Your Nissan may just idle high during the warm up of your engine. These cars are designed to do this based upon the fact the cars have an optimum running temperature. If they idle high when for the first 15 minuets it's to achieve that optimum running temp. If not then you may have a vacuum leak.
If you are looking at the engine they are on the left hand side (passenger side) the low and the high are right next to each other. The have blue caps on the low and high, the high sits up higher then the low and if you look closely at the cap they are marked with a capital Letter H for the high and a capital L for the low.
I currently own 2 Nissan and the mileage on both are high. My 96 Altima is 325,568 right now and it is still running great. The other one I have is a 94 Sentra and the mileage on that is over 400,000 and again it is still running great. I know that didn't directly answer your question, but it might give you an idea of what to expect from these autos.
Castrol Brand Oil. I've did a trial test between Valvoline and Castol. First I've used the Valvoline Oil and noticed a little engine noise and not enough "ummphh". When I've tried the Castrol oil, I've noticed how smooth and quick the car was and it felt like it was new! I have a Sentra with 147,000 miles and use High Mileage oil
