Does 91 Octane Gasoline Contain Ethanol?

I have! I actually saw a slight dip in miles per gallon when I switched to 91 octane with ethanol. I was surprised!

For me, ethanol blends seemed to cause more engine knocking. I switched to a non-ethanol gas for peace of mind.

That sounds like a good idea! I wonder how many people are aware of the potential impacts of ethanol on their engines.

I think it’s definitely something to consider. Ethanol can attract moisture, which might lead to long-term engine issues.

Exactly! My friend had to clean her fuel lines because of that issue. Ethanol can be a double-edged sword for fuel efficiency.

I’ve found ethanol boosts octane, but its impact on fuel efficiency does vary by vehicle type.

That’s true! I drive a turbocharged car and I’ve noticed it runs smoother with the higher octane but whether it’s worth it overall is still debatable.

Anyone know if there’s a significant price difference between ethanol and non-ethanol fuels at the pump?

In my area, non-ethanol gas is usually a bit more expensive, but I think it’s worth it for the potential engine benefits.

That’s good to know! I might give it a try. Anyone with older cars had experiences with ethanol?

Older cars can definitely struggle with ethanol. My uncle had issues with gaskets because of it. Just a heads up!

Good to know! Maybe I should avoid ethanol for my classic car.

And remember, not all vehicles are the same! Maintaining engine health can be a delicate balance—it’s like a fuel relationship.

Yes, 91 octane gasoline can contain ethanol, but the amount varies by region. In some places, you might find fuel with up to 10% ethanol, while in others, it may be ethanol-free. It’s best to check your local regulations or ask your gas station directly.

That’s good to know! I wasn’t sure if the ethanol levels would be higher in certain areas. What resources do you recommend for checking local fuel standards?

In my area, a quick visit to the state energy website provides information about ethanol in fuels. You can also check labels at the pump; they usually state the ethanol content.

That’s really helpful! I’ll definitely check that out. I’ve heard varying things about the difference between state regulations.

It’s interesting how ethanol content can shift so much by state. States with corn production often have higher ethanol blends. It makes me wonder how this affects engine performance.

That’s true! In regions with less corn production, you might find more pure gasoline. It’s all about local agriculture and politics, really.

I’ve heard that switching to ethanol-free gasoline can improve fuel efficiency for some vehicles. Has anyone experienced this? Just tossing it out there since we’re discussing ethanol.
