Methods for breaking in a car after major overhaul: 1. Avoid high speeds: The overhauled engine will have speed restrictions, try to maintain a speed below 80 km/h; 2. Avoid emergency braking: Emergency braking not only shocks the braking system during break-in but also increases the impact load on the chassis and engine. Do not perform emergency braking within 300 km after the overhaul; 3. Pay attention to oil maintenance: Use high-quality, high-cleanliness engine oil for the car, and do not use oil below the manufacturer's specified grade. Avoid adding oils with anti-wear additives or various other additives to prevent further engine damage; 4. Coolant check: After the engine overhaul, regularly check the coolant level. Insufficient coolant can cause engine overheating and wear; 5. Warm-up before starting: Warm up the engine before starting. Warming up is actually giving the engine enough time to lubricate, especially for turbocharged models, which must be warmed up before starting, and the lubrication time should be at least one minute.

What is the actual fuel consumption of the Changan CS75 Plus 2.0T?

The actual fuel consumption of the Changan CS75 Plus 2.0T is 11.2L/100km. There are three methods to reduce vehicle fuel consumption: Minimize vehicle weight: Keep the interior as simple as possible and avoid carrying unnecessary items. For every additional 1kg of load, the vehicle's fuel consumption increases by 1%; Avoid excessive modifications: Adding spoilers, protective covers, or wings can disrupt the original aerodynamic design, increasing wind resistance and consuming extra fuel. Modifying lighting systems increases electrical load, leading to unnecessary fuel consumption; Develop good driving habits: Avoid sudden acceleration, driving at high speeds in low gears, prolonged idling, frequent lane changes, or braking. Aim for smooth starts, steady-speed driving, and reduced braking.

Is there a way to solve the problem of the Outlander's seats being too hard?

The solution to the Outlander's seats being too hard is to add a seat cushion. There are two types of seats: Leather seats: Easy to clean. Compared to fabric-covered seats, dust only settles on the surface of leather seats and does not penetrate deep into the seat, so a simple wipe with a cloth can complete the cleaning.

Leather: The surface is fine and soft to the touch, with almost no visible pores. It is sturdy yet very flexible, making the seats produced extremely aesthetically pleasing. It is the most commonly used material for all automotive leather seats.
