Learn the truth behind common car maintenance myths. This article debunks misconceptions about oil changes, warming up vehicles, brake fluid, tuning, filters, cooling systems, and air conditioning, providing practical tips for smarter vehicle upkeep and savings.
• Oil changes every 3,000 miles: Refer to your owner’s manual instead of adhering to generic intervals suggested by oil brands. Many vehicles can go 7,500 miles or more between oil changes under normal driving conditions.
Changing your oil at recommended intervals will protect your engine, but extending the interval is often safe.
• Warming up your car before driving: Modern engines warm quickly, so lengthy pre-start warm-up routines are unnecessary and may waste fuel.
• Brake fluid needs frequent replacement: Brake fluid primarily lubricates brake components and typically only requires replacement every one or two years, per your vehicle's manual.
• Engine tuning: Routine tune-ups promote engine health but are generally recommended every 30,000 miles, not more often.
• Filter replacements: Oil, air, fuel, and transmission filters have varying lifespans; consult your manual or mechanic for precise guidance.
• Cooling system upkeep: Modern vehicles feature sealed cooling systems, with coolant lasting up to two years or longer, reducing the need for frequent flushes.
• Driving with windows open vs. using AC: Running the AC consumes more fuel, but open windows increase aerodynamic drag, which can be equally or more inefficient on fuel consumption.
