What are some of the best cars for touge racing?

I’m confident in changing my own oil, but just want to double-check—what type of oil should I use for my 2020 Jeep Grand Cherokee V6?

I drove my friends around all last night. It was so much fun, but I think I blew my car’s speakers out. It’s my parents’ car, so I’m a bit freaked out. How can I fix blown out car speakers?

I had to take my cat to the vet the other week. She wasn't feeling well (plus she hates car rides) and she ended up peeing on the seat. I love her and don't blame her at all, of course—but it doesn't smell very good. My cat is okay now—but how do I get cat pee out of a car seat?
