No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Context: I drive a 15+ year old SUV, and I am no longer in the position to just replace everything should anything bad happen. So sadly I will have to buy a newer car at some point. Hopefully not anytime soon 🀞🏼🀞🏼 But, I noticed when shopping with other people that newer cars sound weird. My knowledge of car troubleshooting is little more than sounds good/sounds bad, looks good/looks bad, smells good/smells bad, feels good/feels bad.

So, how are newer cars supposed to sound?

Depends on the car. If you've heard a 4 cylinder you've heard most of them. GDI engines have loud ticking fuel injectors at idle, this is normal, they're squeezing 600-2000 PSI of fuel pressure into the combustion chamber. Unfortunately, while a lot of modern cars have 4 cylinder turbos now, they are almost all smol turbos that spool at 2000 and run out of breath past 4000. They also don't make any cool turbo noises.

Engine will turn itself off when you come to a stop and it's warmed up. Don't worry, EV motor will get you going while the engine restarts. Lots of stop-start engines will start up as soon as you let off the brake pedal and be good to go by the time you move your foot over to the gas.

Also, engine may stay off for a bit depending on your driving mode and speeds. This is good, especially with a PHEV (Plug-in Hybrid Electric Vehicle), which has a small "for around town" battery it can drive on. Saves you in gas to charge it on the wall for those <40-mile grocery runs. Can also save you a gallon or two on longer trips by running on battery for a few before firing up the engine.

A lot of modern cars also play fake engine noises through the speakers so people who are allergic to the sound of a quiet car can pretend they have a V8 under the hood.

If you want a car that still has an angry growl but is good on gas, get a Subaru. Still a very "personality" car in this day and age, even with a CVT and a hybrid drive system. She makes lots of noises and demands your regular maintenance care (on-time oil and transmission fluid changes, regular oil level checks and topoffs if needed), but will last a long, long time if you do.

On Subaru and CVTs, I hate most modern automatic transmissions due to the rough shift and indecision but the Subaru CVT ain't bad at all.
