For Kubota Based Propulsion Engines, Beta Marine Recommend:

Engine Oil

Engine oil quality should have the minimum properties of the American Petroleum Institute “API” classification CF with multi-grade SAE ratings as listed in the following table.

NB: An acceptable alternative is a mineral based, semi-synthetic lubricating oil with a content mix no greater than 30% being synthetic based. Do not mix two different types of oil or SAE rating.

Do not use lubricant additives and/or fully synthetic lubricating oil.

Ambient Temperature Multi-Grade Oil

Ambient TemperatureMulti-Grade Oil
-30°C to 0°CSAE 10W/30
-15°C to +15°CSAE 15W/40
0°C to +30°CSAE 15W/40
25°C and aboveSAE 15W/40

Engine Coolant Antifreeze

Always use a Mono Ethylene Glycol Based Extended Life Anti-freeze mixed 30 < 50% with water.

NB: Do not exceed an Anti-freeze mix greater than 50%, as the engine cooling efficiency will be detrimentally affected.

For engine coolant capacity please refer to the relevant engine operator’s handbook. PDF’s can be found within the relevant engine page within this website.

Transmission Lubricants

Depending on the transmission brand/type they will either require Automatic Transmission Fluid or Engine Oil. For type, specification and capacity, please refer to the relevant transmission operator’s handbook. PDF’s can be found within the relevant engine page within this website.
