Engine oil keeps your car running smoothly by lubricating moving parts, reducing friction, and helping to prevent overheating. Neglecting oil changes can lead to decreased performance and costly repairs over time. Understanding the essentials of oil changes can help you maintain your vehicle’s reliability. At Ken’s Muffler & Brakes, we’re happy to answer your questions about oil changes in the greater Dallas area.


How Often Should I Change My Oil?

The frequency of oil changes depends on your vehicle and the type of oil used. Traditional advice often suggested every 3,000 miles, but modern engines and synthetic oils allow for longer intervals, sometimes up to 7,500 or even longer. Vehicle manufacturers provide recommended oil change intervals in the owner’s manual. Following these guidelines helps ensure optimal engine performance and avoids unnecessary wear. 


What Type of Oil Should I Use?

Using the right oil for your vehicle is essential. There are different types, including conventional, synthetic blend, and full synthetic oils, each with unique properties. Full synthetic oils offer superior protection and performance, particularly for high-mileage or high-performance engines, while conventional oils may be sufficient for older vehicles or cars with simpler engines. Viscosity, indicated by numbers like 5W-30, is also critical. Using the correct type and viscosity recommended by your manufacturer protects your engine and promotes smooth operation. 


Can I Drive with Low or Old Oil?

Driving with low or degraded oil can be harmful. Low oil levels reduce lubrication, increasing friction and heat, which can cause engine damage. Old, dirty oil loses its ability to lubricate and protect engine components effectively, leading to potential wear and reduced fuel-efficiency. Checking your oil regularly and changing it on schedule helps prevent these issues and keeps your engine running more efficiently.


Is Professional Service Necessary, or Can I Do It Myself?

While some car owners perform oil changes themselves, professional service offers several advantages. Technicians ensure the correct oil type and quantity are used, safely dispose of old oil, and can perform additional inspections. For those who are not highly experienced with car maintenance, professional service reduces the risk of mistakes and ensures the job is done correctly.

Common Warning Signs of Suspension Trouble You Shouldn’t Ignore

by Ken’s Muffler & Brakes • 10 August 2026
As the miles add up, suspension parts such as shocks, struts, springs, and control arms can wear out due to road conditions and even normal use. Recognizing the warning signs of suspension trouble early can help prevent more serious problems and costlier repairs. At Ken’s Muffler & Brakes, we provide expert suspension repair in the greater Dallas area. Here are five common signs that your vehicle’s suspension system may need repairs. Your Vehicle Rides Roughly One of the most noticeable signs of suspension problems is a rougher ride than usual. If you feel every bump, crack, or dip in the road, your shocks or struts may no longer be absorbing impacts properly. Having your suspension inspected can help identify worn components and restore a smoother ride. The Vehicle Pulls to One Side If your vehicle pulls left or right while driving, it could be a sign of suspension issues. Problems with worn or damaged suspension components can affect wheel alignment and cause uneven handling. A vehicle that does not track straight can make driving more difficult and may create safety concerns, especially at higher speeds. The mechanic can inspect the suspension and alignment to determine the cause. Excessive Bouncing Your vehicle should settle quickly after driving over bumps or dips. If it continues bouncing several times after hitting an uneven area, your shocks or struts may be worn out. Excessive bouncing reduces vehicle stability and can make it harder to maintain control. Replacing damaged suspension components can improve handling. Uneven Tire Wear Appears Suspension problems can affect how your tires make contact with the road, leading to uneven or accelerated tire wear. If you notice bald spots or other uneven tread patterns, the issue may involve suspension components, alignment problems, or both. Ignoring uneven tire wear can shorten the life of your tires and reduce traction. Unusual Noises Clunking, knocking, squeaking, or rattling sounds while driving over bumps may indicate worn suspension parts. These noises can come from damaged bushings, loose components, worn ball joints, or failing shocks and struts. Unusual sounds should not be ignored because they may indicate that a suspension component needs repair or replacement.

What are some of the most frequent check engine light triggers?

by Ken’s Muffler & Brakes • 10 July 2026
The check engine light is one of the most recognizable warning indicators on your dashboard, yet it is also one of the most misunderstood. When it illuminates, it can signal anything from a minor issue to a more serious engine problem. Modern vehicles use advanced onboard diagnostics to monitor engine performance, emissions, and fuel-efficiency, meaning even relatively small faults can trigger the warning light. At Ken’s Muffler & Brakes, we provide expert check engine light diagnostics and repair in the greater Dallas area. Here’s a look at four common check engine light triggers. Faulty Oxygen Sensors Oxygen sensors measure the amount of oxygen in your vehicle’s exhaust to help regulate the air-fuel mixture. When these sensors fail or become contaminated, they can send incorrect data to the engine control module. This often leads to reduced fuel-efficiency, increased emissions, and an illuminated check engine light. Malfunctioning Mass Airflow Sensor The mass airflow (MAF) sensor measures the amount of air entering the engine to determine the correct fuel mixture. If the sensor becomes dirty or fails, it can cause poor engine performance and rough idling, often accompanied by a check engine light. Failing Spark Plugs or Ignition Coils Spark plugs and ignition coils are essential for proper engine combustion. When they begin to wear out, the engine may misfire, run roughly, or lose power. Misfires are quickly detected by the vehicle’s computer system and commonly trigger the check engine light. Catalytic Converter Issues The catalytic converter helps reduce harmful emissions by converting exhaust gases into less harmful substances. If it becomes clogged or damaged, it can lead to reduced performance, increased emissions, and poor fuel-economy. Because it is a key emissions component, problems with the catalytic converter often activate the check engine light.
