For most vehicles, draining the fuel tank is a pretty straightforward procedure that can be done with a minimal amount of tools or special knowledge. As always, take precaution when working with fuel, as it is highly flammable, and remember to properly dispose of or store any of the fuel that you drain.
Degradation occurs from the get-go but most gas stays fresh for a month or two without issue. However, gas that is more than two month old is generally OK to use with only minor decreases in performance. Gas that is older than a year can cause issues, like engine knocking, sputtering and clogged injectors.
Depending on the car, you can easily spend anywhere from $400 to $1,500+ on a full fuel system flush, which is what you will need in order to ensure no diesel reaches the combustion portion of your engine.
Water in the gas tank may lead to the car bucking, stalling or not starting at all, or starting the car could be difficult. This is because the water and fuel separate, especially when the car has been sitting for a while, and the water sinks to the bottom with the fuel on top.
Safety precautions. We do not recommend attempting to siphon by yourself as fumes from gasoline or diesel can cause dizziness and even fainting. The last thing you want is to black out with liters of a flammable substance flowing out of your car and onto the floor.
Because it’s also a better cleaner than ethanol or methanol, it removes many deposits in a fuel system. … For a typical 40-gallon fuel tank, one half to one pint of isopropanol will disperse the water and get your engine running satisfactorily.
If you do have water, gas floats on water, so you’ll see a bubble at the bottom of the jar. You can siphon the water from the bottom of your tank, or take it to a professional. If phase separation is occurring from mixing water and ethanol, the bubble at the bottom will be gelatinous.
Re: Does Fuel Stabilizer Go Bad? Sta-bil definitely helps, but keep in mind that it probably loses its ability after a year or so.
Mixing 2% diesel fuel into gasoline will lower the overall octane rating by 1 point. Getting 10% diesel contamination lowers octane by 5 points, which is enough to create problems in most engines.

It’s normal for your car’s gasoline engine to run for around 200,000 miles before it needs a serious overhaul, or you need a new vehicle. But diesel engines can continuously run for an impressive 1,000,000-1,500,000 miles before needing any major work.
Never store gasoline in your home. Storing gas in your home is not just a serious fire hazard, but a public health hazard as well. Exposure to the fumes is associated with certain health risks. Gasoline should always be kept in an outdoor structure such as a tool shed, storage barn, or separate garage.
Does petrol and diesel expire? The RAC say petrol has a shelf life of around six months, but that is only if it is stored correctly. … At higher temperatures, petrol will degrade more quickly, for example, at 30 degrees petrol will last around three months.
Even a small amount of water in the gas tank is bad. Water will corrode and can seriously damage the fuel pump, fuel lines and fuel injectors.
When the engine is fine, drive your vehicle slowly. Diesel engines are made from different materials. This is also true in the fuel system. Putting even a small amount of petrol in diesel engines can lead to damages to the entire fuel system.
Siphoning gas from another vehicle is free, but it’s illegal. If you get caught, you will have to pay a fine and/or court costs, in which case it will not be cheaper and it will certainly be more inconvenient.
