I'm everyone's been asked this question at least once. But seeing as how most engines made in the past decade are engineered to take both even though a lot of them recommend using only premium. So whats your 2 cents about about this topic?
What kind of gas do you use in your iQ? Premium or Regular?

Just go with whatever the manufacturer recommends. They always have actual data to back up their recommendation. Its not like they have a stake in the gas companies. If that was the case then every manufacturer would only recommend premium.

I use regular ol' regular like I did in my Yaris. This is great after owning several MINI Coopers that seemed to like drinking premium. Glad to get out of that scene, and the Yaris was seeming a wee bit too big for me. I generally fill up once a week in my iQ, maybe adding 6 gallons or so. Sweet!!
I would just use premium. Not because people say you get better mileage. Not because people say it makes it run faster. But mainly because most premium gases don't have ethanol mixed in. Also premium gases can remain stable in your tank way longer than regular gas. Meaning if ever for some reason you're unable to start it up for a long time it wont gunk up the fuel lines.

We have all unleaded gasoline. The "regular" is 87 octane "premium" is 91 octane. Glad to say our iQ's are designed to run on regular gas. =)
Not true. That's a huge waste of money to use Premium in an engine designed to run on Regular.
I would NOT Run Premium in your IQ, It is not good to Try going back and fourth between premium & Regular Gas, in a car designed for Regular gas, (like the IQ)
The ECM/computer adjusts to the fuel that a engine runs on.
while the engine is suppose to Run on Regular gas switching to premium, or back and fourth to different grades of fuel could cause you some problems, like possible pinging when changing back to regular, while ECM is adjusting back.
It is possible, as the IQ has a high compression engine, and the ECM does can adjust to compensate.

Gas octane?
I will try to enlighten you....unless you live at high altitude, I'd be for
using 91 octane rating.....even your manual states to use 87 mid-grade
or higher. It states that using lower octane would also lower your mpg.
Why you ask....when you read your manual, you will find out that our
1.3L motors have a 11.5 to 1 compression ratio.....that's getting up
there close to race engine levels. The higher the compression, the
higher level of octane is needed for proper operation and performance.
I was quite surprised when I read what our compression ratio was in
this little motor of ours!
If you live at high altitude, you could probably get by with the 87 octane.
Just some food for thought......but I will be using the 91 octane, and I live
in the Denver area of high altitude Colorado....I just think it would be better
on the motor in the long run and help the mpg a little??

I've been using the "Cheap" gas 87 octane and was wondering why I'm not getting the mpgs in the 40's like a lot of people here. So on the last fillup thought I'd try the midgrade 89 octane. I got 40.2 mpgs on the last fillup with 87, I'll see what the 89 does on this tank but I think I should just stick with the 87 and leave it alone. Theres 1670 miles on the car now and it seems to be improving with each fillup.
I've been filling up at the cheaper mom & pop gas station, maybe I should start using Shell as well.

Well I got that 40.2 mpgs using 87 then I filled up with the 89 and that tank gave me 33.2 mpgs. I'm thinking Damn.....so after that tank I went back to the 87 and got the buggy back up to 38.1 , guess I should have stuck with the 87............Have any of you guys had a similar experience ?

You know what my friend ? I believe my Buggy is broken in enough now and I'm like you and can afford the gas. I'm thinking that I should enjoy my MOONBUGGY for all it has to offer instead of looking for all it can give. To hell with the ECO light and it's time to enjoy it instead of stressing out about how much better it can do !
See what you did ! Ha Ha
