What is SAE 1030 oil?

The 10W30 designation on engine oil means that the viscosity of the oil is rated at 10W when an engine is cold and 30 when the engine is hot. This is different than an oil labelled 5W30, which has a thinner viscosity when the engine is cold at 5W.

What is 10W30 oil used for?

10w30 is a multi-grade engine oil ideal for heavy-load engines because of its ability to withstand hot temperatures for a long time without compromising the performance of the engine. This engine oil has a viscosity grade of 10 in low temperatures and 30 in high temperatures.

What is the difference between 1030 and 1040 motor oil?

The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Obviously, a 10W-40 is thicker than a 10W-30 at high temperature. Using the correct viscosity oil eases starting, reduces friction and slows wear.

Which oil is thicker 1030 or 1040?

10W30 and 10W40 engine oils are very similar. While both are low-temperature grade oils, 10W40 is thicker at high temperature; therefore, better to use in warm weather. This article provides tips for using SAE 10W-30 and 10W-40 and covers viscosity grades.

When did OE start using 10W30 oil in cars?

Older engines were built with much looser tolerances, which allowed oils such as 10W30 to be commonplace as an OE recommended oil in the 1990’s and before.

What is the viscosity rating of 10W30 oil?

10 is the cold weather viscosity rating for 10W30. This number represents an oil’s ability to maintain its resistance to hardening and thickening at 0 degrees Celsius. The lower the number, the thinner the oil.

What kind of oil is in Castrol 10W 30?
