You’re standing in the middle of a big-box hardware store, surrounded by shimmering stainless steel and black powder-coated lids. It’s overwhelming. On one end, you’ve got those dinky two-burner units that look like they’d struggle to host a solo hot dog. On the other, there are six-burner behemoths that look like they require a commercial pilot’s license to operate. Most people gravitate toward the middle, and honestly, they're right to do so. Four burner gas grills represent the absolute "Goldilocks zone" of outdoor cooking. They offer enough space to feed a crowd without burning through a $20 propane tank every three days.
But here’s the thing: not all four-burner setups are created equal.
I’ve spent years hovering over hot grates, and I’ve seen people drop two grand on a "professional" rig only to realize the heat distribution is so patchy they can only use the middle six inches. You’ve probably been there too. One burger is charred to a crisp while the one next to it is still looking suspiciously pink. It’s frustrating.
When we talk about the utility of four burner gas grills, we aren't just talking about raw surface area. We're talking about zone control. This is where the magic happens. With four independent burners, you can finally master the art of indirect heat—searing a ribeye over the far-left burner while your delicate asparagus spears hang out on the right side, completely unbothered by direct flames.
The BTU Myth and Why Your Grill Might Still Be Cold
If you look at the spec sheet for most four burner gas grills, you’ll see a big, flashy number for BTUs (British Thermal Units). Salespeople love this number. They’ll tell you that 48,000 BTUs is "industrial strength."
Don't fall for it.
BTUs are essentially a measure of fuel consumption, not efficiency. Think of it like a car’s engine; just because it sucks back a lot of gas doesn't mean it’s actually fast. If a grill is poorly insulated or has a lid made of thin, cheap sheet metal, all those BTUs are just flying out into the atmosphere. You’re heating the neighborhood, not your steak. What you actually want to look at is "heat density"—the BTUs divided by the primary cooking surface area. Ideally, you’re looking for something in the neighborhood of 80 to 100 BTUs per square inch.
I remember testing an old Genesis model against a generic "budget" four-burner that boasted higher total BTUs. The Genesis won every single time. Why? Because the cookbox was heavy-duty cast aluminum. It held onto the heat. The budget model had huge gaps in the back where the wind just whistled through, stripping away the temperature the second the lid opened.
Why Four Burners Beat Three (Every Single Time)
Some folks argue that a three-burner is "plenty." They're wrong.
Basically, it comes down to geometry. On a three-burner grill, your "indirect" zone is limited. If you turn off the middle burner, you have two hot zones on the outside. That’s okay, but it’s cramped. With four burner gas grills, you have way more flexibility. You can turn off the two right-hand burners and have a massive, cool "roasting" area. This is how you cook a whole chicken without burning the skin to a bitter carbon shell. Or, you can just light the two middle burners for a concentrated sear.
It’s about versatility.
Materials Matter: Stainless Steel vs. Porcelain-Enamel
This is where the "buy once, cry once" philosophy really kicks in. You’ll see two main types of grates and lids on the market.
- Stainless Steel: It looks great in the showroom. If it’s high-quality (look for 304 grade), it’ll last forever. But if it’s the cheap 430-grade stuff? It’ll start pitting and rusting within two seasons if you live anywhere near salt air or humidity.
- Porcelain-Coated Cast Iron: My personal favorite for actual cooking. These grates are heavy. They have "thermal mass," meaning they don't lose their temperature the moment you drop a cold piece of meat on them. You get those beautiful, thick sear marks that look like they belong in a steakhouse.
The downside to cast iron is maintenance. You can’t just leave them out in the rain and expect them to stay pristine. You’ve gotta treat them like a cast-iron skillet—keep them seasoned, keep them clean. Honestly, it’s worth the five minutes of extra work.
The Secret to Not Catching Your Deck on Fire
We need to talk about grease management. It’s not sexy, but it’s the difference between a great BBQ and a call to the fire department. Most cheap four burner gas grills have a shallow, flimsy grease tray that’s a nightmare to slide out.
Look for a "funnel" system.
Brands like Weber and Napoleon have spent decades perfecting the way grease flows away from the burners. You want a system where the drippings hit a "flavorizer bar" or a sear plate, vaporize (which adds that smoky flavor), and then any excess is funneled into a centered, replaceable drip pan. If you see a grill where the grease just sits in a flat pan under the burners, walk away. That’s a flare-up waiting to happen.
