Oleum

Description

Description:
Well Oleum meets the warranty requirements where American Petroleum Institute (API) certified oil is
specified. These viscosity grades are also classified by API as “Resource Conserving” engine lubricants
and meet or exceed the latest industry specification ILSAC GF-5 / API SN. Those claims are backward
compatible with earlier performance levels such as API SM, SL, and SJ and previous ILSAC categories.
Application:
Well Oleum 10W40 and 10W-30* are recommended for gasoline fueled automobiles and light duty
trucks requiring an API SN, SM, SL or SJ. They also meet ILSAC GF-5 (Starburst Certification
Symbol).Well Oleum 10W-40 and 20W-50 are recommended for gasoline fueled automobiles and light
duty trucks where a higher viscosity API SN, SM, SL, SJ oil is preferred recommended .Well Oleum
20W-50 has a higher viscosity reserve which provides engines with full protection under higher
operating speeds, temperatures, and other adverse conditions.
Benefits:
Excellent engine cleanliness.
Engine protection under a wide variety of operating conditions.
API SN / Resource Conserving for Well Oleum 10W30, 10W40 and 20W50.
Helps reduce engine wear and corrosion.
Meets or exceeds the latest industry specification (ILSAC GF-5 / API SN: Well Oleum 20W50,
10W40, and 10W-30*).
Easy cold starting.
Guaranteed protection with the Well Oleum Limited Warranty.
