Many car owners wonder, what's synthetic oil and why is it better? At its core, synthetic oil is chemically engineered from base oil components, unlike conventional oils which are refined from crude oil. This precise engineering allows for greater control over the oil's properties, such as viscosity, thermal stability, and resistance to degradation. Dexos is a specific type of full synthetic oil, a global engine oil specification developed by General Motors, designed to be the best motor oil for their vehicles, though many non-GM cars can also benefit. It provides critical benefits like reduced friction, better sludge prevention, and improved fuel economy.
Imagine this scenario: your car’s engine working tirelessly, day in and day out. What's in synthetic oil that makes it so special? It’s the meticulously crafted molecular structure. Unlike conventional oil, which can have impurities and inconsistent molecular sizes, full synthetic oils are built with uniform molecules. This uniformity means less friction, better lubrication even at extreme temperatures, and a superior ability to withstand the heat and pressure inside your engine. This translates to less wear and tear over time, which is crucial for maintaining your vehicle's value and reliability.
When was synthetic oil invented? While the concept of synthetic lubricants dates back to the early 20th century, widespread adoption and the development of advanced formulations like Dexos full synthetic are much more recent, gaining significant traction from the late 20th century onwards. The evolution reflects a continuous drive for better engine protection and efficiency, addressing the demands of increasingly sophisticated engine designs.
It’s the little things that truly count for your engine's longevity.
Prerequisites: What You Need Before You Start
Before diving into the oil change, gather everything necessary. You'll need the correct type and amount of dexos full synthetic motor oil – check your owner's manual for the precise specification (e.g., 0W-20, 5W-30) and volume. A new oil filter compatible with your vehicle is essential, along with a new drain plug washer or gasket. You’ll also require basic tools: a socket wrench for the drain plug and oil filter, a drain pan large enough to hold all the old oil, a funnel, rags or paper towels, and potentially a car jack and jack stands for safe access underneath the vehicle. Safety glasses and gloves are highly recommended to protect yourself.
Your 5-Step Guide to Changing to Dexos Full Synthetic Oil
Changing your oil to dexos full synthetic motor oil is a straightforward process that pays dividends. Here’s a step-by-step breakdown to guide you through it. This narrative approach ensures you’re not just following instructions but understanding the purpose behind each action, making it a more satisfying experience for any DIYer.
Step 1: Warm Up the Engine
Start your engine and let it run for about 5-10 minutes. The goal is to warm the oil just enough so it flows more easily, carrying away more contaminants. Don't let it get scorching hot, though, as hot oil can cause severe burns. A slightly warm engine is key to a more efficient drain.
Step 2: Safely Raise and Secure Your Vehicle
If necessary, use a car jack to lift the front of your vehicle and place sturdy jack stands securely under the designated points. Never work under a vehicle supported only by a jack. Ensure the vehicle is stable and won't roll. This provides comfortable and safe access to the oil drain plug and filter.
This is the point where you must prioritize safety above all else.
Step 3: Drain the Old Oil
Position your drain pan beneath the oil drain plug, usually located at the bottom of the oil pan. Carefully loosen the plug with your socket wrench and then unscrew it by hand. Be prepared for the oil to flow out quickly. Let it drain completely for at least 10-15 minutes. Once drained, clean the plug and replace the old washer with a new one, then reinstall and tighten the plug snugly. Don't overtighten.
Step 4: Replace the Oil Filter
Locate the oil filter. You might need an oil filter wrench to remove it. Again, have the drain pan ready, as some oil will spill out. Before installing the new filter, apply a thin film of new oil to the rubber gasket on the new filter. This helps create a better seal and makes removal easier next time. Screw the new filter on by hand until it's snug, then tighten it an additional 1/2 to 3/4 turn, following the instructions on the filter itself.
Lubricate the new oil filter's rubber gasket with a bit of new oil before installation; this ensures a good seal and prevents it from sticking, making your next oil change significantly easier.
Step 5: Add New Dexos Full Synthetic Oil
Lower your vehicle if it was raised. Open the hood and locate the oil fill cap on top of the engine. Using your funnel, pour in the correct amount of dexos full synthetic motor oil specified in your owner's manual. Start with slightly less than the full amount, and you can top it off later.
This is where your engine truly gets its new lease on life.
Verification and Troubleshooting: Ensuring a Smooth Operation
After completing the oil change, a few crucial checks ensure everything is working as it should and prevent potential issues down the road. This verification stage is critical for the success of your DIY maintenance and the long-term health of your engine.
Step 6: Check the Oil Level and Run the Engine
Once the new oil is in, replace the fill cap. Start the engine and let it run for a minute or two. Watch the oil pressure light on your dashboard; it should turn off within seconds. Then, shut off the engine and wait a few minutes for the oil to settle back into the pan. Pull out the dipstick, wipe it clean, reinsert it fully, and pull it out again to check the oil level. It should be between the 'min' and 'max' marks. Add more oil incrementally if needed, rechecking until the level is correct.
Your engine, your story – make it a smooth one.
Common Issues and How to Solve Them
Oil Leak at the Drain Plug: If you notice a leak after starting the engine, the drain plug might not be tight enough, or the new washer wasn't seated correctly. Safely re-tighten the plug slightly. If it persists, you may need to drain the oil again, inspect the plug and pan threads, and install a new washer.
Oil Leak at the Filter: A leak from the oil filter usually means it wasn't tightened enough or the old gasket wasn't fully removed. Ensure the filter is properly seated and tightened, and that no part of the old gasket is stuck to the engine block. The trickiest part is often knowing which oil is thicker 10w 30 or 10w 40, or 10w 30 or 5w 30, but for dexos full synthetic, always stick to the weight recommended in your manual, as it's engineered for specific flow characteristics.
Low Oil Pressure Light Stays On: This is a serious warning. It could indicate insufficient oil level, a faulty oil filter, or an issue with the oil pump. Immediately shut off the engine and recheck the oil level. If the level is correct, do not drive the vehicle and seek professional diagnosis.
Engine Noises: New synthetic oil can sometimes reveal minor existing noises as it lubricates more efficiently. However, new, loud knocks or taps could signal an issue. Always use the exact viscosity recommended by your manufacturer; for instance, if your manual specifies 5W-30, don't use a 10W-30 as it will be thicker when cold.
The true value of high-quality synthetic oil lies not just in its immediate performance, but in the years of reliable service it helps ensure.
Keep a small notebook in your glove box to record the date and mileage of your oil changes; this simple habit is invaluable for maintenance tracking and can even increase your vehicle's resale value.
Properly changing to dexos full synthetic motor oil ensures your engine benefits from the most advanced protection available, contributing directly to its longevity and smooth operation. It's a straightforward process that puts you in control of your vehicle's most vital fluid.
