After that amount of time the lube was not performing up to spec, even if it looked good. Maybe still good enough for a grocery-getter (most trans/diff lubes are pretty tough) but not what I would want in a sports car, especially if driven hard.

It's a good idea to change all lubes after a short break-in period (say, 1000-1500 miles for motor oil, 10-20k for MT and diff).

But opinions on lubricants (and car audio) are like a**holes - everybody's got one.

But the manual says different. It's obviously the final word on everything and you can't possibly do better and anyone who says anything different is just some jackass on the internet.

If you will re-read my last sentence, you will see I am not claiming to be a professional, just stating my opinion. But I do have a lot of experience with lubricants in an industrial setting. I'm definitely not an expert but I do know a little bit more than the average bear.

The only professional recommendation that really matters is nissan's. Not the dealer even, Nissan the manufacturer.

People will make up many unnecesary things to do on their cars. If they are having fun doing it, great.

This is the same Nissan that issued a recall for steering lock unit to replace them with another faulty unit? And the same one that will not recognize a problem with a CSC with plastic internal components? It is? Ok just checking

I think JARblue addressed that.

Yes, Nissan's recommendations are good enough for most DDs and the people that drive them. But many of us who have maintained equipment for a living know that ofttimes going a little above what the manufacturer calls for can greatly extend equipment life and contribute to the overall efficiency of the system. Especially with equipment that tends to get pushed hard.

I guess that all depends on one's definition of "unnecessary". I think the little bit of extra I spend on changing more frequently than recommended is money well-spent in the long run. YMMV.

FWIW: I think the 3750 oil change interval that Nissan recommends is on the conservative side and, for many drivers, could be extended to 5-6k with no problems. But, once again, that's just my opinion.

that's wat ive been saying. even the very basic maintenance is fine for most weekend only driven cars.
if you track your car that's outside nissan's normal routine so it'd be wise to do more frequent changes.

most people dont track their Z's...

this thread is redundant and stupid
