Hello everyone, newbie here. I have been scouring the internet for days.....does anyone have a picture/diagram of where the oil plug is on the supercharger for a 2020 Saleen mustang? Saleen performance has the worst customer service ever and won't answer my emails/chat requests OR answer their phones. More info: I'm a female that knows very little about engines; I just purchased the car and want to change the oil in the supercharger so I don't have to pay a mechanic to do it as previous owner said he never did it and the car is at 53k miles. I've looked and theres so much stuff crammed in under the hood (and I don't know what I'm looking for ) that I can't even begin to figure out where the plug is.

No expert on newer mustangs, but this popped up when i Googled your question. Can you find the brass plug called out in bullet point #1?

For the 2020 Saleen Mustang supercharger oil plug, here are some key points:
  • The oil in the supercharger is refilled via a brass plug located on the driver's side, underneath the water crossover.

    1
  • The supercharger takes a full pint of oil, and the oil that comes with it is recommended to last for 50,000 miles.

    2
  • If you need to change the oil, it is suggested to do so every 5,000 miles.

    1
  • Saleen recommends checking the oil level in the SC reservoir every 40,000 miles or 4 years, whichever comes first.

I think I found it; I found a picture of a supercharger from a PDF for Saleen from 2008-2009; its behind a pulley and the only thing that looks kinda brass colored. I'm going to unscrew it and see what happens; thank you!
