New guy here with Nissan Frontier in Florida
 

Just stopping by to say hi. Been a lurker on here for quite awhile, I employ a lot of the gas saving driving techniques but was interested in learning more about real mods.

5sp 4cyl 2.5L 2007 Nissan Frontier getting about 22.5-23 MPG right now hoping to increase that.

Welcome to the site. What mods are you considering? What have you done already?

So far, the only mod would be a hard cover for the bed (Undercover brand). Aside from that, I have been reading up on the proper driving techniques. I really want to get the UG first, so I can see the mods benefits as I do each mod seperate.

The ones I am currently considering:
-block off front parts in grill
-add front skirt (not sure the name)
-add side skirts
-wheel covers
-maybe new tires in future

That right now was from a few days of searching other peoples mods to trucks. I really have not seen much on whether or not intakes/filters or exhausts actually help. Engine mods I havent seen much of (pulleys or any bolt on parts etc).

So if anyone has suggestions on certain engine mods that might help pay for themselves let me know. I probably wont be changing the gearing, as I do occasionally need to tow my motorcycle.

Also, does anyone have any input on switching out fluids to help increase? A very quick search led me to see many people switch to synthetics during oil changes, and lighterweight gear oils etc. Microlon is something my friends have done, not too sure about it though.

Any input?

Thanks!

The only other engine thing I've seen referenced by some as good for engine efficiency is a wetting agent in the coolant reservoir. Some see good results from it, others see nothing. I'd say wait until you get the UG and your car is ready for a radiator flush to try it, at worst it's $5-10 wasted, at best some people say their system stays cooler with less fan action.

As for non-engine mods, I didn't see you mention increasing tire pressure. It's easy and you can do it right now. Some people go as high as 10-15psi over the sidewall rating. Adding a belly pan is probably pretty helpful on something as high as a truck as well, although I'll admit I haven't done much reading on trucks on here.
