    Republicans vote to dilute gas as prices rise above $4.50

  • Good news, you're not fucked. Your car has been running on roughly 10-15% ethanol its entire life. If you havnt had problems yet, you likely won't. Unless they go full stupid and put an absurd amount in of ethanol in, then it won't effect most cars on the road today.

  • The main problem with ethanol in rubber fuel lines is that ethanol causes hardening and flaking of the rubber. Long before it ever gets bad enough to leak the little flakes of hardened rubber detatch from the inside of the line and travel down to fuel pumps, injectors, and carburators. Where they clog up all the small metered orifices that regulate the amount of fuel the engine is getting. This can lead to the car just not running or running poorly, to the internal components of the engine breaking or seizing, thus trashing the whole engine.

  • 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.

  • So you swapped out a few pairs of NOS parts on a couple classics. I worked as an engineer for akebono, one of the biggest brake manufacturers in the world. Almost every European and American manufacturer ditched asbestos around 1990. Some imported "value" pads may contain asbestos, and some classic cars are still gonna have asbestos pads. But the vast majority of cars on the road do not.

  • Asbestos isn't used in brake pads anymore, we've gone to organo metallic mixtures. So mostly carbon with some iron, manganese, and nickel thrown in.

  • That article says you can't import a byd unless its a subcompact that you license as a low-speed vehicle. Meaning it can't go over 35mph, so basically a golfcart.

  • Where do people search for used cars?

    Jump

  • FB marketplace or a classifieds site is where you will find the best deals, it's the only reason I still have an account with meta. It's almost always a better deal for both parties buying and selling person to person. Most people will be more honest about the condition of the car than any used dealers and they will also make more selling it directly than trading in or selling to a dealer. Buyers also save by cutting out the middle men. I'm into cars as a hobby so I'm fairly constantly buying and selling them, marketplace is where I do almost all of my transactions ever since Craigslist died.

  • The video itself is fairly hilarious considering he posted it himself. I honestly thought it was an ai video made to make him look bad/troll him at first. From him stumbling over the blocks, to the babg like squeaks and grunts he makes while doing it, he comes off as soft as a wet dog turd.

  • TIL for at last 15 years US government has been able to implant hardware into USB cables to turn them into hacking devices with wireless capability.

  • There are a ton of different payloads that can be run on these, for everything from simple keylogging, to root access, to network backdoors. I've only recently gotten into pentesting but with something like this there's no real limit to the damage that could be done with only a few seconds of physical access.

  • Trump threatens to shut down US government unless all trans health care is banned

    Jump

  • If passed, this would effectively ban trans healthcare. It would cut funding to any hospital or medical facility that provides gender affirming care. That means only private practices would be able to offer gender affirming care, and most of them would probably have to stop providing it. If they continued to, they would be ineligible to receive payment from medicare or medicaid for any other patients they see, not just the trans ones. The administration is talking about labeling all trans people as terrorists, why would you think they wouldn't ban trans healthcare with a smile on their shitty faces?

  • Question for the mechanics of Lemmy; what is the most likely problem?

  • Take both the battery terminals off, if there are crusty white or blue gunk on them you can use a little vinegar to clean it off. Clean the contacting parts of both terminals and where they connect to the battery with a wire brush till the metal looks at least vaguely shiny. Put the terminals back on and tighten them down with a wrench, if its an american car its usually a 1/2" if its an import its almost certainly a 10mm. If it doesn't work after that try jumping it again, if it still doesn't work its probably the starter or starter solenoid. You can try tapping on the starter solenoid with a hammer to unstick it as a temporary fix to get you going, but if you have to do that then it needs replaced sooner rather than later anyways.
