Scotty Kilmer’s simple tips to improve fuel efficiency for free

Learn Scotty Kilmer’s easy ways to boost fuel economy without extra costs, including tire pressure, air filter, and oil changes for better mileage.
Automotive mechanic Scotty Kilmer, who has previously voiced concerns about TPMS system hacks and location tracking, shares simple ways to improve fuel efficiency without extra costs. He emphasizes that regular vehicle maintenance plays a crucial role.Tire pressure is a key factor. Underinflated tires increase rolling resistance, directly leading to higher fuel consumption. It’s recommended to check pressure at least once a month, doing so when the tires are cold.The engine air filter also matters. A dirty filter restricts airflow, causing the engine to work harder and use more fuel. Replacing the filter is quick and doesn’t require complex tools.Kilmer advises regularly changing the engine oil and oil filter. Using the right oil reduces internal friction, which benefits both fuel economy and engine longevity.Coolant importance is highlighted separately. Contaminated antifreeze can cause sensor malfunctions and increased fuel consumption. Changing the fluid every 2–3 years is recommended.Other tips include using Eco mode, keeping windows closed while driving, and adhering to speed limits. These suggestions help cut operating expenses.
