"While it does take longer for motor oil to pump in extreme cold temperatures, we are talking milliseconds, not minutes," Shell Marketing Manager and former Pennzoil Technical Advisor Shanna ...
This time ensures lubricating oil reaches all of the engine's vital parts. In addition to unnecessary engine wear, the Environmental Protection Agency says letting your car idle causes air ...
6. Fill Up on Antifreeze. Before the big chill sets in, make sure to top off your antifreeze -- but use a winter-specific formula. Antifreeze must be mixed with water, usually in an exact 50/50 ratio.
Motor oil, engine oil, or engine lubricant is any one of various substances used for the lubrication of internal combustion engines. They typically consist of base oils enhanced with various additives, particularly antiwear additives , detergents, dispersants , and, for multi-grade oils, viscosity index improvers .
An example would be the internal combustion engine of an automobile; the installation of heaters on the engine block and battery as well as the substitution of winter-grade coolants and lubricants allows the vehicle to start and run in sub-freezing conditions where a non-winterized engine would quickly break down.
An everyday example of cloud point can be seen in olive oil stored in cold weather. Olive oil begins to solidify (via liquid-solid phase separation) at around 4 °C, whereas winter temperatures in temperate countries can often be colder than 0 °C. In these conditions, olive oil begins to develop white, waxy clumps/spheres of solidified oil ...
"[Idling] does of course use fuel, and the bigger the engine, the more fuel," he said. Roots of a myth Some myths die hard, and the notion that you need to idle your car in the cold is no exception.
The grades with a W designation are considered Winter-grades, and denote an engine oil's low-temperature properties, while non-winter grades denote an engine oil's properties at the operating temperature of an engine. [5] The SAE 8 through SAE 16 viscosity grades describe oils that can improve fuel economy through reduced hydrodynamic friction ...
