The price of gas in MN has got people in St. Peter talking. It seems that St. Peter folks who need a bigger vehicle to carry family and gear, or provide four wheel drive, are hit especially hard. That is why we thought it would be good to review some things that anyone can do to improve fuel economy.

First let’s start with how we drive around MN. People in St. Peter may not realize that they can really save on gas by just changing a few driving habits. One of the biggest is jackrabbit starts – you know, flooring the gas as soon as the light turns green. That really wastes a lot of fuel. Building up your speed at a slower pace uses less fuel and is easier on your engine and drive train. And don’t drive with one foot on the brake. That’s also a drag on fuel economy, and it wears out your brakes faster, too.

Another thing St. Peter drivers can do is drive more slowly – but only when it’s safe. Sometimes on the freeway we drive an extra five … ten . . . twenty … over the speed limit. We do it to save time, but it only saves a few minutes out of maybe an hour long drive, and we may use 10 to 15 % more gas. Just leave a little bit earlier, save some money and arrive more relaxed.

St. Peter drivers can also try and combine all of their errands for the day into just one trip, rather than several. If you can put off a trip today that can be combined with one tomorrow, you can save some time and money.

Using your cruise control can save money too. Driving in MN at a constant speed really improves fuel economy. Be sure to only use your cruise control under safe conditions; you can look in your owner’s manual for some good tips on using your cruise control.

Did you know that reducing the weight in your vehicle saves gas? Clean out the trunk or back seat from time to time so that you are not paying to carry a lot of stuff around St. Peter that you do not need in the vehicle. If you live in MN where there is snow and ice, clear it off your vehicle; it adds weight and messes with aerodynamics too.

Another tip is to avoid long idle times, which includes warming it up when you start. Modern engines do not require a long warm up to get going;  just take it easy for a few minutes.

Be sure to get a new gas cap if yours leaks or is worn.

Now, let’s start talking mechanical. Bottom line – the better you maintain your vehicle, the less fuel you will use. It all adds up in a big way. For example, replacing your dirty engine air filter will pay for itself in improved fuel economy before your next oil change – and will keep saving you after that.

A clean, well-maintained fuel system really pays big dividends. A clogged fuel filter wastes gas. So does a dirty fuel system, grimy fuel injectors and plugged up PCV valves. A fuel system service decreases the gas you use, and increases the power, so drivers in St. Peter can’t go wrong with that.

Some of us ignore our Check Engine light. But fixing the problem that caused the light to come on will usually save some fuel as well. It may be a bad oxygen sensor that can really rob your fuel economy.

And, it may be time for a tune-up. Tune-ups should improve your fuel economy. Don’t overlook the routine maintenance items, like scheduled oil changes, transmission and cooling system service. Dirty or low fluids actually use more fuel. Just look at your vehicle manufacturer’s recommended service intervals in the owner’s manual, or ask your Autotronics of St. Peter service advisor for the schedule.

Don’t forget your tires. Underinflated tires waste gas. And if your wheels are out of alignment, you won’t get the fuel economy you need.

None of these things are very complicated or expensive for people in St. Peter to stay on top of. When you maintain your car properly, you save gas today and prevent repairs tomorrow.

A lot of us St. Peter drivers like our vehicles to reflect our personalities. We’re picky about color and body style. We’ll customize anything from floor mats to window tints to license plates. One popular way for MN motorists to customize a vehicle is to get new wheels.

Wheels come in thousands of designs. Custom wheels can add personality, style or sass to a vehicle. Many of these customizations involve getting a bigger wheel.

Fifteen or 16-inch wheels used to be the factory standard, but today, because a lot of St. Peter drivers like the look of larger wheels, many vehicles are available with 17 or 18-inch wheels. Optional wheel packages of 20 inches or more are also available in St. Peter.

If you want to upsize the wheels on your current vehicle, however, you should know it’s not a do-it-yourself project. There are factors involved in ensuring your wheel change doesn’t jeopardize the safety of your vehicle.

First of all, you need to understand rolling diameter. The rolling diameter is the overall height of a tire. If you increase the rolling diameter of your tires when you upsize your wheels, you may have to modify your suspension to make sure the larger tires fit in the space and don’t rub in turns or over bumps. If that’s more work than you’re willing to do or pay for, then you need to maintain rolling diameter when you change your wheels.

It’s not as hard as it sounds. Imagine a doughnut. That doughnut represents rolling diameter, so you can’t make the doughnut bigger. However, you can increase the size of the doughnut hole. That gives you a bigger wheel. Tires with reduced sidewall on larger wheels will preserve your rolling diameter.

