Why Your Coils Burn Out: The Main Culprits in Your E-Liquid

There's nothing worse than the harsh, burnt taste of a prematurely failed coil. It ruins your flavour and costs you money. While factors like your vaping style and device settings play a role, the number one cause of coil burnout is almost always the e-liquid itself. The key to finding an e-liquid that doesn't burn coils is understanding which ingredients are the worst offenders. Before we dive in, it helps to know what's in your e-liquid and how it reacts to heat. When certain compounds don't vaporise cleanly, they leave behind a dark, sticky residue that caramelises on your coil, leading to a rapid decline in performance.

Here are the three main culprits to watch out for in your vape juice.

The Sweetener Problem: Sucralose and Other Sweeteners

Sucralose is the single biggest enemy of coil longevity. While it makes dessert and candy flavours taste incredibly sweet and satisfying, it doesn't vaporise fully. Instead, it leaves behind a crystallised, caramelised residue that quickly builds up on the heating element. This "coil gunk" acts as an insulator, forcing the coil to work harder and overheat to vaporise the liquid. This process inevitably burns the surrounding cotton wick, resulting in that dreaded burnt taste. If a flavour is intensely sweet, it's likely high in sweeteners.

VG/PG Ratio: Is Your Juice Too Thick?

The thickness, or viscosity, of your e-liquid matters. High VG (Vegetable Glycerin) juices are significantly thicker than their 50/50 or high PG counterparts. While perfect for large, sub-ohm cloud-chasing kits, this thick consistency can cause major issues in smaller devices like pod kits and MTL tanks. The cotton in these compact coils struggles to absorb the thick liquid quickly enough, leading to poor wicking. When you fire the device without enough saturated cotton, you get a "dry hit"-the coil just burns the cotton directly. Always match your VG/PG ratio to your vape kit for optimal performance.

Dark Colours and Complex Flavours

As a general rule, the clearer the e-liquid, the kinder it will be to your coils. Dark-coloured liquids, such as those for rich coffees, heavy tobaccos, or decadent caramels, often contain flavouring compounds that are naturally more prone to caramelising and leaving residue. Similarly, highly complex flavour profiles with dozens of ingredients can contribute more build-up than a simple, straightforward flavour like menthol or a single fruit. Choosing a clearer, less complex e-liquid that doesn't burn coils is a simple and effective way to extend their life.

How to Choose Coil-Friendly E-Liquids: A Vaper's Checklist

Finding an e-liquid that doesn't burn coils is easier when you know what to look for. The information on the bottle and product description provides all the clues you need to protect your vape coils and enjoy a cleaner flavour for longer. Follow this simple checklist to make an informed choice every time you shop.

Look for 'Low Sweetener' or Unsweetened Options

Excessive sweetener, particularly sucralose, is the number one cause of coil gunk. As the sweetener heats up, it doesn't vaporise cleanly and leaves behind a dark, sticky residue that ruins your coil's cotton. For a deeper understanding, scientific studies show in detail how sweeteners affect your coils and degrade under heat. To avoid this, seek out brands known for less sweet formulations. Opt for simpler fruit or menthol profiles over complex, layered dessert flavours, as these often contain fewer additives. Remember, a 'premium' price tag doesn't always guarantee a coil-friendly juice.

Match the VG/PG Ratio to Your Vape Kit

Using the wrong e-liquid viscosity for your device can lead to poor wicking and dry hits, which quickly burns your coil. The Vegetable Glycerin (VG) to Propylene Glycol (PG) ratio determines the thickness of the juice. Follow these simple rules:

• 50/50 VG/PG: Ideal for low-power devices like pod kits and starter kits. This thinner liquid wicks easily into smaller coils. Nic Salts are almost always 50/50 and are a perfect match for pod systems.
• 70/30 VG/PG (High VG): Best for high-power, sub-ohm devices. This thicker liquid prevents leaking in larger coils and produces dense vapour clouds.

