Save Money in the Long Run with Regular Maintenance
Our factory-trained mechanics will conduct a comprehensive inspection of your vehicle and perform the necessary steps, from a tire rotation to oil change, to keep it in tiptop shape. Our shop provides the kind of preventive maintenance that will keep your Subaru running smoothly for years.
We are strong believers that the minds who designed your vehicle are the ones most qualified to advise you on how to maintain it. By following the recommended scheduled maintenance provided by Subaru, we can keep your car on the road for many miles to come with the lowest overall cost.
Factory-Recommended Maintenance
Subarus tend to have larger maintenance services recommended every thirty thousand miles. For most people, this is every two to three years. The recommended items tend to be filters, fluids, and spark plugs. And don’t forget about the timing belt. That’s not a good one to miss.
Take factory-recommended maintenance for your Subaru seriously. An ounce of maintenance prevents a pound of repair.

SPARK PLUGS
Spark plugs are parts of the ignition system that naturally undergo wear and tear.
These plugs handle tens of thousands of volts of electricity with every engine cycle. After receiving that electricity, they’re in the combustion chamber where air and fuel mix and combust. This process happens between 400 and 3500 times per minute.
It’s a tough job in your engine’s most challenging environment, and the spark plugs’ electrodes slowly wear away. The more the electrodes wear down, the more energy it takes to jump the electrode gap. This increases the workload for the rest of the ignition system and can cause premature failure.
Worn-out spark plugs lower your vehicle’s fuel economy and cause increased tailpipe emissions. They may also damage the catalytic converter, which can be costly to replace. When completely worn out, they lead to a dead misfire, where the affected cylinder isn’t contributing power.
Save money on fuel and avoid costly repairs by regularly replacing your spark plugs according to Subaru’s car maintenance schedule.
We use factory-recommended NGK spark plugs and wires.

AUTOMATIC TRANSMISSION FLUID & CONTINUOUSLY VARIABLE TRANSMISSION (CVT) FLUID
The core function of the transmission is to allow for a range of gear ratio options between the engine’s speed and the speed of the wheels. While an automatic transmission and a continuously variable transmission accomplish this function in different ways, the role of the fluid in them is similar.
The fluid performs three basic functions:
- Lubrication: it lubricates the transmission to reduce friction between moving parts.
- Hydraulics: it operates as a hydraulic fluid. It is pressurized in certain chambers and lines to initiate different mechanical functions like shifting gears.
- Cooling: it carries heat away from the transmission to the transmission cooler. The heat is dissipated into the air flowing past the moving vehicle.
As the transmission fluid breaks down, it becomes less efficient at performing these tasks. This results in more wear and tear on the transmission, one of the most expensive parts to replace.
Draining and refilling the transmission fluid is one of the most essential scheduled maintenance items. Replace your vehicle’s transmission fluid to avoid a much more costly part replacement.
DIFFERENTIAL FLUID
Subarus are all-wheel-drive vehicles. To get the power from the engine to all four wheels, they require differentials. These are extra mechanical systems that split the energy that comes out of the transmission between the tires.
All-wheel-drive systems require two differentials, one for the front tires and one for the rear tires. When a vehicle turns, the inside tire has to turn slower than the outside tire since it’s traveling a shorter distance. To achieve this difference in turning speeds, differentials have multiple heavy-duty gears.
The differentials are full of oil that coats the gears. When the differential fluid is low, the gears rub against each other, causing a grinding or humming noise. This heats up and damages the gears.
Prevent damage to the gears and bearings with a differential fluid drain and refill service. Simply follow Subaru’s recommended routine maintenance.
MANUAL TRANSMISSION FLUID
Manual transmissions are much simpler than automatic transmissions or CVTs. It performs the same function of determining the ratio of engine speed to wheel speed. However, unlike with automatic transmissions, the driver decides the gear ratio and not a transmission control computer.
Manual transmission fluid has no hydraulic function to perform. Instead, its function is much more closely related to differential fluid. The fluid used in manual transmissions is the same kind.
Like in differentials, when the fluid breaks down, there is excessive heat and friction. When this happens, drivers might have trouble shifting gears and experience shaking, lurching, or sudden jerks. Have your manual transmission fluid regularly replaced during scheduled maintenance to avoid these problems.
COMPLETE VEHICLE INSPECTION – FREE
Information at Subiesmith is always free. When we perform a bumper-to-bumper inspection on your car, you will receive a full report on what we find, good and bad.
Along with the context of how the pending repairs may impact vehicle operation, our best estimates of the timeframes for repairs, and helpful hints and tips to minimize the risk of damage if repairs need to wait.
- No Scare Tactics – We promise that we will present the recommendations with an appropriate level of urgency. If everything is an emergency, nothing is.
- No High-Pressure Sales – Our goal is to equip you with all the information you need to make educated decisions about handling repairs and maintenance on your Subaru. We also include pictures of the concerns on your vehicle so you can see them for yourself. You don’t have to be a mechanic to identify the most important repairs. We will help bridge that information gap.
- No Surprises – As always, any and all prices we provide are “all-included” prices. Even sales tax. No one likes surprise charges when they go to pick up their car.
ENGINE AIR FILTER
The engine air filter filters dust and debris out of the air before it is drawn into the engine. Modern engines have very tight tolerances between internal moving parts, so any foreign material that gets inside may cause significant damage. It’s important that the engine air filter is working properly.
While it’s an important part, it’s a maintenance item we see serviced more often than necessary. You can tell your vehicle needs a new engine air filter by holding your current one up to bright light. If you can still see light through it, it’s fine. If you don’t, it’s time for a new filter.
Prevent damage to your vehicle’s engine with a proper maintenance schedule and have the air filter replaced.
