BOP Fleet E7 15W-40 utilises novel dispersant chemistry which represents a significant upgrade in performance compared with more traditional engine lubricants. BOP Fleet E7 15W-40 provides greatly enhanced soot handling properties and greater protection to critical components such as main bearings, turbochargers and valve trains. It offers improved flow through oil filters, preventing by-pass and its associated problems. BOP Fleet E7 15W-40 is an ideal choice for use in a very wide range of heavy duty diesel engines such as those found in on-highway applications in trucks and buses, including certain Euro 4 and Euro 5 engines, as well as numerous off-highway applications in the agricultural and construction sectors. In addition, BOP Fleet E7 15W-40 may also be used in many marine inboard engines and generators. In particular, BOP Fleet E7 15W-40 is recommended where any of the following industry standard and OEM specifications are required and is backwards compatible to many older specifications which preceded them.
