MPG Improvments needed!

[94-302-vert]

How about list ways we know to increase the mileage on these cars... My car has been stuck at 19mpg since I bought it.

I would have thought that the exhaust, gears, lowering (mostly highway), oil separator (no oil in it yet ~100 miles), etc... something would have effected my MPG. Any thoughts besides slow down, put the top up, etc?

19mpg in town? Or highway? That's not bad dude.

I wish I was getting 19mpg. My last fill up was 14mpg. I think it will be worst this time since I have 80miles and half a tank.

 

[94-302-vert]

19mpg combined. Mostly highway.

My drive consists of ~15 miles of 50-60 mph country road, 1 mile of stop and go (maybe 3-4 lights, 45mph between them), 20 miles on the highway (70-120 mph average) then about 3-5 miles of 40 mph backroads. then reverse in the afternoon...

Tune up, new o2 sensors, tire pressure

That's not too bad, I was getting around 17-18 before the heads and cam. That was half highway, and half in town driving. Since the heads and cam, I've driven 39 miles and burned nearly an entire tank! But my MAF is crap and I'm running pig rich, not to mention the massive fuel leak I had when I forgot to put the gasket on my new fuel pressure regulator, lol.

Bump the timing, if you haven't already, and give it a good tune-up including cleaning the maf, ect. The gears hurt gas mileage on the highway.

I haven't touched the timing yet.

I should set it at 12*?

It runs Rich too, I can smell it with the O/R pipe pretty bad soemtimes.

02's are less than a year old.

Proper tire pressure, clean mass, change fuel filter/plugs.

HAHAHAHA u think 19mpg is bad i have never gotten anything better than like 13 or 14 even when it was dead stock with 90k, i wish i had your motor, gas is 3.02 for 91 octane here in cali right now.

It runs Rich too, I can smell it with the O/R pipe pretty bad soemtimes.

That smell's from the off road h-pipe as the unburned HCs are not being converted in the catalytic converters. When my brother ran an o\r h-pipe when he was stock except for gears and not running rich the exhaust smelled more strongly.

If you want better gas mileage convert to stock and throw in some 2.73 gears

Shell gives me better milleage than the cheap brands, chevron or 76. It's actually cheaper per mile than any of those brands at least on my car.

1. Find a 94-95 3.8 V6

2. Buy said car

3. Swap engines

Gotta pay to play.

granted mines not a vert, but i get 20-21 beating on mine and 23-24 being easy on it, Ive never gotten under 20. my timings on 12(it got better before i turned it up, im going to be turning it down), i have 1 5/8 headers, or pipe, flows, kn, smog bypass and 180*, is mine above average or about right? BTW stock gears and 5 spd

oh and i was getting 20-21 no matter how i drove it until i cleaned my maf

 

[DarkProphet]

I wish i was getting 19mpg. Just be thankful u dont have to run premium and only get 10-13 mpg.

 

[Crash Gordon]

my sentra only get about 10-12 mpg. My stang gets 18-20mpg, At least it did 5 years ago the last time I drove it.

Like said above tire pressure. A 3psi deficit can translate into a 10% decrease in fuel economy according to engineers at Pirelli. Plus your tires wear better.

 

[Engel]

my stang gets about 14 in mixed city/highway and 19 on interstate

 

[TheDamned]

i get ~ 15 mpg city and i'm BONE STOCK, FOR FUX SAKES
