Denver Auto Repair: Engine and Cabin Air Filter Necessities

July 19, 2017

Filters provide a valuable service to your vehicle and although a relatively small part, their specific function is important to quality air circulation. Many motorists will change their residential air filters monthly and according to specific HVAC guidelines. In fact, some homeowners spend big bucks in order to maintain better air quality in their homes. Mancinelli’s, a Denver auto repair shop, wants you to provide the same care inside your vehicle.

During a typical workweek many individuals will spend 10-plus hours inside their car, if not more. With the inclusion of weekends, almost an entire day of the week could possibly be spent inside your automobile. When you consider the amount of time spent behind the wheel or as a passenger, the quality of the air being circulated throughout the cabin becomes more important.


The car’s cabin air filter “cleans the air that comes into the interior through the heating, ventilation and air-conditioning system. It catches dust, pollen and other airborne material that can make riding in a car unpleasant, particularly if you have allergies or other respiratory problems.”

Similar to a home air filter the vehicle owner’s guide should provide estimated mileage points for replacement. Depending on your driving environment, conditions, and amount the timing could be increased or decreased based on use.

Average estimates are between 12,000 and 15,000 miles or every two to three oil changes. Even if clear of debris, often the filter needs to be replaced after considerable use in order to prevent further damage, future repair cost, and provide the optimum air quality into a vehicle’s cabin.


Similar to the cabin air filter, engine units provides the same service in order to protect the vehicle’s cylinders and keep the car running smoothly. After time sand, dirt, bugs, twigs, leaves, and all sorts of debris creep under the hood and work their way around the engine but are prevented from entering important spaces by the air filter. These components build up outside the filter until replacement is necessary.

Most engine air filters should be changed between 15,000 and 30,000 miles for optimal performance. If a vehicle accumulates less mileage, the filter should be checked and likely changed every three years. This prevents deterioration, keeping the filter itself from falling apart and landing inside the engine’s cylinders.

Both filters serve important roles inside an automobile and represent components general motorists do not consider due to being a secondary component to the overall function of the car. Despite a somewhat limited but specific role, all drivers should keep in mind the importance of air quality in both the cabin and vehicle engine during ownership.

The experts at Mancinelli’s Auto Repair Center are MACS certified meaning they have been specifically trained in the operation and repair of automobile AC systems, including cabin and engine air filter replacement. A full review and inspection of your automobile will be completed in a timely manner, keeping the air circulating through your car clean and clear.

Denver Auto Repair Shop Offers Tire Rotation Benefits

July 12, 2017

Replacing the tires on any automobile is one of the most expensive services required to ensure your vehicle runs smoothly and efficiently. While many owners elect to wait until their four tires will not pass inspection in order to replace them, there are many steps one can take to ensure their tires last appropriate amounts. One of the most critical for regular car service and proper tread wear involves routine tire rotations.

Regular tire rotation helps to extend the life of your tires. Most companies recommend tire rotations occur between 6,000 and 8,000 miles making the intervals similar to that of routine oil changes. For these reasons, rotation of the tires during oil changes and other regular services typically are performed simultaneously.

While rotation of the tires ultimately leads to increased performance, improved tread wear, and optimum driveability the patterns are diverse depending on the vehicle type.

Front-Wheel Drive

Automobiles operating with a front-wheel drive system follow a different rotational pattern than other types. For front-wheel drive options the front two tires should be removed and placed on the back of the same side. For example, the driver’s side front left tire becomes the driver’s side rear left tire during a rotation and vice-versa. However, the back two tires cross the vehicle. The original driver’s side rear tire is moved to the passenger side front.

Following this recommended rotational pattern a vehicle will undergo three changes before returning to its’ original location. By moving the tire around the vehicle, proper tread wear and performance will be utilized.

Rear-Wheel Drive

The rear-wheel drive pattern is exactly opposite that of the front-wheel drive system. During the initial rotation a driver’s side front tire moves across the vehicle becoming the passenger side rear tire. Both back tires are then simply moved up to the front on their corresponding sides.

Again, four rotations occur when a tire returns to the original starting position.

Four-Wheel Drive

For four-wheel drive vehicles tires will always cross the automobile during a rotation. The front driver’s side tire becomes the passenger rear tire and vice-versa. All tires move across and up or back depending on their initial placement.

During four-wheel drive rotations each tire returns to its’ original location during every other rotation. Due to the drivetrain difference a special pattern for four-wheel drive vehicles is a necessity.

Each of these various rotation patterns will help to maintain optimum vehicle performance while assisting in both the alignment and balance of the auto. Further, often tire manufacturers have set guidelines in place to ensure their warranties remain intact, many of which involve regular rotations.

The experts at Mancinelli’s Auto Repair Center can assist you with a tire rotation for your vehicle during a routine inspection or by special appointment. Both you and your automobile will receive first-class care as all service will be completed by one of the many ASE certified technicians on hand to assist you. Don’t wait until it’s too late as most services can be administered the same day so request an appointment online or call 303-778-9761 for quality car care.

