Darrell's Firestone Service Tip: Why Synthetic Oil Is Good For Your Vehicles

Posted October 31, 2021 9:11 AM

Hello MI! Today's vehicle care topic is: Synthetic Oil vs. Petroleum Based Oil. Synthetic motor oil is a substitute for petroleum based oil. If you aren't currently using it, why not? Synthetic motor oil maximizes engine power and fuel economy. To see why, we'd need a microscope, so we'll have to settle for using our imaginations. The molecules of conventional motor oil are long hydrocarbon chains. Synthetic motor oil, on the other hand, has uniform, round molecules. Which is slipperier, a pile of pencils or a pile of marbles?

Synthetic motor oil lubricates better because there's less friction. This results in myriad benefits: better wear protection, cooler operating temperatures, more power and better fuel economy. And synthetic oil doesn't sludge up like conventional oil so it prevents those small oil passages from clogging up. (We see that too often at Darrell's Firestone in Farmington.)

Some manufacturers are extending oil change intervals for many models. The added protection of synthetic oil covers you for these longer intervals. Talk with your Darrell's Firestone service advisor about how you drive in and see if he thinks you can benefit from synthetic oil for your vehicle. Also ask about the appropriate oil change interval for synthetic, because it may very well be longer than for conventional oil.

Most of us have a busy life and occasionally miss an oil change; go ahead, admit it. Since we're not perfect, doesn't it make sense to use a motor oil that's got your back?

What about price? Petroleum based oil may appear to win out on this point, but let's consider all the facts. Although synthetic oil costs more, it lasts longer, protects your vehicle engine better and increases fuel economy. You'll likely save money in the long run. If you're serious about making your vehicle last longer, consider using synthetic motor oil.

Why Wheel Balancing and Tire Rotation Save You Money on Tires

Posted October 24, 2021 11:19 AM



Farmington drivers want their tires to last as long as possible. Two ways to extend tire life are wheel balancing and tire rotation.

When wheels are out of balance, they wobble and vibrate. That makes the tires wear in a cupping pattern. If a front wheel is out of balance you'll feel it in the steering wheel. If it's a rear wheel you'll feel it through your seat. To fix this, your technician at Darrell's Firestone puts weights on your wheels to balance them out.

That brings us to tire rotation. The front tires on a vehicle wear out faster than the rear tires. As they push through turns, the shoulders of the front tires wear down. So rotating front and rear tires allows them to all wear at about the same rate over the life of the tire.

Proper tire inflation will also help Farmington folks' tires last longer. Underinflated tires wear more on the shoulder and may even overheat. This could cause tire damage or a blow out. Overinflated tires wear too fast in the middle.

Four-wheel-drive trucks and SUV's tend to wear their tires more unevenly so rotation is even more important with them. Give Darrell's Firestone a call to get our recommendation for your vehicle.

See your owner's manual or ask your service advisor at Darrell's Firestone for your recommended tire rotation schedule. It's usually every 5,000 to 8,000 miles, or 8,000 to 13,000 km.

Tires are among the most important safety components on your vehicle. Take care of them and they'll take care of you.

Automotive Tips from Darrell's Firestone: Making a Battery Last Longer

Posted October 17, 2021 10:11 AM

One thing all Farmington drivers can do to extend the life of their battery is to keep it clean. A greasy, dirty battery holds in damaging heat. Same goes for removing corrosion from the terminals. Darrell's Firestone can help maintain your battery.

Allowing your battery to be deeply depleted – like from using your headlights when the engine is off – is very harmful to your battery. Most automotive batteries can only take that about 10 times before they are ruined.

Also, making sure you have a full charge every month or so extends battery life. Either an extended drive at freeway speeds around the Farmington are or using a battery charger will preserve your battery’s ability to hold a full charge.

Your Biggest Fan (Radiator Fan Problems)

Posted October 10, 2021 9:44 AM

Your vehicle's engine makes a lot of heat when it's powering you down the road, so it needs a way to get rid of that energy.  That's why your vehicle has a cooling system, complete with a radiator and one or two radiator fans, also called cooling fans.  Those fans make sure air keeps moving across the radiator so that the heat stored in the coolant can be dissipated outside when the vehicle is stopped or not traveling fast.

Radiator fans can develop problems and can stop working properly or stop working altogether.  Some signs to look for? If you're driving slowly and idling and you see your temperature gauge moving toward the red or hot zone, that could spell trouble.  Another thing you may notice when a radiator fan is failing is that there may be a loud noise coming from the engine compartment.

There are two types of radiator fans.  One is mechanically connected to the engine and uses the engine's rotational energy to turn it.  The other is an electric fan and is the type used in most newer vehicles.  In the electrical type, one of the components, such as a relay or fuse, may fail, causing the fan to stop turning.  In the mechanical type, since it's driven by a pulley/belt mechanism, one of those components may break or stop working properly.  A clutch can wear out or a belt may slip or break. 

When your cooling fan isn't working properly, it may cause your engine to overheat which could lead to expensive damage. That's why it's important to make sure you visit your service facility if you notice any of these symptoms.  A technician is trained to diagnose the problem and make sure your radiator fan is doing its job.  When it comes to your vehicle, your radiator fan really is your biggest fan.

Fresh Air Inside Your Car in Farmington

Posted October 3, 2021 12:09 PM

Air quality has certainly become a hot issue in our modern world. We install air filters on our ventilation systems and in our vacuum cleaners. There's a filter that cleans the air going into our vehicle's engine — so why not one for the air in the passenger compartment?

Foreign and domestic vehicle manufacturers haven't been ignoring the issue. Cabin air filters are becoming a standard feature on newer vehicles. These filters can clean particles out of the air down to three microns, which accounts for pollen, dust and most pollutants. Farmington residents who suffer from allergies or have a respiratory disorder should be a lot more comfortable. And even if you don't have a medical need for the filter, the cleaner air in your car just might help you breathe better, figuratively as well as literally.

Cabin air filters are still fairly new in the Farmington area, so you'll have to check your vehicle owner's manual to see if you have one. If you do, your routine car care will have to include changing the filter as part of your preventive maintenance. The owner's manual will give recommendations on how often the filter has to be changed, but if the air where you live in MI is particularly dirty or if you're prone to hay fever, you may want to change it more often.


Your friendly service advisor at Darrell's Firestone can also offer suggestions on how often to change your cabin air filter in your Farmington area. They're the ones who actually see the dirty filters, after all.

There is no standardized location for cabin air filters. Farmington residents can usually find them in the vehicle engine compartment or under the dashboard, but they might be somewhere else. So the ease of changing the filter will depend on its location. Some are readily accessible, but others make you wonder how they got installed in the first place. Bring your car into Darrell's Firestone and we will locate your cabin air filter for you.

However, if you have a newer vehicle, it's good auto advice to find out if it has a cabin air filter. If it does, you should change the filter regularly. A sure sign that a filter needs to be changed is that the interior of your vehicle will start to smell bad. That smell is exactly how some Farmington drivers discovered that they had cabin air filters in the first place!

Cabin air filters are just one more way we have to stay safe, stay healthy and stay on the road in MI.
