Every time a vehicle’s driver presses the gas pedal, they are controlling how much fuel and air the engine takes in. The pedal tells the throttle valve how much air to let in and the computer tells the fuel system how much fuel to deliver. These calculated amounts of air and fuel are typically mixed together before being sucked into the combustion chamber of an engine cylinder. There the spark plug ignites the mixture, producing the controlled burn that powers the vehicle. It’s important for the fuel in the vehicle to be as clean as possible.
HOW DO THEY PLUG?
Today’s fuel injection systems operate at optimum efficiency but only under very strict conditions and with microscopic tolerances. Even the smallest speck of dirt, carbon or other deposits can directly affect fuel delivery. The sophistication of these systems is at the heart of why cleanliness is vital, unless, that is, people have money to burn.
Deposits can also build on other delicate system components that will develop into problems. Thus, the intake manifold, valves, combustion chamber, EGR valve, O2 sensor and the catalytic converter should also be cleaned for the vehicle to operate at an optimum level. Deposits on these components will affect the engine’s performance, fuel economy, and emissions.
New vehicles today run as designed: they provide smooth and quick acceleration, great fuel economy, and plenty of horsepower. However, after 5,000 – 6,000 miles, these magnificent engines begin to lose that initial responsiveness and efficiency, and guess why. That’s right – an accumulation of fuel-related contaminants.
Scientifically Speaking, Why Do Deposits Form?
Fuel-related deposits form from a combination of gasoline additives, engine heat and driving habits. A high quality detergent gasoline may help control deposit formation, but the same gasoline also contributes to it. While these detergents work well in most cases, they can cause other problems in an engine, and it’s interesting to follow the dirt trail.
Here’s how it happens. After driving to work in the morning, you park the car and turn off the engine. The gas that remains in the injector tips, intake manifold and combustion chamber quickly evaporates due to residual engine heat. This is called “hot soak.” But not all of the components of the gasoline evaporate. The remaining components – the fuel additives – begin to oxidize. This creates gums and resins that will collect any solids from the combustion chamber or airborne dirt that finds its way into the manifold through the PCV and EGR systems. These minute deposits continue to build up after every engine shut-off until they begin to affect the performance of the engine.
Since the opening of a fuel injector is no larger than the diameter of a human hair, it doesn’t take very long for these deposits to build up and begin restricting the fuel delivery and the spray pattern of the injectors. These deposits also build up in the intake manifold, on the back of the intake valves, inside the combustion chamber, on the O2 sensor and also in the catalytic converter. Airflow is also affected, and a 15% reduction in fuel and airflow can result in a 50% loss in power. That’s 50%!
Fortunately, here are solutions (literally) for all of these fuel-related problems due to deposit build-up — a professional fuel system service like the one Als Quick lube offers. It’s the only way to go to ease the pain of pricey petrol. Clean up the system, restore a vehicle’s optimum operating efficiency and give you a shot at holding on to a little more of your hard-earned money.
What does the two stage Fuel System Cleaning Service do?
Performing the two stage fuel system cleaning service:
The service helps clean the fuel system and combustion chamber with multistage cleaners.
Why is it important?
The fuel filter is located on the line that brings fuel from the tank to the engine. The filter removes contaminants and particulates so fuel can flow to the engine smoothly and without obstruction. A clean, unclogged fuel filter can help prevent reductions in engine performance.
What is the service?
The old fuel filter is removed and replaced with a new one that meets your manufacturer’s recommendations.
While you’re there, let us perform a Touch® Courtesy Check, which includes a visual check of the following items:
Oil change near me? The next time you ask this question, just look to Al’s Quick Lube
Most cars on the road today use multi-grade oil — one that can work efficiently in cold and hot weather. A multi-grade oil is rated by two numbers, such as 5W-30.
About the oil classification system.
Each engine oil comes with a classification indicating its viscosity, which is its friction or resistance to flow. In a multi-grade oil, the first number indicates how the oil will flow when it is cold. The lower the number, the lighter the oil and the better it will perform at lower temperatures. The second number indicates the thickness of that same oil at high temperatures. For example, a 5W-30 oil will flow as a 5-weight oil at zero degrees Fahrenheit and as a 30-weight oil at 210 degrees Fahrenheit
Why viscosity is a concern.
During cold starting, only a small amount of oil is present in the upper parts of engines. To lessen the friction when upper engine parts, such as the valve train, pistons, overhead cam and cam bearings, scrub against each other, a lower viscosity allows the oil to reach the components more quickly.
Why 5W-30 and 5w-20 oils are so popular.
Many vehicles today leave the factory with 5W-30 or 5w-20 engine oil. Vehicle manufacturers recommend them because they are lighter oils that perform well in a range of temperatures and help improve gas mileage.
Not all motor engine oils are 100% petroleum. Synthetic oils, which are primarily chemically compounded lubricants, are also available. They can provide:
Which oil is right for your car?
The simplest and safest way to find out is to check your owner’s manual…or talk to your Midas mechanic.
Oil filters are designed to trap foreign particles suspended in the oil and prevent them from getting to the engine bearings and other parts.
Your vehicle relies on a variety of fluids to operate its brake, steering, transmission, engine cooling and other systems. When these fluids become degraded or are at incorrect levels, damage to other components may occur…so always follow the manufacturer-recommended service schedule.
Automatic Transmission Fluid
This is typically an oil-based fluid used in a transmission that lubricates and cools the transmission and provides hydraulic pressure to shift gears automatically.
This is the hydraulic fluid used to transmit pressure through the brake lines in a brake system providing stopping power and protecting hydraulic brake components from internal corrosion.
This is the mixture of water and antifreeze used in an engine cooling system to dissipate heat and maintain the engine’s temperature throughout its operating range.
Starting & Charging
The battery starts your car, powers on-board computers and supplies emergency power needs. A weakened battery causes stress on alternators and starters, especially during extreme temperatures. Let Midas test and inspect your battery regularly.
Clean air filters can increase engine performance, boost fuel mileage and reduce engine wear. Cabin air filters can minimize airborne contaminants in the passenger compartment and improve heating/cooling efficiency.
