The gas mileage thread

[colonel6632]

i was surfing around the internet and found this adobe file with "tips" on increase your gas mileage. some of it i agree with, some i'm not too sure about.

what do you think.

personally, i get around or better than what the alero is rated for.

things i have done from the list include
NGK spark plugs, K&N intake, Seafoam regularly, Full synthetic oils, High tire PSI, aluminum rims.

now the synthetic oil, i never believed it to really make a fuel mileage difference.

My mileage is

City, 25-27mpg (this is usually hard driving, not driving like an old lady)
Highway, average 35mpg. but have gotten 42 on a few occasions.

what i average in the alero, 30-32mpg mixed with small town driving (lots of stop and go) and highway driving.

23 highway.
18 city.
1 angry driver who has tried every tip to improve fuel economy.

[wrestlingandrunning]

let's just say i get the same gas mileage in my 20yr 300zx as i do in my alero

[[ion] C2]

31+ MPG highway
20-27 MPG city (depends on how aggressive I drive.. it's very tempting)

Worth noting, my instantaneous MPG is 1-2 @ WOT

I get 20-22 city, then again I drive with purpose

[cavaliers60]

I drive average, and get about 20-23 mpg.... Sucks..

[Cliff8928]

I get 26 with the Ecotec and 19 with my poorly tuned 3400 driving to work and back.

[cherrington17]

26-28 hwy
20-24 city

3400

[JLw7123]

i get 20 city and 26 highway

i get 34-36 mpg with my mazda 626.

and i don't drive like an old lady.

no thoughts on the different tips though?

like lowering your car which makes lower air dam, or the stiffer shocks/struts.

in theory it makes sense, but i'm not sure sure about it

[Alerojester]

ok if you think about it lower your car you have less air going under your car to push your car back, if you think about a 4x4 truck what's the milage there? its like maybe city 8 and highway is like 12-15 look at it that way

[Chris2000]

I drive all city and I get about 250-275 on a full tank.

2.4 LD9.

drafting.

i can get 60-100+ extra miles per tank that way.

only works behind semi-trailers. modern cars don't draft for crap, and don't move fast enough to get any benefit from it.

I usually get around 37mpg with my stock engine and heavy chrome wheels. Doesn't hurt that I drive across the straightest and flattest section of road in the world haha. On my last trip during the summer i went 615 km before refueling and it still had 3-4 litres left in the tank.

[robalero]

so according to my readings im avging 40 mpg ( 80 highway 20 city ) on my 2.4L WAI new AC Delco spark plugs 5 speed tranny ( I gotta change my fuel filter soon too ) I wasn't expecting to get around this for fuel mileage but im deff not complaining I was expecting worse

[Ttop191]

ur funny guy.

[robalero]

I probably did it wrong myself, but I get roughly 550km to 600 km's on a tank of gas which in miles I really have no idea

[cherrington17]

there is NO WAY any alero EVER gets 80mpg highway. even 40 is pretty unbelievable.

i think you missed a decimal place in your math somewhere
