Red neck oil change 

Changing the oil of your car in the parking lot of a auto store so you can buy and dump the oil off without having to drive to and from the store.

Me and my friend are going to do a red neck oil change, want to come?

helping a friend get an oil change 

A rather working-class term for jacking off.

My boss asked me why I was fifteen minutes late for work; and I told him I was helping a friend get an oil change. Thankfully, he believed me.

2 fingered mexican oil change 

When you stick two fingers up another persons anus, but you do it every couple of minuets. Since a regular mexican-oil change keeps adding oil, you keep adding your finger.

She was getting clogged up back there, so I gave her the 2 fingered mexican oil change, and now she "runs" clean.

Detroit Oil Change 

The act of shitting in a girls mouth, then having her spit it back into your mouth.

"Man, last night, I gave Amber a Detroit Oil Change for the first time and that sick fuck loved every second of it."

Tijuana Oil Change 

On a driveway (often covered with newspaper for easy clean-up), one person lets diarrhea drain from them while another person pours fresh diarrhea into his/her mouth, possibly through a funnel. A cooperative act.

Harvey went for a jog around the block to warm up before Brad helped him with his Tijuana Oil Change.

Instant Oil Change

from the missionary position, the man dips his dick into the vag of a girl on her period in the same manner one would use a dipstick to check for oil.
then, while the girl is suspended on chairs, the man gets underneath her, opens her vag, and then catches and swallows the menstrual blood as it leaks out, like an oil pan.

Ted: "So, I was goin' down on my girlfriend last night, but she was on her period, so I performed an instant oil change on her."

Ned: "DUDE! That is sick! Nice!!!"

Ted: "I know right?! Which reminds me, I need to go to Jiffy Lube."

Ned: "Lol, Jiffy Lube."
