Most JEFFERSON CITY residents associate turbochargers and superchargers with hot rods and racing. However, the number of everyday cars and trucks coming to JEFFERSON CITY from the factory with chargers is growing every year. Here's why.


You need three elements for combustion: fuel, oxygen and ignition (spark plug in gasoline engines and compression in diesels). Superchargers and turbochargers deal with the oxygen part of the formula. In the normally aspirated engines JEFFERSON CITY residents are familiar with, air is just drawn in from the outside by vacuum pressure created as the engine runs. Turbochargers and superchargers compress the air that goes into the engine's combustion chamber, forcing in more oxygen. This forced charge of air allows an engine to make more power than a similarly-sized, normally aspirated engine.


So today we have small 4-cylinder turbocharged engines on JEFFERSON CITY streets making more power than a full-sized V8 did 20 years ago – and getting far better fuel economy. And the power on turbocharged six and eight cylinder engines is through the roof.


In addition to power and fuel economy, charged engines deliver benefits for JEFFERSON CITY drivers at higher altitudes. As the air thins with an increase in elevation, there is less oxygen available to burn in the engine, resulting in a significant power loss. Charging forces more air – and oxygen – into the engine, preserving much of the power at altitude. Turbochargers use exhaust from the engine to spin an impeller that compresses the air sent to the engine. Because there is a short time between when you step on the accelerator and the time the exhaust pressure builds up enough to spin the turbo up to speed, there is a short lag in power. To combat this “turbo lag," some use two turbos: a small one that quickly spins up when engine speed is low and a larger one for when the engine is running . Others use a variable vane technology in the impeller to accomplish the same thing.


Superchargers are driven by a belt connected to the engine's crankshaft. There is no lag because charging starts immediately (it doesn't have to wait for exhaust pressure). Superchargers are less efficient for JEFFERSON CITY residents because they require engine power to run the compressor, whereas turbochargers are powered by “free” exhaust. In both types, the air heats up as it is compressed. In some engines it is necessary to cool the air before it goes into the engine. In those engines, the air passes through what is called an intercooler to bring its temperature down to the proper range. An intercooler is like a small radiator and may be cooled by air flow or by liquid coolant.


JEFFERSON CITY owners of superchargers and turbochargers should always use the fuel grade recommended by their vehicle manufacturer. This is important in charged engines because of the extra pressure as the fuel and air is compressed. Using fuel with too low of an octane rating could lead to premature detonation which can cause damage.


Generally speaking, turbochargers and superchargers do not require regular maintenance. But they do wear like any other part in your vehicle and will eventually need repair or replacement. All of your regular vehicle maintenance should be done on schedule – things like oil changes and transmission service and so on.

Your Vehicle's Other Power Plant (Alternator Replacement)

June 30, 2025
Your vehicle's engine is probably the first thing that comes to mind when you think of a power plant. But it has another power source that is vital as well: the alternator. The alternator is what puts out the electricity that powers such things as your lights, power windows, sound system, and navigation. Maybe you've started seeing those electrical components behaving in strange ways. Maybe your power windows are going up and down a little bit more slowly than they used to. Or perhaps your engine doesn't start as easily or is misfiring. Other signs of a failing alternator are headlights that are either brighter or dimmer than usual. If your battery keeps going dead, it could be that the alternator isn't recharging it. The alternator has to get its power from somewhere, and in vehicles with internal combustion engines, that power comes from a drive belt powered by the engine. Sometimes that belt can fail. If you hear a whining sound, it could mean bearings in the alternator aren't turning as freely as they used to. You could even notice a burning smell. Oh, and when you see your battery light illuminated on your dash (it looks like a rectangle with a - and + inside), it may be warning you that your alternator is not healthy. Bring your vehicle in to us for a diagnosis if you notice any of these symptoms. If your alternator is bad, we can recommend a new or remanufactured one to replace it. Some new alternators are warranted for life and remanufactured units usually are guaranteed as well. It's important to your vehicle's health to have its alternator putting out the right power consistently. It may not be as well known as the other power plant under the hood, but it's a vital part of helping your vehicle run the way it is designed to. Contact Frosty's Today!

Will Proper Auto Maintenance at Frosty Auto Clinic Really Save Gas in Jefferson City, MO

