Your official resource for frequently asked questions related to Heavy Duty Engine Oil (HDEO) and other diesel oil questions that are answered by the experts within our Shell technical team.
Is it OK to use 10W30 instead of 15W40?
Since 10W-30 is thinner than 15W-40, its film strength can be weaker and it can be more prone to oxidation. Therefore, high quality additives are needed to compensate for those weaknesses in order for 10W-30 to protect as well and last as long as 15W-40.
What is the viscosity of 10W 30?
Viscosities and densities of SAE Grade oils.
| SAE Multigrade | Viscosity | |
|---|---|---|
| Centistokes | 10-6 reyns (lb s/in2) | |
| 10W-30 | 69 | 8.8 |
| 10W-40 | 94 | 11.9 |
| 20W-50 | 166 | 21.3 |
Is 10W30 for diesel?
Mobil Delvac™ Extreme 10W-30 is a synthetic, high-performance diesel engine oil that helps extend engine life while providing long drain capability for modern diesel engines operating in extreme conditions.
Which is better 10w30 or 15W-40?
High quality 10W-30 oils can perform as well, and better than industry-standard 15W-40 oils. The stated viscosity of a HDEO does not represent an exact viscosity, but rather a viscosity within a range on the SAE viscosity scale.
Can you use 15W-40 as hydraulic oil?
Mobil Agri Super™ 15W-40 is a high performance, multi-functional lubricant for most farm equipment applications. This STOU lubricant provides good performance in diesel and gasoline engines, transmissions, hydraulics, final drives and oil-immersed brakes operating in agricultural service.
What does 10W30 stand for?
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?
What is 10w30? 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 10W-30 used for?
What does 10W-30 stand for?
What is 10W 30 oil used for?
Are all 10W 30 oil the same?
NOT ALL 10W-30 ENGINE OIL IS THE SAME VISCOSITY Engine Oil viscosity is measured in centistokes (cST) at 100°C. “W’ grades are measured at 40°C. 10W-30 engine oils can fit anywhere in the range of 9.30cST to 12.49cST.
