FAQ:
Q: What is the difference between 10W40 and 15w40 oil?
A: A 10W40 oil will be thicker in the cold than 15W40 oil, but they will have the same viscosities at higher temperatures. The winter viscosity number dictates cold-start performance. A lower number indicates that the cold oil will be thinner, hence applying less static friction on the engine, and less drag.
Q: What do cars use 10W40 motor oil?
A: Drivers commonly use 10W-40 motor oil in vehicles with higher mileage because the oil is thicker while the engine is hot; this helps lubricate older moving parts. This oil is meant to start up vehicles in winter climates that experience temperatures of 10 degrees Celsius.
Q: What does 10W-40 mean in motor oil?
A: Motor oils come in different weights or grades, and one of the most common for consumer vehicles is 10W-40. This designation refers to the viscosity of the oil in different temperature ranges. Viscosity refers to how easily a given liquid flows.
Q: Can I use 10W40 in my vehicle?
A: You can apply the 10w40 motor oil in vehicles which have higher mileage because this oil is thicker when the engine is hot, thereby helping to lubricate older moving parts. Use 10W40 to start up vehicles in winter climates of temperatures about 10 degrees Celsius. 10w40 is not as reliable as 5W40 oil for engine startup in colder winter climates.