Matching the ratio correctly ensures your coil is always perfectly saturated. Browse our extensive range of 50/50 E-Liquids to find the perfect partner for your pod kit.

Opt for Clearer E-Liquids

When you're unsure, a simple visual check can save your coils. If you want the best chance at finding an e-liquid that doesn't burn coils, choose one that is clear or very light in colour. Darker e-liquids often contain ingredients that caramelise quickly, such as certain flavour concentrates, colourings, or a higher concentration of sweeteners. If coil longevity is your top priority, it's wise to avoid deep brown, dark red, or opaque liquids. This is especially true for heavy coffee, rich chocolate, and dense bakery flavours, which are notorious for their coil-killing properties.

Top 5 Flavour Profiles That Are Kinder to Coils

There's a common myth that choosing an e-liquid to prolong coil life means settling for boring, flavourless vape juice. This couldn't be further from the truth. While it's true that heavy sweeteners are the primary cause of coil gunk, you don't have to sacrifice taste for performance. Research from the NIH identifies many of the most frequently used flavourings, like vanillin, which are found in coil-killing dessert vapes. The key is knowing which flavour profiles deliver a satisfying experience without the residue.

Here are our top recommendations for finding a fantastic e-liquid that doesn't burn coils, allowing you to discover new favourites without the constant expense and hassle of changing coils.

1. Menthol and Mint

Clean, crisp, and incredibly refreshing. Menthol and mint flavourings are typically very simple compounds that vaporise cleanly, leaving behind minimal residue on your coil. These e-liquids are almost always clear in colour and contain very little, if any, added sweetener. They provide a sharp, satisfying throat hit that’s perfect for vapers looking for a powerful and clean experience. Explore our refreshing Menthol E-Liquids.

2. Simple, Tangy Fruits

Not all fruit vapes are created equal. To protect your coils, steer clear of complex 'jam', 'pastry', or 'candy' fruit blends. Instead, opt for single-note fruit flavours that rely on tartness and freshness rather than overwhelming sweetness. Think crisp green apple, zesty lemon, sharp blackcurrant, or tangy raspberry. These cleaner profiles provide a vibrant, authentic fruit taste without caramelising on your coil.

3. Classic Tobacco

For those who have recently switched from smoking or simply enjoy a rich, earthy taste, classic tobacco e-liquids are an excellent choice. Simple, non-sweetened tobacco flavours are designed to mimic the authentic taste of tobacco leaves without the added caramel, vanilla, or biscuit notes that destroy coils. If maximum coil life is your priority, avoid sweet 'RY4' or dessert-style tobacco blends.

4. Unsweetened or 'Natural' Ranges

Many premium e-liquid brands now recognise the demand for less sweetened vape juice. Some manufacturers offer specific 'natural' or 'no added sweetener' lines designed for vapers who prioritise flavour clarity and coil longevity. When browsing, look for these descriptions. These ranges are the perfect choice for anyone looking for an e-liquid that doesn't burn coils without compromising on quality. Our staff can help you find coil-friendly brands.

Beyond Juice: 4 Habits to Maximise Your Coil's Lifespan

Choosing a coil-friendly e-liquid is a great start, but it's only half the battle. Your vaping habits play a massive role in how long your coils last, saving you money and preventing that dreaded burnt taste. By combining the right techniques with an e-liquid that doesn't burn coils, you can enjoy a consistently satisfying vape. Master these four essential habits to get the most out of every coil.

1. Prime Your Coils Properly

This is the single most critical step for any new coil. Priming means pre-saturating the cotton wick before you fire it for the first time. Firing a dry wick, even for a moment, will scorch the cotton and ruin the coil instantly. To do it right, simply drip a few drops of e-liquid onto the exposed cotton ports. After installing the coil and filling your tank, let it sit for at least 10 minutes to fully saturate.

2. Stay Within the Recommended Wattage

Every coil has a recommended wattage range printed directly on its casing. This isn't a suggestion-it's the optimal power level for performance and longevity. Vaping above this range vaporises e-liquid faster than the wick can absorb it, leading to a nasty dry hit. Always start at the low end of the recommended range and gradually increase the power until you find your sweet spot without stressing the coil.

