Castrol CRB Monograde 30 CF is a monograde diesel engine oil designed for use in heavy-duty diesel engines, hydraulic systems and transmissions that specify the use of a monograde diesel engine oil. The SAE 30 viscosity grade is the mid-range selection in the CRB Monograde range, suited to general ambient operating temperatures.
The oil is formulated with cleaning detergents that displace particles which may otherwise build up on engine surfaces, reducing deposit formation, and with anti-oxidants which resist the chemical reactions that lead to oil thickening over the drain interval. It is suitable for engines and equipment that specify a monograde lubricant rather than a multigrade.
Approvals and performance levels include API CF.
Sister grades in the same Castrol CRB Monograde range — Castrol CRB Monograde 10W CF (PRD00002091, PRD00002080) for cooler operating temperatures and Castrol CRB Monograde 40 (PRD00002092) for warmer ambient operation — are also available in our catalogue.
For workshop bulk supply, Castrol CRB Monograde 30 CF is also available in a 208-litre drum (PRD00002092).
Castrol CRB Monograde 30 CF is a diesel engine oil designed for use in heavy duty diesel engines, hydraulic systems and transmissions that specify the use of monograde diesel engine oil. Advantages During its working life, your engine faces challenges from combustion by-products that can form deposits, and thicken the oil. Castrol CRB Monograde 30 CF combats these issues in two ways: It contains cleaning agents which displace particles that may otherwise build up on your engine surfaces reducing deposits. 1. 2. It also contains anti-oxidants which disrupt the chemical reactions that can lead to oil thickening. Castrol CRB Monograde 30 CF provides protection across multiple applications to encourage long and healthy engine life.

A. Castrol CRB Monograde 30 CF is a monograde diesel engine oil — not a multigrade. The SAE 30 viscosity is the single grade specification.
A. Castrol CRB Monograde 30 CF is designed for use in heavy-duty diesel engines, hydraulic systems and transmissions that specify the use of a monograde diesel engine oil.
A. API and ACEA are the universal lubricant performance standards every reputable oil meets. They are your baseline check — match the code your handbook specifies (e.g., API CI-4 or ACEA E7 for heavy-duty diesel) and the oil is technically suitable for your machine. Every oil on our site lists its API and ACEA classifications.
A. Castrol CRB Monograde 30 CF meets API CF, the performance classification for indirect-injected diesel engines.
A. The grade number is the SAE monograde viscosity. CRB Monograde 10W is the cold-side selection, suited to cooler operating temperatures. CRB Monograde 30 CF is a mid-range monograde suited to general ambient operation. CRB Monograde 40 is the warm-side selection. Select according to the equipment manufacturer specification or service manual.
A. Yes, Castrol CRB Monograde 30 CF is designed for use in heavy-duty diesel engines, hydraulic systems and transmissions that specify a monograde diesel engine oil. Check the equipment manufacturer specification before selecting.
A. An OEM Specification is the lubricant requirement set by a vehicle or equipment manufacturer (e.g., MB 228.3, VW 504.00). When an oil lists the code, the oil manufacturer has developed and tested it to meet the criteria the equipment manufacturer requires. Match the code in your handbook and you have a lubricant engineered for your machine.
A. An OEM Approval means the oil has been formally tested and signed off by the equipment manufacturer and listed on their official approved-products register (e.g., MB-Approval 228.3). An Approval confirms the oil is recognised by the equipment manufacturer for service use in their machines.
