From Gumbo to Gas Tanks: Mixing Things That Just Don’t Belong

(Lighthearted Lessons on Bad Car Care Habits)

Here in Louisiana, we know that a great gumbo is all about the right mix. You can’t just throw in anything from the pantry and call it gumbo. No sir, there’s a rhythm to it—a balance of flavors that’s been passed down for generations. Swap shrimp for marshmallows, and you’ve got yourself a disaster nobody’s lining up to try.

Your car’s no different. It runs on its own carefully balanced “recipe.” Engine oil, brake fluid, coolant, tires, belts—they all have their place and purpose. Start mixing in the wrong stuff or skipping key ingredients, and the results can get costly (and sometimes dangerous) real quick.

Today, we’re stirrin’ the pot and talking about bad car care habits—the kind of “mixes” that just don’t belong under your hood. We’ll sprinkle in some humor, but these lessons could save you from a repair bill bigger than a seafood boil.

1. Mixing Coolant Types

You wouldn’t mix seafood gumbo with chicken gumbo mid-cook—they might share some ingredients, but they’re not the same thing. Coolant works the same way.

Different vehicles require different types of antifreeze, and mixing them can cause sludge to form in your cooling system. Sludge = overheating, corrosion, and possibly a new radiator or engine.

Better recipe: Always use the type of coolant recommended by your manufacturer, and if you’re unsure, let us check it.

2. Ignoring Oil Changes

Skipping oil changes is like forgetting the roux—it’s the base that keeps everything together. Dirty, old oil loses its ability to lubricate and clean your engine, leading to sludge buildup and increased wear. In worst-case scenarios, the engine seizes, and you’re looking at a full replacement.

Better recipe: Stick to a regular oil change schedule based on your vehicle and driving habits. And yes, synthetic and conventional oils are not interchangeable without considering your engine’s needs.

3. Using the Wrong Oil or Fluids

Pouring the wrong oil or transmission fluid into your car is like putting salt instead of sugar into your bread pudding. The results can be downright ugly.

Fluids are engineered for specific systems. The wrong viscosity or formulation can cause overheating, premature wear, or total system failure.

Better recipe: Always check your owner’s manual or ask your mechanic before topping off fluids yourself.

4. Skipping Brake Fluid Service

Brake fluid doesn’t last forever—it absorbs moisture over time, which lowers its boiling point. In Louisiana’s humidity, that process can speed up. Old, moisture-heavy fluid can cause brake fade, corrosion in brake lines, and reduced stopping power.

Better recipe: Have your brake fluid tested and replaced as needed, usually every 2–3 years.

5. Driving on Bald or Damaged Tires

We’ve said it before and we’ll say it again—bald might be beautiful, but not on your tires. Worn tread can’t grip wet Louisiana roads, increasing your risk of hydroplaning. Damage like bubbles (“tire eggs”) or dry rot can cause blowouts.

Better recipe: Check your tread depth regularly (the penny test works in a pinch) and replace tires before they become a hazard.

6. Ignoring Dash Warning Lights

That little check engine light isn’t just there for decoration. It’s your car’s way of saying, “Hey, something’s wrong.” Ignoring it can turn a small, cheap fix into a major, expensive repair.

Better recipe: Have warning lights checked promptly. Even if your car seems to be running fine, the underlying problem might be getting worse.

7. Overloading Your Vehicle

Whether it’s moving day or a Mardi Gras parade float (we’ve seen some things), loading your vehicle beyond its weight limit puts strain on your suspension, brakes, and tires.

Better recipe: Know your vehicle’s load capacity and stick to it. For big hauls, rent or borrow something built for the job.

8. Using the Wrong Replacement Parts

Cheap, off-brand parts can be like using imitation crab in a crab boil—it’s just not the same. Some parts may not fit properly, wear out faster, or cause damage to related components.

Better recipe: Invest in quality parts that meet or exceed OEM specifications.

9. Jump-Starting with Cables Instead of a Jump Box

Jumper cables might seem harmless, but one wrong connection can fry sensitive electronics, damage your battery, or even cause sparks and burns. Modern cars are especially sensitive to voltage spikes.

Better recipe: Keep a portable jump box in your trunk—it’s safer, easier, and doesn’t require flagging down another driver.

10. Skipping Preventative Maintenance Checks

Waiting until something breaks to visit a mechanic is like only cooking when you’re starving—by then, you’re rushing, stressed, and more likely to make mistakes. Preventative checks catch small issues before they turn into big, expensive problems.

Better recipe: Have a trusted shop perform seasonal or mileage-based inspections. Think of it like a routine health check for your vehicle.

Why These Bad Habits Hurt More Than Your Wallet

Mixing the wrong fluids, ignoring maintenance, or taking shortcuts doesn’t just put your car at risk—it can put you at risk. Brake failure, blowouts, and overheating aren’t just inconvenient; they can be dangerous.

Plus, bad car care habits often make it harder (and more expensive) for mechanics to fix the problem later. For example, Fix-a-Flat residue means extra cleaning time. DIY Freon can mask leaks or cause damage that complicates repairs.
