Is Your Ford Due for an Oil Change?

As a Ford owner, knowing when to get an oil change is essential for preserving your engine's health. But how do you know when it's time to visit your Ford dealer for a service? Once upon a time the common wisdom was every three months or 3,000 miles. Those days, however are long gone. Most vehicles made in the past couple of decades average around 6 months or 6,000 miles for oil changes, but every car is unique. Here’s how to determine whether your Ford is due for an oil change.

Is Your Ford Due for an Oil Change? Here's How to Tell

Newer Ford models are equipped with the Intelligent Oil-Life Monitor (IOLM), which takes the guesswork out of oil service intervals. This advanced system monitors your driving habits and operating conditions and calculates the percentage of oil life remaining. You will get an alert on the dashboard when it's time to change the oil.

If your Ford is an older model that doesn't have the IOLM system, consult your owner's manual for recommended service intervals. Also, watch for these signs that indicate your vehicle needs an oil service:

  • Dark or dirty oil
  • Illuminated check engine light
  • Unusual engine noises
  • Excessive exhaust smoke
  • Oil smell inside the car

Change the oil as soon as you notice these signs to keep the engine running smoothly.

Benefits of Timely Oil Services at Your Ford Dealer

Lubricate the Engine

Fresh oil provides essential lubrication for your Ford's engine components. It creates a protective film between moving parts, reducing friction and wear. As the engine operates, this lubrication allows the pistons, valves, and other parts to move smoothly within the engine block. This prevents unnecessary strain and potential damage.

Cool Down Engine Parts

Oil plays a critical role in regulating engine temperatures. As it circulates through the system, it absorbs heat generated by moving parts. This heat transfer helps prevent overheating and maintains an optimal operating temperature.

Get Rid of Sludge Buildup

Over time, oil collects dirt, debris, and metal particles as it circulates through the engine. This accumulation can lead to sludge buildup, which clogs vital engine parts and reduces efficiency. Sludge also prevents the oil from properly lubricating and cooling down the engine. Changing the oil removes the old, sludgy oil along with dirt and other contaminants, keeping the engine clean.

Optimize Engine Performance

An oil service allows your Ford's engine to operate at peak efficiency. It reduces internal friction, ensures smooth component movement, and helps maintain proper combustion. This translates to better fuel economy, improved acceleration, and smoother operation. If you use your Ford for towing and off-road adventures, timely oil services will help maintain optimal capability.

Extend the Life of Components

Changing your engine oil regularly can extend the lifespan of your engine's components. If your Ford is running on old oil, there will be premature component damage due to increased heat and friction. Fresh oil provides superior protection against wear and tear, reducing the likelihood of premature component failure. This can save you from costly repairs and help maintain your Ford's value over time.

When you change your engine oil on time, you are taking an important step in preserving your Ford's performance and longevity. Contact Auffenberg Ford North in O'Fallon, IL to schedule an oil service today!

Ford Maintenance Tips to Keep Your Vehicle Summer-Ready

Summer heat puts real stress on your vehicle. From scorching pavement to long road trips and stop-and-go traffic, the warmer months can take a toll on even the most reliable Ford. Staying on top of Ford maintenance before and during the summer season helps you avoid unexpected breakdowns and keeps your ride performing at its best. The combination of heat and humidity makes seasonal upkeep more important than ever. If you drive a Ford F-150, a Ford Explorer, or a Ford Bronco, a few proactive steps can save you a lot of trouble down the road. Check Your Cooling System One of the most critical things to watch during summer is your cooling system. High temperatures cause your engine to work harder, and if your coolant levels are low or your radiator isn't functioning properly, overheating becomes a real risk. Have your coolant flushed and refilled according to your owner's manual schedule. Also inspect hoses and belts for cracks, swelling, or any signs of wear. These components can degrade faster in extreme heat and are worth checking before summer kicks into full gear. Inspect Your Tires Hot pavement raises tire pressure, which can increase your risk of a blowout if your tires are already overinflated or worn. As part of your summer car care routine, check tire pressure at least once a month and always when tires are cold for an accurate reading. Also look at your tread depth and overall tire condition. Uneven wear could point to alignment or suspension issues that are worth addressing before a long summer drive. Rotating your tires regularly extends their life and keeps handling consistent. Test Your Battery and Electrical System Extreme heat is actually harder on car batteries than cold weather. Heat accelerates the chemical reactions inside a battery, which can shorten its lifespan significantly. If your battery is more than three years old, have it tested. Your Ford's electrical system including the air conditioning compressor works overtime during summer months. A weak battery combined with heavy A/C use is a common recipe for getting stranded. A quick test at your local service center can tell you whether your battery is still holding a strong charge. Change Your Fluids and Filters Ford summer car care isn't complete without a look at your fluids and filters. Engine oil, brake fluid, transmission fluid, and power steering fluid all play a role in keeping your vehicle running smoothly. Heat causes fluids to break down faster, so staying current on your service intervals is especially important in summer. Your cabin air filter and engine air filter should also be checked. A clogged filter reduces airflow and makes your A/C system and engine work harder, which can hurt both comfort and fuel efficiency. Use Ford Mobile Service and Ford Pickup and Delivery Ford makes it easy to stay on top of maintenance without rearranging your schedule. Ford Mobile Service (where available) allows certified technicians to perform many routine services at your home or workplace. Ford Pickup and Delivery (where available) lets you hand off your vehicle from a location that's convenient for you.

2026 Ford Trucks That Handle Travel Trailer Duty

Towing a travel trailer is not just about big numbers. It is about control, stability, and choosing a truck that matches what you plan to pull. The 2026 Ford lineup covers a wide range, from light-duty setups to serious heavy hauling.

That is more than enough for most travel trailers, especially in the mid-size range. Step up to the 2026 Ford Super Duty® lineup, and you are looking at towing capabilities exceeding 40,000 lbs. when properly equipped, which is where larger trailers and fifth-wheel setups come into play. Knowing your trailer weight, including gear, is the first step. From there, it becomes much easier to choose the right truck. Towing Tech That Makes a Difference Ford does not just rely on engine output. The technology built into these trucks makes towing easier, especially if you are not doing it every day. Ford Co-Pilot360™ adds driver assistance features that help keep everything stable on the road. Pro Trailer Backup Assist™ is one of the standout tools, making it far less stressful to reverse with a trailer. Instead of fighting the wheel, you guide the trailer with a dial and let the system handle the steering inputs. Integrated trailer brake controllers and hitch guidance systems also help smooth out the process. Hooking up, maneuvering in tighter spaces, and managing stops all feel more controlled, which is exactly what you want when pulling extra weight. F-150®: The Go-To for Most Travel Trailers The 2026 Ford F-150® is where most buyers will land. It offers a range of engine options, including a hybrid setup, and strikes a strong balance between power and everyday comfort. It is capable enough for most travel trailers while still being easy to live with during the week. That matters if this is your only vehicle.

It is not built for large trailers, but it works well for smaller setups like lightweight campers or utility trailers. Its compact size makes it easy to drive and park, especially in town, and the available hybrid powertrain keeps fuel use in check. For drivers who want to tow occasionally without committing to a full-size truck, it is a practical option.
