Gas Mileage FAQ

[Sinister]

Probably so! I guess the engineers have to find a balance between having some power on tap for hills, and not having the rpms TOO high for fuel economy.

probably why we're starting to see 7 and 8 speed automatics.

probably why we're starting to see 7 and 8 speed automatics.

Or soon there will be only hybrid engines, which will have plenty of power and decent fuel economy.

Like in my country where i from originaly(Ukraine), we have cars that have both gas tank and natural gas tank. And we switch when we need more power to the regular gas, when it's no need in power we switch to natural gas, it's twice cheapper than gasoline, and about the same advantages. Usualy you start the car when it's cold on gasoline and then switch it warm to natural gas. I don't know if US have it, never seen it here....

That's really interesting! I didn't know that happened...

I know of strictly natural gas vehicles, but I didn't know that there were any hybrids.

Maybe because you live in USA and you don't have it here. In Ukraine 50 percent of TAXI drivers use the natural gas and gasoline powered vehicles, they make more money that way....
I wish i can put the natural gas in my impreza, all equipment about 700 $, but it will save you money 1/2 on gas.

pretty neat!

Can't believe it's been a full year since i bought the 06 WRX.
10,000 miles. odo showing around 33,500 now...Runs and drives as new..... it averages 23-24 mpg... if i use it to commute i drive from 5000' to 7000' to 6000' and same on the trip home [doh'] and ALWAY'S do at least one full on 1st to second power shift.
Can't complain... One vaca trip we got close to 29mpg fully loaded with AC on...Whats not to love..Just turned 58 on July 15th.

"Fuel Catalysts" I'm really curious about this stuff - haven't tried it and I'm not recommending it. Senior charger forum guys are using it in 89 octane for a 93 octane tune and claiming less FLCK and improved mileage (substantially). I know we're all gun shy of snake oils, but sometimes new things come along.... See post #2 mainly for this thread.

Pretty cool

Awesome!

2006 WRXs rock! 2005's suck!

i'll have to second this. so far on my trip, the best i've gotten in my 06 is 28.75 mpg. this is with a couple of WOT coming out of toll booths. Hoorah!

It's seen here in the US, only in custom conversion kits. I have two friends with custom conversion kits in their cars and both operate similarly (gas on a cold engine or if you want power and the other type of gas on a warm engine when performance isn't needed). One is some kind of natural gas conversion, like what you're talking about. The other friend gets leftover grease from fast food restaurants and she has a second tank in her car which can take filtered grease. Once the car has been started on normal gas, she can switch to used grease.

The WRX Mileage Thread

[Sinister]

good idea. Don't have time now, I will later tonight or tmrw

I got a 02 WRX, and took a trip down to VA this past weekend. I got 366 or so... but then it's a WRX and you prolly have an STI which is 2.5L but i am trying hard to get 30mpg on the highway.... somehow magically. i actually got 28.5 but thats when i drove at 65mph tops. do spark plugs help gas mielage?

I made over 350 on a tank.

So I decided to drive like a normal WRX owner for a tank, and got 270.

So 80 miles on a tank is a pretty big difference!

With gas prices up to 2.80 in some places in Colorado... I implore some of you to re-read my FAQ!

If they're old, then yes they can help.


(I have a 2006 WRX which has the same displacement as the STi... I do have the 2.5L)
