The engine uses 10W30 oil and the pump uses 30W oil.
10W30 Oil: This means that the viscosity of the oil is rated at 10W when an engine is cold and 30 when the engine is hot.
30W Oil: This is a single grade oil with a viscosity rating of 30. It's called a single grade (or monograde) oil because it only has one viscosity grade. This is different from a multi grade oil, like 10W-30, which is rated for both SAE 10W and SAE 30.
W stands for weight.
