Comparing 87- vs. 88-octane gasoline

Using Higher-Octane Gasoline in Your Subaru: Weighing the Benefits and Drawbacks.

If you're considering using 88-octane gasoline in your Subaru, think twice. While most modern cars can handle higher-octane fuel without issues, your car's engine may not be designed for it.

For instance, if you have a 2.5-liter engine, you're advised to use only 10 percent ethanol gasoline, according to the manufacturer's guidelines. Using higher-octane fuel in such cases could lead to reduced fuel efficiency.

In reality, Subaru models are capable of using reformulated gasoline with up to 15 percent ethanol without any major issues. However, when trying E-15, you may notice a slight decrease in fuel economy. This is due to the higher octane level which can make your car's engine less efficient.

On the other hand, there are cases where using high-octane gasoline could be beneficial for performance. However, it ultimately comes down to the specific requirements of your vehicle and how you use it. Always follow the manufacturer's recommendations when it comes to fuel type.

um so i was driving my friend's subaru the other day and we were talking about gas prices and then we saw this article about using higher-octane gas in them cars lol what do people think is more important anyway fuel efficiency or having that extra oomph in their engine?

I'm not sure if I'd bother with the higher-octane gas in my Subaru . I mean, yeah, it might give me a slight performance boost, but is it really worth the extra cash? My friend got his hands on some E-15 and said he barely noticed the difference in fuel economy . And honestly, if my car's not even designed for that much ethanol, why bother with the higher-octane stuff? I'd rather just stick to what my manufacturer recommends . Plus, using high-octane gas might void my warranty or something... that'd be a major bummer

I'm like "what's up with this octane thingy?" I mean, I've heard of using higher-octane gas in some cars, but my Subaru doesn't require that much... right? So if you're gonna use 88-octane gasoline, is it really worth the risk of messing with your fuel efficiency? And what's up with the E-15 vs regular ethanol stuff? I've seen some people say using E-15 can be better for performance, but isn't that just a myth? Can someone please tell me how to know which octane is best for my Subaru?

omg u gotta read this!!! so like i was reading about using 88-octane gas in ur subaru & honestly i thought idc, but then it got me thinking... i have a friend who drives a subaru with a lot of modifications & he swears by the high-octane fuel ! but then again, my cuz has a subaru too & she says its not that big of a deal, but uses the regular gas anyway . idk, maybe im just overthinking it?

I don’t usually comment but I had a buddy who upgraded his Forester to E-15 and noticed a pretty sweet boost in performance , at least until he hit highway speeds then it kinda felt like normal gas again. I don’t know if that’s typical for everyone though? Also, have you guys seen the prices of high-octane gas lately? Like, who needs that extra $1 per gallon?

I'm so confused about this whole high-octane thing . I just saw a post saying most modern cars can handle it without issues, but then I read that some engines might not be designed for it and that can affect fuel efficiency? Like, what's the point of having a sporty car if you're gonna lose power or something? On the other hand, I've heard good things about using high-octane gasoline when your engine needs it. It's like having a cheat code for your car . But seriously, shouldn't manufacturers just give us clear guidelines on what fuel to use so we don't end up wasting our money or messing with our engines?

I feel like this news is trying to tell us something deeper than just whether we should use high-octane gas in our Subaru . It's like, are we really listening to what our cars need? We're always looking for ways to squeeze out more performance, but sometimes it's the simple things that matter - knowing our limits and respecting them.

And then there's the 10-15% ethanol thing... it's like life itself, isn't it? A delicate balance between what we think we want (more power) and what we really need (efficiency). It's easy to get caught up in the hype of higher-octane fuel, but at the end of the day, it's all about understanding our own engines... I mean, our own limitations.

I'm like "what's the point of having a sweet, turbocharged Subaru if I'm just gonna waste gas"? I mean, I get that high-octane fuel can be beneficial for performance, but is it really worth it? Like, I'm driving around, trying to shave off a few seconds from my commute time, and then I realize I've just blown through an extra $10 on gas because of some fancy-pants octane level . And don't even get me started on the whole ethanol thing - 15% E-15 is fine, but what's with all the confusion around here? Can we just stick to one fuel type already?!

 

[CyberDrift]

using high octane gas in your subaru might not be as good as u think... my cousin has a 3.6l engine and he tried e-15 once and his fuel economy went down like 20% what's the point of using higher octane if it just gonna make ur car less efficient? plus, most manufacturers dont even recommend it for their models... might as well stick to the 10% ethanol gas

so i was reading about this and i think people should check their subs manual first before switching to 88-octane lol its like they say, better safe than sorry! but at the same time if you do need high octane its def worth a try, my friend just got his sub wrx upgraded with those bad boy performance chips and now its flying

I'm so done with all these complicated gas types ! Can't we just stick to regular ol' gasoline? I mean, my Subaru can handle a mix of 10% ethanol without any issues, and I don't see why I need the fancy high-octane stuff just because some car guy says so . I've seen people get better performance with it, but isn't that just going to be negated by the fact that they drive more aggressively? And what's up with all these different numbers - 10%, 15% ethanol... can't we just use 1% and call it a day?
