Anyone use premium gasoline?

can you advance the timing on an aveo? Ill have to take it to my friend next week then and see what he can do, that would be interesting.

The only way to do that is to do the resistor mod either on the IAT sensor of Coolant temperature sensor.

But please dont.

lol hell no, who would use those stupid things

Definetly a touchy subject...

Your car is not getting treated by giving it a higher octane fuel... refer to google for more on this, also here are some links.

I'm not seeing the article I was looking for, but basically lower octane should give you more power unless your ECU is capable of compensating for the octane. Lower octane burns faster and therefore will give you a little more timing and hence power. If your car can compensate for the higher octane, then it burns slower, allowing more timing and more power.

Meh, I only fill up at Chevron w/Techron. It's really good clean fuel and I've never had a fuel problem with a single one of my vehicles.

Theres no difference between fuel from one gas station to another.

Did you know the federal government requires all fuel sold in the US to have additives that make the fuel burn more efficiently and cleaner? That "techron" stuff is Chevron's attempt to ADVERTISE THE ADDITIVES THAT EVERY SINGLE FUEL COMPANY ALREADY HAS IN IT. Some companies will add additional additives but the government regulates what they are allowed to put in and by how much as well, and since the fuel you get is the exact same no matter where you get it from, Chevron has very little room in terms of proportion of gas/additives to add more stuff.

It's called marketing...

And it's used to try and make people think you sell better stuff than your competitors even though you sell the exact same thing...

Touche', however here in AK quality of fuel is a big problem, where-as not so much the fuel but proper maintenence of the stations tanks. We have a big problem also with water condensation in the fuel when the temp drop into the severe negatives the molecules seperate, as if your car running like crap from water in the fuel isn't bad enough it will actually freeze in your fuel lines lol. Chevron up here cleans they're tanks frequently and treats all their fuel with an additive compariable to HEET. Diesel fuel is hell in the arctic lol.

man why do you live in AK?

I have only HAD to run Cheveron at one time in my life.

I had a GLH had problems running on anything lower than 92 octane.
And just sounded healthier on Cheveron.

Man, I love it up here. I mean the weather is severe, but it's amazing up here. I'm never living anywhere else.

i always use 89 from shell then about every three fill ups ill do 93. its to expensive to run 93 the whole time so yeah
