If you read any manual on changing your oil, it's going to tell you to let that thing drip for 15 to 30 minutes to clear out as much of the old oil as possible. Meanwhile, your average oil change place is advertising that they will have you in and out of there in 15 minutes from start to finish. Which means there's no way they're letting it drip the minimum of 15 minutes.

The soil change was so overdue. There is a difference between the service interval and abuse interval of oil. I definitely got into the abuse range on this occasion. I just didn't have the money for the oil and the filter.

And while you're taking care of your own oil change. Make sure to check your brake fluid engine coolant and washer fluid and top them off as necessary.

At oil change shops I’m pretty sure they use compressed air to blow all the oil and residue out

    I can confirm for you that they do not do this.

    Source: I worked at one for many years. We let it drain till it was either a slow drip or stopped entirely depending on how busy we were.

    TIL. Thanks for the information! Once I saw a guy use a special vacuum set up but I don’t think it’s typical. I almost always change my own oil anyways

    TIL as well. I've never seen or heard of a vacuum setup for oil changes. Other fluids? Absolutely, but not oil. To be fair, I've also been out of the industry for about a decade now so some shops may very well be introducing it, just none that I've personally seen yet. Neat either way!

    It was the cleanest oil change I’ve ever seen. I can’t even remember where he attached the vacuum to, but it had a tube with threading that fit an oil jug and then attached to a shopvac down the line, and it just sucked the oil out into the old container and then he capped the container and that was that. I was gobsmacked
