AMSOIL Series 3000 5W-30 Synthetic Heavy Duty Diesel Oil Discontinued

Due to diminishing sales, AMSOIL Series 3000 5W-30 Synthetic Heavy Duty Diesel Oil is discontinued and available while supplies last.  If you are using Series 3000, it's best to upgrade to Signature Series Max-Duty 5W-30 Synthetic Diesel Oil.
​
While AMSOIL's previous-generation synthetic diesel oils set the bar for quality and protection for over 20 years, Signature Series Max-Duty Synthetic Diesel Oil exceeds the latest API CK-4 specification and represents a serious upgrade in protection and performance compared to oils formulated for previous API diesel oil specifications, including API CJ-4 and CI-4+
​

• More piston-scuffing protection for reduced wear
• Better thermal control to resist oil thickening, aid in cooling and reduce wear
• Improved shear stability for maximum resistance to oil consumption and wear
• Enhanced aeration control, promoting oil-pump efficiency, wear protection and heat resistance

API CK-4 diesel oils are backward-compatible, meaning they are recommended in all applications specifying API CJ-4, CI-4+ (and prior) specifications.

*than required by the Detroit Diesel DD13 Scuffing Test for specification DFS 93K222 using 5W-30 as worst-case representation.
