No matter how hot, cold, steep, dusty, muddy or extended your operations, you need to know that your oil will protect your engine under all conditions. 

The Energised Protection of Shell Rimula heavy-duty diesel engine oils works relentlessly in three critical areas:

  1. Acid control – well-proven performance additives help to protect against corrosion from acids formed as fuel burns.
  2. Deposit control – helps to keep the engine clean for consistent performance and long life.
  3. Wear control – keeps moving metal engine surfaces apart for long engine life.

Shell Rimula R5 LE

Shell Rimula R5 LE is an innovative heavy-duty engine oil, designed to protect under the full range of pressures and temperatures found in modern engines. This makes it the ideal choice for operators of heavy-duty on- and off-highway vehicles.

Designed to deliver fuel economy savings, extended drain capability, enhanced engine cleanliness, and excellent wear protection, Shell Rimula R5 LE meets API CJ-4 specifications for increased compatibility with the latest exhaust-emissions control systems.


Protective power
Shell Rimula R5 LE is a semi-synthetic lubricant which uses a unique technology that adapts chemically and physically to meet the changing needs of your engines. The combination of synthetic and conventional base oils and advanced additive components delivers excellent protection, even at low temperatures when the enhanced cold flow properties help to protect your engine against wear.
Shell Rimula R5 LE is formulated to energise the oil's performance, provide improved low temperature flow and to deliver an advanced 'Low-SAPS' formulation which helps to control the blocking or poisoning of exhaust after treatment devices.

Specifications and approvals

Technology Leadership
Shell Lubricants is among the first to offer semi synthetic SAE 10W-30 and SAE 10W-40 viscosity grade products that meet some of the most stringent heavy-duty engine oil specifications globally, such as API CJ-4, ACEA E9, and Volvo VDS-4. Shell Lubricants is committed to being the technical leader in heavy-duty engine oil product innovation.


Fuel economy benefits
Shell Lubricants continues to be a leader in the development of fuel-economy-enhancing lubricants, providing real fuel savings that can help lower operation and maintenance costs. In 2009, we conducted a large scale trial of medium-duty trucks based on city and highway driving patterns.

Use of Shell Rimula R5 LE 10W-30 viscosity grade demonstrated fuel savings of up to 1.6% in medium-duty trucks (for highway cycles, compared to conventional SAE 15W-40 engine oil).


Optimise oil drain intervals
Shell Rimula R5 LE provides protection against acid build-up that can contribute to corrosive wear, as demonstrated through Total Acid Number (TAN) increase and lead corrosion in several industry standard engine tests. By controlling TAN increase, Shell Rimula R5 LE can help equipment owners optimise oil drain intervals.

Low temperature performance

In harsh winter climates, using Shell Rimula R5 LE 10W-30 or 10W-40 can help to protect the durability of your starter and battery and help your engine start more easily than with a 15W-40 viscosity grade product.

 

Wear protection/deposit control

Shell Rimula R5 LE provides excellent wear control particularly in preventing bore polish in the cylinder liners – a problem which can result in a loss of fine manufactured honing lines, leading to excessive liner wear and an increase in oil consumption.

Control of bore polish can be measured through the stringent Volvo D-12D engine tests. As shown Shell Rimula R5 LE does an excellent job controlling bore polish in this engine test at a performance level comparable to 15W-40 viscosity grade products.

Shell Rimula R5 LE also provides wear and deposit control to help protect your engine's most critical components. Excessive wear of the cam lobes and tappets can lead to loss of power and increased engine emissions. Control of wear in the valve train components is measured in the stringent Mercedes-Benz OM-646 LA engine test. As shown in the pictures there was minimal wear in the used camshaft after running for 300 hours using Rimula R5 LE 10W-30.


Cleanliness and deposit control
Shell Rimula R5 LE provides exceptional piston deposit control, exceeding the MB228.51 performance levels for piston cleanliness control in the OM-501 LA engine test – one of the most demanding tests in the industry. Excessive deposits on the piston can lead to bore polish and scuffing on the cylinder liner, which can result in increased oil consumption. Even after running for 300 hours in the OM-501 LA test with Shell Rimula R5 LE, there are minimal deposits in the top ring and second land.

Should you use Shell Rimula R5 LE?
Shell Rimula R5 LE meets the specifications and is approved by a wide range of engine manufacturers for use in current and legacy engines. It’s an excellent choice for operators of vehicle fleets in locations with large ambient temperature ranges: one oil to protect, whatever the season.

Shell Rimula R5 LE delivers enhanced performance and protection of the latest low emission engines, especially those fitted with exhaust diesel particulate filters (DPF). It’s suitable for modern low emission heavy-duty engines, especially those with exhaust after treatment devices, in place of an SAE 15W-40 engine oil.


How to use R5 LE oils safely
Shell Rimula R5 LE oils are unlikely to present any significant health or safety hazards as long as you use them properly in the recommended application. You should avoid contact with skin and wear impervious gloves with used oil. If the oil does come into contact with your skin, wash immediately with soap and water. To dispose of used oil, please take it to an authorised collection point. Do not pour it into the earth, drains or water.
