What is the oil type for the 2018 Nissan Pathfinder?

I recently got into a car accident where my airbags were deployed. I filed a claim but I’m still waiting to hear back from my car insurance to find out if it was totaled. Is your car totaled when airbags deploy?

I’m taking over the payments for my brother’s 2021 Mercedes GLA 250 because he’s moving abroad and won't need a car. Since I wasn’t with him when he bought it, I didn’t get the full rundown of the warranty policy. What does it include?

I have two cars. One I use for commuting and errands; the other I use far less. The annual mileage for the latter is about 3,000 miles and it's the most expensive car on my policy. It is financed and I'm wondering how I can get cheaper insurance on it since I don't drive it very often.
