Ive got a 1.6 litre 2000 model protege, ive got CAI and Ive got a uni filter, plus i use premium fuel plus octane booster altogether my octane rating in the fuel i use is 00.... i get 670kms (dont ask me how many miles that is) out of a 47 litre tank that is on the high way with the air con on. Since i put the unifilter on i have noticed i get another 30-40 kms out of it.. plus aswell i get more power, also i dont know if the muffler i got on does it any better either.....

sorry i didn't answer your question... a bit wiped... .skool ya know...

i get about 35mi/gal... someitmes more for big trips, someitmes less for more short hops. 32-35 is about typical

I get 11km/L. I usually fill up 46L and I already have around 510km on the trip meter.

I got 608 KM on my last 54L that i filled up, yes i drove at least another 20-30Km with the fuel light on.. but that's still pretty good.

I did find out that i used to only get 500-515 km when i had my air vents set at defrost, defrost/foot, foot position (the a/c compressor turns on even tho the light is off). but now i just set it at foot/front and just front (ac won't turn on) and i get significantly MORE mileage.

I also have an Ractive intake.

350km with 1 quarter tank left so I should be getter 450km... my car is 2200kms old.

P

I get 540 with 47 liters. That's alright ain't it? I have no intake. It's all stock.

All you guys that are only getting 550-600 kms out of your car tell me what your doin wrong, im getting 650-670 out of me mazda with 00 octane rating fuel and a simple UNI-FILTER, you guys must be running 93 octane and have a standard filter....... the fuel i guess is more expensive but it it sits on the highway better and it idiles better hehehe

Those of you that are running high octane gas on a low compression, naturally asperated engine, don't understand the meaning of the octane numbers.

The higher the octane, the slower it burns. This is to keep from knocking/pinging from detonation. This is a problem with either high compression or boosted motors.

Lower octane will burn faster and more complete in an N/A motor like which comes in our cars from the factory. You will have more unburned fuel exiting the engine with a high octane gasoline.

Unless you have changed the timing, compression or added a power adder of some sort, stick with the low octane. You'll get better mileage, more HP and keep a little extra change in your pocket.

Just make sure you use a good brand gas and you should have no problems. I don't know about Australia, but the US has very strict standards for even the lowest of octanes.

ive pushed my p5 (55L Tank) to around 580kms on a full tank, when i filled up i still have 5L in the tank so im assumeing 11.6KM/L so that means i still coulda gone 58KMS. So total trip (runing down to vapor) 638KMS. this is city kms BTW

engine mods that could/would affect the millage are

Sparkco wires
InJen CAI
Catback exhaust 2.25" with an Apexi N1
(dunno if this changed it at all) Hyperground wires

i usually rev to 3.5 and a couple times to 5 everyday

How is this for fuel economy
 

OK. First off, this is my first post on this site. Nice to belong to a like-minded group :cheers:. Now, I own a 1999 Protege SE. I too live in Canada. I know that my car only has a 1.6 litre, but listen to my mileage. I commute to work from north of Toronto, Ontario to the downtown core every day (65 km one way). My trip is 95% highway travel, usually in traffic, but some of it is open smooth driving. I don't have the opportunity to stay in 5th gear for too long. I have been recording 700 km per tank of regular unleaded fuel. My highest recorded tank, earned on a drive from Montreal to Toronto was 739 km.

I used to own a Honda Civic SI and I never achieved mileage as high as I am with my Protege. Hint: If you do a lot of highway travel, you can still squeeze an additional 70-90 km from the time your fuel light comes on. I do it often. Nothing gives me more pleasure than beating "the man" at the pump. :p

If it means anything, I am purchasing a P5 this week. I'll keep you posted.

Go Leafs Go!!!

OK. I don't get it. Montreal? 'Go Leafs Go'? Location: Victoria? I'm confused. Help.

Re: How is this for fuel economy
 

to get 739 k's did you pump your tyres to 60 PSI or some thing

Well, I do a lot of highway travel. Also, I am a slow driver, right lane (in North America), 5th gear kind-of-guy. Usually I cruise around 105 km/h. I almost never stretxh my gears out except to pass. Add to this that I have 1.6 litre engine, without an air conditioner and you can see why I have such great fuel consumption.

However, in town driving is a different animal. I average around 500-530 km. What about you? What is your best mileage?

Ciao for now,

--leafsboy

yer i usually get around 500 around town, i also have a 1.6L but i gave an air con, that must take yp a bit of fuel... id rather pay a little bit more for fuel for the air con he he

bone stock manual using regular 87octane gas.
I get an average of 8.5L/100km this is mixed city highway driving.
(yea I keep a spreadsheet of my gas milage. This average is from about 1 year)

I get anywhere from 550-600km when the light comes on (normal non spirited driving).
