That means the oil is 15 weight when cold and 40 weight when hot. The higher the number the thicker the oil.

What is Difference between 15w-30 and 15w-40 oil?

15w means they are the viscosity (flow) when the oil is cold, the -30 and -40 is the viscosity of the oil when hot. Therefore the 15w-30 being the lower Viscosity means it will flow fast then the 15w-40 when the oil is hot.

Can you mix 5w 30 with 15w 40?

Yes, you can mix 5W-30 and 15W-40 motor oils, as they are both compatible in terms of base oil and additives. However, mixing oils with different viscosities can result in a final product that doesn't provide optimal protection or performance, especially in extreme temperatures. It's generally best to stick to one viscosity grade for consistent performance, as specified by your vehicle's manufacturer.

What oil can be substituted for Lucas 15W40?

You can substitute Lucas 15W-40 with any high-quality diesel engine oil that meets or exceeds the API CI-4, CJ-4, or CK-4 specifications. Common alternatives include Shell Rotella T4 15W-40 or Mobil Delvac 15W-40. Additionally, you could use other multi-viscosity oils like 10W-30 or 20W-50, depending on the temperature range and manufacturer's recommendations for your specific engine. Always ensure that the substitute oil is compatible with your engine's requirements.


Can you use 10w- 40 oil in a pressure washer that is supposed to take 15w-30?

Using 10W-40 oil in a pressure washer designed for 15W-30 can be acceptable in certain conditions, as both oils have similar viscosity ranges. However, 10W-40 is thicker at higher temperatures compared to 15W-30, which may affect performance and lubrication. It's best to consult the owner's manual for specific recommendations, as using the wrong oil can lead to engine damage or reduced efficiency. If in doubt, stick with the recommended oil for optimal performance.


Can you use 15w40 oil instead of 20w40 in diesel engine?

Yes, you can use 15W-40 oil instead of 20W-40 in a diesel engine, as both oils have similar viscosity characteristics at operating temperatures. However, the lower viscosity at cold temperatures in 15W-40 may provide better cold start performance in cooler climates. Always check the engine manufacturer’s recommendations to ensure compatibility and optimal performance.
