Don’t Be Fuelish

If you smell gasoline in your vehicle, pay attention to your nose. That’s because it has an important message for you.

Newer vehicles should never have a gasoline smell inside. One of the most dangerous conditions can come when your fuel line system has a leak or multiple leaks. Vehicles with fuel injectors are under pressure, meaning a crack or small hole in a fuel line can allow vaporized fuel to escape, sometimes around hot engine parts. Gasoline vapor and hot metal? You see the problem.

One of the most common causes of a gasoline smell inside a vehicle is a fuel tank leak. The gas tank can rot or be punctured by road debris. A Autotronics of St. Peter technician can evaluate the condition of your fuel tank and suggest either repair or replacement.

Fuel injectors can develop small leaks around their seals or O-rings. Those can deteriorate over time as the material they are made of gets old and less flexible. A technician can replace those parts.

Modern vehicles contain something called a charcoal canister. It gathers evaporating gasoline vapors from inside your fuel tank and prevents them from venting out to the atmosphere. If that canister has a leak, you’ll smell it. One hint that you have a problem is the Check Engine light may come on.

You may have a leak in your fuel tank vent hose. Or you may be smelling gasoline simply because your gas cap is loose, the cap is faulty or—yes this does happen—your gas cap is missing altogether.

Consider the dangers of gasoline fumes seriously. Inhaling them can be bad for your health or they may start a fire. Don’t fool with fuel; have gasoline odors checked out right away.

Engine Air Filter from Autotronics of St. Peter

Many St. Peter drivers have found themselves in the following situation: They go to get their oil changed and their friendly service advisor at Autotronics of St. Peter recommends a new engine air filter. They say yes, but don’t know what an air filter is or what it does.

If this has happened to you, rest assured that you did the right thing by getting a new one. But you should never be too embarrassed to ask your Autotronics of St. Peter service advisor for more information. It’s your vehicle and you have a right to understand what you’re paying for.

Let’s review: “What does an air filter do?”

Air is the focus of this discussion. What is the air like outside in St. Peter right now? Can you see any smog? Is it full of pollen? How about dust? Anyone in MN with hay fever can tell you that there’s plenty in the air that you can’t see. Well, the engine air filter’s job is to clean that air before it goes into your vehicle engine, to mix with the fuel and be burned. Without an engine air filter, the inside of your vehicle engine would be extremely dirty from all the gunk that was burned in the cylinders.

In fact, your engine needs 12,000 times as much air as fuel for it to run. That little filter does a very big job. It’s no wonder that the air filter gets dirty and needs to be replaced. Think about a vacuum cleaner. When the bag gets full of dust and dirt, the vacuum doesn’t clean as well. It can’t move enough air to create good suction. A clogged engine air filter is the same way – the vehicle engine can’t get enough air to burn the fuel efficiently. That means less power and reduced fuel economy.

That’s why your owner’s manual has recommended that you change your filter at regular intervals. Of course the St. Peter conditions you drive in will affect how quickly the filter gets dirty. If you drive in MN where it’s very dusty or where there’s lots of pollen or pollution, you may need to change the filter sooner. The filter is easy to check visually, so your friendly and knowledgeable Autotronics of St. Peter service advisor can quickly make the call. He might recommend immediate replacement or simply let you know that it is getting close and that you’ll need to replace it soon – like at your next oil change.

Because a severely dirty vehicle air filter hurts your vehicle, many St. Peter residents find that a new air filter pays for itself in better fuel economy before the next oil change. They also make premium air filters that have been proven to increase your horsepower and torque. If more power is important to you, a high performance air filter is some of the cheapest horsepower you can buy.

The better your car breathes, the better it runs – kind of like people. And don’t worry – if you have a question or don’t understand a recommendation just ask your Autotronics of St. Peter service advisor.

The Byte Stuff (Your Vehicle’s Computers)

Nobody has to tell you that computers are a part of so many things in our lives.  Smartphones, kitchen appliances, vacuum cleaners, televisions.  You name it—it has a computer in it.  And your vehicle is no exception.

The earliest cars relied on the technology of their time, and there was no such thing as a computer.  But now, it’s not unusual for a vehicle to have as many as 150 computers in it.

They perform a variety of functions. An important one is diagnosing your vehicle’s problems.  There are various sensors throughout modern vehicles that measure thousands of data points.  When something is not working correctly, they send a signal to another computer that stores that information. The data can be read by someone who has a special computer that plugs into a port in your car.  It displays certain codes that help technicians track down the culprit. 

But it’s not just the diagnostics that are computerized.  Everything from your vehicle’s fuel injection to anti-lock brakes is.  Convenience features such as power windows, rain-sensing windshield wipers, a wi-fi-hot spot, streaming video and navigation are all sophisticated computers.  Then there are the safety features; air bags, traction control, automatic emergency braking and a host of others are all dependent on computers.

It is important that those computers work correctly because they interface with many of the other computers on board.  To properly diagnose problems with those computers requires training and special equipment. Your service facility has invested considerable resources into both, and they are equipped to properly evaluate and repair and/or replace malfunctioning components. 

Some lament the days when backyard mechanics could pull out their tools and do their own repairs.  Those days are fast disappearing with the computerization of vehicles.  But look at the bright side.  Your vehicle does so much more, has so many more features and travels far more safely than those past generations drove.  And they’re bound to get better and more sophisticated down the road.
