Fuel Requirements Based on Engine Type
However, sometimes people believe that using 91-octane gasoline (also referred to as premium gasoline) is a better way to go because it would improve your engine’s performance and lifespan. However, this is not true.
Using premium gasoline won´t hurt your Chevy Spark in any way. However, the Chevy Spark is not designed to derive any benefits from premium gasoline. For this reason, you will only pay more instead of getting actual use from premium gasoline. For this reason, it´s recommended you opt for 87-octane gasoline at all times.

What Type of Gasoline Can A Chevy Spark Take?
Reformulated Gasoline
Gasoline/Oxygenated Blends or E-85
We also have to discuss the use of oxygenated blends of gasoline. These types of gasoline contain oxygenates, typically in the form of ethanol or methanol, which are mixed into regular gasoline. These oxygenates are generally made from bio-sources meaning they burn cleaner and are cheaper to make.
However, the use of methanol and ethanol in the Chevy Spark is strictly regulated. Methanol is strictly forbidden to use in all generations of the Chevy Spark, and doing so will result in corrosion to the engine and fuel system that´s not covered by the warranty.
On the other hand, ethanol is safe to use in all generations of the Chevy Spark up to 15%. For this reason, E10 (10% ethanol) and E15 (15% ethanol) are safe to use. However, E30, E50, and E85 (also referred to as flex-fuel) are not safe to use and will damage the engine.
Addition of Cleaning Agents
(Do no use) Fuel with any amount of methanol, methylal, ferrocene, and aniline. These fuels can corrode metal fuel system parts or damage plastic and rubber parts. (Also don´t use) Fuel containing metals such as methylcyclopentadienyl manganese tricarbonyl (MMT), which can damage the emissions control system and spark plugs.

If you don´t have access to TOP TIER gasoline, Chevy recommends that you add ACDelco Fuel
System Treatment Plus−Gasoline to the vehicle’s gasoline fuel tank at every oil change or 9.000 miles (15.000 kilometers), whichever occurs first. This will keep your engine free from deposits.
