1. Composition: Diluting asphalt refers to mixing the original asphalt with solvent to reduce the viscosity of the original asphalt and improve its fluidity and coating property. Marui crude oil belongs to heavy oil, which is mainly composed of high molecular hydrocarbons.

2. Viscosity: Diluted asphalt has low viscosity and is often used in road construction, waterproof engineering and other fields. Marui crude oil has high viscosity and is often used to produce fuel oil, petroleum coke and petrochemical raw materials.
