Shell across the range

To cope with the differing requirements of Exhaust Gas Recirculation or selective catalytic reduction devices, Shell has launched Rimula Signia 10W-40 oil for both types of Euro 4 emissions requirements. In addition to being formulated for all engine types - old, new, European and North American - Shell says it keeps pistons clean and protects valve trains.

For low emission engines it is formulated to control soot and viscosity and minimise contamination of after-treatment systems. The profile meets or exceeds, among many others, API CI-4 specification.

The Rimula range includes:

Rimula Ultra 5W-30 and 10W-40 fully synthetic, heavy-duty diesel engine oils for European engines, to give extended maintenance interval protection against piston and engine deposits;

Rimula Super FE 10W-40 semi-synthetic, designed for all modern diesel engines and to improve fuel efficiency and give cold start and low temperature protection;

Rimula Super 15W-40, designed for all modern diesel engines used in road transport and construction internationally;

Rimula X 15W-40, designed for most on-or off-highway applications to deliver lower engine wear and longer oil life.
