I’ve noticed sometimes that there’s some half-baked videos or blogs or whatever that purport this or that frugal trick, but if you look at the time or math, it’s not actually frugal for you.
What are some examples of that you’ve come across? The things that “aren’t worth it”?
For me it’s couponing. (Although I haven’t heard people talk about it recently–has it fallen out of “style”, or have businesses caught up to the loopholes folks used to exploit?)
Lower octane gas definitely gives you less power. The owner’s manual for my car gives two different horsepower ratings for different octane gasoline.
Probably a forced induction engine. Normal NA it makes no difference as long as it’s not a high compression engine. Octane rating is how much heat and pressure the gas can handle before auto igniting. So higher octane means an engine with a turbo can run higher boost on higher octane which makes more power. It’s a waste of money for most people to buy more expensive fuel. Though some fuel can be just shit and full of water at those sketchy stations.
That sounds right, my car is a turbo charged 4 cylinder. TIL, thank you!
It can still be optional to run higher octane. Older Volvo 5 cylinders could run 87 with no problem because they only ran 9lbs of boost (only certain models). Most modern turboed engines usually can optionally run more boost if you put in higher octane. The issue is they rely on detection of early detonation when running worse fuel. Which scares me because of it fails engine goes boom very fast.
Use the octane that is recommended for your vehicle.
Lower octane is not lower tiered. Lower tiered is buying gas at Kroger or Costco vs Shell
Ironically Costco is a certified Top Tier brand.

That’s interesting to know.
Project Farm did a scientific comparison and while the higher octane fuel does give a bit more power and efficiency it doesn’t generally result in much difference. Like less than 5%.
