- Extended Drain Intervals: Often allows for longer periods between oil changes, as per your vehicle’s Oil Life Monitoring system.
Choosing the Right Dexos Oil: A Perform Dexos Oil Guide
Selecting the correct Dexos oil is the first critical step to properly perform Dexos oil maintenance. There are two primary specifications: Dexos1™ Gen 2 (or Gen 3) and Dexos2™.
Dexos1™ is typically for gasoline engines, while Dexos2™ (or now DexosD™ for diesel engines) is for diesel engines, though some gasoline engines in specific markets may use Dexos2™.
Decoding Dexos Specifications
Always check your owner’s manual or the oil fill cap for the exact Dexos specification required for your vehicle. Using the wrong specification can lead to suboptimal performance and potential engine damage.
For most modern GM gasoline vehicles, Dexos1™ Gen 2 or Gen 3 is the standard. These oils are typically synthetic or synthetic blend, offering superior performance over conventional oils.
Viscosity and Climate Considerations
Beyond the Dexos specification, pay attention to the oil’s viscosity (e.g., 0W-20, 5W-30). Your owner’s manual will specify the recommended viscosity for your engine.
While modern multi-grade oils are designed for a wide range of temperatures, extreme climates might influence your choice. Always stick to the manufacturer’s recommendation first.
How to Perform Dexos Oil Change: A Step-by-Step for DIYers
Learning how to perform Dexos oil changes yourself can save money and give you a deeper understanding of your vehicle. This guide will walk you through the process safely and effectively.
Safety First: Always work on a level surface with the engine cool or only slightly warm. Use jack stands for stability, never rely solely on a jack. Wear appropriate safety gear, including gloves and eye protection.
Gather Your Tools and Supplies
Having everything ready beforehand makes the job smoother. Here’s what you’ll need:
- New Dexos-approved engine oil (check your manual for capacity).
- New oil filter (ACDelco or equivalent OEM quality recommended).
- Oil filter wrench (cap-style or strap-style).
- Socket wrench and appropriate socket for the drain plug.
- Drain pan (large enough for your oil capacity).
- Funnel.
- Clean rags or shop towels.
- Jack and jack stands.
- Torque wrench (for drain plug and potentially oil filter housing).
The Oil Change Process
- Prepare Your Vehicle: Drive your vehicle for a few minutes to warm the oil, but not make it scalding hot. Park on a level surface, engage the parking brake, and block the wheels.
- Lift and Secure: Use your jack to lift the front of the vehicle and place jack stands securely under the frame. Never work under a vehicle supported only by a jack.
- Locate Drain Plug and Pan: Place your drain pan directly under the oil pan drain plug.
- Drain the Oil: Using the correct socket, carefully loosen and remove the drain plug. Be prepared for oil to flow out quickly. Allow all the old oil to drain completely, which can take 10-15 minutes.
- Replace Drain Plug: Once drained, clean the drain plug and its washer (replace the washer if it’s crushed or damaged). Reinstall the drain plug and tighten it to the manufacturer’s specified torque using a torque wrench. Overtightening can strip threads, while undertightening causes leaks.
- Remove Old Oil Filter: Position your drain pan under the oil filter. Use an oil filter wrench to loosen and remove the old filter. Some residual oil will spill, so be ready with rags.
- Prepare New Oil Filter: Apply a thin film of new engine oil to the rubber gasket of the new oil filter. This ensures a good seal and prevents the gasket from tearing.
- Install New Oil Filter: Hand-tighten the new filter until the gasket makes contact with the engine block, then turn it an additional 3/4 to 1 full turn. Do not overtighten. Some manufacturers specify a torque setting; consult your manual.
- Add New Oil: Lower the vehicle carefully. Locate the oil fill cap on your engine. Using a funnel, slowly add the recommended amount of new Dexos oil. Start with slightly less than the full capacity, then check the dipstick.
- Check Oil Level: After adding oil, wait a few minutes for the oil to settle. Pull out the dipstick, wipe it clean, reinsert it fully, then pull it out again to check the level. Add small amounts of oil until the level is within the “full” marks.
