Beta Marine ‘Lubricating Oils’

You may have noticed that we are now supplying several of our filters in our new ‘Beta Marine – Genuine Parts’ coloured packaging. Over the next months you will be seeing more of this packaging. We have also introduced Beta Marine lubricating oil that will become available at Chandleries on the Inland Waterways over the next year.

  • 15W-40 mineral based multigrade oil specifically suitable for low revving naturally aspirated and turbocharged marine diesel engines.
  • Maximum engine protection whilst reducing deposits and corrosion on all components; ensuring longer engine life and optimum performance even under arduous conditions and winter periods.
  • Ultimate protection from low temperature starting down to -25°C, and high operation at ambients of +55°C.
  • Meets the performance requirements of API (American Petroleum Institute) Classification CF (CD & CE have been replaced by CF); SL and CH-4; Volvo: VDS-3; Cummins: 20071/72/76/77; VW: 500.01, 505.00; MAN: M3275; Renault: RVI RLD; Mercedes Benz: 228.3, 229.1.
  • Available in 20 litre, 5 litre and 1 litre containers.

Lubricating Oil for Beta Marine Engines

Engine lubricating oil quality should have the minimum properties of the American Petroleum Institute “API” classification CF (CD and CE have been superseded by CF). A good quality SAE 15W/40 mineral based multigrade oil as used in most car diesel engines will meet requirements. An acceptable alternative are mineral based lubricating oils that are sometimes called semi-synthetic (or ‘synthetic blends’) and are blends of mineral oil with no more than 30% synthetic oil. The following table gives grades of oil viscosity required for various ambient temperature ranges.

Ambient TemperatureMulti-Grade Oil
-30°C to 0°CSAE 15W/30
-15°C to +15°CSAE 15W/40
0°C to +30°CSAE 15W/40
25°C and aboveSAE 15W/40

Note: Do not use lubricant additives, and we do not recommended totally synthetic oil.

Diesel Fuel for Beta Marine Engines

Diesel fuel must conform to EN590 or ASTM D975. The European Standard: EN590 describes the physical properties that all automotive diesel fuel must meet if it is to be sold in the European Union. ASTM International (formerly American Society for Testing and Materials). ASTM D 975 – Standard Specification for Diesel Fuel Oils.

Fuel System – Important!

  • Always fit a fuel/water separator in the fuel supply system. Water in the fuel can seriously damage the injection system.
  • If a fuel supply shutoff valve is fitted do not use a taper tap, only use a ball valve tap. The ball valve type are more reliable and less likely to let air into the fuel system.
  • Be sure to use a strainer when filling the fuel tank. Dirt or sand in the fuel may cause trouble in the fuel injection pump.
  • Always use diesel fuel. Do not use paraffin/kerosene, as this has a low cetane rating and adversely affects the engine.
  • Bio-diesel fuel can be added to the normal diesel fuel up to a maximum limit of 7% without affecting the warranty.
  • Most diesel fuels now contain up to a maximum limit of 7% Biodiesel and this does not affect the engine warranty. The recent changes to fuel specifications allow the addition of FAME (fatty acid methyl ester) biodiesel EN14214:2009, to diesel fuel, but please be aware that biodiesel does allow bacteria to grow more easily in the fuel and this can clog your fuel tank, pipes and filters. If you experience an outbreak of bacterial growth you can either empty and clean out your fuel pipes and tank, or use biocide additives and filtering.
  • Low sulphur diesel fuel – regulations changed recently reducing the sulphur content by 99%, in many countries. The European standard is EN590:2009, and in the USA ASTM D975-09. The engine is designed to run on low sulphur fuel, and this is now preferred.
  • We know that some customers are using Biodiesel fuel, if you use a higher percentage of Biodiesel fuel you must fit an electric lift pump into the fuel supply line, and the fuel filter and oil filter must both be changed together when the oil filter is normally replaced. Important! Beta Marine warranty will not cover fuel equipment when more than 7% Biodiesel is used.
  • Be careful not to let the fuel tank become empty, or air can enter the fuel system, necessitating bleeding before next engine start.
  • The fuel lift pump will only lift fuel through 0.25m. If this is insufficient then an electric fuel lift pump must be fitted. Drawing 202-06421, illustrating recommended wiring for this pump can be supplied upon request.
