Oil viscosity in Summer

Engine oil viscosity refers to how oil flows at different temperatures. Thin oil pours easier at low temperature than thick oil that has higher viscosity. The viscosity grades are represented by two numbers. The first number usually indicates how oil flows in cold temperatures, while the second number represents its flow in hot temperatures. Lower viscosity oils flow more easily in cold conditions, while higher viscosity oils provide better protection at high temperatures.

Heat normally causes oil and other lubricants to be thinner, and thus less effective at lubricating engine parts. So using heavier oil or an oil with a higher viscosity grade will ensure better protection and performance. Oil with high viscosity will maintain optimal thickness and lubrication in the hot weather conditions.

In summer, heat is considered a real threat to the internal parts of the engine. For that reason, a higher viscosity grade, such as 10W-40 or 15W-40 (which is recommended by TotalEnergies), is best to be used for engine oil. These grades keep the oil thick and ready to lubricate the engine even at high temperatures, ensuring optimal engine protection and performance by preventing the oil from becoming too thin under the heat.

Using the wrong viscosity grade in summer can lead to several issues. If the oil is too thin, it may fail to adequately lubricate engine parts, causing increased friction, wear, and overheating. On the other hand, if the oil is too thick, oil will not flow properly, which will lead to reduced fuel efficiency and will make starting the engine harder. In both cases, engine damage is inevitable and results in costly repairs. Choosing the right viscosity ensures the engine runs smoothly and efficiently under summer heat. TotalEnergies provides all the help you need in choosing the right grade of viscosity for your engine.

If you live in a hot country, all you need in order for you to choose the right oil for your engine is to check the oil products provided by TotalEnergies. The following tips will help you more in your choice:

• Check manufacturer's recommendations

  Always refer to your vehicle's manual for the recommended oil viscosity grade for summer.

• Consider higher viscosity

  Choose a higher viscosity grade like 10W-40 or 15W-40 to ensure better lubrication in hot temperatures.

• Keep an eye on oil levels

  Regularly check oil levels and top up as necessary to maintain optimal engine performance.

• Synthetic oils

  Consider using synthetic oils, which often perform better under extreme temperatures and provide consistent lubrication.

• Frequent oil changes

  Hot weather can degrade oil faster; schedule more frequent oil changes to maintain engine health.

• Inspect for leaks

  Heat can increase oil leaks; inspect your engine for any signs of leakage and consider a repair.
