What kind of mileage can I get out of a 1994 Pontiac Grand Prix
I have a 2-Door 1994 Pontiac Grand Prix with the 3100 motor.
https://www.gassavers.org/garage_imag...5hl219vdh7.jpg What can I do to maximize fuel mileage for this particular vehicle? What kind of MPGs can I expect to achieve with a 1994 Grand Prix. Thanks in advance! |
this motor shines on the highway. that said, IF you drive mostly hwy miles 30mpg is achievable. if you drive almost entirely hwy, you could reach 35(w/ some mods).

do a warm air intake.. also try extra pressure in your back tires i do 36 front 42 back for good handling, anyone have any idea if 3100 had a map of a maf systemM if map you can do a warm air intake with results. also aerodynamics on your front bumper would help

hey bowtie guy, are those performance headers on your bugsy engine?
|
What mods would you recommend to improve fuel economy? I have a K&N air filter, but thats about it.

take a look at the stickied tips for milage improvements. I've found tire pressure is the biggest factor in mpg followed closely by driving technique.

I agree with previous posts... Tire pressure (don't exceed the tire's maximum, which is marked on the sidewall; and don't go lower than the car's recommendation, which is printed on a label probably in the door jamb) and driving techniques are the most effective ways to save fuel, and also the most cost-effective.
I don't think a manual transmission was offered in your car, so those techniques are out, but we'll talk about what you can do with your automatic. Don't accelerate too gently. I like to lay on the go-pedal pretty heavy and then lay off it to trigger a shift, then lay on it again (not so much that it downshifts, obviously). Keeping your RPM down and your throttle open is an effective technique but difficult to do with an automatic. The 3.1's decent torque helps. Try to avoid needing to use your brakes. If you see a red light or a stale green light in the distance, take your foot off the gas now. You may even need to brake a little immediately. Try to roll through at the highest speed possible. Same for turns...enjoy your car's handling (when safe and legal). Any time you use the brakes, you discard energy that you've already burned fuel to make, and then you know you're going to burn fuel to re-accelerate. If you just keep that inertia instead, you won't have to re-accelerate as much. Do these things only when they don't compromise safety or legality. Those are a couple tips for getting started. However, by far the most important thing is to track your fuel economy accurately. Enter your car into the Garage section of this site and start a gaslog. When you get gas, let it click off normally and don't top off. Try to get gas at the same pump each time, if convenient; that helps make individual tank measurements accurate. Keep notes in your gaslog about what you did. |
from his it looks like you have a map system

Canada Member No.: 551 Car Type: 1995 Beretta SS the 2.2 and 2.3 used MAP sensors.... same as the 3.1.... from https://www.bstuff.com/index.php?showtopic=4049 yea a warm air intake setup would work on this car from what i can tell considering your exact model has a map sensor and a seperate intake temp sensor on my car i get an extra 4-5 mpg highway 6mpg city with a warm air intake setup i have a gm from the same time period so it doesnt surprise me to see them using the same setup.. check out my gas logs all you need to do is somehow get hot air to go into your air intake (leave the AIT sensor intact!(this is important)).. and voula... you car will use less gas because hotter air is less dense(less air), and your computer matches the fuel/air ratio in response to this by using less gas... I swear this works.. look up project84's saturn.. ect |
I always suggest tire psi first.
Next, get your car tuned up, and I mean well. New filters, fluids, plugs/wires, pvc, etc. |
