Synthetic? or not? at 98k miles never changed it, was looking at Valvoline synthetic DOT 3 and 4 from autozone.

 

With the mileage on your G the only brake fluid I'd use would be OE from Nissan, you don't want to shock your system too much....

i agree with the comment above. i have been using valvoline synthetic for a long time now, when i upgraded to my BBK. i would def use the OEM stuff in your case.

 

REALLY? I didn''t think it would have matter,,, Thanks guys, I guess I need to make a stop at the infiniti dealership

i was just going to replace to rotors and pads and prob suck most of the fluid out from the engine bay and refill it with the new fluid.

 

With 98k miles I'd flush the fluid instead of adding OEM or anything.

Valvoline or Castrol syn DOT4 is a good replacement. Just taking fluid out of the reservior won't do you much good.

 

So the one at autozone.. valvoline dot 3and4 is good for my 04 coupe with brembos?

 

+1 with that mileage, fluid should have been flushed twice already.

 

so nissan or valvoline?

 

if you flush the system both are fine

 

Just go with DOT3 anything. I used Prestone.

Flush until it's clear! I was on OEM fluid until 95k and it was pretty bad.

 

You mean DOT 4, right?

 

^ nope, factory service manual calls for DOT3

 

I picked up some ATE super blue over the weekend, far from the best but it's DOT4(backwards compatible w/ DOT3) and the different color makes it easier to identify when it's fully flushed

 

Why far from the best?

 

ATE fits the bill and then some, but from an on paper persective, MOTUL, CASTROL and one or two others have better wet and dry boiling points.
