I was wondering if I HAD to change my spark plugs
I have 85k on my maxima.
does it give you better milage or something?

 

Well put it this way, you don't HAVE to change your oil either. So....

 

I don't change my oil.

 

....every 3000 miles

 

so im guessing i can use it till my car blows up?

 

.....or even every 15,000 miles....
















as the new Oil spreadsheet will illustrate....

 

really?

 

It's your car....Nissan recommends 60k with NGK plats.....do what you want.



Jeff and I won't lose sleep over it.

 

I might need some aspirin though http://forums.maxima.org/showthread.php?threadid=92689

 

yes

 

 

 

I'm surprised any member here listens to anything that comes out of the mouths of Nissan's "Customer Care" department.

 

 

Every 3000 is the way to go.....

 

HAVE replace plugs? Not at all. BUT you should at least pull them and check gapping color (make sure not fouled) and make a general inspection. If they look good-not need to replace. But if you are unsure-a relatively inexpensive way to help maintain your cars performance.

 

Your vehicle's overall power, gas mileage, and efficiency boils down to the spark. If the spark is not good enough, you're wasting fuel, thus driving down your fuel economy and power that is being made. Change them.. they're inexpensive and not difficult to replace.
