You want to get a oil change every 4000 miles. how many changes do you in year driving 1000 miles month?

To determine the number of oil changes needed in a year driving 1000 miles per month, we need to calculate the total miles driven in a year and divide it by the oil change interval of 4000 miles.

First, we need to find the total number of miles driven in a year:

Miles driven per year = Miles driven per month × Number of months in a year

= 1000 miles/month × 12 months/year

= 12,000 miles/year

Now, we can calculate the number of oil changes required:

Number of oil changes = Total miles driven / Oil change interval

= 12,000 miles/year / 4000 miles/change

= 3 oil changes/year

Therefore, driving 1000 miles per month will require 3 oil changes in a year.
