The Software Glitch That Made Gas Free

Some People Will Try Anything To Save On Gas

Imagine if every time you swiped your fuel rewards card, your gas pump just handed you free fuel. Sounds like a dream come true, right? Well, it happened—at least for one Nebraska woman. Over roughly six to seven months, she exploited a software glitch that let her pump an estimated 7,400 gallons of gas without paying a dime. The total free fuel came to nearly $27,000–$28,000, until, predictably, the law caught up with her. While her double-swiping stunt might seem like the ultimate hack for free gas, it ended with felony theft charges—a cautionary tale that’s as wild as it is funny.

DIY Fuel-Saving Contraptions: Genius or Gimmick?

Acetone Anecdotes

Some folks claim that adding  acetone to gasoline will magically boost your mileage by improving vaporization and even cleaning the injectors. Sounds promising, doesn’t it?

The Reality?

  • No Proven Mileage Gains: Multiple tests have debunked this myth, and modern gasoline already contains optimized additives.

  • Risk of Damage: Acetone is a strong solvent that can degrade plastic and rubber components in your fuel system—leading to costly repairs.

  • Old-School Advice: While this trick circulates as “old wisdom,” today’s engines aren’t built for such alterations.

Adding acetone might sound like a DIY miracle, but it’s more likely to harm your engine than help your wallet.

The Fuel Doctor FD-47 Fiasco

Ever heard of the Fuel Doctor FD-47? This little gadget plugs into your car’s cigarette lighter and promises to “condition” your vehicle’s power supply, boosting your miles per gallon by up to 25%.

The Reality?

  • Nothing More Than LEDs: Disassembly shows it’s essentially just a circuit board with LED lights—no secret fuel conditioning happening.

  • Inconsistent Results: In rare cases, users have seen minimal improvements (if any), but nothing that justifies the cost.

  • Overhyped: The FD-47 is more flash than substance, and independent reviews consistently dismiss its claims.

The Fuel Doctor is more hype than help—its only effect might be lighting up your dashboard, not your fuel savings.

HHO (Water Fuel) Kits

Then there are the HHO kits, which claim to use your car’s alternator to power an electrolytic cell that splits water into hydrogen and oxygen. The idea is that the resulting “HHO” gas, when fed into the engine, helps boost combustion and, consequently, fuel efficiency.

The Reality?

  • Energy Losses Galore: Electrolysis requires more energy than the hydrogen’s combustion can replace. In short, you’re burning more fuel to make the gas than you save by using it.

  • Potential Engine Risks: Introducing extra hydrogen without proper engine calibration can lead to misfires or even damage over time.

  • Debunked Claims: Multiple tests and expert reviews have shown that these kits don’t deliver any meaningful fuel economy gains.

HHO kits might sound like a sci-fi solution, but they’re a net loss for your wallet—and your engine.

Magnetic Fuel Savers

Magnetic fuel savers are perhaps the most common of all “miracle” devices. They claim that by attaching a magnet to your fuel line, the device can realign the fuel molecules so they burn more efficiently.

The Reality?

  • No Scientific Basis: Fuel (a non-polar liquid) simply doesn’t respond to magnetic fields in the way proponents claim.

  • Ineffective at Best: Studies and tests consistently show no measurable improvement in fuel economy when using these magnets.

  • Risky Misconception: Relying on magnets for fuel savings can distract from proven methods like regular maintenance and smart driving habits.

While it might be tempting to clip on a magnet and hope for a miracle, scientific testing has repeatedly shown that magnetic fuel savers don’t deliver any real benefits.

A Word of Caution

It might be tempting to try every trick in the book—from double-swiping a rewards card to mixing strange additives into your gas—but the risks far outweigh any potential rewards. Not only can these methods damage your vehicle, but they could also land you in legal or financial trouble. Real savings come from proper vehicle maintenance, fuel-efficient driving habits, and, of course, smart choices when buying your car.

Some shortcuts might be entertaining to hear about, but remember: the only free gas you should be getting is from a well-oiled deal—one that comes with genuine savings and honest service.

Ready for Genuine Savings?

While these wild schemes make for entertaining stories, the only smart move is to invest in a vehicle that’s built to save you money mile after mile. Instead of risking engine damage or legal woes by trying dubious contraptions, why not choose a ride that’s engineered for reliability and efficiency?

