Maintaining a car does not have to be expensive to be effective. Small strategic investments, often around $20 or less, can save money, prevent bigger repair costs, extend a vehicle’s lifespan and even increase resale value.

From routine upkeep to smart gadgets, these affordable car expenses deliver measurable benefits and make daily driving safer and more efficient. Prices may vary depending on location, but all of these items can generally be purchased for $20 or less.

Car Wash and Detailing

• Cost: $15 to $20 per session

Regular cleaning protects paint and interior surfaces from dirt, corrosion and road salt that can cause rust. A monthly wash preserves appearance and resale value while helping spot minor issues before they become costly. Delta Sonic Car Wash reported that routine cleaning, especially in winter, removes salt and grime that damage your car’s undercarriage and paint. Hand washing at home can provide the same protection at little cost.

Portable Tire Inflator

• Cost: $15 to $20

AutoTools Depot reports that maintaining proper tire pressure improves fuel efficiency, extends tire life and enhances safety. A portable inflator makes it easy to keep tires at the correct pressure on the go, reducing the risk of flats or blowouts and eliminating the need for roadside assistance.

Fuel System Cleaner

• Cost: $15 to $20

Fuel system cleaners keep engines running efficiently by removing deposits from injectors, carburetors and other components. Complete system formulas tackle multiple parts, while injector-specific products focus on precision cleaning. Sonora Ford reports that regular use improves fuel efficiency, maintains performance and helps prevent costly repairs, making it a smart, low-cost investment.

Windshield Wiper Blades

• Cost: $15 to $20

According to the National Highway Traffic Safety Administration, maintaining properly functioning wipers is crucial for safe driving, as they are essential for clearing rain, snow and debris from the windshield, thereby enhancing visibility and reducing the likelihood of accidents.

Emergency Supplies

• Cost: $10 to $20

A basic kit with an LED flashlight, jumper cables and reflective triangles can prevent costly towing or repair services. The American Automobile Association recommends keeping a well-stocked emergency kit in every vehicle to improve safety and preparedness on the road.

Tire Pressure Gauge

• Cost: $15 to $20

Properly inflated tires improve fuel efficiency, extend tire life and enhance safety. Underinflated tires reduce gas mileage, wear out faster and pose safety risks. An Oak Ridge National Laboratory study found that vehicles running on tires at 75% of the recommended pressure lose 2-3% in fuel economy, while tires at 50% waste up to 10% more fuel. 

Air Filter Replacement

• Cost: $15 to $20

A clean air filter improves engine performance and fuel efficiency. Replacing a clogged filter reduces fuel costs, prevents engine wear and maintains consistent horsepower, making it a low-cost way to protect the car’s heart. According to the Car Care Council, routinely changing the air filter is a simple, low-cost way to protect engine health and optimize vehicle efficiency 

Battery Terminal Cleaner or Protective Spray

• Cost: $10 to $20

The Interstate Batteries recommends keeping battery terminals clean to prevent corrosion, which can cause starting issues and reduce battery lifespan. A terminal cleaner or protective spray keeps connections reliable and helps avoid early replacements. For a DIY option, mix baking soda and distilled water and gently scrub away blue-green corrosion.

Microfiber Cleaning Cloths

• Cost: $10 to $20

Microfiber cloths lift dirt and spills without scratching or streaking, keeping your car looking newer. A small set pays for itself over time by replacing disposable towels. Wirecutter testing shows some cloths clean slightly better, making quality worth considering.

Pocket Vac Rechargeable Handheld Vacuum With Accessories

• Cost: $20 or less

A compact, cordless vacuum that removes dirt and crumbs from upholstery, carpets and tight spaces. Available at Walmart, it comes with multiple attachments and a reusable HEPA filter, helping maintain a clean car interior between professional detailing sessions and paying for itself by reducing the need for costly cleanings.
