If you only drive a few times a week, for at least 30 miles per trip, then
you could wait for 3000 miles to change the oil without regard to any time
limit. But if you drive only a few miles for each trip (and the engine
usually does not get fully warmed up), then you need to stick to the time
limit of 3 months.

If you use a full synthetic oil (not including the Castrol scam oil), you
can go 7500 miles or 6-9 months between changes. If you do the math, you
will find that using synthetic oil with a longer change interval is about
the same cost as conventional oil.
