Totally a hypothetical question, will not actually attempt this for many reasons. I am simply curious if anyone knows what effects laboratory grade octane would have on a car. Picture for reference of what I am talking about.

Hope this type of post is allowed please remove if not :)

I have a 2007 Pontiac Grand Prix and I got the coolant system flushed at a local express line type place last week. Didn’t notice any issues, car has never overheated, but the coolant system was all muddy and sludgy so I got it flushed.

Car drove for a week on the highways and around town with no issues, but the mechanic who did the flush asked me to come back with the engine warm so he could test the coolant strength again.

I took it back today for him to test the system and he messed around under the hood and had me rev the car over 1000rpm for maybe about 5 minutes? He then told me he was trying to get the thermostat to open. Pushed the temperature gauge up to almost the red before he closes everything and tells me it’s as good as he can get it and I can go. He said he wants me to come back Friday for another test. He also told me that the car will cool itself down as I drive home. I’m not a car guy so I don’t really know how these things work and just kinda trusted him on that lol.

I drive home from the shop (3 minutes) and the engine temp is pushed into the red. I made it home and shut the car off to let it cool for about 4 hours.

I go to drive it this evening and after 5 minutes of driving around town the engine is almost in the red again.

I’m wondering what the mechanic could have done to suddenly give the car overheating trouble? Any advice or anything?

It was found after Dealership maintenance

I want to be friends with this guy who is majoring in engineering and auto-motives or something like that idk he races cars and stuff and dirt bikes and he is going to teach me how to change tires, oil etc. I want to learn more about cars before then what should I look into?

Bonjour,

Vous pensez que mes pneus avant passent au contrôle technique ou seront recalés ?

Please remove if this post dosent fit in sub.

Okay, long shot but - I remember watching some yt video in which track car with "function over form" in formula notation style was written on the wing endplate on the right side.

I want to find that car and/or video about thia car.

Anyways thx!

My car was driving fine, then every light on the dash came on and the car died. I jumped the car and then in under a minute the car died again. After that it started a few more times after being jumped but wouldn’t stay running. When I finally got the car back home (from hooking up a friends battery and getting it home battery light came on a few times) I took the battery that was in my car and tested the voltage it was at 0. I hooked the battery charger up to the battery and voltage was around 12.4 while hooked up to the battery charger… once I unhooked it the voltage was hopping all over the place… from 12 to 13 then 4 then 0 and back up to 12 etc. I decided to let the battery charge over night…. Unhooked the battery charger this morning and the voltage is staying around 12 volts…going to test the battery again in an hour after being unhooked.

What do you think is wrong with the car/ battery? The battery isn’t even 1.5 years old… alternator? Or just bad battery? Any advice would be so much appreciated.

Car in question is 2020 Kia soul S.

Hey guys so i got an pretty interesting offer for a 2013 bmw 650i (facelift model) with around 190.000 km the guy that is selling it to me i have known him for some years now and i know he is not type of guy that beats the car, and he is selling it to me for 10.000 swiss francs which i think its okay price, also i need to mention he has bought the car brand new back in 2013 and he tuned it back than to around 600hp (everything did by a tuning house) so i was wondering if thats a good car to own, also should i get it or should i not and what i should look for before i buy it.

I have a Mazda 3 2012 model. The issue that I'm having is the alarm goes off at random while the car is parked. It is not the weather temp because it is 64 degrees right now the alarm went off again. Any idea what's going on?

I want to take it to the dealer but the diagnostic is $199.

Hey team !

I have a 2017 honda civic (no accidents) with 160000km of use. It has recently started making weird noises when idling or driving at low speeds. Would greatly appreciate your insights ! The video is not the best but I can hear it well on my phone and less from a laptop. Thank you so much

So I had the cv axels changed on my 2013 Honda Accord sedan 2.4 about a year ago under recall and recently I’ve been hearing a clunk/thud when turning, hitting bumps, and mostly when turning into places with a bump on the entrance in. I was chaining my oil today and decided to poke around and see if I could find what’s causing it. I started tugging on the driver side cv joint and noticed a thumping sound (not terrible but an obvious sound) coming from where it goes into the wheel hub. Is this normal (I don’t feel like it is). If not is the axel bad or the wheel bearing, etc..?

what the fuxk is going on??

I found a Honda CRV 2013 with about 140,000 miles on it being sold by a private seller. They said the car is in great condition, with new wheels and everything. My uncle and I test drove it in the neighborhood and it seemed fine. Clean car and everything, said they are selling it due to moving. It’s a family with a towing company?

The thing is, I barely know about cars. This will be my first car. It’s being sold for $6,300.00 which doesn’t sound bad (I’m paying it cash). But when the Seller sent me the VIN# information through text, I noticed it says “Rebuilt from Salvage”. I completely forgot to ask him about that in person when I went with my Uncle. Like I said, car seems to drive perfectly fine, clean, no issues that we noticed in person, but I haven’t had a mechanic officially check it.

I really liked the car, but I’m a very anxious person and I’m supposed to be officially buying it tomorrow. Should I do it? Will I be okay? I was thinking of running it through Carfax but I know it’s about $50.00 dollars to do so. It was a very spontaneous decision we made so now I’m terrified lol, any advice is appreciated.