Rolling diameter is important because your wheels and tires still need to fit inside the wheel well. Also, your speedometer, odometer and anti-lock brakes are all programmed to work with a specific rolling diameter. You’ll throw off the readings on your speedometer and odometer if you change your rolling diameter. And for your anti-lock brakes to work properly, your rolling diameter has to be within 3% of factory recommendations. While some St. Peter drivers who upsize may not be concerned about meter readings, throwing off the brake system is a serious safety hazard.

Further, many vehicles in St. Peter are now equipped with electronically controlled suspensions. Changing the rolling diameter will negatively affect this system as well, which can lead to a less smooth ride and lower handling performance as well as safety concerns.

Your friendly and knowledgeable Autotronics of St. Peter tire professional may be able to reprogram your vehicle’s computer to adjust for a larger (or smaller) rolling diameter.

So to maintain rolling diameter, you’ll need tires with a shorter sidewall. These tires will be designed to give the sidewalls the strength they need to maintain ride quality. Consider that doughnut again. As the wheel (the doughnut hole) gets bigger, the sidewall of the tire (the width of remaining doughnut) gets shorter. That means the tire holds less air. The sidewalls have to be made stiffer to compensate for the decreased air capacity.

To improve their strength, the shorter tires will also be slightly wider than your previous tires. But this means you’ll have a larger contact patch, or, in other words, a larger area of tire making contact with the road. This can actually increase your handling performance and decrease braking distances. Many MN auto buffs customize their wheels just for this reason—they want the improved performance rather than looks or style. If you drive a truck or an SUV around St. Peter, you might be interested in the extra control an upsized wheel can provide.

Now, that larger contact patch still has to fit inside your wheel well without rubbing when cornering or when bouncing over bumps or potholes on St. Peter roads. This is termed fitment, and you may need a few adjustments so your new wheels will fit properly. You may need spacers so that your brakes will fit inside the new wheels, as well.

Autotronics of St. Peter tire professionals are experts at mounting, adjusting and customizing wheels. They can give you a lot of good auto advice about wheels and tires and how they affect driving performance and car care. They can help you select wheels and tires that will suit your driving needs and habits.

For example, if you drive off-road around St. Peter, you should consider a higher profile tire. This type of tire will protect your rims from damage while you’re bouncing over rocks. Or, if you tow a trailer or haul heavy loads around MN, you’ll want a tire with a load rating equal to your demands. Your friendly and knowledgeable Autotronics of St. Peter tire professional can help you with these types of concerns.

Once you’ve got your new wheels, have your service advisor at Autotronics of St. Peter see if you need an alignment. You don’t want those new wheels and your higher performance compromised by poor alignment. Get the most out of your investment by getting the work done right at Autotronics of St. Peter in St. Peter.

Last but not least, remember tire pressure. With larger wheels, your new tires will hold less air and they’ll need slightly higher pressure. You’ll need to stay on top of preventive maintenance and keep them properly inflated. Be sure to check their pressure at least once a week. If you don’t keep your tires at their correct pressure, they will wear out really fast. It will also affect your braking and handling performance.

So smile and show off your vehicle around MN. Make it all yours. Bumper stickers, vanity license plates, custom wheels — strut your stuff!

If you are a driver in St. Peter and you aren’t currently using synthetic motor oil in your vehicle, maybe now’s the time to consider it. Need more information? Well, synthetic motor oil is a substitute for petroleum based oil.

Synthetic oil doesn’t gel or gum-up like petroleum based oil and it doesn’t vaporize as easily. It protects better in severe driving conditions like stop and go driving around St. Peter, as well as in very hot or very cold conditions. More and more new vehicles are being delivered with full synthetic motor oil, with the recommendation to use synthetic for the life of the vehicle.

Why is this? Synthetic motor oil maximizes engine power and fuel economy. To see why, we’d need a microscope, so we’ll have to settle for using our imaginations.

The molecules of conventional motor oil are long hydrocarbon chains. Synthetic motor oil, on the other hand, has uniform, round molecules. Which is more slippery, a pile of pencils or a pile of marbles?

Synthetic motor oil lubricates better because there’s less friction. That means better wear protection, cooler operating temperatures, more power and better fuel economy. And synthetic oil doesn’t sludge up like conventional oil, so it prevents those small oil passages from clogging up.

Some manufacturers are extending oil change intervals. The added protection of synthetic oil covers you for these longer intervals. Talk with your service advisor about how you drive and see if he thinks you can benefit from synthetic oil. Also ask about the appropriate oil change interval for synthetic, because it may very well be longer than for conventional oil.

Most of us here in St. Peter have a busy life and might occasionally miss an oil change; go ahead, admit it. Since we’re not perfect, doesn’t it make sense to use a motor oil that’s got your back?

Now synthetic oil costs more. But it lasts longer, protects better and increases fuel economy. You’ll likely save money in the long run. If you’re serious about making your car last longer, start using synthetic motor oil right away.

Give us a call to schedule an oil change, or visit us at our Autotronics of St. Peter website.
