Hiya guys, I am new here so be easy. I have a 2004 Suzuki Swift which correct me if I am wrong is the same as the Aveo. It is a 5 speed.
I have seen varying messages regarding the fuel mileage of the Aveo, overall though it is good. I was actually wondering if the ethanol based fuel is worse for the car or if using say 91 octane with lower to no ethanol is better for fuel mileage?
I run 87 octane with ethanol in mine and I do just fine mileage wise. Driving technique is has a much more drastic effect on mileage than ethanol fuel. I'm sure no ethanol gas is a little better on mileage, but you probably won't even be able to tell the difference. Higher octane fuel is also a waste and won't give you more power or fuel mileage.
You can't use fuel with more than 10% ethanol content. The Aveo just wasn't designed for it. As for fuels, anything higher than 87 octane is a waste of money IMO.
thanks guys, it wasnt for the power I just dont wanna ruin the engine if I put gas with higher ethanol content and not get good mpg
I run 93 exclusively, I get the best mileage out of it, and the car always just feels better with it, but then again, it is tuned for 93 octane.
Where'd you get it tuned?
It's tuned by Trifecta based out of Washington, and I must say, every aveo needs this, too bad it only works for second Gens.
That's awesome. What improvements did it make?
I've never had the car dyno'd, so I can't say how much power I might have gained, but with my tune, intake and exhaust done, I can definitely say acceleration and throttle response is vastly improved. My car could barely do 90 before everything, and now it tops out around 125. I never have any issues keeping up with traffic, passing at higher speeds. My gas mileage is slightly better even with the slight performance increase, and my shifts even feel smoother (autotragic transmission) its really just an all around much better car now.
This is why I don't miss the Aveo.Quote:

put diesel in it. then u can get a new car
who are talking to?:confused:Quote:

Just changed to Shell 95 (RON). The motor was re-tuned last week, performance is amazing! Economy is better on 95, see Garage for fuel consumption.
As most of my trips are less than 5km, I am now adding REDEX.
The Aveo's Owner's Manual Recommended Fuel you use regular unleaded gasoline with a posted octane rating of 87 or higher. If the octane rating is less than 87, Gasoline Specifications (U.S. and Canada Only). At a minimum, gasoline should meet ASTM specification D 4814 in the United States or CAN/CGSB‐3.5 or 3.511 in Canada. Some gasolines contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). We recommend against the use of gasolines containing MMT.

i have a first gen and have tried 87 89 and 91 didnt notice anything 91 gave me slightly better highway milage but wasnt worth it and my car tops out at 121 its scary and needs a lot of room but doing 80-100 isnt a problemQuote:

Did you go with Trifecta Performance for your tune?Quote:

I run 95 unleaded because thats the only unleaded petrol they sell in South Africa

I use shell 87 octane, paying $3.41/gallon, and I drove 100 miles and it brought me down to between 2/4 and 3/4, since yesterday..
I drive a little bit on the speedy side aswell.
Just a BTW for everyone on the thread, if you can find petrol/gas that has NO ethanol in the fuel (Chevron 94 Oct) this does effect the performance of the vehicle. Especially when accelerating up a hill under lots of load. The ethanol 'stretches" the fuel and its supposed to be only 10%, but we had a hose and fittings rep tell us that the tanker trucks go through hoses so quickly because the ethanol is a corrosive. That content is more like 25-30% ethanol in the fuel!
For what gas station? Ive only put shell gas n my cars sence day one and have never put anything elce in. Today I filled up with shell v power 93 gas and I can almost tell a difference but my car is idleing kinda low like below 1k rpm its usually right at 1 or slightly higher. .. dont know the mpg difference yet. Plus I herd the high octane eats fuel lines...
Lolwut. Octane most certainly does not eat fuel lines. As said above, ethanol does. I f'in hate ethanol. Although I am considering getting tuned for e85...
ok so running 93 in are cars is not bad but in most opinion its a waist of money?
does it not clean the injectors and what not?

id like to chip in here, i use shell 91 exclusively and when i did my testing where i ran each brand for 3 months to get a good average shell 91 with no ethanol netted me an extra 2 mpg over gas with ethanol.
I thought all gas had ethonal
nope, there is still pure gas out there you just have to look for it, not all shell stations carry it but most do.

Now in my f150 with it variable timing shell 91 nets me a good 5-7 mpg depending on which direction I'm going.
most gas is e10, some few places are still all gas but most aren't
Its why u wish i lived in the states. 15 cent per gallon difference between regular and premium. Oh and the 3.50/gallon. We are closer to 5.50/gallon here in canada
