FTC advice ↗How a change works
The drain plug comes out and the used oil runs into a pan. It goes to recycling, not the gutter.
The old filter comes off with the oil it's holding. EPA says used filters can be drained and recycled too.
The grade and type your owner's manual lists, in the amount it lists.
The level should land between the marks. Ask them to reset the oil life monitor and note your next one.

The history
Motor oil started as a doctor's lubricant for steam engines. The schedule moved from a flat number to the car counting for you. Swipe through.
Dr. John Ellis founds the Continuous Oil Refining Company in Binghamton, New York, to make a lubricant for steam engines. It's later named Valvoline.
In the mid 1970s, synthetic motor oils are formulated and used in cars for the first time.
Polyethylene bottles start replacing glass and metal oil containers in the early 1980s.
By the mid 1980s, recommended viscosities drop to 5W-30, mostly to improve fuel economy.
GM is granted a patent for an automatic oil change indicator that tracks engine revolutions and temperature.
GM adds its oil life system to all new Chevrolet Silverado and GMC Sierra full size pickups.
CalRecycle launches a campaign telling Californians to check the oil change interval in their owner's manual.
SAE introduces an SAE 16 viscosity rating for even thinner oils.

Good to know
Check your number: your owner's manual or your car's oil life monitor sets it. CalRecycle says the old 3,000 mile standard is out of date for most cars, and many cars can go 5,000, 7,500, 10,000 or even 15,000 miles between changes.
Use the type and grade your owner's manual lists. Fueleconomy.gov says using the manufacturer's recommended grade can improve gas mileage by 1% to 2%.
Not much on its own. Heat and soot darken oil as it does its job. Go by your owner's manual or oil life monitor.
Follow your owner's manual. A typical one says to park on level ground, warm the engine, shut it off and wait a few minutes, then pull the dipstick, wipe it, push it back in and read the level between the marks. Overfilling can harm the engine too. Can't find a dipstick? Your manual shows how your car reports the level.
The FTC says it's illegal for a dealer to deny warranty coverage just because routine maintenance or repairs were done by someone else. Keep your receipts and service records.
Ask the shop how they recycle it. If you change it yourself, take the oil and the filter to a CalRecycle certified collection center. EPA says re-refined oil must meet the same standards as new oil.
The Department of Energy says all-electric cars have fewer fluids, like engine oil, that need regular maintenance. It says hybrids and plug-in hybrids need the same general maintenance as conventional cars.
Each shop sets its own price based on your car, the oil it takes and the filter. Shops quote you through Lokuli, so you can compare before you book.
