Diesel engine oil pressure generally ranges from 3 to 5 bars. Engine oil serves multiple functions such as lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. Base oil is the primary component of lubricants, determining their fundamental properties. Additives are used to compensate for and enhance the performance shortcomings of the base oil, imparting new characteristics, making them an essential part of lubricants. Taking the Great Wall Cannon diesel engine as an example: this vehicle measures 5410mm in length, 1934mm in width, and 1886mm in height, with a wheelbase of 3230mm. It is a 4-door, 5-seat pickup truck with an 8-speed automatic transmission.

Can Duster Wax Be Sprayed Directly on the Car?

Duster wax can generally be sprayed directly on the car, but the owner needs to apply to the vehicle management office at the registration location. Below is an introduction to duster wax: 1. Introduction: Spraying duster wax on a car duster can effectively absorb floating dust and also provides a certain waxing and polishing effect on the car's paint. 2. Method: It is best not to wet the car duster before use, as most of the dust on the car body is dry. A dry car duster can easily sweep away the dust. The method involves evenly spraying the duster wax on the duster, making it slightly damp. You can wait for a while to allow the duster to fully absorb the wax, which will make it more effective in collecting dust. 3. Follow-up: After dusting the car body, there may be excess wax remaining, which should be wiped clean with a dry cloth to avoid unnecessary trouble. However, it is also important to maintain the duster's moisture level. The cleaning process should be carried out from the roof to the body, proceeding from top to bottom.

Definition of fuel consumption per 100 kilometers: Fuel consumption per 100 kilometers refers to the amount of fuel a car consumes when driving 100 kilometers on the road at a certain speed. It is a theoretical indicator for vehicles. The fuel consumption per 100 kilometers is a value measured by manufacturers under controlled conditions using a dynamometer installed on the vehicle's chassis. This value is then converted into speed parameters, and the theoretical experimental fuel consumption data per 100 kilometers is calculated by driving at specified speeds.
