Welcome to the discussion of US Politics!
Rules:
- Post only links to articles, Title must fairly describe link contents. If your title differs from the site’s, it should only be to add context or be more descriptive. Do not post entire articles in the body or in the comments.
Links must be to the original source, not an aggregator like Google Amp, MSN, or Yahoo.
Example:
- Articles must be relevant to politics. Links must be to quality and original content. Articles should be worth reading. Clickbait, stub articles, and rehosted or stolen content are not allowed. Check your source for Reliability and Bias here.
- Be civil, No violations of TOS. It’s OK to say the subject of an article is behaving like a (pejorative, pejorative). It’s NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
- No memes, trolling, or low-effort comments. Reposts, misinformation, off-topic, trolling, or offensive. Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
- Vote based on comment quality, not agreement. This community aims to foster discussion; please reward people for putting effort into articulating their viewpoint, even if you disagree with it.
- No hate speech, slurs, celebrating death, advocating violence, or abusive language. This will result in a ban. Usernames containing racist, or inappropriate slurs will be banned without warning
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.
That's all the rules!

I'm a car girl, its mkind of my thing. Octane ratings aretgere to protect your engine, its a rating of how readily the gasoline ignites in the engine. The larger the number the harder to self ignite. Most cars use 85, the only time the higher octane 93 is needed is for cars with turbo or supercharging, or cars with higher compression ratios.
Just put whatever its rated for in it, going with a higher octane than what your car is rated for doesn't hurt a thing, but it also won't make your engine run better or anything.
As far as ethanol goes, modern cars ate fine with 10-20% ethanol in their gas. It will get worse mileage the higher the percentage of ethanol as it is not as energy dense as gasoline. The E85 stuff has a higher percentage of ethanol (85%) than is allowed in conventional gas and was introduced to try and lower gas prices (it's actually completely ineffective and ethanol for fuel is more energy intensive than just giving us straight gasoline but they have to prop up the corn industry somehow). Regular cars can't use E85 unless they are rated for it as the engine has to add more fuel to keep a close to stoichiometric ratio of fuel to air.
TLDR: Use whatever octane your car asks for, if you put a higher octane in it doesn't hurt, but it also doesn't add any benefit.
When it comes to ethanol regular cars can tolerate up to roughly 20% with only a reduction in fuel mileage as a result. E85 is only for cars rated to use it as they need a sensor to detect ethanol percentage and adjust fuel to air ratios accordingly.
