After changing the oil on your Chevy Silverado, you need to reset the oil life monitor so it starts counting fresh from 100%. GM’s system isn’t a simple mileage timer like Toyota’s. It’s an algorithm-based monitor that calculates remaining oil life based on engine RPM, operating temperature, idle time, driving conditions, and time since the last reset.
This means the system accounts for how you actually drive, not just how far you’ve driven. Here’s how to reset it on every recent Silverado generation.
T1 Silverado (2019+): Infotainment Method
Turn the ignition to ON without starting the engine (or start the engine; either works). On the infotainment touchscreen, navigate to Settings > Vehicle > Oil Life. Select “Reset” and confirm when prompted. The oil life display returns to 100%.
Alternatively, you can use the DIC (Driver Information Center) controls on the steering wheel. Press the scroll buttons to navigate to the Oil Life screen in the instrument cluster, then press and hold the checkmark button until the display resets to 100%. Both methods achieve the same result.
K2 Silverado (2014-2018): DIC Button Method
Turn the ignition to ON without starting the engine. Press the DIC menu button (located on the turn signal stalk or the steering wheel, depending on your trim level and options) to scroll through the instrument cluster displays until you reach the “OIL LIFE REMAINING” screen.
Press and hold the checkmark or SET/RESET button for approximately 5 seconds. The display flashes and resets to 100%. Turn the ignition off, then start the truck and verify the oil life now shows 100%.
Why GM’s Oil Life Monitor Is Algorithm-Based
Unlike Toyota’s mileage-based reminder that simply counts down from a fixed distance, GM’s Oil Life System (OLS) uses an algorithm that factors in engine speed (RPM), coolant temperature, intake air temperature, vehicle speed, idle time, and operating load. This means the oil life percentage reflects actual oil degradation rather than just distance traveled.
A Silverado that spends its life on highway road trips might show 50% oil life remaining at 8,000 miles, because consistent highway cruising is easy on oil. The same truck making short city trips in cold weather might hit 50% at just 4,000 miles, because cold starts, incomplete warmup cycles, and frequent idle time degrade oil much faster.
The algorithm is genuinely sophisticated, and you can trust its recommendations more than a generic 3,000-mile or 5,000-mile interval. If you’re looking for other ways to make your truck more fuel efficient, proper oil maintenance is a good start.
What Percentage Should You Change At?
GM recommends changing the oil when the monitor reaches 0%, but most mechanics suggest not pushing past 10% to 15% remaining. When the “CHANGE OIL SOON” message appears (typically around 5% to 10%), treat it as a firm deadline rather than a suggestion.
Running past 0% means the oil has exceeded its useful life according to GM’s algorithm, and every additional mile risks accelerated engine wear. If the message says “OIL CHANGE REQUIRED” (which appears after extended driving past 0%), the system is telling you the oil is significantly past its service life. Change it immediately and reset the monitor.
Dexos1 Oil Requirement
All 2011+ GM trucks, including the Silverado, require Dexos1-certified oil. This isn’t just a recommendation; it’s a warranty requirement. Dexos1 is GM’s proprietary oil specification that ensures the oil meets specific performance standards for protection, fuel efficiency, and emissions system compatibility.
Use Dexos1-approved full synthetic oil in the viscosity specified on your oil cap (typically 0W-20 for newer engines or 5W-30 for older ones). Using non-Dexos oil can affect warranty coverage.
Most major oil brands (Mobil 1, Valvoline, Pennzoil, Castrol) offer Dexos1-certified formulas. Look for the Dexos logo on the bottle.

Unlike electric vehicles, which have minimal maintenance needs (check out whether electric cars need oil changes at all), your Silverado requires regular oil changes to keep running properly.

It covers 50+ popular vehicles across all major makes, with step-by-step instructions you can copy or print for use right in the garage.
Frequently Asked Questions
What if I forgot to reset after an oil change?
You can reset at any time using the same procedure. The monitor starts fresh from 100% regardless of when the actual oil change occurred. The algorithm won’t accurately reflect your current oil condition until the next full monitoring cycle, but resetting late is better than not resetting at all.
Does the Silverado need Dexos oil?
Yes. All 2011+ GM vehicles require Dexos1 Gen 2 or Gen 3 certified oil. This is part of GM’s warranty terms. Look for the Dexos logo on the bottle when purchasing oil.
Why does my oil life drop fast in winter?
Cold starts, short trips, and extended idle time all accelerate oil degradation. The algorithm accounts for these conditions by reducing the remaining oil life more quickly. Winter driving in cold climates can cut oil change intervals nearly in half compared to highway-focused summer driving.
Can I compare my Silverado’s towing performance to other trucks?
Absolutely. If you’re towing a travel trailer and want to see how the Silverado stacks up against its main competitor, check out our Ford F-150 vs Chevy Silverado towing comparison. We also have a full ranking of every pickup truck by MPG if fuel efficiency matters to you.
