Dee's Auto Care • January 30, 2026

Welcome to Dee’s Auto Care, your premier destination for expert automotive services in La Crosse, Onalaska, WI, and Winona, MN. As your trusted partner in maintaining your vehicle’s health, we’re here to guide you through understanding one of the most critical aspects of car care—oil changes.

Regular oil changes are essential for preserving engine longevity, enhancing performance, and boosting fuel efficiency. At Dee’s Auto Care, we believe knowledge is empowerment, and we’re excited to share key insights into why oil changes are crucial for your vehicle's well-being.

Why Oil Changes Matter

Oil is the lifeblood of your engine. It provides essential lubrication, reduces friction, removes sludge, and cools down engine components. Over time, however, oil degrades, thickens, and loses efficiency, necessitating regular changes to keep your engine running smoothly.

When to Change Your Oil

Vehicle manufacturers often recommend an oil change every 3,000 to 5,000 miles, but this can vary based on driving conditions, vehicle age, and oil type. We recommend consulting your vehicle’s manual or speaking with our experts at Dee’s Auto Care to identify your car’s specific needs.

Signs Your Car Needs an Oil Change

While mileage is a good indicator, your car often provides physical clues that an oil change is due. Look out for these telltale signs:

  • Unusual Engine Noise: Increased engine noise or knocking could mean the oil isn’t lubricating enough.
  • Dark, Dirty Oil: Fresh oil is typically a transparent amber color. Dirty oil will appear darker and thick.
  • Warning Lights: Don’t ignore check engine or oil change lights on your dashboard.
  • Exhaust Smoke: Excess smoke from the exhaust could indicate an oil-related issue.

Choosing the Right Oil

At Dee’s Auto Care, we help determine the best type of oil for your vehicle. Engine oils come in varying viscosities and formulations—synthetic, synthetic blend, high mileage, and conventional. Your choice can affect overall engine performance significantly.

Benefits of Professional Oil Changes

Though some might consider DIY options, professional oil changes offer unmatched benefits. At Dee’s Auto Care, our trained technicians provide comprehensive checks, including fluid top-ups, filter checks, and a meticulous examination of your vehicle’s essential components.

Environmentally Responsible Practices

Handling oil responsibly is crucial for the environment. We strictly adhere to eco-friendly practices, disposing of old oil safely and recycling whenever possible, ensuring sustainability alongside quality service.
