Full Synthetic Oil Change and Conventional Oil Change for Fall Maintenance

As the weather cools down and the days get shorter, fall is the time to get your vehicle in shape for the colder months ahead. Whether you’re running a commercial fleet or just keeping your personal truck reliable, routine maintenance now can save you serious trouble later. At KG Truck & Auto, we offer both full synthetic oil changes and conventional oil changes as part of our fall maintenance checks. We also provide heating system inspections, wiper replacements, and more to help you prepare for winter.

Why Fall Is the Right Time for Preventive Maintenance

Maryland winters are unpredictable. Cold snaps, road salt, heavy rain, and long idle times are all hard on engines. Getting ahead of the weather now puts your vehicle in a better position when the temperature drops and your schedule tightens.

What’s the Difference Between Full Synthetic and Conventional Oil?

Full Synthetic Oil

Full synthetic oil flows better in cold starts, handles higher temperatures, and lasts longer between changes. It’s a great option for diesel trucks, work fleets, or high-mileage vehicles.

Conventional Oil

Conventional oil is a good fit for older vehicles. It’s more budget-friendly but needs to be changed more often. It works well for light-duty driving and short trips.

Not sure which one your vehicle needs? We’ll check the manufacturer’s guidelines and ask how you use your vehicle day to day.

What’s Included in Every Oil Change

No matter which oil you choose, our oil change service includes:

• Full drain and refill
• A new, high-quality oil filter
• A visual check for leaks
• Fluid top-offs
• Belt, hose, and air filter inspection

Why Full Synthetic Oil Is a Smart Choice for Cold Weather

Full synthetic oil performs better when temperatures drop. It holds its viscosity in freezing conditions, which means it flows faster through your engine on cold starts. That helps reduce wear and tear during the first few minutes of operation, which is when most engine damage happens. It also resists breaking down under stress, making it a better match for trucks that tow, idle in traffic, or run diesel engines. 

If you’re putting serious miles on your vehicle this winter, full synthetic gives you better protection when it matters most.

When Conventional Oil Still Makes Sense

Not every vehicle needs synthetic. For older trucks or equipment that don’t see long hauls, heavy loads, or extreme temps, conventional oil still holds up just fine. It provides the basic lubrication needed to protect your engine during everyday driving, especially if you’re sticking to short local routes or only putting on a few thousand miles a year.

It’s also a good fit for older engines that were designed around traditional oil formulations. The main trade-off is that it doesn’t hold up as long under stress or heat. That’s why you’ll need to stick to shorter oil change intervals, typically every 3,000 to 5,000 miles, to keep everything clean and running smooth. For budget-conscious drivers or low-mileage vehicles, conventional oil still gets the job done.

When to Book an Oil Change

We recommend:

• Every 5,000 to 7,000 miles for full synthetic

• Every 3,000 to 5,000 miles for conventional

• More often for fleets, diesels, and vehicles that idle heavily

Fall is the best time to knock it out before cold weather kicks in.

Add-On Fall Maintenance Services

Heating System Check

We inspect your heater core, blower motor, and coolant lines to make sure your cab warms up quickly and stays warm.

Wiper Replacement

Bad wipers are useless in a storm. If yours are streaking or splitting, we’ll swap them while we’ve got the hood open.

Battery and Charging System Test

Cold weather kills weak batteries. We’ll test your battery, alternator, and starter so you don’t get caught off guard.

Tire Pressure and Tread Check

When temperatures drop, so does your tire pressure. We check PSI and tread depth so your truck keeps traction when the roads get slick.

Coolant and Antifreeze Inspection

Low or dirty coolant puts your engine at risk. We check levels, look for leaks, and top you off with the right mix for winter.

Light Check and Bulb Replacement

Shorter days mean more time driving in the dark. We’ll check all your lights, headlights, brake lights, markers, and replace any that are burned out or dim.

DEF System Check (for Diesel Fleets)

Colder temps can mess with DEF tanks and heaters. We check for fault codes, inspect tank heaters, and make sure your emissions system is ready for winter routes.

FAQ: Oil Changes and Seasonal Maintenance

How do I know if I need a full synthetic oil change?

If you drive long distances, idle often, tow heavy loads, or run a diesel, full synthetic oil is generally the better choice.

Can I switch from conventional to synthetic oil?

Yes, most modern engines are compatible. We’ll help you make the switch the right way if it’s a good fit for your vehicle.

How long does an oil change take?

Most oil changes take 30 to 45 minutes. If you’re adding fall maintenance services, expect a little more time.

Do you service fleets?

Absolutely. From HVAC vans to diesel delivery trucks, we keep fleets of all sizes on the road and in rotation.
