Let me start off by giving facts about my car and where I live and my driving style:

- I live in south fl, so its hot/humid virtually year round
- Manual 09 Z
- Drive like a granny(not an understatement lol)
- No tracking or racing(if you do thats cool)
-Sport pkg

So, from what I read, looks like I might experience some leaks but only for the first change because its "cleaning" the gunk out.. w.e that means. I just don't want the car to take a step backwards by switching I understand it better for the car but the whole point of the thread was to see if you guys have any input on if its a step forward by changing now at 66k. Anyone dare to give a straight answer?

Also as for the tranny fluid, I have also read and been told "If it ain't broke, don't fix it" I have never changed the tranny oil as mentioned above, I find the shifting normal but maybe I'm just a dummy lol what are some symptoms of our Z's screaming "I need a tranny oil change please!"? Same question refers to the VLSD.

As for brake pads I ordered: "Wearever Platinum Premium Ceramic Pads", if theres any reason I should return it and get something else by all means let me know.

The way you drive and assuming you change on normal internals (3750 for engine oil) recommended by Nissan, I don't see any reason to change to synthetic. I run synthetic in every car after the first engine break-in oil change. It should be noted that I drive my cars hard. Maintain them well, but definitely drive them as intended. After all they are sports cars.

I highly recommend changing all drivetrain fluids as per manufacturer recommendations at a minimum, whether that's the oil or car manufacturer recommendation. I change my tranny oil every 30k, well I'm going to 15k now but only because changing the fluid requires me dropping the turbo. After I dropped the rear diff the first time and saw how filthy it gets I made the decision to change it every 15k too.

All in all the way you drive, I would just use Nissan OEM replacement fluids/parts.

This! Anyone think this could be a consistent problem in a Z with 66K?

I'll start by saying this is all speculation and I have no facts or backup for this statement but I would hope that this type of leaking is a thing of the past. My SC300 was a '96 and synthetics were not as common back then. I kind hope that there have been improvements in both the seals used to account for synthetics and in the actual synthetics themselves.

That being said I'll never switch to a synthetic later in a cars life just because it bit me in the past.

no reason to get hostile because you disagree. Would appreciate you not badmouthing me. just saiyan. If you wanna bad mouth, come on out to manassas park VA I would be happy to teach you some manners free of charge "except your inevitable hospital bill".

Bitch comments from others aside, it seems I was wrong. oh noes, end of the world. oh wait, how about I just admit to it and we move on. No need to be childish cunts about it. defense justified.

Are you serious right now? am I really sharing oxygen with people like you. :shakes head:

No reason to get hostile. Threatens to put you in the hospital.

unfortunately its pretty status quo for him

Why is this BS tough guy garbage allowed to continue on here? I guess it is just par for the forum course. But it gets old. As the great philosophizer guy Jay Z once penned, "You know the type... loud as a motorbike but would bust a grape in a fruit fight." I am sure I am not alone in being annoyed by it. I hope I don't get threatened now to. I would surely live in fear.

From 32 years oil experienced 370Z driver something you should all know

Engines produce byproducts of combustion regardless of the oil it should be changed at regular intervals. I've seen conventional oil outperform in the racing circuit over synthetics. I run 5w 30 full synthetic in my 370Z and I don't consume any oil at all whatsoever, I change it though every 5,000 miles. Because of the byproducts of combustion such as hot cold hot cold creates moisture that's why we put dispersants in there to keep everything suspended. There's a whole list of others but I'll just leave it at that

Grave Digger. This thread has been dead since July of 2014. Should have left it there.
