Shopping for tires in St. Peter can be bewildering because there are many choices. Let’s simplify. There are four main classifications of tires, each designed for different purposes.

First off, there are summer tires. Those who buy summer tires in St. Peter are looking for maximum summertime performance. The rubber is a little softer to help stick to the road on fast corners on MN roads. The tread has wide blocks at the shoulder to stiffen the tire in turns. The tread design can handle rain but really isn’t set up for snow and ice.

Next comes winter tires. St. Peter people buy winter tires because they still like performance driving when it’s cold and slippery on MN roads, so they need a tread design that’ll really bite into ice and snow. The rubber compound is formulated to stay pliable when temperatures drop below 45 degrees F/7 degrees C so they get great traction even on dry roads. On the other end of the winter tire spectrum are tires designed to handle well in severe ice and snow conditions.

The third category is all-season tires. Most new cars in St. Peter showrooms come with all-season tires. This is a tire that is designed to be used all year round. The tread design and rubber compound is a compromise that won’t give you the extreme capabilities of summer or winter tires; but if you’re driving and weather conditions aren’t at the extreme ends of the range, all-season tires might suit you just fine.

The last category is what you might have on your SUV or pickup. All-terrain or off-road tires are designed for both highway and off-road use – a tire that gets good traction in the dirt and on off-road obstacles, but still performs well on paved St. Peter roads.

Choosing the right tire is important for St. Peter car owners. Talk with your Autotronics of St. Peter tire professional about your driving requirements and receive valuable guidance on tires that will meet your needs.

Hello St. Peter, let’s talk about your often-unnoticed but extremely important PCV valve. The energy from exploding fuel is what powers your engine. But some of the vapors from the explosions escape into the lower part of the engine, called the crankcase. The crankcase is where your engine oil hangs out. These gases are about 70% unburned fuel. If the gases were allowed to stay in the crankcase, they would quickly contaminate the oil and turn it to sludge. St. Peter folks know that sludge is one of the biggest enemies of your engine, clogging it up and eventually leading to expensive failures. Also, the pressure buildup would cause seals and gaskets to blow out. Therefore, these gases need to be vented out.

Pre-1963, gasoline engines had a hose that let the  fumes vent out into the air. In 1963, the federal government required gas engines to have a special one-way valve installed to help reduce dangerous emissions. (Can you imagine how polluted our MN air would be if every car had been releasing those poisonous fumes for the last 50 years?) Diesel engines are not required to have these valves.

The positive crankcase ventilation (PCV) valve routes crankcase gases through a hose and back into the air intake system where they are re-burned in the engine. Fresh, clean air is brought into the crankcase through a breather tube. It’s really a pretty simple system, but it does the job. The re-circulating air removes moisture and combustion waste from the crankcase, preventing sludge. This extends not only the life of your oil but the engine as well. The PCV relieves pressure in the crankcase, preventing  oil leaks.

Eventually, the PCV valve can get gummed up. Then it can’t move enough air through the engine to keep it working properly for St. Peter vehicles. If the PCV valve is sticking enough, you could have oil leaks, excess oil consumption and a fouled intake system. If you experience hesitation,  surging or an oil leak, it may be a sign of PCV valve problems. Your vehicle’s owner’s manual may give a recommendation for when the PCV valve should be replaced – usually between 20,000 mi/32,000 km and 50,000 mi/80,000 km. Unfortunately, some don’t list a recommendation in the manual, so it can be easy to overlook.

Many PCV system problems can be diagnosed by our technicians at Autotronics of St. Peter . Fortunately, PCV valve replacement is both quick and inexpensive at Autotronics of St. Peter. Proper oil changes will greatly extend the life of the PCV valve. Skipping a few recommended oil changes can allow varnish and gum to build up in the valve, reducing its efficiency. So now when your St. Peter service technician tells you its time to replace your PCV valve, you will know what he’s talking about. If you have had your car for a while and this is the first you’ve ever heard of a PCV valve, ask your technician to check yours out or call Autotronics of St. Peter at 507.934.9290.

The price of gas and the uncertain economy are both causing MN residents to review their finances. More and more St. Peter drivers are opting to keep their vehicles longer and put off purchasing a newer car. It is estimated that two-thirds of the vehicles on the roads of North America today have over 75,000 miles/120,000 km on them. And the average age of vehicles is now over eleven years. That translates to some car care issues that many St. Peter men and women haven’t dealt with in the past.

Older vehicles simply have different maintenance requirements than newer ones. Learning those requirements presents a challenge for people in St. Peter because many owner’s manuals only publish maintenance schedules up to 60,000 or 90,000 miles (96,000 or 145,000 km). Vehicle owners have to keep good records and be more involved in planning preventive maintenance if they want to keep their vehicles on the road. First of all, any service in your owner’s manual that comes with a recommended mileage interval should be continued at that interval.

For example, if it is recommended that you change your oil every 5,000 miles/8,000 km, you should continue to change your oil every 5,000 miles/8,000 km. The owner of an older vehicle has to recognize that his engine is operating under higher stress than a new one. It’s just starting to show its age. So many experts suggest that the “severe service schedule” should be followed once a vehicle has racked up some serious road distance. On this schedule, the mileage interval for many services is shortened or should be performed more often. Check with your service advisor at Autotronics of St. Peter.

St. Peter drivers who own older vehicles should also be careful not to neglect or postpone oil changes. A full-service oil change is more critical for an older vehicle than for a new one. Older engines have had a lot of time to build up sludge in their oil compartment, so changing the oil at regular intervals is a must. Skipping an oil change compounds the sludge problem. With a full-service oil change, the vehicle’s fluids are also checked and topped off. Your service advisor at Autotronics of St. Peter will also let you know if these fluids need to be replaced. Older vehicles have older seals and gaskets, which often develop tiny leaks. Regularly checking fluids will compensate for these leaks and offer a heads-up about any serious ones. So, again, it is important to stay on schedule and not skip or procrastinate a fluid check.

Older seals and gaskets begin to dry out and show their age by becoming brittle. High-mileage formulation oils and fluids can help extend the lives of these gaskets and seals. These products contain additives that recondition seals and gaskets and keep them from leaking. High-mileage formulas cost more than standard products, but in the long run they can pay for themselves by preventing more costly repair bills.

If a vehicle is getting on in years or mileage, its parts are as well. High-mileage car maintenance requires necessary repairs and replacements. Timing belts, radiator hoses, parts of the suspension system, anti-lock brakes, air bags, water pumps, alternators and batteries will not last forever and will wear out in higher-mileage vehicles. They need to be inspected regularly by your friendly and knowledgeable Autotronics of St. Peter service advisor and replaced as necessary.

But don’t go running for the new car lot just yet. These repairs may sound like a lot, but in total, they’re still cheaper for St. Peter drivers than new car payments. And if you stay on top of them and budget for them, they aren’t as burdensome as it may appear.

If you plan on driving your vehicle into its high-mileage years, there are two relationships you need to develop. The first is with your St. Peter service center. Autotronics of St. Peter can offer you invaluable auto advice and help you develop a service plan that is right for you and your vehicle. Second, you need to develop a relationship with your vehicle itself. You don’t need to name it, but you should become familiar with its noises and idiosyncrasies. Pay attention to changes in its habits such as new or unusual sounds, smells, vibrations, etc. Taking note of such things and sharing them with your service advisor can help stave off a lot of big-ticket repair issues.

As we get older, keeping up with a diet and exercise plan becomes more and more critical to maintaining good health. It’s the same with our vehicles. A preventive maintenance plan and smart vehicle care will keep them on the road and keep them safe for a good many years to come.
