Putting the wrong fuel in your car is a costly mistake that can set you back thousands of dollars. In most cases, insurance does not cover a contaminated fuel tank, and you will have to foot the bill yourself. However, some insurance companies do cover fuel contamination, and it is worth checking with your provider to see if your policy includes a 'dummy clause'. If you have comprehensive coverage, your insurance company may pay for the repairs minus your deductible. It is also important to keep good records of your maintenance habits and to review your owner's manual to prevent misfuelling.

Dummy clauses
Putting Diesel Exhaust Fluid (DEF) into a diesel fuel tank can cause significant damage to the engine and fuel system. The entire fuel system, including the tank, lines, and injectors, may need to be drained, cleaned, or replaced, resulting in costly repairs. The repair bill can be more than you may be able to afford, with estimates ranging from $7700 to $20,000 to replace the entire fuel system.
In most cases, insurance does not cover a contaminated fuel claim. However, some owners have been successful in getting their insurance companies to cover this mistake. It is essential to review your policy details and understand any exclusions. Some policies explicitly exclude coverage for misfuelling incidents, while others may offer protection through what are called "dummy clauses".
To increase the chances of your claim being approved, it is recommended to keep good records of your maintenance habits and take preventive measures to avoid such incidents. When you go in to fill up, be careful and eliminate distractions. Clear labeling of DEF and diesel fuel containers, as well as driver education, can also help prevent accidental mix-ups. Additionally, be sure to contact your insurance company promptly if this mistake occurs and seek professional repairs.
While insurance coverage through a dummy clause may be possible, it is not a sure thing. It is always a good idea to review your policy carefully and understand the specific coverage and exclusions to know what you are and are not protected against.

Repair costs
The repair costs for DEF in the fuel tank can be high, ranging from $3,300 to more than $20,000. The cost depends on the extent of the damage, the make and model of the vehicle, and whether the insurance company covers the repairs. Some insurance companies may cover the cost of repairs if the vehicle owner has a "dummy clause" in their policy, which provides protection for accidental misfuelling. However, insurance coverage for this type of incident is not guaranteed, and some companies, such as USAA and Nationwide, have been known to deny claims for fuel contamination.
If DEF is put into a diesel fuel tank, it is essential to act quickly to prevent further damage. The contaminated fuel should be drained and the tank flushed. The fuel filters and other components may also need to be replaced. The cost of these repairs can add up, especially if the entire fuel system needs to be replaced due to corrosion caused by DEF.
To prevent misfuelling, it is important to be attentive and eliminate distractions while refueling. Knowing your vehicle's fuel type and investing in a misfuelling prevention device can also help avoid costly repairs.
In some cases, gas stations may be held liable for selling bad or contaminated gas that damages a vehicle. If the vehicle exhibits unusual behaviour such as sputtering, stalling, or difficulty starting, it is important to stop driving and inform the gas station manager. However, it can be challenging to prove that the bad gas directly caused the damage, and insurance typically does not cover contaminated fuel.
Overall, the repair costs for DEF in the fuel tank can be significant, and it is important to act quickly and carefully to minimize the potential financial burden and damage to the vehicle.

Fuel contamination
One specific example of fuel contamination is the accidental addition of Diesel Exhaust Fluid (DEF) to a diesel fuel tank. This mistake can have costly consequences, with repair bills ranging from $7,700 to $20,000, as the entire fuel system may need to be replaced due to corrosion. While insurance typically does not cover fuel contamination or misfuelling, some owners have successfully claimed it as vandalism or through a dummy clause in their policy. However, insurance companies may require proof of regular maintenance and records showing that such mistakes are not frequent.
To prevent fuel contamination, it is essential to ensure proper fuel handling and storage practices. This includes using well-maintained fuel tanks, securing caps and lids tightly, and preventing water ingress. Additionally, regular fuel testing can help detect contamination early on, allowing for prompt remediation before extensive damage occurs.
In the event of suspected fuel contamination, it is crucial to refrain from starting the vehicle to avoid further damage. Instead, seek the assistance of a mechanic to drain the tank and perform any necessary repairs. While insurance coverage for fuel contamination is generally limited, it is worth reviewing your policy and consulting with your insurance provider to explore potential options for coverage.
Overall, fuel contamination is a significant issue that can result in costly repairs and equipment damage. By understanding the causes, prevention methods, and available remedies, individuals and businesses can mitigate the impact of fuel contamination and minimize its financial burden.

Misfuelling
If your policy does not cover misfuelling, you may be able to purchase misfuelling cover separately, either as an add-on to your existing policy or by switching to a new provider. Alternatively, most breakdown policies will cover the cost of draining your tank and taking your car to a garage, and some may also cover repair costs. Mobile engineers and mechanics can now come to your rescue at the roadside, so you won't necessarily need to have your car towed.
If you accidentally put AdBlue/DEF (diesel exhaust fluid) in your fuel tank, do not start your car as this can cause a lot of damage. Some insurance policies may cover the cost of repairs in this situation, but it depends on the specific terms of your policy. In any case, you should contact your insurance provider as soon as possible and be prepared to provide any relevant breakdown or repair receipts.

Insurance coverage
In most cases, insurance does not cover a contaminated fuel tank. However, there are some instances where insurance companies have covered the costs of repairs due to DEF fluid contamination. For example, Progressive Insurance covered the costs of repairs for one of their customers, minus the deductible. Similarly, another insurance company covered the costs of repairs for a customer minus their deductible of $245.
Some insurance companies may cover fuel contamination under comprehensive coverage. For instance, Nationwide covered the costs of repairs for a customer under comprehensive coverage. On the other hand, some insurance companies like USAA and State Farm have denied claims for fuel contamination.
It is important to note that insurance coverage for fuel contamination is not guaranteed, even with a 'dummy' clause. A 'dummy' clause may provide protection and increase the likelihood of insurance coverage, but it is not a sure thing. To increase the chances of a successful claim, it is recommended to keep good records of maintenance habits and service records. Additionally, it is crucial to act promptly and contact the insurance company before any repair work has been started.
To avoid the costly mistake of DEF fluid contamination, it is advised to be attentive while refueling your vehicle and eliminate distractions. Knowing your vehicle and using a misfuelling prevention device can also help prevent this issue.
