sae,15w,–40,意思具体解释如下 ： SAE：代表油品的黏度等级。 15W：低温流动性，W代表冬季使用的机油，数值越小说明适应低温能力越好。

SAE 15W-40 refers to a multigrade lubricant. On this type of lubricant you’ll see two numbers separated by a hyphen. One of the numbers is followed by a W, which refers to “winter” and indicates the viscosity grade in cold temperatures. An oil with a low SAE W number will flow better, have better cold starts, and lower engine wear.

2012年9月8日 · Delo 400 SDE SAE 15W-40 with ISOSYN Advanced Technology is an API CK-4 heavy duty engine oil specifically formulated for 2017 greenhouse gas (GHG 17) compliant diesel engines designed to meet lower CO2 emissions and improved fuel economy, in addition to EPA 2010 compliant low emission diesel engines with Selective Catalytic Reduction (SCR ...

2023年7月12日 · 15W代表了冷启动时的低温黏度，W表示冬季（Winter），数字15意味着在低温下油的流动性仍然较好。 40代表了高温下的黏度，表示在高温条件下，油的流动性仍然保持稳定。 - (R-32)：这部分标识符可能与制冷剂R-32有关，但在润滑油标识中并不常见。 R-32通常是指一种用于空调和制冷系统的制冷剂。

2006年5月1日 · SAE 15W-40. This oil has a weight of SAE 15W-40, meaning it has an SAE viscosity rating of 15 in cold temperatures and a rating of 40 at normal operating temperature. Always check your vehicle's owner's manual to verify that this is the correct weight of motor oil for your vehicle. Conventional Motor Oil

2023年6月1日 · SAE 40 is more viscous and it needs more energy to move it. But, it provides less fuel economy. On the other hand, 15W40 is less viscous than SAE 40 and provides better fuel economy as less energy is needed to move it. it results in a lower drag on the engine due to reduced friction.

In this comprehensive guide, we’ll delve into the intricate details of SAE 40 and 15W-40 engine oils, exploring their formulations, characteristics, applications, advantages, and considerations. By the end, you’ll be well-equipped with the knowledge needed to make an informed decision based on your vehicle’s requirements.

This 4-cycle engine oil is recommended for naturally aspirated and turbocharged 4-stroke diesel engines and 4-stroke gasoline engines in which the API CK-4 or SN service category and SAE 15W-40 viscosity grade are recommended. 15W-40 diesel engine oil is also backwards compatible with diesel engines in which the API CJ-4, CI-4, CI-4 Plus and CH ...
