Hey guys, I posted last night that I got my first Audi, but I wanted to get some guidance to make sure I take care of it properly. I know a lot of these questions might seem silly, but I’ve waited over 20 years for an Audi, so this car means a lot to me. Please be gentle; I know I sound dumb. I just really wanna do it right. I only slept for one hour because I spent the night reading the manual lol. I know it says high octane gas, 91 or above. Is Shell Nitro the best? What do you all use? The manual suggests Castrol Edge Professional. Should I stick with that or is there something better? My research into windshield wiper fluids led me to Nextzett Concentrate. Is that good or should I choose something else? Since I live in SoCal, we get cold weather but rarely freezing. Do I still need antifreeze? Are antifreeze and cool the same thing? The names suggest one prevents freezing and one cools things down, but I’m not sure. It’s just my 8-year-old daughter and me, and everything I know about cars is self-taught. I want to do better by her than what I had, so I’m trying to learn all I can to keep our car beautiful and pass the knowledge on to her too. Any advice or suggestions are welcome. Please don’t be too harsh on my ignorance here. 
I’ve added some photos of her as a thank-you for your help.

Congrats on your first Audi! For gas, Shell Nitro is a great choice, but any reputable brand with the right octane will do. Just make sure to avoid cheap gas stations.

Thanks! I’ll stick with Shell then. Appreciate it!
Castrol Edge Professional is solid, but you could also look into Mobil 1 or Liqui Moly. Just make sure it meets the specs in your manual.

Got it! I’ll check those out too. Thanks for the tip!
Nextzett Concentrate is good stuff! It’ll keep your windshield clean and clear. Just mix it according to the instructions for best results.
In SoCal, you don’t need antifreeze in the winter, but it’s good to have coolant in the system to keep everything running smoothly. Antifreeze and coolant are similar, but antifreeze prevents freezing while coolant helps regulate engine temperature.

Thanks for clarifying that! I really appreciate it.
You’re doing great! It’s awesome that you’re learning for your daughter. Just keep up with regular maintenance, and your Audi will treat you well. Enjoy the ride!
