Mag 1 Conventional 10W-40 Motor Oil. CONVENTIONAL MOTOR OIL PASSENGER CAR MOTOR OIL CONVENTIONAL MOTOR OIL with FMX FORMULA API SP, exceeds ILSAC GF-6A, Replaces SN Plus, SM, SL, SJ, SH, SG, SF (obsolete) Manufactured in the USA MAG 1® Conventional 10W-40 Motor Oil is formulated for older vehicles and/or high-temperature climates, if thicker oil is preferred. It also provides the following benefits: Resists thermal breakdown and reduces deposit formation for longer, better engine protection. Additives work to keep engines clean. Provides a strong film barrier to control friction, resist wear and keep metal surfaces from coming into contact. CONVENTIONAL MOTOR OIL With EVOLUTIONARY PERFORMANCE™ MAG 1® with FMX® Technology – Friction Management for Xtreme protection™ provides these benefits: PERFORMANCE Controls friction and wear. Engineered to handle the most severe or extreme environmental conditions and engine stress. STRENGTH Provides a strong oil film to avoid metal-to-metal contact, even under extreme stress. Excellent wear protection. Advanced molecules bond together to prevent metal-to-metal contact of rotating engine parts. Improved friction reduction. MAG 1 oils react to heat to produce a critical friction-reducing barrier that protects metal surfaces.¹ Long service life Stands up to the heat and shearing so it extends oil life. Excellent oxidation and deposit control. Retains viscosity and prevents thermal breakdown. The oil excels even in the harshest conditions. To measure friction reduction benefits, engineers used the ball-on-disk traction test. APPLICATIONS Provides performance benefits for passenger cars, light trucks and sport utility vehicles; plus new and rebuilt engines.
