Miles or time?

Cypress

As I reviewed the 370Z Owners manual and subsequently the Service and Maintenance manual, a question popped up. Well actually many but I wanted to hear from the experts here on their opinion.

Based on my driving habits, I usually rack up only 7-8K miles per year. According to the manual, they want service at 3750 miles or 3 months and so on. I only log about 600 - 700 miles a month or 1800 - 2100 miles every 3 months.

So there is the question. Do I do the recommended service by miles or months.

Oh, for those of you that will want more detail. Most of my driving is in Houston Texas where it is Africa hot and humid (I think today was 98 degrees with a billion percent humidity). My drive to work is about 10 miles of suburban driving. Only have about a 1 mile stretch there I get into a little stop light traffic. So I consider that fairly tame driving. - I know why did I get this car, I could have gotten a Kia van!!
