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.
Lower octane is not lower tiered. Lower tiered is buying gas at Kroger or Costco vs Shell
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%.
