Putting diesel fuel in a gasoline engine car can cause significant damage to the fuel system, engine, and injectors. Diesel fuel does not evaporate like gasoline and has a higher flashpoint, making it harder to ignite with a gasoline engine's spark plugs. The engine might misfire, fail to start, or run very roughly. Misfuelling is a common mistake, but it can be costly. In most cases, auto insurance does not cover misfuelling, and you will have to bear the repair expenses. However, certain car insurance companies and mechanical breakdown insurance policies may cover misfuelling costs, although it is rare.

What You'll Learn
Mechanical breakdown insurance may cover misfuelling
Mechanical breakdown insurance (MBI) is an optional extra layer of protection for your vehicle, which covers the cost of repairs, replacement parts, and other mechanical issues. It is available for new or leased cars that are less than 15 months old and have less than 15,000 miles on the clock. Once purchased, MBI can be renewed for up to seven years or 100,000 miles, whichever comes first.
MBI can be useful in the event of misfuelling, which is when the wrong type of fuel is put into a car, such as diesel in a gasoline engine. Misfuelling can cause significant problems, as diesel does not evaporate like gasoline and has a higher flashpoint, making it harder to ignite. This can cause the engine to misfire, fail to start, or run roughly.
While most auto insurance plans do not cover misfuelling, some mechanical breakdown insurance policies may include stipulations for it. For example, GEICO's MBI covers the cost of towing, fuel line drainage, and repairs. However, it is important to note that MBI does not cover routine maintenance, such as oil changes or tire rotations, and it also does not cover damage resulting from accidents or collisions.
It is essential to carefully read the fine print of any mechanical breakdown insurance policy before purchasing it to understand what is and is not covered. In the event of misfuelling, it is also vital to not operate the vehicle, but instead to have it towed to a mechanic to drain the fuel lines and assess any damage.

Comprehensive coverage may cover fuel contamination
Whether or not auto insurance covers diesel fuel in a gasoline engine car depends on the type of insurance policy you have. Comprehensive coverage may cover fuel contamination, but this is not guaranteed. Comprehensive coverage typically includes theft, fire, glass breakage, and vandalism. However, fuel contamination due to driver error is generally not covered.
If your vehicle's fuel system is contaminated due to an external event such as vandalism, comprehensive coverage would likely pay for repairs. For example, if someone intentionally contaminates your fuel, your comprehensive coverage would likely apply. In this case, you may also be able to hold the gas station liable for damages, and your deductible could be reimbursed. It is important to keep careful notes on when and where you bought the gas in question and to have the vehicle thoroughly inspected.
On the other hand, if you put diesel fuel into a gasoline-powered car by mistake, your insurance policy may not cover the repairs. This is because the contamination is due to your mistake and not an external event. In this case, you would need to check your policy to see if fuel contamination is specifically excluded. Some insurance companies explicitly state that there is \"no coverage for fuel-related issues.\"
It is worth noting that some insurance companies, such as State Farm and Progressive, are known to cover damage caused by contaminated fuel under their comprehensive insurance policies. Therefore, it is essential to carefully review your policy or consult with your insurance provider to determine if fuel contamination is covered under your specific comprehensive coverage.
If your comprehensive coverage does not cover fuel contamination, you may still be able to make a claim with the fuel supplier responsible for the contaminated fuel. Fuel suppliers typically provide information on their websites about how consumers can make claims if they have been damaged due to fuel contamination. You will usually need to provide documentation such as sales receipts, records of purchase, and repair bills to support your claim.