3. Avoid Chain Vaping

Chain vaping means taking multiple puffs in very quick succession. This common habit starves your wick of e-liquid because it doesn't have time to re-saturate between puffs. This creates dry spots on the cotton that can easily burn. For best results, leave 15-30 seconds between inhales to let the coil recover. If you need a stronger nicotine hit, consider a higher-strength e-liquid or a smoother nic salt instead of vaping more frequently.

4. Keep Your Tank Topped Up

Letting your e-liquid level run too low is a simple way to burn out a perfectly good coil. When the juice level drops below the wicking ports on the coil, the cotton can't absorb enough liquid and will start to dry out. A good rule of thumb is to refill your tank or pod once it's about one-third full. This ensures your wick is always submerged and ready to deliver a flavourful, burn-free vape.

Enjoy Pure Flavour, Not Burnt Coils

Putting an end to the frustration of burnt coils is simpler than you think. It all boils down to two key areas: the e-liquid you choose and your vaping habits. By steering clear of excessively sweet, dark-coloured juices and opting for clearer, balanced 50/50 or Nic Salt formulas, you’re already winning the battle. Combine this with essential practices like properly priming new coils and vaping within the recommended wattage, and you'll enjoy a consistently clean and flavourful experience every time.

Frequently Asked Questions

How long should a vape coil actually last?

A standard vape coil should last between one to two weeks for an average vaper. Heavy vapers might find a coil only lasts a few days, while infrequent users could get over two weeks. Factors like your e-liquid's sweetness, VG/PG ratio, and your wattage settings all impact its lifespan. Using a premium, clear e-liquid and proper priming techniques will significantly extend the life of your coil, giving you the best value for your money.

Can you clean a burnt or gunked-up coil?

While you can attempt to clean a gunked-up coil by soaking it in warm water, this is only a temporary fix. It may remove some residue but it will not restore a burnt cotton wick. Once the cotton is burnt, the unpleasant taste is permanent and the coil must be replaced. For a consistently satisfying vape experience, we recommend simply installing a fresh coil. It's the most reliable way to get back to pure, delightful flavour.

Are Nic Salts better or worse for coil life?

Nicotine salts themselves are not inherently worse for coils. However, many nic salt e-liquids are formulated with extra sweeteners to create intense flavours, and it's these sweeteners that cause coil gunk. If you choose a high-quality nic salt from a reputable brand that uses fewer sweeteners, you'll find your coil life is comparable to that with standard freebase nicotine e-liquids. Look for clearer liquids to maximise the lifespan of your pod kit coils.

Why does my new coil taste burnt immediately?

A new coil tastes burnt almost immediately due to a lack of proper priming. This happens when the cotton wick hasn't fully saturated with e-liquid before you fire the device, causing the dry cotton to scorch. To prevent this, always apply a few drops of e-liquid directly onto the cotton in a new coil and let it sit in a full tank for at least 10 minutes before use. This ensures a perfect first puff every time.

Does higher nicotine strength burn coils faster?

Nicotine strength on its own has a minimal impact on coil longevity. The primary culprits for burning coils are sweeteners, certain flavourings, and a high VG content in your e-liquid. Whether you vape a 3mg or a 20mg liquid, the coil's lifespan will be determined more by the liquid's composition than its nicotine level. Choosing a quality e-liquid that doesn't burn coils is far more important for preserving your hardware and ensuring great flavour.

Which specific e-liquid brands are known for being coil-friendly?

For vapers seeking an e-liquid that doesn't burn coils, certain brands are renowned for their clean formulas. Brands like Riot Squad, Seriously Fruity, and Vampire Vape often use fewer sweeteners, resulting in longer coil life. Simple, clear fruit and menthol flavours are generally a safer bet than dark, complex dessert profiles. We offer an extensive collection of these premium, coil-friendly options to help you find the perfect product for your device.
