How Do You Know if Gas Is Bad
We take gasoline for granted.
For well-nigh of u.s., information technology's as simple as putting gas in, then driving away. These days, it's very rare that you'll become bad gas from a gas station. In over 18 years as an automobile mechanic, I've never seen someone's engine damaged by bad gas.
It just doesn't happen as much every bit it used to.
Simply it does still happen.
Back in 2012, over 4.vii one thousand thousand gallons of gas were recalled from BP stations in Chicago, Northwest Indiana, and Milwaukee. The bad gas, in this instance, was contaminated with polymer residuum, which doesn't burn in automotive engines and tin cause damage to the engine.
By and large speaking, bad gas is commonly the result of contagion from your fuel tank or fuel line. It tin be the event of your machine sitting for an extended period of time, or from water making its way into the fuel tank.
Past the time you're finished reading this guide, you'll exist an expert in diagnosing if your car actually has bad gas, every bit well as correcting the problem if it becomes an issue.
Y'all'll learn everything you need to know – and probably some things you lot don't need to know.
What Causes Gas To Get Bad?
Gasoline doesn't stay skilful forever. The countdown starts as soon as y'all betrayal gasoline to air. After around 30 days or so of sitting in your fuel system, your gasoline starts to oxidize.
When gasoline oxidizes it tin can gunk up your fuel system by turning into varnish which can glaze your fuel system and engine. Every bit gasoline degrades, it goes from clear in color to looking more than similar apple cider. This "apple tree cider" gasoline then begins to gum upwards your fuel system and your engine.
Even worse, today's gasoline often contains ethanol. When these deposits form, the ethanol in them attracts h2o from the atmosphere (it's hydrophilic for all you chemistry nerds).
Generally speaking, old gas in your car isn't the end of the globe if you've let it sit for only a couple of months, but if your automobile has been sitting for vi months or more, y'all can meet some problems and you may demand to employ something like Seafoam.
Nosotros'll get into what exactly you lot need to do in a bit.
Age is the most mutual cause of bad gas, but it's far from the simply 1.
Water can also get into your gas tank. This tin can be caused by a loose gas cap, or from condensation. It's also possible that water can make information technology in from the pump itself – although this is getting more and more uncommon.
Besides historic period and water, you may besides take contaminated gas from a cracked fuel line, or from flakes coming from your gas tank.
What Are The Symptoms Of Bad Gas In Your Car?
Bad gas is fuel that doesn't combust as expected. With that in mind, well-nigh of the symptoms are related to the car not running as expected.
Your car relies upon fuel existence delivered to the combustion sleeping accommodation and igniting optimally. When this doesn't happen, the machine often hesitates and suffers from a lack of performance. With that in mind, some symptoms of bad gas to look out for include:
one: Difficulty Starting Your Car
If your car cranks but won't start, it could mean that you have bad gas. Contaminated gas doesn't provide plenty ability to start the engine. Still – if your engine doesn't start, you shouldn't automatically assume you have bad gas. Anything from bad spark plugs to a busted fuel pump tin cause your engine not to get-go.
If yous have a lot of bad gas in your tank, this tin can cause your automobile not to outset in some cases.
2: Sputtering Or Pinging Sounds When The Auto Is Idling/Driving

4: The "Bank check Engine" Lite Coming On While Driving
Bad fuel tin cause your car to run lean. If you take an OBD-Ii code reader, the lawmaking will almost always chronicle to your engine running lean.
v: Burning More Gas Than Usual
When y'all have bad gas, your engine will take to work harder than normal to produce the same amount of power. This can show upward every bit your machine called-for more than fuel than usual. On its own, this isn't a smoking gun, but if you notice it together with the other symptoms, pay attention.
6: Trouble Accelerating
If you have bad gas, it'southward common for you to accept trouble accelerating or going up hills or other steep inclines because bad gas doesn't burn down correctly.
7: Speed Changes While Driving Without Pressing The Gas Pedal
Bad gas can also cause your car to abruptly alter speeds while driving. Yous may notice a sudden slow down, followed past a surge of speed.
What Are The Symptoms of H2o In Your Gas Tank?
