Question RPM Question
My other car is a '99 Nissan Maxima with 141,000 miles. I have noticed that to maintain about 80 mph the car revs at about 3.3k rpm whereas when the car was newer (< 100k miles), it rev'ed at 3k rpm at 80 mph. As part of the scheduled maintenance I got new spark plugs recently. Does anyone have an idea if this is normal? If it is not, why is it happening?

Also, does the brand of fuel make a difference (Exxon/Sunoco/Shell vs US Gas)? I don't think it should. What is your opinion?
