That means the oil is 15 weight when cold and 40 weight when hot. The higher the number the thicker the 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.
15W-40 15W-40
15w 40 is recommended for this size engine. 10w 40 will suffice if no 15w is available.
15w 40 engine oil can be used for all temperatures down to -15 deg centergrade !
No
15w-40
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.
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.
If it is a diesel then it holds 4 quarts. I would recommend you use any of these major brands. Mobil Delvac 1300 Super 15w-40 weight, Shell Rotella T 15W-40, or Chevron Delo 400LE 15W-40 weight.
This should be fine, although in very cold weather you might have a little more difficulty starting the engine because 15W 40 oil is thicker than 10W 40.

10w/40 or 15w/40 should do the trick.
