The International Energy Agency (IEA) has predicted that carbon emissions resulting from energy generation will peak in just a few years in what it calls a “historic turning point”. Continue reading IEA: Energy-related carbon emissions to peak in 2025
From cars and trucks to vans and motorcycles, vehicles of all kinds require dedicated lubricants to keep them in excellent working order. Continue reading What are the two main lubricants used in most motor vehicles?
In what has become a regular occurrence, the US-based energy major ExxonMobil has made two further discoveries in the Stabroek block off the coast of Guyana.
According to the company, the drillship Stena Carron drilled both the Yarrow-1 and Sailfin-1 wells. The former was drilled in 1,085 metres of water and met with about 23 metres in hydrocarbon-bearing sandstone, while the latter was drilled in 1,407 metres of water and met with 95 metres of hydrocarbon-bearing sandstone.
ExxonMobil Upstream Company’s president, Liam Mallon, said that the company’s success in exploring for, and developing, resources in Guyana’s waters was thanks to its people, its expertise and an emphasis on optimising all operational aspects, adding:
“We are committed to responsibly and safely developing this world-class resource to help meet global demand for secure, reliable and lower-emission energy. Our investments through the pandemic have allowed us to increase supply at this critical time, while creating value for the people of Guyana, our partners and shareholders.”
ExxonMobil, which also makes popular lubricants like the Mobil SHC gear oil, says it has accelerated its development and production in the Stabroek block at a faster than average rate for the industry. Its first two projects, Liza Phase 1 and 2, produced almost 360,000 barrels per day of crude oil on average in the third quarter, which is actually greater than their design capacity. As further projects come online this decade, ExxonMobil expects the oil production in Guyana to exceed a million barrels per day.
Engine oils are available to buy with a wide range of different levels of viscosity or thickness. As a rule, the engine oil that you should use in your vehicle will be dictated by its make and model and this extends to its viscosity. Therefore, to find the thickest oil you can put in your car, you should always consult the recommendation provided by its manufacturer. Read on as we explore oil thickness in greater depth and explain how to select the right option for your ride.
Engine oil viscosity is a term that refers to how easily an oil pours at a particular temperature. For example, thin oils will have lower viscosity and therefore pour more easily at lower temperatures than oils which are thicker and have higher viscosity levels. A thin engine oil will reduce friction between metal parts within engine’s system, but also will help engines to start quickly when the weather is cold. However, thicker oils are better at maintaining both oil pressure and film strength at higher loads and temperatures.
The Society of Automotive Engineers (SAE) created a viscosity scale for engine oils.
Viscosity is referenced on products using the common “XW-XX” classification. The number before the “W”, which stands for winter, rates the engine oil’s flow at -17.8 degrees Celsius and the lower this number is, the less the engine oil will thicken in cold temperatures.
The numbers following the “XW” indicate engine oil flow at 100 degrees Celsius and display the oil’s resistance to becoming thin at higher temperatures.
For example, oil that has a 5W-30 grade will thicken less than engine oil that has a 10W-30 grade in colder weather. Engine oil with a 5W-30 grade will thin out more swiftly at higher temperatures compared to oils that have a 5W-40 grade.
In winter and for vehicles used in colder climates, engines benefit from using motor oil that has low winter viscosity. However, in summer and in warmer regions, an engine will benefit from oils with higher viscosity grade at 100 degrees Celsius.
Along with consulting your vehicle specifications and manufacturer recommendation, to work out the best thickness of oil for your car, always take into consideration the regional climate that your vehicle is operating in and whether it is summer or winter.
Sergio Perez, one of the drivers for the Red Bull Formula 1 team, has highlighted the role that its technology partner ExxonMobil has played in helping the team to win on the racetrack, describing it as the “secret sauce”. Continue reading Formula 1 driver credits ExxonMobil for racetrack success
The latest cars coming off the production line from leading automakers are designed with engines optimised for efficiency, performance and active service life. However, to keep engine components protected and able to move freely, a fresh supply of lubrication is essential. Continue reading What type of lubrication is used in modern cars?
Prince Abdulaziz bin Salman, the energy minister of Saudi Arabia, has defended the recent controversial production cuts by the OPEC+ group, while signalling that his country stands ready to increase production again if upcoming sanctions on Russia, or other unforeseen events, lead to a supply shortage. Continue reading Saudi Arabia signals willingness to supply more oil if needed
Ensuring that brake fluid remains topped up is essential. Without it, a braking system will stop functioning, putting the lives of those onboard and other motorists on the road in danger and potentially harming your vehicle. Continue reading How to check and top up your brake fluid
In working engines and equipment, many metal components operate in proximity to one another. If the surfaces of these moving metal parts come into contact with one another, friction and undue wear will occur. Continue reading What is the best lubricant for metal on metal?
10W40, 15W40, and 5W30 are common designations users come across when selecting engine lubricants. These figures signify an engine oil’s dedicated viscosity grade, which refers to the lubricant’s efficiency and fluidity levels. Continue reading What are the different viscosity grades?
