Does gas quality make a difference?
Anyone notice a difference in how their Fit runs depending on the quality of gas you buy? I notice my car idles smoother and gets better gas mileage on lower ethanol gas, usually from Esso.

Whenever this question of some version of this question get's asked?
You just get every opinion possible.
I don't really notice a tangible running difference between running higher octane, premium or just regular. The only caveat is that I pretty much always fill up at Top Tier gas stations.
So my personal opinion is "quality" gas may make a difference, but "grade" of gasoline? I don't notice much if any difference.

I run top tier gas unless I have discount points from the grocery store, which works out to be about every other fill up. I run 85 octane (I’m at high altitude) but may occasionally go with 87 octane I.e. mid-grade/89 octane most places on winter gas.
FWIW, 7-11 has sold top tier gas for decades. ...

Never noticed a difference with the Fit except with premium. Gave it more pep in it's step.
I honestly didn't always fill the Fit with Top Tier but with the veedub always fill up with TT. I go out of my way for it. 93 octane!!!!

Octane is knock prevention :}
Some sports fans think our cars need that to keep our spark plugs in place. premium does have some added kick.
Edit: its eccentric, but I run shell or chevron exclusively, unless on a road trip.

I have not noticed any changes between Speedway 87 (non TT) and Shell 87 (TT) for Summer gas here in New England. I wonder what Winter gas differences will bring now that refiners have to switch to a higher vapor pressure gas Nationwide by 15 September. It depends on where you live and what time of season...

Federal law prohibits gasoline with a Reid vapor pressure (RVP) greater than 9.0 pounds per square inch to be sold at retail stations from June 1 through September 15. (Geeky side note: RVP is not a traditional pressure reading. Under the American Society for Testing and Materials’ D323-99a standard, one part gasoline is submerged in a dual-chambered container with four parts air in a water bath at 100 degrees Fahrenheit. A gauge measures the resulting vapor pressure in the air chamber. Therefore, the RVP measures a gasoline’s vapor pressure at 100 degrees, not at ambient temperature.)
According to ExxonMobil, there are at least 14 unique types of summer-grade fuel sold nationwide. While the majority of states fill up with conventional 9.0-psi RVP gasoline, refiners must produce blends that are oxygenated, to reduce carbon monoxide; reformulated, in 17 states, to further reduce ozone and smog-forming toxins; for California only; and more. It gets trickier with ethanol. Since 97 percent of all gasoline sold contains ethanol—and, according to the American Petroleum Institute, ethanol blended up to 10 percent results in gasoline with a 10.0-psi RVP—the EPA counts such blends, called E10, as meeting the 9.0-psi standard. But many states, including the entire Northeastern seaboard from Delaware to Maine, don’t cut ethanol any slack. So gasoline refiners must be creative to reduce summer gas volatility, and creativity is expensive.

My mechanic friend says it doesn't matter, use the lowest grade gas to fill up the Fit. However, I stick to Shell, and I've used 93 octanes for a track day and "shenanigans," and I feel a difference. Albeit, slight.