The symptoms of water in your gas tank depend on how much water gets into your gas tank. If there'south only a trivial flake of water, you lot might non notice information technology at all.
But if at that place'southward a lot of water in the tank – y'all'll definitely know.
The main thing to sentry out for is hesitation when you try to accelerate. When in that location's water in your gas, your engine won't be able to perform up to standard. The more water in your gas, the worse this volition become.
The other symptoms I've already covered above.
So, Tin can Bad Gas Damage Your Car?
The answer is yep – just for it to get to that point y'all demand to actually allow things go for a long fourth dimension. Bad gas tin course deposits that tin cause problems in your engine. Again, this is very rare and probably won't happen, but it'due south good to know.
Still, if you get bad gas from a gas station, you lot could be in for quite the repair pecker. Although I've never seen the damage personally, I accept seen reports ranging from $1,000 to $2,500+.
How To Get Reimbursed For Bad Gas
As I previously mentioned, most bad gas is probably not the kind y'all'll exist able to be reimbursed for. For instance, if your gas goes bad because information technology's onetime you're not going to go reimbursement.
However, if y'all put gas in your car and information technology most immediately starts coughing and sputtering, and so you lot may be on to something.
To foreclose yourself from getting the shaft, you need to make sure y'all go a receipt. If you can evidence you lot got bad gas from a gas station, then yous'll exist able to go reimbursement.
More likely than not, y'all'll exist paid through the gas station's insurance policy. Y'all may also desire to call your state's consumer protection bureau to study that you got bad gas to foreclose others from getting burned as you did.
With that being said – how can you exist certain if you have bad gasoline or non? You test for information technology.
How to Examination For Bad Gasoline
The start thing you should do is enquire yourself if it's possible that your gasoline was contaminated due to your own fault. Whether that was through letting your car sit down, or through a loose gas cap, or something similar.
If you can rule these out, then information technology'south somewhat difficult to test the gasoline without special tools.
A fuel test process and kit (without sending out to a lab) involves 3 steps.
- The kickoff involves lowering a probe to the bottom of the tank with a paste that changes color if it touches moisture. The probe almost resembles a wheel cable in a clear sheathe. This requires the probe and the color-changing paste.
- The second involves retrieving a sample of the gasoline. Identify the gasoline in a graduated cylinder. Add some corporeality of windshield washer fluid. Cork the sample and milkshake the tube. Wait until information technology settles. Compare how much gasoline you put into how much is left after everything settles. This shows how much alcohol is in the fuel. It should be no more than 10%. All this test needs is a graduated cylinder that can survive gasoline. This is the easiest thing to acquire.
- The 3rd involves retrieving a sample of the gasoline. This test measures the volatility of the gas known as Ried Vapor Pressure and requires another special testing tool. Chill the gasoline and tool on ice for 30 min. Cascade the fuel into the tool and close it. Identify the tool into hot water for 10 min and measure the water temperature. Read the force per unit area from the guess on the tool. Compare the pressure and temperature to a table that comes with the tool.
How To Become Water Out Of Gas
If y'all accept h2o in your gas, the offset step is to figure out how much water you have in your tank. If your car is still drivable, chances are you don't have too much water in your gas tank.
Notwithstanding, if you're having serious performance issues – then you'll need to go some other road.
In this case, you lot take a few options.
They include using a production like Heet or by doing it yourself with dry isopropanol alcohol.
Considering Heet is about $three on Amazon, it'south unremarkably the easiest pick.
If Heet or isopropanol booze doesn't fix the problem – then you'll need to siphon the gas out of your tank.
Get a fuel siphon, and and then feed the tube into your gas tank and become pumping. Pump the siphoned fuel into a clear container so you tin can inspect it, and then refill your gas tank with adept dry fuel.
How To Gear up Bad Gas
Fixing bad gas, on the other hand, is much simpler. If you have true bad gas – not sometime gas, or waterlogged gas, then you'll demand to siphon the gas out of your tank and pump new gas in.
Don't mess around with this, because bad gas can crusade damage when it does happen, fifty-fifty if it but happens rarely.
