What To Do When You Put The Wrong Fuel Into Your Vehicle

Once every 3 minutes, a driver in the UK will put the wrong kind of fuel into their vehicle. This has happened to all of us and is an extremely common mistake to make. That is why today we’ve decided to show you what happens when you do, as well as how you can remedy it.

At the start of every car owner’s ownership is a period where they do not know what kind of gas the car runs on. Most of us usually ignored it at first and just figured that we would get it right. Well, today we are here to tell you that that precise action could have had some critical consequences for your car.

While adding the wrong kind of fuel may seem to be harmless, it couldn’t be further from the truth.

Using the wrong octane

Here is the only situation where the logic of ‘fuel is fuel’ actually does apply. When you are mixing octanes, or using the wrong octane, all that might do is make your car run a bit slower, or make you spend more money on fuel. This is mostly because when mistaking octane, you aren’t fundamentally changing all that much about the fuel, because there isn’t all that big of a difference between the compositions of high and low octane fuels.

The absolute worst that can happen is if you do this consistently you may have some minor issues with corrosion, but it’s highly unlikely to happen. In addition to this, this only happens if you repeatedly do it.

Putting Gasoline in Diesel

If you mix a majority of gas with diesel you’ll start facing some more serious issues, depending on how much of it was mixed together. This can be extremely dangerous, as it lowers the flash point of the diesel, as well as forming pockets which means that the flashpoint won’t be consistent throughout the mixture. Given how different these two flashpoints are, even 1% of gasoline is enough to cause permanent engine damage to your car.

This uneven combustion can also cause damage to the fuel pump and diesel injectors, due to the drop in lubrication.

Putting Diesel in Gasoline

Now, you may think that since the flashpoint gets lowered, in this case, there’d be not as much danger to the car right? Well, this isn’t exactly the case, in fact putting diesel in the main gasoline mixture is also a sure recipe for disaster.
Due to the increased explosiveness of this mixture, the piston and rod are at a large risk of large damage. This is mostly due to the outright massive difference in octane and flash point. However, this requires a 2-10% diesel contamination to happen.

This can also result in hydro-locking the cylinders, this alone can blow your head gasket, it could also lead to ignition in the catalyst converter, which can lead to thousands of dollars in damages.

Putting Gasoline in a Diesel Car

This is probably the most critical problem. Do not start your car under any circumstances. This will wreak havoc among the insides of your car, most likely causing entirely irreparable damage to your engine and fuel lines. Some components may even blow up upon ignition. Be sure to call fuel removal services as soon as possible, because they’re the only solution to this.

Putting Diesel in a Gasoline Car

This damage usually isn’t as severe, and it’s much easier to do than the converse. There will be smoke coming out of your car, as well as some damage to the spark plugs, in addition to this, the car will most likely refuse to start. This is because relatively speaking, Diesel is a less ‘powerful’ fuel.

What Can I Do About It

In case you’ve done one of these things, there is little you can do other than call a fuel removal service. These may seem a bit pricey, but they’re much cheaper than the repair job you’ll need if you don’t call them.
