Tierra 400 XSP SAE 5W-40

Tierra 400 XSP SAE 5W-40 is a mixed-fleet engine oil recommended for naturally aspirated and turbocharged fourstroke diesel engines and four-stroke gasoline engines. It helps keep piston rings clean and free for optimum combustion pressure and minimal wear.

A high level of ashless dispersants keeps fuel soot in suspension and helps to avoid filter plugging, cylinder head sludge, abrasive wear, viscosity increases, and oil gelation. These problems could cause excessive engine wear and bearing failure, without warning. Optimized additive chemistries combined with synthetic base stocks control oxidation, sludge, and undue thickening between oil drains. A de-foaming additive helps prevent air entrapment.