April Showers Bring Flowers And Wet Roads

Essential Tire Care Tips for Rainy Weather

Spring is here, and while we enjoy the blooming flowers and warmer temperatures, the rainy season can make driving a challenge. At First Class Auto Sales, we want you to stay safe and confident on the road, no matter the weather. Here are some essential tire care tips to help you navigate wet roads safely:


Tire Check

  • Tread Depth: Ensure your tires have at least 3/16 inches of tread depth. Deeper grooves channel water away, improving grip on wet roads. Don’t rely solely on the "penny test," as tire wear may not be uniform. Visually inspect for cracks, bulges, or uneven wear—signs that your tires might need immediate replacement.


Tire Maintenance

  • Proper Inflation: Keep your tires inflated to the recommended pressure found in your owner’s manual or on the driver’s door jamb sticker. Underinflated tires reduce traction and fuel efficiency, especially in wet conditions. Check your tire pressure at least once a month and before long trips.

  • Tire Rotation: Rotate your tires regularly, typically every 5,000 to 6,000 miles, as recommended by your vehicle’s manufacturer. This prevents uneven wear and extends the life of your tires.


Additional Tips

  • Invest in All-Season Tires: If you live in an area with varied weather, all-season tires offer a balanced performance for rain, light snow, and dry roads.

  • Expert Advice: At First Class Auto Sales, our team is here to help! Whether you need tire recommendations or guidance on vehicle maintenance, we’re just a call or visit away.


Drive Safe This Spring

Even with the best precautions, rainy weather can be unpredictable. Prioritize safety by maintaining your tires and driving cautiously during downpours. If your current vehicle isn’t keeping up with your needs, it might be time to upgrade to something safer and more reliable.

At First Class Auto Sales, we offer a wide selection of vehicles equipped to handle all seasons—and we make it easy for anyone to drive away with buy here pay here financing, bad credit car loans, and zero-down payment options.

I Can See Clearly Now The Fog Is Gone

The Safe Way to Defog Your Windshield

Driving with a clear windshield isn’t just convenient—it’s critical for safety. A fogged-up windshield can turn a simple drive into a dangerous situation, reducing your ability to react to road hazards and increasing the risk of accidents. At First Class Auto Sales, we care about your safety and want to help you stay prepared for any driving condition.

Here’s a guide to understanding windshield fog and practical tips to keep your view crystal clear, whether you’re starting your morning commute or heading home on a humid evening.


Why Windshields Fog Up

  • The Science: Fog forms when warm, moist air inside your car meets the cold surface of your windshield, creating condensation.

  • The Risks: Reduced visibility makes it harder to see pedestrians, vehicles, and road signs. Driving with a fogged windshield is dangerous for you and everyone around you.


Preventative Measures

Stop fog before it starts with these simple tips:

  • Ventilate Your Vehicle: Leave windows slightly open overnight to balance inside and outside temperatures.

  • Check Cabin Air Filters: Clean filters ensure proper airflow and help prevent fog.

  • Pre-Emptive Climate Control: Switch to fresh air mode before parking to reduce moisture build-up.

  • Maintain Your HVAC System: Regularly service your heating and air conditioning systems to keep them efficient.


Defogging Techniques for Safety

If your windshield fogs up, use these steps to clear it quickly and safely:

  1. Start Your Engine: Begin the defrost cycle as soon as you start your car.

  2. Engage the Defroster: Warm the windshield to evaporate condensation.

  3. Use the A/C: Activate air conditioning to dehumidify the cabin.

  4. Turn Off Recirculation: Let in dry outside air to reduce moisture.

  5. Crack the Windows: Slightly open windows to balance the interior and exterior temperatures.

  6. Use Wipers: Clear external condensation with your windshield wipers.

  7. Manual Cleaning: Use a clean microfiber cloth to wipe the glass if needed.

Safety First: Never drive with obstructed visibility. If the fog persists, pull over until it clears.


Choosing the Right Products

Using the right tools and products can make defogging more effective:

  • Anti-Fog Solutions: Apply products like Rain-X Anti-Fog or Stoner Invisible Glass Anti-Fog to prevent condensation.

  • Glass Cleaners: Use automotive-grade cleaners that don’t leave streaks or residues.

  • Microfiber Cloths: Keep a lint-free microfiber cloth in your car for quick and easy cleaning.

