Monitoring Oil Life Systems (OLS)
Most modern vehicles equipped with Dexos 1 specifications feature an Oil Life Monitoring (OLS) system. This isn’t just a timer; it’s a sophisticated algorithm that considers:
- Engine revolutions
- Engine temperature
- Vehicle speed
- Trip length
- And more…
The OLS accurately calculates the remaining life of your oil. Trust it! When the system indicates it’s time for an oil change (usually around 15-20% life remaining), schedule it promptly. Don’t push it to 0% if you can avoid it, especially under severe driving conditions.
Understanding Driving Conditions
Your driving style and environment significantly impact oil life. While the OLS accounts for many factors, it’s good to be aware:
- Short Trips: Frequent short drives (under 10-15 minutes) prevent the engine from reaching optimal operating temperature, leading to moisture and fuel dilution in the oil. This is considered severe service.
- Stop-and-Go Traffic: Prolonged idling and constant acceleration/deceleration generate more heat and stress on the oil.
- Towing/Hauling: Heavy loads put extra strain on the engine, increasing oil temperatures and accelerating breakdown.
- Dusty Environments: Off-roading or driving on unpaved roads introduces more particulates, which the oil must contend with.
If your driving frequently falls into these “severe service” categories, consider slightly shorter oil change intervals than the OLS might suggest, or at least be extra vigilant about checking your oil level and condition.
Responsible Disposal
Used engine oil is a hazardous waste and must be disposed of properly. Never pour it down drains or onto the ground. Most auto parts stores, service stations, and municipal waste facilities offer free used oil recycling.
- Collect used oil in a clean, sealed container (the empty new oil bottles work perfectly).
- Locate your nearest recycling center.
- By recycling, you prevent environmental contamination and allow the oil to be re-refined into new lubricants or other products. This is part of being an “eco-friendly oil with dexos 1” user.
