Oil / Lubricants

Written by Kevin Schappell

I receive a lot of questions regarding oil andrepparttar least understood part isrepparttar 102746 number system used to rate oils. Oil weight, or viscosity, refers to how thick or thinrepparttar 102747 oil is. The temperature requirements set for oil, byrepparttar 102748 Society of Automotive Engineers (SAE) is 0 degrees F (low) and 210 degrees F (high). Oils meetingrepparttar 102749 SAE's low temperature requirements have a "W" afterrepparttar 102750 viscosity rating (example: 10W), and oils that meetrepparttar 102751 high ratings have no letter (example SAE 30). Oil is rated for viscosity by heating it to a specified temperature, and then allowing it to flow out of a specifically sized hole. Its viscosity rating is determined byrepparttar 102752 length of time it takes to flow out ofrepparttar 102753 hole. If it flows quickly, it gets a low rating. If it flows slowly, it gets a high rating.