Important Tip: Test any product on a small section of the windshield first, especially if your vehicle has sensors or cameras for advanced driver-assistance systems (ADAS).

6 Costly Car Repairs That Are Totally Avoidable

Simple Mistakes That Can Lead to Big Repair Bills

Owning a car is a significant financial responsibility. Beyond the purchase price, there’s insurance, fuel, and maintenance to consider. While some repairs are inevitable, others can be avoided entirely with proper care and attention.

At First Class Auto Sales, we’re here to help you get the most out of your vehicle and avoid costly mistakes. Here are six preventable car repairs that can save you time, money, and stress:


1. Never Ignore the Check Engine Light

That little light on your dashboard isn’t just for show. Ignoring the check engine light can lead to severe engine damage that could have been prevented.

  • Common Causes: Loose gas cap, bad oxygen sensor, or a failed catalytic converter.

  • The Fix: Address the issue as soon as the light comes on to avoid larger, more expensive problems down the road.


2. Replace the Battery When Needed

A failing battery can cause numerous electrical issues and strain your vehicle’s alternator and starter.

  • Battery Lifespan: Most batteries last 3–5 years.

  • Signs of a Failing Battery: Slow engine start, dimming lights, or electrical system glitches.

  • The Fix: Replace your battery on schedule to prevent unnecessary wear on other components.


3. Maintain Proper Fuel Levels

Running your car on low fuel can damage the fuel pump and lead to clogged filters.

  • The Risk: Debris from the bottom of the tank can clog the fuel filter, reducing engine performance.

  • Pro Tip: Keep your fuel tank at least a quarter full to avoid premature fuel pump failure. Gasoline helps cool the pump, extending its lifespan.


4. Rethink Unnecessary Transmission Flushes

While transmission flushes are part of routine maintenance, they can sometimes cause issues in older vehicles with unknown maintenance histories.

  • The Issue: New fluid can dislodge debris, potentially clogging filters and causing transmission problems.

  • The Fix: Consult a trusted mechanic or service team (like ours at First Class Auto Sales) before flushing the transmission.


5. Use the Correct Tire Size

Driving with mismatched or improper tires can cause significant mechanical issues, especially with your vehicle’s differential.

  • The Risk: Mismatched tire sizes can trick your car’s differential into thinking the smaller tires are slipping, leading to unnecessary wear or failure.

  • The Fix: Always use tires rated for your vehicle, and only rely on your spare tire for emergencies.


6. Don’t Kick Ice and Sludge Off Your Car

It may be tempting to kick ice or snow off your car during the winter, but this habit can cause cracks or damage to plastic moldings and bumpers.

  • Why It Happens: Cold temperatures make plastic brittle, increasing the likelihood of cracking.

  • The Fix: Instead of kicking, use a soft brush or warm water at a car wash to remove debris safely.


Stay Ahead with Preventative Maintenance

At First Class Auto Sales, we believe in helping our customers save money by preventing costly repairs. Regular maintenance and smart driving habits can extend the life of your car and keep it running smoothly.

Why Choose First Class Auto Sales?

  • Reliable Vehicles: Our inventory includes cars, trucks, and SUVs that are built to last.

  • Flexible Financing: With buy here pay here financing and bad credit car loans, we make it easy for anyone to drive away in a dependable vehicle.

  • Expert Support: Our team is here to answer your questions and guide you toward smarter car ownership.

Road Trip Anyone

You Might Go on Vacation, But Car Maintenance Never Should

As the dog days of summer roll around, family vacations and road trips take center stage. While it’s great to take a break from your regular routine, one thing that shouldn’t go on vacation is your car’s maintenance. At First Class Auto Sales, we care about your safety and your ride—so here’s how to get road-trip ready while keeping your car in top shape.


Getting Prepared to Go

Before you hit the open road, take some time to check your car. Here’s a quick checklist:

  • Engine Oil: Make sure your oil is at the correct level and not overdue for a change.

  • Coolant Levels: Keep your engine from overheating in the summer heat.

  • Tires: Check for proper inflation, tread depth, and any visible damage.

  • Brakes: Listen for squeaks or grinding and ensure they’re in good working order.

Not comfortable doing this yourself? Bring your car to a trusted professional for a thorough inspection. At First Class Auto Sales, we’ll help ensure your vehicle is road-trip ready.