- Start Engine and Check for Leaks: Start the engine and let it run for a minute or two. Check for any leaks around the drain plug or oil filter. Turn off the engine, wait a few minutes, and recheck the oil level. Top off if necessary.
- Reset Oil Life Monitor: Consult your owner’s manual for instructions on how to reset your vehicle’s Oil Life Monitoring system. This is crucial for accurate service reminders.
- Dispose of Old Oil: Properly dispose of your used oil at a local auto parts store, service station, or recycling center. Never pour it down a drain or on the ground.
Advanced Perform Dexos Oil Tips and Best Practices
Going beyond the basic oil change can further enhance your engine’s life and performance. These perform Dexos oil tips are designed for meticulous DIYers and enthusiasts.
Monitor Your Oil Life System
Your vehicle’s Oil Life Monitoring (OLM) system is an advanced tool. It considers factors like engine temperature, RPMs, and driving conditions to determine when an oil change is truly needed.
Don’t just rely on mileage; trust your OLM, but also perform visual checks regularly. Off-roaders, those who tow, or drive in extreme conditions might see their OLM recommend changes more frequently.
Regular Visual Inspections
Between changes, periodically check your oil level and inspect its appearance. Dark brown or black oil is normal, but milky or frothy oil could indicate coolant contamination, a sign of a serious issue.
Look for metal shavings or unusual particles on the dipstick, which could point to internal engine wear. Early detection can save you from costly repairs.
Consider an Engine Flush (with caution)
While generally not recommended for well-maintained engines using quality synthetic oils, a gentle engine flush might be considered for vehicles with a history of neglected oil changes or sludge buildup.
Consult a professional before using harsh flush products, as they can sometimes dislodge large deposits that clog oil passages. Stick to high-quality Dexos oil for prevention.
Troubleshooting Common Problems with Perform Dexos Oil
Even with careful maintenance, issues can arise. Knowing how to identify and address common problems with perform Dexos oil can prevent bigger headaches.
Oil Leaks After a Change
The most common cause of leaks after an oil change is an improperly tightened drain plug or oil filter. Double-check both for tightness.
Ensure the old oil filter gasket wasn’t left stuck to the engine block, creating a double-gasket situation. If the leak persists, it might be a damaged oil pan gasket or a more serious engine seal issue, requiring professional attention.
Incorrect Oil Level Readings
An inaccurate dipstick reading can be frustrating. Ensure your vehicle is on a level surface and the engine has been off for at least 5-10 minutes (longer for some engines) to allow oil to drain back into the pan.
Overfilling is as bad as underfilling; it can cause aeration of the oil and damage seals. If you’ve overfilled, you’ll need to drain some oil out.
Oil Pressure Warning Light
If your oil pressure warning light illuminates after an oil change, stop driving immediately. Check your oil level. If the level is correct, there might be a problem with the oil pressure sensor, the oil pump, or a serious internal issue.
Do not continue driving with low oil pressure, as it can cause catastrophic engine damage. Call for a tow and have it professionally inspected.
Sustainable Perform Dexos Oil Practices: Eco-Friendly Choices
As responsible vehicle owners, adopting sustainable perform Dexos oil practices is crucial. It benefits the environment and can even save you money in the long run.
Proper Disposal of Used Oil and Filters
Never dispose of used engine oil or filters in the trash or down a drain. Used oil is a hazardous waste that can contaminate water sources.
Most auto parts stores, quick lube shops, and municipal recycling centers accept used oil and filters for free. Store used oil in its original container or a clean, sealed jug until you can take it for recycling.
Choosing Eco-Friendly Perform Dexos Oil
Many Dexos-approved oils are full synthetics, which inherently offer environmental benefits due to their longer drain intervals and better performance.
Some brands also offer “green” or eco-friendly perform Dexos oil options, often derived from natural gas or with enhanced biodegradable properties. Look for these if environmental impact is a top concern for you.
Extending Oil Life Responsibly