May 14, 2025
Have you ever thought about all the little things we do to keep our lives running smoothly - like vacuuming? It makes a room feel fresher and more comfortable. We may not consider that we're also prolonging the life of the carpet by keeping it clean. But JEFFERSON CITY, MO drivers don't always extend those good habits into the garage. Our vehicles need regular maintenance just like our rugs need vacuuming. We may not notice a difference in the feel or appearance of the vehicle, but just as cleaning a carpet carries the hidden reward of prolonging its life, maintaining our vehicles incurs a hidden reward that becomes noticeable at JEFFERSON CITY, MO gas stations. When it comes to reduced fuel economy, there are two culprits: increased friction and inefficient fuel combustion. That means that anything JEFFERSON CITY, MO drivers can do to decrease friction and increase the efficiency of their engines will translate to savings on fuel. Friction increases the amount of energy it takes to move something. So if we can reduce friction, we can decrease the amount of fuel it takes to run our vehicles. Engine oil is usually at the heart of friction problems in an engine. Too little oil means parts are not getting lubricated, which increases friction and dirty oil doesn't lubricate as well as clean oil. So one secret to good fuel economy is to stay on top of oil changes. Don't skip them and don't procrastinate. The same auto advice applies to transmission fluid. Keep it full and keep it clean, and your vehicle will run with less friction and better . If your tires are underinflated, it increases the friction between the tire and the road. Again, there is increased drag, and it takes more fuel to move your vehicle. People in JEFFERSON CITY, MO should check their tire pressure every month and keep their tires properly inflated. Alignment and brake problems can also increase friction. Besides saving fuel, keeping these systems in good repair has the added benefit of saving you on tires and brake pads. These items wear out more quickly when the alignment is off or when the brake system isn't in good working order. Talk to your friendly and knowledgeable Frosty Auto Clinic service advisor. The second culprit that stealthily steals our fuel economy is inefficient fuel combustion, which depends on the engine getting the right amount of clean fuel to the right place with the right pressure at the right time in the right pattern. The key to peak engine performance is to keep the fuel system clean. Varnish and gum can build up in a fuel system, which will interfere with the fuel injectors. The fuel injectors are responsible for all those “rights” we spoke of. If they're dirty, amounts, timing, pressure and spray patterns can all get out of whack. The result? Reduced fuel economy. A fuel system cleaning at Frosty Auto Clinic in JEFFERSON CITY, MO can get your injectors back on track, improving performance and efficiency. There are a few other maintenance items that can improve your fuel economy. One is to replace your PCV valve when it gets sticky. This valve allows unburned fuel in your engine exhaust to return to the engine. JEFFERSON CITY, MO can also replace worn spark plugs and dirty fuel filters. A well-maintained vehicle will require fewer repairs and save money at JEFFERSON CITY, MO gas pumps. Call us today!

PCV Valve Replacement at Frosty Auto Clinic in JEFFERSON CITY, MO

May 14, 2025
The PCV valve is a little, inexpensive part that does a big job for JEFFERSON CITY, MO and our environment here in MO. PCV stands for Positive Crankcase Ventilation. The crankcase is the bottom area of the engine that holds the oil. When the engine's running, fuel is burned to generate power. Most of the exhaust from combustion goes out through the exhaust system. But some exhaust blows by the pistons and goes into the lower engine, or crankcase. These hot gases are about 70 percent unburned fuel. This can dilute and contaminate the oil, leading to damaging engine oil sludge. It can also cause engine corrosion. At high speeds, the pressure can build up to the point that gaskets and seals start to leak. Over time, the vented gases will gum up the PCV valve and it won't work well. That can lead to oil leaks, excessive oil consumption and reduced fuel economy. Fortunately, it's very easy to test the PCV valve, and it's quick and inexpensive to replace at Frosty Auto Clinic in JEFFERSON CITY, MO. Even so, it's often overlooked because many JEFFERSON CITY, MO don't know about it. Check your owner's manual or ask your friendly and knowledgeable Frosty Auto Clinic . If this is the first time you've heard of a PCV valve, you might be in line for a replacement. Please ask us at Frosty Auto Clinic about your PCV valve. For the price of a couple of burger combo meals at your favorite JEFFERSON CITY, MO drive-up window, you can avoid some very expensive deep engine repairs. Give us a call

Timing Belt

April 16, 2025
Let's address a very important maintenance item for everyone in JEFFERSON CITY MO – timing belt replacement. It's important because letting this one slide can lead to very expensive engine damage. Your timing belt choreographs the timing of your combustion process. Your pistons travel up and down in the cylinder. Intake valves open at the right time to let in air and fuel; they close at the right time to allow the fuel to burn and then the exhaust valves open at the right time to let out the exhaust. All this happens thousands of times a minute and it's your timing belt that makes sure the valves are opening and closing at precisely the right time. If the timing is off, your engine won't run. And that's the best case. The worst case is that a valve is opening at the wrong time and collides with the piston. The result is bent valves and maybe even more damage to the cylinder head. Repairs can run several thousand dollars. Now, timing belts just wear out naturally so you want to replace a worn belt before it slips or breaks. Check your owner's manual or with your service advisor at Frosty Auto Clinic in JEFFERSON CITY, MO, to see when they recommend you replace the timing belt. If you've never replaced your timing belt and have more than 60,000 miles/100,000 kilometers on the clock, talk with your JEFFERSON CITY service advisor at Frosty Auto Clinic right away to see if you're due. On some engines, the water pump is driven by the timing belt as opposed to the serpentine belt. If that's the case, it's a good idea to replace the water pump when you're replacing the timing belt and vice versa, since much of the same work has to be done for either. The same is true for the timing belt tensioner – it should be inspected and possibly replaced. Now, replacing a timing belt is one of the more expensive routine maintenance items on your service schedule. But not replacing your timing belt can lead to some of the most expensive repairs you're likely to ever have. Call Us Today.
