Increasing Fuel Economy

[falloutboy]

Hi Folks,
due to the fact that the gas prices in Germany are souring high like heck.
I was wondering what parts would help save a little fuel.
Now I need around 15 L per 100km
with a price around 1.40€ ( 1.80$) per Litre (not per Gallon) not quite cheap :)

So how about parts, like the Other Guys Headers?
Adding the RSM turbo?
or new Cylinder heads? Or a low resitance CAT-Back Exhaust system?

So tell me ur Ideas
everything welcome.

go back to completely stock and buy a DHP tuner and tune your car to get better gas mileage


adding performance parts does not increase fuel mileage

[-Alero-]

mainly tune up items will increase your gas mileage as well.


-such as changing tranny fluid to a better type.
-changing fuel filter
-changing spark plugs, wires, coil packs
-synthetic oil
-WAI

stuff like that

[misslindseysue]

Don't change your tranny fluid to a different type. Change it if it NEEDS to be changed, like your manual says, otherwise leave it alone.
Otherwise, yeah, a good tuneup is the best you can do, keep your tires inflated and keep it waxed. ;)
You'll spend more money on mods than you'd save in gas, and if there were mods that really workd for economy, we'd all know about them.
Plus remember a/c takes power = gas.

Thx,
just wanted to check that.

But isn't it that you can move ur may tourqe in the lower rpm range, u save a fuel.
Or at least if ur driving in our German citys during rush hour.
Ohh these Manual tranny drivers how i hate em.
U gotta drive like with two foots, both gas and brake at same time. so that u can swimm with the traffic

[jamcllw]

You can get an MSD ignition. I notice 3-4 MPG increase but with it costing roughly $500 after all the parts you need it's not very cost effecient.

[FormulaNERD]

also, using the A/C wastes less gas than having the windows down :)

[misslindseysue]

^ True at highway speed. In the city, you're better off rolling them down and sweating (depending on the day, I suppose). The thinking being with windows down at highway speed you create more drag, so you need more gas then you're saving by not using the air. In the city you aren't moving fast enough for it to make a difference. Of course if you really want to conserve, drive everywhere with the windows up and no air. :)

Actually Turbo's increase the efficiency of your engine and save gas.

[Daytona]

^But what about opening up the sunroof and keeping the windows closed? Would that be better than running the a/c at high speeds?

[Vtolds]

And doing all the above stuff will cost more than just paying for the gas.

[pawzbear]

^ yeah, so they should all go buy hyundais, right?

so switching to a transmission fluid thats higher quality is a bad idea?

wow that sux :rolleyes:

i guess my Dexron III Royal Purple ATF was a bad idea :(

[misslindseysue]

It's so funny that you believe a label on a bottle is smarter than all the engineers that developed your car and all its components. I think you should be fine if it's Dextron III though.

[pawzbear]

^^ exactly. The stuff people pour into their cars these days is hilarious... We think we have seen it all.. but they never fail to amaze us at the shop. Most all of that pretty labeled fluid stuff is a ripoff or at least entirely unecessary.
this one time a guy thought he could recharge his own a/c at home...all he needed was this bottle of weird stuff he prob got off the internet. BWAHAHAHAHAH that didnt turn out well. he was totally clueless with cars anyway, so i will give him that.

[Redog]

I noticed that my mods help more so on the highway for good MPG, however in the city, I get maybe 1 extra MPG fully modded. If you're looking for fuel ecomony, heavy mods don't jusify it.

do a K&N filter, be should tires are at the correct PSI, use the a/c, windows down increases drag

yeah im sure people know that as long as its the right type of fluid its ok, i didnt mean a different type i meant a different brand.

and in the world of fluids (lol) many differ in very large ways or differ in very small ways.

umm if you're running 134a (most newer cars are) YOU CAN recharge your a/c at home :wtf: :emotlol:

yeah but theres the bottles, and a can tap, and having to find the low side port, and run the car with a/c full blast

that is way too much work :rolleyes:

[gre0481]

OK, I'm not into metric conversions for everything.




Your tires have an acceptable range for air pressure. I forget if OEM is 30, or 32. I don't go by that.

for my BFG 215/60/15's the max was 35. I kept em at 35 and had nice even wear the whole time. Improved economy, but less dampening.

I'd say you could run them between 28 and 35. Lower than 28 and you'd see some wicked wear after a time. 28 would not be as economical, but better dampening and performance.

Keep up your rotations, have your alignment checked now an again. Keep good tires on your car, change oil every 3,000 miles (us) :P

[the.saint]

I'd go with better breathing as well, K&N filter, that should give you a few percent better mileage, that is if you don't use that bit of extra power to go faster.
I live near the German border and work liturally ON the border (desk in Germany, chair in the Netherlands, no joke!!), so I like 200 kmh plus speed probably as much as you do, but when I drive only like 130,140 my 3.4 tends to consume approx. 10 L/100.

15 litres does seem a bit much....

[falloutboy]

All good points u emphasise here.
First off all, the 15L are city Traffic. fastest speed every day around 110km/h. average i gues something between 40 - 60.

To the window thing. Yes open windows drag air a lot. A/C costs around 5 - 10 HP Alternator around 3 HP (under full work) So Windows to get the air out, the first few meters. A/C while traveling at midrange speeds (windows closed for sure)
And to the question about the sun roof. Sun roofs drag very little air, AND make a better cycle of inside / outside air, then side windows.

To the Turbo / perfomance Parts. I think they can help save fuel. Dou to the fact that u alter the Tourqe curve more into lower rpms (not all performance parts to that), you need to stay on the pedal shorter and "lighter" than without.
JUST TALKING ABOUT ACCELERATION
Thanks to the automatic, u go off the pedal once o reached your wanted speed. And NO pedal pressed and rpm over idle speed means NO fuel injected. => saves fuel.

So enough for tonight, I gotto work tomorrow and need some sleep.
