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?)

That article is talking about the quality of gas and not regular vs premium. Quality is very important and “top tier” is a rating that sets a minimum quantity of detergents and max water content. So it’s good to try and find that top tier sticker on the pump but it’s still marketing. Top tier is a company AFAIK that sells the label after verifying the gas meets their requirements. All gas comes from the same place in your area so the top tier thing is even more questionable.
Also that article mentioned regular vs premium and says not to bother using premium if your vehicle doesn’t require it.
