One of the more useful AI videos, even if it is scraped from the internet, including discussions on the forums here. The danger there is that it can include incorrect information because it just doesn't know right from wrong, so always double check the information.
For example, skip the fuel system additives if you have Top Tier fuel in your area.
Also, skip the anti-seize on the spark plugs.

Thanks Bill, all good stuff!
I also drain and fill the transfer case and rear differential when I change the trans fluid and filter every 30,000 miles. This video missed these important items.
I just checked my transfer case and rear diff fluid levels. At 17,000 miles BOTH were about 30% below full. These items are worth checking to be sure Mazda filled them correctly.....
I've become a fuel additive junkie after reviving my Cummins Diesel injectors with a fuel additive. It may not be necessary but I'm adding injector cleaner to my fuel at every oil change, 5K miles. I have a controversial additive I put in the fuel every fill up, to absorb water and improve combustion. In the diesel world most of us have our favorite "snake oil" additive. I've logged a difference in FE when using fuel additives. They more than pay for themselves.
Down the road, at 30K, I'll add 1/2 quart of HSS Stiction Eliminator. This stuff turned our 100k mile 08 Honda Accord around. It drove better than new. It got it's best fuel mileage after adding. This is another diesel thing folks do every 30,000 miles or so to clean the soot out of the piston rings. At 250,000 miles on the Cummins HSS Stiction Eliminator eliminated blow by and quieted the engine.
No anti-seize on my plugs either. I'm very careful how much I tighten. And never, never use an impact gun on any aluminum part. I use old school speed wrenches replacing plugs and anything else it will reach. After a dozen or so stripped aluminum threads over the years I changed my methods. So far, no more trouble...
Avoid idling whenever possible...

I have been wanting to attend an Additive Anonymous meeting. Is it Hotshot, Sta-Bil, or Heet? 
Sta-Bil small engine quick fix helped start my mini moto after it sat for 5+ months.

Additives Anonymous is a one fuel tank at a time program! And I can stop using fuel additives any time I want to! Really!!
Sta-Bil marine grade, best bang for the buck! Our turbo loves it...
I have another unmentionable banned from this forum. The moderators delete these posts. They deemed this subject might be dangerous. I discuss this on a Domestic forum. My Domestic loves it and when the time is right, the Mazda will get the same. I'll stop right there....

I can't stop. I had my first shot of ATF additive recently and it felt good. 
I think additives are more accepted on domestic and euro forums.
I respect the mods here and appreciate their work. Last night I wrote something redundant in a post and woke up this morning to a better structured sentence.

Looked it up on Amazon. They only have speeder handles with grip on the end, not the center part. This is for me to turn with both hands? There's also a T-handle wrench that I can see myself using.
The difference between marine and in-season seems to be the concentration (1 oz per 10-gallon v. 1 oz per 5-gallon). My order history shows that I have purchased the in-season once in 2022. Besides Lucas at each fill-up, I use Redline at each oil change.
Only been wrenching in the last 15 years and not familiar with all the tools out there.

I'm curious about this. It doesn't sound like anything that I, as a moderator, would delete or ban someone over. Usually we only resort to post deletions and warnings/bans if the discussion devolves into condescending language or personal insults, and spam of any kind. Even for stuff that's against forum rules, like political discussion, we try not to delete and instead just post a reminder.
Maybe it was just a one-off thing that another moderator might have mistaken for spam?

For my two domestics I rely on groups instead of forums for tips and advice. Didn't find much info about additives there. Can't think of any specific product or brand that would be considered dangerous. Are you cooking your own mixture?

We only "cook" our race fuel! Nitrometane ftw!For my two domestics I rely on groups instead of forums for tips and advice. Didn't find much info about additives there. Can't think of any specific product or brand that would be considered dangerous. Are you cooking your own mixture?
Some of us are using a refrigerant in our AC compressors that runs about 8 degrees cooler and 40% lower compressor pressure.
It's a cheap hydrocarbon. Our system holds about 15 ounces of refrigerant gas. Sorta of like peeing in the ocean when comparing the danger of gasoline and oil we carry. But others thought it was too dangerous for this forum.
We have the coldest and most fe AC, period.
I watched it twice before I posted it and I still can't understand how fuel additive will clean carbon off the intake valves in a direct-injection engine.
I know it will do a good job cleaning up the varnish coating that builds up in all the fuel components and I use a good quality one annually, but it never touched the valves!
I do occasionally take the revs up by gearing down to break up any carbon build up.
This Skyactiv wasn't designed to be a low speed commuter engine.
I knew a mechanic in the '60s who was an expert at fixing cars for elder drivers who only used their cars to make low speed trips to the grocery and complained of power loss.
He would take the car out behind the shop, hold the revs above 1500 and slowly pour a glass of water in to intake.
He claimed the shock of the water flashing into steam would break up all the carbon build up and restore the power.
It seemed to work.

That channel is the definition of AI slop. I should specify the first channel posted.

What the hell are you talking about??
Many channels have popped up like that are put together by AI to generate passive income. Most of the content is built by something like Google Gemini that you give it a topic and scrapes content made by others and random posts online and stitches them together. Often things are not correct. I'll just choose two from this video to address.
1st, you mentioned how you don't understand how gasoline additives will clean the valves in a GDI engine. You are correct. There are very few instances that Mazda will inject any fuel when the intake valves would be open even a small amount where fuel could touch the topside of the valves and those are generally only when transient events of going from Miller cycle to OTTO and the fuel injected is so small it wont even begin to do anything to a deposit on the valves. Let alone calling it the 'elephant in the room'.
2nd, telling you to change spark plugs before the recommended mileage, why replace a plug when it is perfectly serviceable?
This sort of content is very annoying and something I have to battle with daily in my profession.
