Towing more than your car can handle is like sprinting with a backpack full of rocks.
Why it matters?
Excess weight strains the engine, transmission, brakes, and suspension.
Avoid This By:
- Not exceeding the GVWR (Gross Vehicle Weight Rating).
- Removing unnecessary cargo from the trunk.
- Using the correct trailer/towing equipment.
Pro Tip: Overloaded cars also get worse gas mileage and are harder to control at speed.
14. Use the Right Type of Oil and Coolant
Not all fluids are created equal—and using the wrong one can wreck your engine.
Why it matters?
Different engines require specific formulations of oil and coolant to function properly.
How to Get It Right:
- Check the user manual for specs (e.g., 5W-30 synthetic).
- Avoid “universal” coolants unless they list OEM compatibility.
- Always match DOT ratings for coolant types (e.g., HOAT, OAT, IAT).
Fact: Mixing coolant types can create a jelly-like substance that blocks flow and causes overheating.
15. Park Your Car in the Right Environment
Where you leave your car affects how your engine ages.
Why it matters?
Exposure to harsh weather (extreme sun, snow, humidity) can damage seals, belts, and fluids.
