When to replace air filter

Time to replace Air Filter ?

How to tell if your car air filter needs changing is important because a clean air filter is a necessity for the proper operation of a car. A clean air filter results in improved gas mileage, better acceleration, increased engine life, lower emissions and overall improved engine performance. Not only does an air filter clean the air entering the engine but it also prevents debris from entering the engine and causing damage. For each gallon of fuel the engine burns, it requires up to 10,000 gallons of clean air; thus why the air filter is such an important engine component.

As an air filter becomes dirty, the capacity for it to filter the air going into the engine is reduced. Because of this, the engine is not able to function properly, which may cause numerous drivability issues. Examining and replacing the air filter, as indicated by the manufacturer’s maintenance schedule, is important but often times overlooked.

Symptoms of a dirty air filter vary but will often times include a noticeable decrease in gas mileage. Other symptoms are potential ignition problems cause by fouled spark plugs. A dirty air filter prevents the necessary volume of clean air from reaching the engine which affects the emission control systems of the car; reducing air flow and causing a too rich air-fuel mixture which can foul the spark plugs. Fouled spark plugs can create an engine miss, rough idle and even starting problems. In addition, a too rich fuel mixture increases engine deposits which may even cause the Service Engine Soon light to come on.

A brand new air filter will generally appear white to off white. A visual inspection of an air filter may reveal that the air filter has become darkened or full of debris. A visual inspection can be done by examining the air filter in bright light. However, an air filter can become clogged with dust and even pollen that may not be easily seen. Therefore, most car manufacturers recommend replacement every 12,000 to 15,000 miles regardless of whether or not the air filter appears to be clean. Cars driven in dusty or frequent stop and go conditions will requires a more frequent check and replacement of the air filter.

Changing an air filter is relatively easy and inexpensive. The air filter is located near the top driver’s side of the engine in a rectangular shaped plastic housing that either snaps or screws shut on most new cars. Older cars with carburetors usually have a circular shaped air filter located in a metal housing on top of the engine that fastens with a wing nut. Make certain to use the correct air filter replacement for your make and model of car.

In some situations, a clean air filter will improve gas mileage by as much as 14% and may increase acceleration by up to 11% depending on the make and model of car. This translates to a potential per gallon fuel savings of up to 15 cents. Learning how to tell if your car air filter needs changing will help you keep your car running properly and ultimately save money on gas and repairs.

Oil Product Differences

What are the differences between Synthetic and Conventional Motor Oils ?

Most readers know that synthetic motor oils typically perform better than conventional motor oils in providing protection for your vehicle, but they might not know why.

What’s the real difference between synthetic and conventional oil? Pretty much everything.

Conventional and synthetic oils begin in the ground. But that’s where the similarities end.

Synthetic oil is not only refined but also distilled, purified and broken down into its basic molecules. This process not only removes more impurities from the crude oil but also enables individual molecules in the oil to be tailored to the demands of modern engines. These customized molecules provide higher levels of protection and performance than conventional oils. But the synthetic base oil is only half the story. The correct blend additives must go into the mix to create the oil.

Our Mobil 1™ brand of advanced full synthetic motor oils has a unique, balanced formulation to keep your engine running like new. So what are the benefits of Mobil 1 synthetic oil? Synthetics typically outperform conventional motor oils in providing more protection for your vehicle.

Here’s how all that chemistry translates to the real world.

Synthetic motor oil keeping your engine clean Keep your engine cleaner As oil circulates through your engine it can pick up deposits. Over time, conventional oils can sometimes form sludge, which can reduce your engine’s efficiency and, ultimately, reduce the life of your engine.

Mobil 1™ motor oils contain fewer impurities compared to conventional motor oils and can better resist the formation of sludge thereby preventing deposits from forming in your engine.

Synthetic motor oil for engine wear protection Offer greater engine wear protection Engine parts are in constant contact with each other. They’re also moving at high speeds. In the extreme environment of your engine, components can wear and break down. Your motor oil is the protective barrier between these components. As conventional oils break down, their ability to prevent engine wear diminishes. Mobil 1 motor oils, on the other hand, retain their wear protection properties for a much longer time, increasing engine life.

Mobil 1™ oil in car driving in cold weather with snow on ground and trees Flow better in low temperatures When your car sits for awhile (let’s say overnight) the oil settles.

But, when you fire up the ignition, it begins flowing through critical engine parts to protect against friction. With conventional oils, it takes more time until they are able to flow smoothly through the engine.

During the cold winter months, or if you live in an extremely cold environment, this flow process takes even longer. Mobil 1 motor oils, however, are engineered to flow quickly even at low temperatures, and they start protecting your engine right after you start your car.

Synthetic oil in car protects in desert high temperatures Protect better at high temperatures When running, engines are hot. Really, really hot. Over time, the high temperatures in your engine can cause conventional motor oils to break down or evaporate exposing your engine to wear. Mobil 1 motor oils are engineered to resist these high temperatures, which is especially important if you’re driving in hot climates.

Synthetic oil protects turbocharger engine parts Protect critical turbocharger parts To meet consumer demand, automakers are building cars with smaller engines (for greater fuel efficiency) but adding turbochargers (to boost power). We already mentioned how engines run at high temperatures, which can break down conventional oils faster, but today’s turbocharged engines are even more aggressive. The shaft inside a turbocharger can spin upwards of 200,000 revolutions per minute, so it’s critical that your motor oil can get to that shaft and lubricate it properly very quickly. Conventional oils can break down faster under these conditions and leave deposits on turbocharger components, which can lead to failure. Mobil 1 motor oils can protect these components much better than conventional oils, keeping them operating at peak performance and boosting your engine’s power.
