Too many miles per day?

I have a 2000 Honda Civic Ex in pretty good condition it has 126,000 miles on it currently but recently this summer i have been driving it allot, like 150-165 miles per day during the week. I plan on using it like this for about another month and a half, yet i plan on getting oil changes and getting it serviced accordingly. During the rest of the year i plan on bringing it back down to average use driving it about 3 miles to school and 20 round trip to work every other day. Am i using my car too much? Are there any other extra pro cautions i should take to make sure this recent use doesn't ruin my car?
