Vive la Differential at Franklin Auto Service in Franklin
Posted July 31, 2022 8:20 AM
There are a lot of drivers in Franklin who are due for a differential service, but had never heard of a differential before. With front-wheel drive being so common in MI these days, the differential is just taken care of during a transmission service, so most Franklin folks don't even have to think about it. And rear-wheel drive differentials don't need to be serviced for years, so it's understandable that it's not something on the top of your mind. It's not uncommon for people in Franklin to not know they have a differential, let alone know that it needs service.
To better understand what a differential does, think about a track at any MI high school. There are lanes marked off on the track. For the longer distance races, the starting lines are staggered. The starting lines for the outside lanes are ahead of the starting lines for the inside lanes. That's to compensate for the longer length of the outside lanes. Staggering the starting lines means that each runner has the same distance to run.
The differential compensates for the difference in speeds between the inside vehicle wheel and the outside wheel in a turn, because they have to travel together through slightly different distances.
It's a very important function. When you think of it, all the power to get a vehicle moving goes through the differential. Most cars weigh between 3,000 and 6,000 pounds (1,400 and 2,800 kg) – trucks even more. The power from the engine goes through the transmission and then through the differential to the drive wheels.
That's a lot of work and requires very heavy duty parts. And those parts need protection. The differential fluid lubricates the gears in the differential and keeps them cool. The fluid eventually gets dirty and worn down. Some kinds of differentials require special additives that break down over time. So manufacturers recommend intervals for when to replace your differential fluid.
Your knowledgeable Franklin Auto Service service technician will drain the used fluid and check it out for metal bits, which could be a sign of excessive wear on the gears. He'll then replace the fluid and install the additives if necessary.
Your Franklin Auto Service service advisor can look up the vehicle manufacturer's recommended service interval or you can check your owner's manual.

Franklin Auto Service Service Tip: Why Synthetic Oil Is Good For Your Vehicles
Posted July 24, 2022 7:08 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 Franklin Auto Service in Franklin.)
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 Franklin Auto Service 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.
Give us a call.

Fuel Injection Keeps Getting Better for Franklin Motorists
Posted July 17, 2022 7:07 AMFranklin residents know that engines burn fuel to operate. Fuel is pumped from your fuel tank to your engine where it is squirted—or injected—into your engine's cylinders. This is the function of the fuel injectors.
There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air—and before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the engine.
Direct injection engines burn fuel more efficiently than conventional engines. Some models can deliver the power of a V8 with the economy of a V6.
For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same . The turbocharged version delivers 350 horsepower.
Why the big difference in power? Direct injection systems allow fuel to be squirted into the engine at hundreds of times the pressure of a conventional engine. This atomizes the fuel better (breaks it down into tinier droplets), which means more of it gets burned, which translates to more power for your engine. It also results in cleaner emissions and improved fuel economy.
Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the engine needs it. They are also engineered to inject fuel with a specific spray pattern. This spray pattern allows for maximum fuel efficiency and proper atomization.
Direct injection engines require a much higher degree of precision than conventional engines. For this reason, they are equipped with more sophisticated computers.
When fuel injectors get dirty, their precision drops off. The spray pattern won't be precise, and the timing of fuel delivery may be off. This decreases fuel efficiency and fuel economy for Franklin drivers as well as delivering less power to the engine.
Fuel injectors are not cheap to replace. Direct injection fuel injectors are even more expensive. And we're talking a mortgage payment to buy a set of new fuel injectors for a diesel engine.
So keeping your fuel injectors clean is just good auto advice for Franklin residents. The best way to do this is to change your air and fuel filters regularly and practice other habits of good vehicle care and preventive maintenance at Franklin Auto Service in Franklin. Cleaning additives in your fuel can also help.
If you do end up with gum or varnish in your fuel system, you'll need a professional fuel system cleaning. This will clean out your whole system, including the injectors. The good news is that with proper maintenance, your fuel injectors will last for a long time.

Fuel Saving Tip: Franklin Tune Up
Posted July 10, 2022 7:24 AM
Have you ever gone to listen to an orchestra? The musicians take the stage early and tune their instruments. Each individual instrument must be in tune, but the critical thing is for the entire orchestra to be in tune with each other. That's why they tune up together.
Now this is no surprise; I'm going to relate the orchestra to your vehicle. Your engine has many component systems that each need to be working properly. And the components need to be working in sync, all timed up together in order for the engine to work efficiently.
We call this... (ta-da) a tune-up. When an orchestra's out of tune you get a bad concert. When your vehicle's out of tune you get bad performance and bad fuel economy.
So check your owner's manual for recommended tune-up intervals. Or ask your Franklin service advisor at Franklin Auto Service what he thinks.
...Just be careful not to say you want to make beautiful music together – that kinda makes us uncomfortable.

Emergency Items for Your vehicle
Posted July 3, 2022 8:38 AM
Local Franklin roadside emergencies can range from a flat tire downtown to being stranded in a snowy ravine for three days. So you may want to consider a basic emergency kit to keep in the car at all times and a travel kit tailored to a specific trip.
Your close-to-home kit for around Franklin would have some basic items to work on your car: everything you need to change a tire, gloves, a couple quarts of oil, some antifreeze and water. A can of tire inflator is a great temporary fix for minor flats. You'll also want jumper cables or a booster box, flares, a flashlight and some basic hand tools.
Now for your comfort and safety: a first aid kit, drinkable water, high calorie food (like energy bars), blankets, toilet paper, cell phone, towel, hat and boots. Keep some change for a pay phone, emergency cash and a credit card.
People who live in areas with frequent severe weather or earthquakes may want to carry provisions for longer emergencies.
For trips away from home, consider the weather and geography as you assemble your emergency supplies. You'll need to have a source of light and heat and will want to provide protection against the elements as well as adequate food and water for everyone in the car.
Always tell people where you are going and have a plan for checking in at waypoints. Then if you run into trouble, you can be reported missing as soon as possible and rescuers will be able to narrow the search area.
The key to safe travel is to keep your vehicle properly maintained, plan ahead and let others know your itinerary.
