Differential Oil
 

How often should it be replaced? for future reference.
Because I just did it the other day (simple enough). And as far as I know, it has never been changed, th ecar has around 155,800 or so-ish
Mobil1 75w90

30,000 miles is what I've always been told.

thanks:038:, I couldn't seem to find a maintenence reference to it.

I change it every other Oil Change . (basically every time i change spark plugs) its cheap and easy. why not?

That's an overkill.

Try Redline oil instead of Mobil 1.

well... i'll do it next time. Are you suggesting I drain it? And the use the Redling oil?:paranoid:

You change spark plugs every other oil change???

Yes, drain it and use Redline synthetic.

Haha, I don't know where you guys have heard to change it that often... Basic maintenance says every 60-80k or so. Doesn't need to be done often at all, changing it with every other oil change is a waste of money. And why would you change your spark plugs every 6,000 miles? Right on the car it says platinum tipped should be changed every 60k, a simple check every now and then should be fine.

he didnt hear it anywhere. its just how he does it.

bard probably picked that up wasteful habit from zwrecker.

Apparently I should have explained myself a bit better when I said 'overkill'.

yeah I do, they are cheap anyways RB loves the copper plugs. so 3$ each is not bad at all. 20$ spark plugs NGK Copper, 20$Gear Oil Mobil 1 Synthetic, 5$ Oil FIlter OEM Nissan. and about 1 hour of my time.

He's running synthetic so it's prolly a bit more than 6k miles... How far between oil changes Bardabe?

That's crazy but hey, personal preferance is personal preferance.

Myself I use platinums, change em every 70k or so and change my synthetic oil every 7500 or so. Depends on color of oil and engine performance really. If I start to hear more noise from the engine bay than normal I'll change it earlier.

ummmmmm
 

wait, are you saying you DON'T change your spark plugs every other oil change?:075:

I change it every 3K miles. I keep maintenance my 1st priority. my car dosent see the street much school --> home --> School --> Home. Track time once in a while. never gone to a meet. as well how can I put it.

Trafic enforcement + Meet of alot of modified cars + RHD =PWNED

yeah but there is a thing known as over kill... sometimes fluids need to set in... adapte to there surroundings.... i would chagn emy fluid every 15k probly... that way its usually always fresh but does get time to set in and such

Considering that would be like changing my tires every 20,000 miles whether they were bald or not and just as cost effective. Nope, I like money. :D

Ok, now you are saying you get 'z' rated and above tires to last more than 20k miles????? what world do you live in, or is it your grandmother driving your Z?:unibrow:

Southern California. We've got this stuff called pavement and concrete, usually it's nice and smooth. Plus my wife won't let me go to the track.....I'm abused.

I can usually get around 55,000 miles out of my tires if I rotate them regularly and keep the PSI in check. Not running over screws helps too....picked up my 3rd one last month, same damn tire too.

yeah well, gotta love living in southern california. LOL

each 60k...........................

I'm pulling so much camber in the rear that I get 15K IF I drive normal. when I go to track events. well my gas mileage and tire wear is horrible. I really need to get a fender roller to get my camber back to spec.

At 3.65 a gallon.....yeah I'd do it. lol

This crap keep sup Im going to have to garage the Z and get a Prius or something equally gay...I mean...fuel efficient.



No, I meant gay.

lol if I don;t drive my car like I stole it every day I get pretty decent gas milage. (26mpg) when i hit full boost oh my goodness. (last time I filled up, hit a few full WOT Runs and filled up on the next gas station) I calculated 8MPG at full boost. needless to say I don't drive her liek I stole her. + I have an accord for a daily. but that gets just a little better gas milage (31) but it has cool features like AC and a Heater. lol
