Can you drain new oil and put it back in?
The same logic applies regardless of whether your car uses synthetic motor oil or conventional motor oil. In the end, putting new oil in your vehicle after you have drained your motor for a repair is the safe and smart way to go.
What happens if you change your oil wrong?
Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so. Contrary to what some believe, adding synthetic oil to regular oil won’t harm the engine, but there’s also no benefit in doing so.
How do I know when my oil is done draining?
Remove the drain pan from under the vehicle and give the car a test drive. Go around the block a couple of times. Let the oil settle down again for 5 to 10 minutes, then recheck the dipstick. If it’s still at “Full,” you’re good to go!
How much does it cost to drain and fill engine oil?
Typically, an oil and filter change using conventional oil will cost between $35 and $75, depending on your area. If your car requires synthetic oil, you should expect to pay anywhere from $65 to $125.
Is Thicker oil better for high mileage cars?
High-mileage motor oil doesn’t hurt and it could prevent leaks from starting. Some mechanics recommend switching to a thicker (higher viscosity) oil — such as 10W-30 full synthetic oil instead of 5W-20 full synthetic — or using oil additives to stop leaks.
What happens if I put 5w20 instead of 5w30?
No, it is not recommended to change the oil type for your engine because 5w30 has a higher viscosity than 5w20. 5w20 oil is fairly light oil and is generally designed to work with newer engines.
Is it bad to put oil back in after taking it out?
Nothing wrong with doing this at all. Just make sure that you keep the oil clean and put back in as much as you take out!
Is there anything wrong with reusing engine oil?
As @dodgethesteamroller stated, there is nothing wrong with reusing the engine oil. There are two caveats and one concern I’d like to mention with this. First, use a clean container to store the oil in while you are doing your engine work. Your normal engine drain pan will probably not give you the cleanliness you are looking for.
Can you use old oil in a new car?
While new oil is always preferable it is entirely possible to drain the old engine oil out and run it through some fine filters (even like one or two of those paper paint strainers or an old cotton t-shirt and then use it to fill to back to the proper level.
