My Nissan NV1500 have 42000 miles.

Hello, first - do you have your owners manual and maintenance guide? That's the best place to look for this information that you can thoroughly learn more about. For us to weigh in here, we'd have to know if you drive "severe duty" miles or "normal duty". Since you're in LA, I'll default to "severe", as that's most likely. In this case, for 40,000 miles, the maintenance guide says: -Replace engine oil and filter -Replace brake fluid -Perform a multi-point vehicle inspection, including brake inspection -Lubricate steering stopper cap of your front knuckles At 45,000 miles, the cabin air filter should be replaced and tires rotated. Hope this helps.
