Pick up issue,Bad fuel Mileage
If you feel that your car pick is not as it use to be and consuming more fuel then you need to take it to AlRafay for Checkup
If spark plugs are misfiring or performing poorly, your gas mileage will be affected. Spark plugs are responsible for sparking engine combustion. They can't do that if they aren't working efficiently.
Bad Fuel Injectors
Fuel injectors are responsible for injecting fuel into the engine. Should there be a leak then less fuel gets to the engine causing poor gas mileage.
The type of motor oil you use can affect your gas mileage by as much as 12%. Use car oils that are high in friction reduction. Choose either a synthetic or what your owner's manual recommends.
OLD ENGINE AIR FILTER
Engines must suck in air to power vehicles. If your engine air filter is particularly dirty or clogged, your engine won’t be able to “breathe.” To compensate, the older engines would burn more fuel to travel at the same speed. Newer engines may perform more poorly trying to compensate for a clogged air filter.
DIRTY OXYGEN SENSOR
Whereas many older cars use carburetors to ensure the engine receives the proper ratio of air-to-fuel for combustion, all newer cars since about 1996 use oxygen sensors instead. An O2 sensor measures how rich or lean the exhaust gases are that exit your engine and sends a message to your car’s computer to adjust how much fuel enters the engine. A dirty oxygen sensor may lead to incorrect measurements that cause your engine to burn too much fuel, lowering efficiency by as much as 40%
Faulty oxygen sensors are one of the most common causes of a check engine light and will likely need inspecting and possibly replacing before the 100,000-mile mark. Thankfully, O2 sensors are relatively affordable to replace, helping you save on gas and keep your vehicle’s emissions in check.
CLOGGED FUEL FILTER
Fuel filters block contaminants in the fuel from traveling throughout the engine where they could damage fuel injectors and other important parts. A clogged fuel filter can lower fuel pressure and cause your engine to run poorly.
For older cars especially, it’s important that fuel filters get changed approximately every two years or every 30,000 miles. If you suspect a dirty fuel filter to be the cause of your decreased gas mileage, bring your car into your local ALRAFAY Complete Auto Care for a fuel pressure test.
WORN OUT PISTON RINGS
The piston rings in your engine cylinders form a seal against the cylinder walls to create compression. When piston rings become worn out, they aren’t able to create that seal and the engine loses pressure. As a result, fuel efficiency goes out the window.
Engine oil not only helps lubricate the piston rings, it also contributes to fuel efficiency. The best solution is to make sure your car has regular oil changes with the manufacturer-recommended oil type found in your owner’s manual.
BAD IGNITION SYSTEM PARTS
The ignition system includes coils, spark plugs, and wires that are responsible for combusting the air-fuel mixture in the engine. If any of these parts are malfunctioning, it may be causing the engine to misfire. A misfire occurs when the fuel in an engine cylinder does not combust. Since unburnt fuel cannot power your vehicle, this ends up wasting gas and lowering your fuel economy.
You may experience rough idling, stumbling, or an overall decrease in power from the engine if the ignition system is to blame. The most common culprit inside a failing ignition system is the spark plugs.
OLD OR INCORRECT ENGINE OIL
There’s a common myth that older cars should use thicker engine oil to prevent leaks. The thinking goes that since internal seals and gaskets become brittle and shrink with age, thicker oil would be less likely to seep through the cracks.
Specially formulated “high mileage engine oils” can do this by using seal conditioning additives to help older seals become more flexible and do a better job sealing. In addition, the viscosity is slightly increased to help worn piston rings seal better. However, thicker oil actually creates more resistance between engine parts, which lowers fuel efficiency.
The right motor oil is essential to keeping modern engines lubricated and protected. The best thing you can do to keep your car’s gas mileage up is to perform regular oil changes with the type of oil specified in your owner’s manual. High mileage engine oils may help reduce oil leaking and oil consumption but it will take away some of the potential fuel efficiency.
DIRTY MASS AIRFLOW SENSOR
Mass airflow sensors measure the amount of air flowing into the engine. Like an oxygen sensor, the mass airflow sensor sends data to the onboard computer to calculate the correct air-to-fuel ratio in the engine and the computer adjusts fuel injection accordingly. However, a dirty air flow sensor will cause the car’s computer to miscalculate the proper air-fuel mixture, leading to decreased fuel efficiency or even engine stall. Mass airflow sensors should be cleaned with a special cleaning spray.
WORN OR STUCK BRAKES
Not only is it dangerous to drive with worn-out brake parts, but sticky brakes could also be causing your MPG to plummet. A stuck caliper or sticky brake pads, for example, create resistance to your vehicle’s forward motion. Brake drag means your engine must constantly fight with the brakes just to move, causing fuel efficiency to drop dramatically. Be sure to check your brakes regularly — or simply bring your car into AlRafay for a comprehensive brake inspection.
Clogged and Chocked Catalytic Converters
Replacing a clogged catalytic converter can be quite expensive. Thankfully there are two ways to go about fixing a clogged catalytic converter without having to replace it: Cleaning It : Here you try to unclog the catalytic converter.
