Summer Car Safety Tips: What to Check Before Your Road Trip
April 23, 2026
If you have had your oil recently changed you probably notice the service sticker placed on your windshield. It is the mileage for your next oil change. But many newer vehicles also display an oil life percentage on the dashboard.
This often leads to a common question from customers:
“Should I follow the oil life monitor or the mileage sticker?”
At our shop, we recommend following the mileage listed on the windshield sticker for the best preventive maintenance and long-term engine protection.
Understanding the Difference
The Windshield Sticker
The sticker in your windshield. Provides a recommended mileage interval for your next oil change. This is a simple and reliable way to stay on schedule with maintenance.
The mileage on the sticker is the mileage at which we recommend changing the oil.
The Oil Life Monitor
Many modern vehicles use an oil life monitoring system. That calculates remaining oil life based on:
ü Driving habits
ü Engine temperature
ü Idle time
ü Towing or heavy loads
ü Short trips
ü Overall engine operating conditions
Because of this. Two vehicles with the same mileage may show completely different oil life percentages.
What Oil Percentage Is Common for an Oil Change?
Most manufacturers and service professionals consider these guidelines standard:
ü 20% Oil Life – Time to start planning your next oil change
ü 15% Oil Life – Common recommendation for oil service
ü 5% Oil Life – Oil change is overdue soon
ü 0% Oil Life – Change oil immediately
While the oil life monitor is helpful, many drivers wait too long to schedule service, when relying only on the dashboard percentage. Also waiting more than 3,000 miles without checking your oil level can have your vehicle running.
Why We Recommend Following the Sticker
We recommend the mileage on our windshield sticker. The sticker is designed to protect your engine through consistent preventive maintenance intervals. Waiting until the oil life monitor reaches very low percentages. You may increase wear on your engine, especially under:
ü Stop-and-go driving
ü Extreme temperatures
ü Short-trip driving
ü Towing or hauling
ü Turbocharged engine conditions
Regular oil changes help maintain:
ü Proper oil level
ü Proper lubrication
ü Engine performance
ü Fuel efficiency
ü Long-term engine life
Recommendation
For the best engine protection, we recommend:
Change your oil at the mileage listed on the windshield sticker. Or before the oil life monitor drops below 15%, whichever comes first.
Following this guideline helps you avoid overdue maintenance. It keeps your vehicle running at its best.
