John Deere Plus-50

By Rod Sutton, Editor in Chief | September 28, 2010

Plus-50 meets the needs of Deere engines. It exceeds API CI-4 levels for diesels and API SL for gas engines. The additive system is said to lower engine wear and provide superior protection against high-temperature thickening. Drain intervals can be extended by 50 percent over the operator's manual recommendation when Deere filters are used. Oil has excellent soot-handling capability, reducing sludge and decreasing parts wear.
