Trenz Grill & MPG
I'm sure this is just a coincidence, however, a month and a half ago I installed a Trenz billet grill and my gas mileage has dropped about 1.5 mpg (from an average 23.5mpg to 22mpg). I've always been **** about keeping track of my mileage on all my cars and for the last three tank fill-ups it's gone down. Temperature has been the same (hotter than hell), driving still the same and just went over 10K miles.

I have the Trenz too, actually just polished it up with Mothers aluminum and mag polish and WOW it looks brand new again. As for your MPG thing...

That's a hugh different from just a grille. Have you switch gas station? Has the gas station switch distributor? Is it different formular, richer in ethanol?

Check the grille sensor...when you removed the stock grille and put the Trenz one in, the grille sensor wont detect the aftermarket grille. The grille sensor monitors how much air hits it, and then recalculates the Air/Fuel ratio...better put the stock grille back on.
You know i'm jokin', right?

Must be from the awesome aerodynamics of the trenz grill

The lines in the Tenzo collects and holds more air therefore adding more weight, therefore crappin on your MPG. The stock is more aerodynamic and actually pushes the air out of the way due to Nissan's R&D and should therefore be placed back asap before your problem gets worse.
true story.
really it's not, I don't know what to tell you guy.

The grille sensor is seeing more airflow due to the added turbulence, therefore sends a false signal to the ECU requiring more fuel for the injectors.

Has the wind changed direction and is now head-on? That would account for the 1.5 MPG drop.
Another theory, the added weight of the Trenz grill over the plastic of the OEM grill. Hmmmmm.
Too confusing so I'm just gonna...

I agree. He should chop one hand off to provide a suitable trade-off in weight.
