What is the best additive for old gas?

When it comes to dealing with old gas, often the first instinct might be to remove it and dispose of it properly, then replace it. However, there are times when this isn’t feasible, like when you’ve filled a tank and the fuel has degraded. In such cases, some are adamant about trying to restore the gasoline with the hope that a stabilizer will stop further degradation. One approach is to add a gallon of gas from the gas station, then pour it into your car’s gas tank and fill up with fresh gas. This might not hurt, especially if you’re trying to figure out how to dispose of the new gasoline that has a little old fuel mixed in. In scenarios where there’s a lot of new fuel to burn off, it’s generally ok and shouldn’t cause engine problems. The real solution here is finding a way to get rid of old gas safely if you don’t use it.

What can I put in old gas to make it better? 

Sometimes, it’s the other way around you might want to set aside old gas and treat it with new gas in a small dose to get rid of it. In other words (IOW), you could put a liter of old gas into ten liters of new gas. This gradual process helps in diluting the old gas, slowly improving its quality. It’s a practical approach for those who have a small amount of old fuel and want to utilize it without wasting it. This method is especially useful for equipment that doesn’t require high-performance fuel, allowing for an efficient and environmentally friendly way of managing old gasoline.

Can a fuel additive be used for old gas? 

When it comes to old gas, no additives can undo the degradation that occurs when gasoline is stored too long or in improper conditions. However, additives can make fuel stay fresh longer if they are mixed in before storing the fuel. This preemptive approach is key to maintaining the quality of gasoline, ensuring that it remains effective for future use. By integrating a quality additive prior to storage, you essentially safeguard the fuel against common degradation processes, thereby extending its shelf life and keeping it ready for when you need it.

Is there an additive for bad gas? 

The question of whether no additives can improve octane or dry out water in old gas that’s gone bad is quite straightforward. Unfortunately, nothing can do much to rejuvenate gasoline that has significantly deteriorated. Once fuel reaches a certain point of degradation, its chemical composition alters to a state where conventional additives can no longer restore its original quality or performance. This is an important consideration for anyone dealing with aged or poorly stored gasoline, emphasizing the need for timely usage and appropriate storage conditions to maintain fuel quality.

Using a Fuel Additive for Old Gas

Fuel has a limited storage life, and its quality can degrade and break down due to chemical reactions when exposed to air, water, and catalytic metals. In real time, this can lead to end results where gas becomes darkened or stratified, or has undergone phase separation, a common issue with alcohol or ethanol fuels. Diesel fuel also faces similar problems. This is not just a consumer problem businesses that store gasoline or diesel fuel for sizeable periods also encounter these challenges. Even consumers who buy small to medium volumes of gas for containers intended for present-day or near-future use can forget, only to find the fuel later, significantly aged and degraded.

What To Do With Old Gas

The question of whether you can restore old gas to a usable condition largely depends on how far gone it is. When you look for signs in ethanol gasoline, which is most gasoline nowadays, if it has phase-separated, it’s often too late to treat it effectively. For gasoline in storage that’s older than a few months and is undergoing phase separation, the process may have fully concluded, leaving two layers in the tank a layer of water and alcohol at the bottom and the rest of the gasoline on top. In such cases, restoration becomes impractical, and the focus shifts to safe disposal methods.

Bogus Fuel Additives To Fix Phase-Separated Gas

When gas has phase-separated, it’s unlikely that any additive will do anything worthwhile. Beware of bogus fuel additives that claim to restore phase-separated gasoline. They might help if the separation has barely started, but for most people, once they think about it and decide to try these products to magically repair fully-separated gasoline, they’ll likely find that nothing is cost-effective in returning the fuel to its previous homogenous condition. In these cases, the best course of action is usually to safely dispose of the compromised fuel and replace it with fresh gasoline.

Darkened Old Gasoline: What Can You Do?

When gasoline is not phase-separated but has darkened, it indicates that it has reacted internally, with heavier-end components polymerized, forming gums and varnishes. These substances can still burn in an engine, but the heavier components won’t fully combust, potentially leaving deposits in combustion areas, injectors, or carburetors. Such deposits do a number on the efficiency of your engine. It wouldn’t be recommended to burn this fuel unless you add a fuel additive that contains a high level of detergency. Its function is to remove the deposits formed, giving your engine the best chance of staying problem-free. This is a crucial step in managing old gasoline to maintain engine health and performance.

Stick To PIB or PEA Detergents

When dealing with old gas, your best position is to use a high detergent fuel additive, particularly from reputable types. These additives specifically tell on their labels if they contain injector detergents. Be wary of generalized claims about cleaning. A secondary benefit of these additives is that they don’t rely on weird sounding, new technology from no-name brands that claims uses of nanotechnology to clean your engine. Instead, look for excellent and effective detergent packages like PIB (polyisobutylene) detergents or PEA (polyether amine), which are formulated to be compatible with gasoline that contains more than 20% ethanol. These higher level detergent chemistries give you the best chance of successfully treating old gas, provided it hasn’t undergone phase separation, of course.
