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.

I'm gonna have to disagree with them. There is no such thing as lifetime oil. Even gear oil should be replaced eventually. Not too often though. Every 5 years is more than enough for diffs and manual transmissions IMO.

When there's already a problem, it's too late to change the fluid. One exception: auto trans fluid + filter change can cure a transmission that's shifting harsh or flaring during shifts, because ATF actuates the clutches and brakes. But it's still better to do it before you have problems.
