gas mileage difference

[ChadCy75]

I was just curious if anyone knows how big of a difference in gas mileage there is between an Alero with the 3400 and a Buick Park Avenue with the 3800? Any major differences in the power? I'm guessing there won't be too much of a difference, seeing as how they are both 90 degree V6's, but even so, if anybody actually knows the difference, I would appreciate your knowledge!:rolleyes2:

Um, the LA1 is a 60 degree engine....

Check out this gov't site, it'll give you a rough estimate your looking for. Plus you can look up other cars you got mpg questions about.

Thanks for that link!

the 3.4 is a 60 degreee V6 btw. but they get about the same mileage really.

This guy has a 90 degree 3.4 and pappa smurf has the V4, wow what else can you get in an alero???

Thanks for the info. That's what I was more or less thinking, since both motors are GM V6's, but sometimes it can be a huge difference in the MPG's. Also, those with the 3400 motor, where is your tachometer when you go through those first few gears? I only ask, because my Alero hits about 3100 RPM, where as my dad's car, a Buick with a 3800 only hits about 2500, at the most. My cousin has a Pontiac Montana van with the 3400 motor, and it changes gears somewhere around 2500 RPM also. Any info about this?

sorry to give the obvious answer Chad, but that has a lot to do with how much throttle you give, more throttle=higher shifter point

Also i went to that calculator site, and i don't know about anyone else, but i get around 34-36 to the gallon usually if i keep it at 65 (yes with the LA1). not really sure how i do it, but it might have something to do with the CAI and pacesetter Cat-back i've put on it :D

those shift points aren't the engine, its the transmission, and where the points are programmed into the pcm.

with "hptuners" you can change those, if you wanted to.

Wow, I like those numbers. I can baby mine and still get only 28.5 MPG. I would gladly do those mods for the improved mileage.

[Lucalare]

well, i'm not sure though, because i got 32 once back when it was still stock. I guess i got a winner.

[AlbinoMonkeyRat]

heh...that link says I should be getting 28 Highway. I'm getting that on average, and I thought I was doing bad. lol nice.

[cherrington17]

old rules (when i bought it) i should have got : 20 city... 29 hwy.

new rules: 18 city... 27 hwy.

i average 26.5ish. I speed (65+) and am outta alignment. I'd say i'm doing ok. :lol:

[wrestlingandrunning]

I got 21mpg on my last tank :( I don't drive it hard either.
