Keep this in mind if you are checking tire pressures. Generally, for every 10-degree Fahrenheit rise in ambient temperature, your tire's inflation pressure will go up by about 1 psi. Also, an improperly inflated tire can heat excessively, potentially leading to a blow-out on the highway. Change the engine oil and adjust the viscosity grade. This isn't as hard as it sounds.
Viscosity refers to the thickness of the oil.
For example, maple syrup has a higher viscosity than water. Engine oils are sold with different levels of viscosity, and many of them are also multi-viscous, which means the oil's thickness can change depending on its temperature. Generally speaking, the warmer the oil is, the thinner it will be. If the oil is too thin, the engine might not get the proper lubrication. To solve this summertime issue, you can change your vehicle's engine oil to one that is a little thicker.
