 10W-30 oil has less viscosity when cold and hot than does 20W-50. Motor oil thins as it heats and thickens as it cools. So, with the right additives to help it resist thinning too much, an oil can be rated for one viscosity when cold, another when hot. The more resistant it is to thinning, the higher the second number (10W-40 versus 10W-30, for example) and that's good. Within reason, thicker oil generally seals better and maintains a better film of lubrication between moving parts.

At the low-temperature end, oil has to be resistant to thickening so that it flows more easily to all the moving parts in your engine. Also, if the oil is too thick the engine requires more energy to turn the crankshaft, which is partly submerged in a bath of oil. Excessive thickness can make it harder to start the engine, which reduces fuel economy. A 5W oil is typically what's recommended for winter use. However, synthetic oils can be formulated to flow even more easily when cold, so they are able to pass tests that meet the 0W rating.

Once the engine is running, the oil heats up. The second number in the viscosity rating--the "40" in 10W-40, for example--tells you that the oil will stay thicker at high temperatures than one with a lower second number--the "30" in 10W-30, for example. What's really important is that you use the oil viscosity your car's owner's manual recommends.

In the conditions of our country with serious temperature differences, unreliable fuel quality at gas station and often traffic jams driving so-called Longlife oils are more appropriate because the oils possess the increased life cycle which is suitable for high-loaded engines. Synthetic oils are made for high-tech engines. If these oils pass stringent special tests (indicated by their labeling), it means they have superior, longer-lasting performance in all the critical areas, from viscosity index to protection against deposits. They flow better at low temperatures and maintain peak lubricity at high temperatures.

Thus Suprotec placed technical specification at ROWE MINERALOELWERK (Germany) for the development of motor oils for cars 5W-30, 5W-40 and transmission 75W-90. It is synthetic technology-based, premium, multi-grade, low-viscosity engine oil for car petrol and diesel engines with and without turbocharger including soot particle filter. This premium product is perfectly suited as a rationalisation oil according to manufacturer specifications.

ROWE MINERALÖLWERK GMBH is a continually growing company in the lubricant industry and based in Worms. Established in 1995 the company expanded, so that its head office was moved to Palatine Bubenheim in the year 2000. Given increasing demands and further required production capacities, the new head office in Worms was then opened on December 9, 2013. High product quality, short delivery periods and attractive prices make the DIN EN ISO 9001:2008-, ISO/TS 16949:2009- and ISO 14001-certified company a recognized partner, also for major clients at home and abroad.

The product range includes engine oils, gear and hydraulic oils, industrial and metalworking lubricants, bio-lubricants and fuel additives, but also radiator and window antifreeze, as well as various car care products. Further product ranges include lubricants for two-wheelers, utility vehicles, boats and cogeneration units. Over and beyond these, the product portfolio also includes the multi-purpose and high-performance greases manufactured in our own grease plant since 2015.

The main distinctive property of a series of the SUPROTEC Atomium products is considerable decrease in intensity of wear and as a result essential increase in the resource of the engine. Besides, the structure provides decrease in losses on friction, i.e. decrease in fuel usage and has low evaporability that provides decrease in waste of oil for car engines. Completely synthetic basis and the innovation package of additives provide excellent thermo - and oxidizing stability what guarantees increase in the resource of the oil by 1,5-2 times. The producer guarantees that motor oils SUPROTEC Atomium conform to the most strict specifications and international standards and are recomended to use in engines of modern cars of all types and brands.
