Do I Really Need to Warm Up My Car on Cold Ohio Mornings?
Short answer: Not as much as you think — but a little warm-up time still helps.
At Ohio Auto & Truck Center in North Lewisburg, we get this question a lot when the frost hits:
“Do I really need to let my car idle in the morning during winter?”
Let’s break down the facts — especially for drivers and fleets navigating cold starts in Central Ohio.
The Myth: Long Warm-Ups Are Necessary
This myth started decades ago with older, carbureted engines. But today’s fuel-injected engines are built for all weather. Long idling (10–15 minutes) is usually unnecessary — and wastes fuel.
The Truth: 30–60 Seconds Is Plenty
Even with modern tech, your engine oil is cold and thick on winter mornings. Giving your vehicle a brief 30–60 second idle helps:
Circulate engine oil
Prepare components for smoother driving
Prevent wear-and-tear during cold starts
Then, drive gently for 5–10 minutes to bring your vehicle to full operating temperature.
What Happens If You Don’t Warm It Up?
Skipping the warm-up and revving a cold engine can lead to:
Increased engine wear
Poor fuel economy
Rough starts and idle
Higher long-term maintenance costs
Especially true for diesel trucks and heavy equipment.
Cold Start Tips for Ohio Winters
Start and idle for 30–60 seconds Drive gently during warm-up period Keep your battery charged and tested Use proper oil viscosity and anti-gel diesel additives Install a block heater for diesel or heavy-duty equipment
Remote Starter? Use It Smart
We get it — using a remote start while you sip coffee feels great. But long idles just burn fuel.
The smarter move? Remotely start your vehicle about 1–2 minutes before you leave. That’s all it takes to get things moving.