I once saw a guy try to cook 20 high-fat burgers on a poorly designed four-burner. Within ten minutes, the entire underside was a literal inferno. He lost his eyebrows, and the burgers ended up tasting like a tire fire.
Real-World Footprint
Think about your patio. A four-burner grill is usually about 50 to 60 inches wide once you factor in the side shelves. Do you actually need those shelves? Some models have "drop-down" shelves, which are a godsend if you’re working with a smaller balcony or a crowded deck.
Always measure your space twice.
And check the wheels. Cheap plastic casters are the bane of my existence. If you plan on moving your grill from the garage to the patio, look for heavy-duty, locking rubber wheels. Trying to drag a 150-pound grill on tiny plastic pegs over deck boards is a recipe for a bad Saturday.

Common Misconceptions About Gas Grilling
- "Gas has no flavor." False. Most of that "grill flavor" comes from meat juices dripping onto hot metal and vaporizing back into the meat. It doesn't actually come from the charcoal itself unless you're using wood chunks for smoke.
- "More burners = More heat." Not necessarily. It just means more control. A well-built two-burner can get hotter than a poorly-built four-burner.
- "You need a side burner." Honestly? Most people never use them. Unless you’re planning on boiling corn or sautéing onions outside while you grill, that side burner usually just becomes a dusty shelf for your beer. Save the money and put it toward better grates.
Infrastructure: Natural Gas vs. Propane
When you're buying one of these, you have to choose your fuel source upfront. You usually can’t just swap them later without a conversion kit (which can be a giant pain).
Propane (LP) is the standard. It’s portable. You can take your grill to a different part of the yard if you want. But running out of gas mid-cook is a rite of passage for every griller. It's the worst. You’re halfway through a rack of ribs, and the flame just... dies.
Natural Gas (NG) is the dream. If you have a gas line out to your patio, you never have to worry about tanks again. The pressure is a bit lower, so the grill needs specific orifices to work correctly, but the convenience is unbeatable. Just keep in mind that you're now tethered to a specific spot.
What Actually Breaks First?
It’s almost always the igniters.
You press the button, you hear the click-click-click, and nothing happens. Then you smell gas. Then you get scared. On high-end four burner gas grills, the ignition systems are shielded or use "jet-fire" tech that’s much more reliable. On budget models, the wires are exposed and they’ll corrode or melt.
Pro tip: Always keep a long-reach butane lighter in your grill cabinet. Even the best igniters fail eventually.
The second thing to go is the "tents" or flavorizer bars. Since they sit right above the flame and get pelted with salt and fat, they take a beating. When you’re shopping, look at how thick those bars are. If they feel like soda can aluminum, you’ll be replacing them in 18 months. You want heavy-gauge stainless steel or porcelain-coated steel there.
Actionable Steps for Your Next Purchase
If you're ready to pull the trigger on a new setup, don't just look at the price tag.
- The "Wiggle" Test: Go to the store and grab the handle of the lid. Shake it. Does the whole grill wobble? If the frame is flimsy, the heat retention will be garbage. A good four-burner should feel like a tank.
- Check the Warranty: This is the ultimate "tell" for quality. A company that offers a 10-year or "lifetime" warranty on the cookbox and burners (like Napoleon or Weber) knows their product won't rust out. A 1-year warranty is a massive red flag.
- Ignore the Extras: Don't get distracted by LED lights on the knobs or built-in bottle openers. They're cheap gimmicks. Focus on the thickness of the metal and the quality of the burners.
- Invest in a Cover: I don't care if the salesman says it's "weatherproof." It's not. Water gets into the valves, spiders crawl into the burner tubes (true story, they love the smell of gas), and the sun will fade the finish. A $50 cover adds five years to the life of your grill.
- Clean Your Burners: Once a year, take the grates out and use a toothpick or a small paperclip to clear out the little holes in the burner tubes. Spiders and carbon buildup can block them, leading to uneven heating and yellow, "dirty" flames.
Cooking on a four-burner shouldn't be a chore. It should be the reason you want to stay outside until the sun goes down. When you get the right one, it becomes an extension of your kitchen—just with better scenery and a lot more char. Keep it clean, watch your temps, and stop obsessively flipping the meat. Let the grill do the work.
