What are the 8 fuel-saving methods for older cars?

[DiSavannah]

The 8 fuel-saving methods for older cars include minimizing brake usage, reducing throttle input, and coasting in neutral at higher speeds. Below are precautions regarding automobile engine usage: 1. Avoid coasting in neutral: The engine inherently features fuel-cut during deceleration, making neutral gear counterproductive for fuel economy. 2. Maintain vigilant observation during vehicle operation: If oil stains are detected on the ground, promptly assess whether engine oil leakage has occurred and consult with the authorized 4S dealership to eliminate potential safety hazards. 3. Avoid immediate engine shutdown: For turbocharged vehicles, refrain from turning off the engine immediately after high-speed driving or hill climbing. Allow 10 minutes of idling before shutdown, as turbocharged engines accumulate carbon deposits several times faster than naturally aspirated engines. 4. Replace or filter brake fluid: When brake fluid becomes contaminated with water or contains visible impurities/sediment, promptly replace or thoroughly filter it to prevent insufficient braking pressure that may compromise braking performance.
