I usually give Scoots a diet of Top Tier 87 Octane Gas. (I usually get Shell because of the 10 Cent Discount though our local Grocery Chain) You Really don't see the Benefits of Higher Octane Fuel unless you are driving a car that's been Tuned to reap the Benefits, or if its a High Performance car (like a Camaro ZL1 or a Corvette) that was Designed for High Octane Fuel.

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'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.

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 problem

I take Pertamina "Premium" gasoline 88 Octane + Iridium type spark-plug, and I got 14 km/L (highway+city)..the best mileage so far. No modification on engine or whatever. I use copper spark-plug and I got only 9-10 km/L.

Did you go with Trifecta Performance for your tune?

I've been having a problem with my car smelling like rotten eggs when I blast through gears due to bad gas (lol) stinking up the cat. Switched to 93 octane, and no stinkiness! And I did notice with the gas I was using, coupled with the cold weather, my scanguage avg MPG dropped by 1.2

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