Collision coverage may cover fuel tank replacement
In most cases, auto insurance does not cover fuel contamination or misfuelling. This means that car insurance does not typically cover engine damage or the costs of draining your fuel tank due to a mistake. However, if your fuel tank is damaged as a result of a collision with another vehicle or object, collision coverage may cover the replacement.
Collision coverage is a type of auto insurance that provides financial protection in the event of a collision with another vehicle or object. It covers the cost of repairs or replacements to your vehicle, up to the policy limit. This includes damage to the fuel tank, which may require replacement if it is damaged in a collision.
It is important to note that collision coverage typically does not cover fuel contamination or misfuelling. If you put the wrong type of fuel in your car, such as diesel fuel in a gasoline engine, it is considered a mistake and is generally not covered by collision coverage or any other type of auto insurance. The driver is usually responsible for the costs associated with fuel contamination or misfuelling, including repairs or replacements to the fuel system.
However, there may be some exceptions to this. For example, if the fuel contamination is caused by an external event such as vandalism, your comprehensive coverage may pay for repairs. Additionally, some insurance companies, such as State Farm and Progressive, offer comprehensive coverage that includes damage caused by contaminated fuel. It is always best to check with your insurance provider to understand the specifics of your policy.
In summary, while collision coverage may cover the replacement of a fuel tank damaged in a collision, it typically does not cover fuel contamination or misfuelling. Auto insurance policies generally do not cover these types of incidents, and the driver is usually responsible for any associated costs. However, there may be exceptions, and it is important to carefully review your policy or consult with your insurance provider to determine your specific coverage.

Vandalism may be covered by comprehensive insurance
Regarding auto insurance coverage for diesel fuel in a gasoline engine car, it is important to note that misfuelling is generally not covered by insurance policies. In most cases, insurance does not cover repairs for a contaminated fuel system due to the driver's mistake. However, certain companies like State Farm and Progressive offer coverage for damages caused by contaminated fuel under their comprehensive insurance policies. Therefore, it is advisable to carefully review your specific policy to determine if such coverage is included.
Now, focusing on the topic of vandalism, it is often classified as malicious mischief or intentional damage to someone else's property. Comprehensive insurance typically covers vandalism, reimbursing you for damage not caused by a car accident, such as scratches, smashes, and broken glass. Additionally, comprehensive coverage may include theft, fire, and severe weather damage. It is worth noting that comprehensive insurance is optional and not required by law in any state. However, lenders frequently require it if you lease or finance your vehicle.
Comprehensive insurance coverage can provide financial protection against unexpected events, including vandalism. If your vehicle sustains vandalism damage, it is crucial to take specific steps to ensure coverage. Firstly, evaluate the harm, noting any stolen or damaged items inside the vehicle. Secondly, promptly contact the authorities and file an official report, as insurance companies often require a police report before accepting a claim. Take photographs of the damage from various angles, including your parking location and the time and date of discovery.
It is important to understand the limitations of your comprehensive coverage. Insurance companies usually cover only up to the market value of your vehicle, regardless of the repair cost. Additionally, comprehensive policies may not always cover personal items inside the vehicle, requiring a separate policy for those. Before filing a claim, consider getting a repair quote to decide if filing is worthwhile, as it may result in a rate increase. Remember, comprehensive insurance provides coverage for damage to your vehicle due to vandalism, but it is distinct from other types of insurance, such as liability or personal injury protection.

Bad gas due to driver error is not covered by insurance
Putting the wrong type of fuel in your car can cause significant damage. While some insurance companies may cover the costs of misfuelling under comprehensive cover, it is rare, and in most cases, insurance does not cover bad gas due to driver error. Mechanical breakdown insurance (MBI) may cover misfuelling, but it is usually only available for newer vehicles and not older ones.
If you have put diesel fuel in a gasoline engine, your car probably won't start. A gasoline engine cannot combust diesel, and diesel does not evaporate like gasoline, so the engine might misfire, fail to start, or run very roughly. If you realize your mistake immediately after fuelling, do not turn on the ignition. Starting the car will damage the engine. Instead, speak to a mechanic about draining the tank.
If you have put gasoline in a diesel engine, this is more dangerous and can cause huge damage. Regular gasoline will ignite much earlier in a diesel engine, which can cause serious issues for the fuel injector pump. Again, you will need to take your vehicle to a mechanic to have the tank drained.
To prevent misfuelling, it is important to be mindful of what type of fuel your vehicle requires. You can find this information in your vehicle's owner's manual and, in many cases, inside the door of your gas tank. Fuel pumps are also clearly labelled, and diesel nozzles have a different shape that prevents them from being inserted into a gasoline tank. If the nozzle doesn't fit easily, then you are likely using the wrong type of fuel.