Denver Car Repair Discusses Gasoline and Diesel Engines

July 5, 2017

The development of the automobile is an interesting tale that throughout time has translated from actual horse-drawn carriages to fictional horses under a hood. Every year it seems the technology is changing and vehicles come equipped with more horsepower powered by better fuel economy. Auto shops and car repair locations are continually educating themselves in order to keep up with the newest trends and mechanics of every make and model.
New fuel options are becoming more readily accessible to car owners, including E-85 ethanol and even natural gas but two remain dominant in the industry. Both gasoline and diesel fuels have dominated the industry since the beginning and are likely to continue their stronghold despite efforts for decreased emissions and increased fuel economy.
These two fuels have provided consistent service and ready availability throughout history as mother nature provided the basis for each. But concerningly, fossil fuels and crude oil are a nonrenewable resource meaning once the earth’s supply has expired, no new elements will be available. For these reasons, scientists and others have been searching for a more sustainable option, but for the foreseeable future both gasoline and diesel will continue to dominate.
Both operate on a four-stroke combustion cycle but the steps and application of air and fuel are exchanged. These strokes have been detailed by Marshall Brain of
  • Intake stroke -- The intake valve opens up, letting in air and moving the piston down.
  • Compression stroke -- The piston moves back up and compresses the air.
  • Combustion stroke -- As the piston reaches the top, fuel is injected at just the right moment and ignited, forcing the piston back down.
  • Exhaust stroke -- The piston moves back to the top, pushing out the exhaust created from the combustion out of the exhaust valve.


Gasoline engines operate in an exact opposite fashion from their diesel counterparts. The gasoline is first mixed with air and compressed by the pistons prior to being ignited by sparks from the spark plugs.
This powers the engine and makes the car function properly. Gasoline normally comes in three available octane levels at most every fueling station. These include 87-Unleaded, 89-Plus, and 91-Premium with each offering a slight difference between regular and premium. A more efficient and cleaner burn inside the combustion chamber increases with each octane level and as a result, each step also includes a slight cost increase.


Opposite of gasoline engines, diesel motors first compress the air prior to injecting the fuel. Often viewed as a more efficient method of combustion, diesel engines typically will last two-times longer than a gasoline version.
In cars, diesel engines often record greater miles per gallon than gasoline petrol but fuel management for trucks is a different issue. Often the difference between cost per gallon and fuel economy will be negated when dealing with medium to heavy duty trucks with gasoline versus diesel engines.
The experts at Mancinelli’s Auto Repair Center can help whether your vehicle’s engine is powered by gasoline or diesel fuel. Both you and your automobile will receive first-class care as all necessary inspections or service will be completed by one of the many ASE certified technicians on hand to help you.

Denver Auto Center Tips: Top 3 Things Car Owners Forget to Check Before A Summer Road Trip

June 28, 2017

Summer is here and it’s a time where many people hit the road and travel throughout the beautiful state of Colorado. There are many things to do during the summer and practically all of them require a car, one of the integral parts of an adventurous summer. So before you pack the car full of camping gear and drive west, make sure you follow these tips from your Denver auto maintenance shop to keep your car moving for all your summer adventures.

Motor Oil & Other Fluids

Oil is a critical substance needed for a functional engine. It keeps your car motor from being damaged by keeping it cool and lubricated. Without oil, your car is sure to overheat in the hot summer weather and your motor could be damaged beyond repair. Before heading out for your next road trip, make sure your motor oil is clean and at the right level. If you’re not sure how to check your oil - take it to a local auto shop in Denver and they can help.

It is recommended that you change your oil every 3,000 to 5,000 miles, but don’t just wait until you have driven 5,000 miles before you check your oil. Check it before any long car trips or generally once a month. Sometimes leaks can happen and you want to be prepared.

While you’re checking your oil - feel free to check your coolant, power steering fluid, brake fluid and windshield washer fluid. If you’re unsure about how to check these or where to check for them, ask your local mechanic. Learn more about car care tips - five fluids to check.

Tire Pressure

One important, and often overlooked component to car safety is tire pressure. Make sure you take the time to look at your tires and test the air pressure. If you need to get them filled up, your local Denver car repair center will take care of this for free or you can head to a local gas station and do it yourself. It’s best to take the time before a long road trip to make sure your tires are full and wearing properly. Often, tire wear patterns can tell a story. If your car alignment is off or other issues. The worst situation you can find yourself in is with a flat tire or a blown out sidewall, miles away from a mechanic. Many cars only have a spare donut tire, which caution driving under 50 mph for safety precautions.  

Keep in mind, the front of your car bears the most weight so the tires in the front might appear as though they have less air in them. Keep a tire pressure gauge handy in your glove box for peace of mind.   

Car Lights

Another component that car drivers overlook tend to be their headlights and taillights. These components of a car are extremely important for safety of you and your fellow drivers on the road. If your brake lights or blinker lights are burnt out, this can cause confusion on the road and could lead to an unwanted accident. Make sure these lights are working properly before hitting the road both in urban and rural environments.

Headlights are more visible to drivers since they are in front and help you see when the sun goes down. While driving on mountain roads at night, your headlights are extremely important. Make sure they are working properly and aren’t foggy. Many car headlights experience haziness and need to be polished to ensure proper function.

As you can see, auto maintenance is an ongoing operation. If it’s not interesting to you or you just can’t find the time, it’s important to work with your local mechanic. Mancinelli’s Auto Repair Center can help with all of these functions! Locally owned and operated on Logan and Speer for over 50 years, we are your go-to auto repair and car maintenance center in Denver. Contact us today at 303-778-9761.

The engine air filter is an often overlooked part when considering routine car maintenance. However, it’s ability to provide clean air to the engine intake can increase fuel efficiency by as much as 10-percent.
For this reason, the air filter should be either cleaned or replaced regularly to ensure the engine is running properly. Also, proper functionality will ensure greater gas mileage.

Vehicle Alignment

Likewise, drivers can ensure their vehicles continue functioning properly with regular tire alignments. Typically, alignments occur when new tires are utilized or at various mileage intervals.
Proper alignment, which can be easily checked, will benefit the fuel efficiency of any automobile.

Tire Pressure

Similar to tire alignment, ensuring each of a vehicle’s four tires is properly inflated can help to avoid repair fees later down the road. A portion of automobiles are currently running on underinflated tires leading to a loss in fuel economy.