Don’t Sweat—or Let the Small Things Bug You

Summer driving can throw some curveballs, so it’s a good idea to check these often-overlooked items:

  • Air Conditioning: A functioning A/C is a must in the summer heat.

  • Wiper Blades and Washer Fluid: Sudden downpours or bug splatters can obstruct your view, so make sure these are in good condition.

Being prepared for the little things can make all the difference in enjoying your trip.


Always Have a Backup Plan

Modern technology is great, but it’s not foolproof. What happens if you’re driving in an unfamiliar area and lose GPS signal or your phone dies?

  • Carry a Physical Map: It might seem old-fashioned, but it’s a lifesaver when technology fails.

  • Share Your Plans: Let someone know your route and estimated time of arrival. This way, help knows where to find you if something goes wrong.

Don’t forget to pack an emergency kit with essentials like water, snacks, a flashlight, and basic tools—it’s always better to be prepared.


Stay Safe on the Road

Driving in the summer heat comes with its own challenges, so remember to:

  • Stay Hydrated: Drink plenty of water to avoid heat exhaustion.

  • Take Breaks: Stop every couple of hours to stretch and stay alert.

Most importantly, enjoy your trip and make the most of your summer adventures!


Upgrade Your Ride for the Journey

If your current vehicle isn’t ready for a long road trip, it might be time for an upgrade. At First Class Auto Sales, we offer:

  • Reliable Pre-Owned Vehicles: Perfect for road trips and everyday driving.

  • Flexible Financing Options: Including buy here pay here financing and bad credit car loans to make your next car affordable.

  • Expert Support: Our team is here to guide you every step of the way.

How To Clean Your Car - It's All In The Details!

Top Hacks to Refresh Your Ride Inside and Out

Does your car feel a little worse for wear? Faded upholstery, streaky windows, and dull headlights can make even the best vehicles seem tired. But there’s good news—you don’t have to spend a fortune on professional detailing to bring back that like-new shine. With a few simple hacks, you can clean your car inside and out, all while saving money!

At First Class Auto Sales, we love helping drivers keep their cars in top shape. Here are some tried-and-true tips to clean your car and keep it looking great.


How to Clean and Restore Your Headlights

Cloudy headlights don’t just look bad—they can reduce visibility and make driving at night more dangerous. Here’s an easy DIY method for restoring clarity:

  1. Wash and Sand Horizontally: Clean the headlights with warm, soapy water. Mask the surrounding area to avoid scratches, then wet sand the lens using progressively finer sandpaper (start with 1,000 grit and finish with 2,500 grit).

  2. Rinse and Sand Vertically: Rinse, then sand in the opposite direction to smooth the surface.

  3. Buff with Polish: Apply polishing compound with a soft cloth and work in circular motions until the lens is clear.

  4. Final Polish: Buff off residue with a clean cloth, re-polish any remaining foggy areas, and enjoy crystal-clear headlights!

Pro Tip: Wash your headlights regularly and avoid abrasive cleaners to maintain clarity.


How to Clean Your Car Windows Streak-Free

Dirty, streaky windows can make even the cleanest cars look neglected. Here’s how to get them sparkling:

  • Use a clean microfiber cloth to avoid scratches.

  • Work in small sections with a quality glass cleaner.

  • Start at the top and work your way down.

  • Wipe in a circular motion, then use a second cloth to dry.

  • Polish with a third cloth for a streak-free finish.


How to Clean Your Dashboard

Your dashboard sees it all—dust, smudges, and sometimes even spills. Here’s how to give it a refresh:

  • Vacuum First: Use a vacuum with a brush attachment to remove dust and debris.

  • Wipe Down: Use a microfiber cloth and mild soapy water to clean the surface. For heavier grime, use a soft paintbrush or toothbrush to clean crevices and vents.

  • Polish for Shine: Once dry, apply a small amount of dashboard polish for a clean, glossy finish.


How to Remove Dead Bugs from Your Car’s Exterior

Bug stains can damage your car’s paint if left untreated. Here’s how to safely remove them:

  • Wash First: Clean the affected area with soapy water.

  • Gentle Scrubbing: Use a soft sponge or cloth to scrub in a circular motion.

  • Try Mild Cleaners: For stubborn stains, use a mild abrasive cleaner or rubbing alcohol (test on an inconspicuous area first).

  • Protect Your Paint: Wash and wax your car regularly to prevent bug stains from becoming permanent.
