Are You Making These Common Oil Change Service Mistakes?
Imagine you’re cruising down Highway 68 on a crisp Alabama morning. Your truck is running smooth, the coffee is hot, and you’re feeling pretty good because you just finished a DIY oil change over the weekend. You saved a few bucks, right? But then, you notice a faint smell of burning oil, or worse, a small puddle forming under your vehicle when you stop at the local hardware store.
At Mike’s Alignment & Tire Services Inc, we’ve spent over 35 years under the hoods of cars in Crossville. We’ve seen it all: from the minor drips to the “I-need-a-whole-new-engine” disasters. While an oil change service seems like the simplest maintenance task on your list, it is actually the most common place where small errors turn into massive repair bills.
Are you making these common mistakes? Let’s break down the pitfalls of the routine oil change and how you can keep your engine running like a top for another 200,000 miles.
1. The Cold Drain Dilemma
One of the most frequent mistakes happens before the wrench even touches the drain plug. Many folks try to change their oil when the engine is stone-cold. Think of motor oil like syrup: when it’s cold, it’s thick and sluggish. If you drain your oil when the car hasn’t run in hours, a good portion of the old, dirty sludge stays stuck to the internal components.
To get a truly clean oil change service, you want the oil to be warm (not boiling hot!). Letting your engine run for about 5 to 10 minutes allows the oil to thin out and suspend the tiny contaminants so they flow right out into the pan. If you drain it cold, you’re basically leaving yesterday’s dirt in today’s fresh oil.
2. The “Double Gasket” Disaster
This is the silent engine killer. When you unscrew your old oil filter, there is a rubber O-ring (the gasket) that is supposed to come off with it. However, sometimes that rubber ring gets stuck to the engine block.
If you don’t notice it and you screw the new filter on top of the old gasket, you’ve created a “double gasket.”
As soon as you start the engine and the oil pressure builds up, the seal will fail. It won’t just drip; it will spray oil out like a garden hose. We’ve seen engines seize in minutes because the driver didn’t realize they were losing all their oil on the road. Always, always wipe the mounting surface and make sure the old gasket is gone before the new filter goes on.
3. Choosing the Wrong Viscosity
“Oil is oil, right?” Not exactly. Your modern engine is a precision machine with tiny passages that require a very specific thickness of oil to lubricate correctly. If your manual calls for 0W-20 and you throw in 10W-30 because it was on sale, you’re asking for trouble.
Using the wrong viscosity can lead to:
- Reduced fuel economy.
- Increased wear during cold starts.
- Engine overheating in the Alabama summer heat.
- The check engine light popping on due to variable valve timing issues.
At Mike’s, we’ve learned through decades of auto repair service in Crossville that following the manufacturer’s specs is non-negotiable. If you’re unsure what your car needs, just ask!
4. The “Hulk” Grip: Overtightening the Drain Plug
We get it: you don’t want your oil leaking out. But cranking down on that drain plug with all your might is a recipe for a stripped oil pan. Most oil pans are made of aluminum or thin steel. If you strip those threads, you’re looking at an expensive oil pan replacement rather than a simple $15 plug fix.
The goal is “snug,” not “welded shut.” Usually, a quarter-turn past finger-tight is plenty, or better yet, use a torque wrench to meet the specific foot-pounds required for your vehicle. And don’t forget to replace the crush washer! That little 50-cent washer is what actually does the sealing, not the tightness of the bolt.
5. Forgetting the Filter (The “I’ll Do It Next Time” Trap)
Some people think they can get away with changing the oil but leaving the old filter in place to save a few dollars. This is like taking a shower and putting your dirty socks back on.
The filter’s job is to trap metal shavings, carbon, and dirt. Once it’s full, a bypass valve opens, and your engine starts circulating unfiltered, dirty oil. A fresh oil change service should always include a premium-quality filter. It’s the cheapest insurance policy you can buy for your car.
6. Not Checking the Level After the Change
You poured in five quarts, so you’re good, right? Maybe not. Some engines hold 5.2 quarts, some hold 8. Every car is different.
After you finish the change, you need to run the engine for a minute to let the oil fill the new filter, then shut it off, wait a few minutes for the oil to settle, and check the dipstick. Being a quart low: or a quart over: can both cause internal damage. Overfilling can lead to “frothing,” where the oil gets bubbles in it and can’t lubricate the parts correctly.
7. The Mystery of the Missing Fill Cap
It sounds silly, but it happens to the best of us. You get distracted by a phone call or a neighbor stopping by, and you forget to put the oil fill cap back on. You drive off, and suddenly smoke is billowing from under the hood as oil splashes out onto the hot exhaust manifold. Always do a “final sweep” of the engine bay before you close the hood.
