I have both a 1998 Altima and a 2005 Murano. I am using synthetic oil.
The dealer is asking that the oil be changed every 6000 klm, or every
3 months. These cars are not used every day.

As for the Murano, it is under warranty with a service contract.
Therefore I will follow what they want.

If for example, I only use a car for 3500 klm, but the 3 months are
up, is it safe to go to about 4 or 5 months between changes???

I realize that if a car is not used enough to heat the oil up to a
high enough temperature, it can accumulate moisture in it which is not
very good. I also realize that dirt and fine debris can accumulate and
the filter is not perfect.

I would be interested in some experienced opinions.

For example, if it takes me about 4 to 6 months to use the car 6000
klm, if this would be acceptable?  Or, should I change the oil every 3
months or 6000 klm; whatever comes first?
