Grease Oil
SAE 40 and SAE 50 are monograde oils classified under the SAE (Society of Automotive Engineers) standard. These grades are primarily used in heavy-duty diesel engines, industrial machinery, and high-temperature operating environments, offering reliable protection and consistent lubrication performance.
Feature | SAE 40 | SAE 50 |
Viscosity | Medium | Top |
Operating Temperature | Suitable for high temperatures | Suitable for very high temperatures |
Engine Type | Light to medium diesel | Heavy diesel, road construction machinery |
Lubrication at Cold Start | Weaker | Weaker |
Fuel Consumption | A little more | More than SAE 40 |
Note:
These oils perform poorly at low temperatures, so they are not recommended for cold climates or for cold starts. Today, multigrade oils such as 15W40 or 20W50 are a good alternative to these grades, as they perform better at different temperatures.
🧪 What is SCC engine oil?
SCC oil is usually an abbreviation for phrases such as Super Clean Crankcase or, in some brands, is used as a trade name for oils specifically for heavy-duty diesel engines. These oils usually have the following characteristics:
Suitable for turbocharged and non-turbocharged diesel engines
Contain anti-wear, anti-corrosion and cleaning additives
Mineral or semi-synthetic base
Has API standards such as CF, CH-4 or CI-4
Some companies use the term SCC for oils that are specifically for industrial engines, generators, ships or road construction machinery. These oils are usually produced in SAE 40 or SAE 50 grades and are designed for harsh operating conditions.
✅ Important points when choosing engine oil
Climate conditions: In hot regions, high-viscosity oils such as SAE 50 perform better.
Engine type: Heavy-duty diesel engines require oils with high pressure resistance.
Quality standards: Pay attention to API, ACEA and viscosity level.
Oil change interval: Oils with more additives usually have a longer life.
