E85 Gas vs 87: What’s Best for My Chevy?

Questions and Support
1

Introduction

I’ve been doing some research on the differences between E85 ethanol fuel and 87-octane gasoline, especially in the context of my Chevrolet vehicle. I’m trying to figure out which one would be the most cost-effective and efficient for my car’s performance. With fuel prices fluctuating and the growing popularity of alternative fuels, I’m looking for insights from those who have experience with this!

Fuel Performance

From what I understand, E85 typically has a higher ethanol content, which means it can burn cleaner than 87-octane gasoline. However, I’ve heard that E85 might reduce fuel economy. For Chevy owners, does anyone have experience with how switching to E85 has affected their mileage? Is it worth it for those of us who want to optimize performance?

Cost Considerations

Additionally, I’ve seen E85 priced lower than 87 at some stations, but does that price difference hold true over the long run when considering fuel economy? If someone could provide a comparison of their fill-up experiences and any potential savings or drawbacks, it would be really helpful!

Compatibility with Chevrolet Models

Are there specific Chevrolet models that perform noticeably better with E85? I know many Chevys are designed to be flex-fuel, but has anyone switched from 87 to E85 and found outstanding performance or issues? I’d love to hear your thoughts about the compatibility and any modifications that need to be made for optimal performance.

Conclusion

If you have any insights, experiences, or data on this topic, please share! I want to make an informed decision for my next fill-up, and I’d appreciate any help on whether E85 or 87 is the better choice for my Chevy.

E85 has around 85% ethanol, which can lower fuel efficiency compared to regular 87 octane, which is about 10-15% less efficient in many cases. It’s important to check your Chevy’s compatibility too!

That’s an important point! I’ve heard that while E85 may lead to lower mileage, it’s typically cheaper than 87. Has anyone calculated cost per mile differences?

4

From what I’ve gathered, the cost per mile often ends up similar, if not better for E85, depending on local prices. Just remember that ethanol can also affect your fuel system long-term.

5

That’s true. My cousin had issues using E85 in his older Chevy, but newer models are more tolerant. What year is your Chevy?

6

I drive a 2019 model, and it runs great on E85! It’s just about getting used to the frequent fill-ups due to lower mileage. But hey, I like supporting renewable fuel sources!

7

True! But I think the environmental benefit is a great plus. It’s a toss-up for cost but worth considering the future impact!

8

I must admit, I’m skeptical about the real benefits. Isn’t it just marketing? What if E85 ends up costing you more since you fill up more often?

Haha, I get that! But for my Chevy, I’ve seen real savings in my fuel costs. Plus, we should support local corn farmers, right?

You gotta love a good local farmer support angle! Still, I wonder how many miles you actually get per gallon with E85. Anyone have that info?

11

Great question! In most cases, E85 delivers around 25% fewer miles per gallon than 87. Reflecting on that can help gauge whether the switch is worth it for you!

I think using E85 can actually improve performance in some Chevys, especially if they are flex-fuel vehicles. Higher octane usually means more power!

13

That’s true! Flex-fuel cars like the Chevy Impala or Malibu are designed for it. If your Chevy isn’t flex-fuel, you might face issues!

14

I’ve heard that E85 can lead to better engine tuning, but it may require modifications like upgraded fuel injectors. Is this correct?

Yes, you might need to adjust the tune because E85 has different combustion characteristics than 87. It burns cooler too!

16

But isn’t there a power loss when you switch to E85? I heard it can produce less energy per gallon compared to regular gas.

It’s true that you might get fewer miles per gallon, but the added power in some cases can make up for it if tuned correctly.

18

I’m considering switching to E85 for my '15 Chevy Silverado, but I read some owners have had mixed experiences. Supportive or painful? Haha!

19

Haha, great question! Many have had positive experiences with performance, while others note the maintenance can be tricky.

What about environmental impact? E85 is often touted as being better for the planet. Anyone confirm this?
