No Yolk! Rotten Egg Smell (Sulfur Smell Causes)

The pungent smell of rotten eggs can send people running for the hills.  So when that odor is inside your vehicle, yikes!  Yolks!  The good news is that a trained service technician can search the source of that smell and stanch the stench… that comes from another words that begins with S.  Sulfur.

Fuel contains small amounts of hydrogen sulfide, but they’re enough to stink up a vehicle when it’s not properly burned.  You may know that the smell of rotten eggs can often be a sign of a catalytic converter that isn’t working the way it should.  That could be due to age, damage or an abundance of oil that’s clogging it up. 

If a sensor in charge of managing the fuel has failed, the engine can run with too rich of a fuel mixture.  That can overload the catalytic converter and allow some of the byproducts to escape without interruption from the chemical reaction that is supposed to prevent them from going out the tailpipe.

There’s another possibility, but it’s usually only in stick shift vehicles.  That’s leaking, old transmission fluid.

Catalytic converter repairs are best left to a professional. Technicians at your vehicle service facility have equipment and training that can help them pinpoint the cause of this funky fragrance.  Once the cause is found, repairs made and/or parts replaced, the smell should go away fairly rapidly.

Below 45 Degrees in St. Peter: Consider Winter Tires

Remember snow tires? They were basically just regular tires with big, knobby lugs to get them through deep snow. They were loud and rode hard, and St. Peter drivers couldn’t wait to get them off the car. Then along came television advertisements for “all-season” radials. MN drivers ran out and bought some and we thought we were done with snow tires forever.

Tires have come a long way since then. Modern winter tires sold in the St. Peter area are much better designed for the wide range of conditions that come with MN winter weather. They are made with a rubber compound that helps them stay flexible in cold weather. Regular tires become hard and stiff at St. Peter temperatures below 45°F (7° C) which reduces their traction. That’s a concern in winter, especially with snowy or wet conditions. But it also means that St. Peter drivers are better off with winter tires in cold weather even when it’s dry.

The tread design on winter tires has been improved to move snow, slush and water. The lugs and grooves throw packed snow out of the tread as the tire rotates. This means the tread is open and ready to move more snow when it rolls around again. Summer tires can pack up with snow, which makes them more dangerous than a bald tire.

The all-season tire that is popular among St. Peter drivers is a compromise between summer and winter performance. This means they give adequate performance for St. Peter drivers in either season but aren’t great in either. Summer tires give great performance in hot weather but lousy performance in winter. St. Peter drivers need to put more thought into their tire choices these days.

If you want the performance that new winter tires can give you, you should have them properly installed by your friendly and professional service advisor at Autotronics of St. Peter. It’s best to purchase four snow tires and put them on all the wheels of your vehicle. But if you only want two, you need to put them on the rear of your vehicle, even if you drive a front-wheel drive vehicle. St. Peter drivers always want to put the tires with the best traction on the rear of the vehicle.

For more auto advice about tires for any MN season, ask your friendly and knowledgeable Autotronics of St. Peter tire professional. They can help you find the right tire for your area and for your driving needs. For the best performance from your tires, whatever the season, don’t forget preventive maintenance. Keep your tires up to pressure for the best durability, safety and performance, but don’t overinflate them. Remember, good car care provides the safest road for all of us in St. Peter.

Dashboard’s a Funny Name (Instrumental Panel Warning Lights)

Every day you drive, you’re sitting behind the dashboard. But how in the world did it get that name? Back in the days of the horse-drawn carriage, horses would kick up dirt and mud on the driver and passengers, “dashing” debris against the carriage. So those who built carriages began installing a board to protect them. So, dash-board. Dashboard.

The dashboard is still there, though changed quite a bit from the early days. Now its main purpose is to house the controls and instruments for your vehicle’s systems.

Of course, you have the speedometer, tachometer and gas gauge. But there are four warning lights you need to pay attention to on your dashboard and instrument panel. Some of these may even be gauges, depending on your model of vehicle. Regardless, paying attention to them is a good idea if you want your vehicle to keep going as long as possible.

Oil pressure—The oil pressure light will come on if your engine doesn’t have enough pressure in its system. Low oil pressure means engine parts aren’t getting lubricated properly. This can cause really serious damage and do it quickly. If your oil light goes on, call your Autotronics of St. Peter service advisor immediately if you can. Even driving a short distance may ruin your engine.

Check Engine light—If a light that looks like an engine comes on, it’s not necessarily signaling a catastrophe. But it means one or more sensors in your vehicle have detected an abnormal situation. Have your vehicle checked soon. There will be a code stored in your vehicle that a technician can read and use it as an extra clue as to what’s going on.

Brake light—If this lights up, first check if your parking brake is on. If it isn’t, you could have serious brake issues. It’s a sign you should get the brakes checked soon at Autotronics of St. Peter.

Tire pressure—Tire pressure monitors are built in to newer vehicles. They let you know if any of your tires are over or underinflated. Both conditions need to be checked out. That could prevent a blowout or premature tire wear.

The dashboard isn’t what it used to be. In fact, it’s much better now… and much more informative. Take advantage of that information and keep your vehicle running the way it’s meant to.
