need help diagnosing immediate 2mpg drop in fuel mileage after routine maintenance.
#61
Interested to know if your milage stays up. I just changed the fluid in my
Diff(75w-90 redline) and trans(MT-90 redline) wish I had done a search about some of the complaints with the trans fluid. I've noticed the stiffness in the trans when cold figured it was due to the actual temp changes outside right now, is the stiffness all year round or just when cold. I've used 75w-140 redline in my 85 FB and it actually helps in the cold weather.
On another note do the 350z's have fuel filters? I was told that my 07 doesn't. All that it has is the sock in the tank.

however, i've now noticed that the shifts feel slightly better overall switching back to oem stuff. it's got to be something about the viscosity or the additives. it also smells differently than redline MT90.
i drove a little more today and the nav is consistently seeing 19.0 or higher which before would never read past 17.4. i still want to finish out the entire tank before saying that it definately helped or not. i've had that combo of fluids for ~500mi before getting fed up and re-swapping oils.
as far as the fuel filter, i was told the actual filter is inside the tank? i'm not sure why that is. maybe today i'll pick up a haynes manual lol
