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?)
Searching for the cheapest gas station. Too much time and gas.

In Australia there are apps that show cheapest prices near you, so at least there’s not too much time and effort involved.
Ah good. Sorry. I’m traumatized by parents driving obsessively around for hours looking for best prices on things…obviously there are better ways now.
There was a trick with the Caltex app where you can do a price lock and then get the fuel from any other Caltex station
What people would do is find the cheapest fuel in the country, use a fake GPS app to make the app think you are close by and lock in the price, then go to their local servo and use the locked in price. Saving 15/20c per litre.
Growing up, that was my mom. She’d circle the parking lot for 15 minutes searching for the perfect spot, then if she saw someone come out to their car would post up right behind them for an uncomfortably long time waiting for them to leave.
I used to hate it so much
We have gasbuddy in the USA. You don’t even need their app (though they have one).
Yep my wife will drive 8 miles to Costco…if you’re going anyway it might be fine. But 16 miles at 22 mpg with $4 gas means it costs $2.80 drive there and back. Saving 8 cents a gallon would be $1.28 in a 16 gallon tank.
I buy gas at the station 1/4 mile from our house…I don’t look at the price. It’s always reasonable.
Cheap gas ain’t good gas anyway. You end up paying for it later in lost fuel efficiency.
You can buy Top Tier now, or you can buy a bottle of polyetheramine later.
Edit to add: this is about the type and quantity of detergent pack, not about the octane/grade. Brands are required to have 2x the EPA mandated minimum detergent in all grades and at all locations to carry the Top Tier logo.
Costco carries it. So the generalization of cheap = bad does not always hold. But it very often will.
Can you cite any evidence that lower tier gas gives worse MPG?
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.
Exactly. I tried top tier gas (91 octane) and noticed no difference in gas mileage. I live at high elevation and have the option of 85 octane and do notice the engine rides a little rougher than with 87, but fuel economy is pretty much the same (like within 2%?).
Just get whatever your car’s manual states. Some cars need higher octane, most don’t.
You guys are confusing top tier gas vs higher octane. Or this thread has just been interchanging them and not being consistent. Two terms are being used. Top tiered as name brand vs higher octane. Both discussions are happening at the same time.
I mean the octane tiers at the pump, or what is usually marketed as regular, premium, etc. There are at least two other terms used to describe gas tiers:
AFAIK, all three terms are independent of each other, so you can have tier 3 gas with or without detergents, in any octane tier you need.
I agree but in this thread people are interchanging high octane vs top tier.
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%.

In the US, there aren’t that many refineries. No matter what gas station you go to, your gas is most likely coming from the same closest refinery. The only exceptions here are a few of the name brands, and even then it may not be true, they have their detergent blended too it.
The detergent is the biggest difference. Top Tier brands are guaranteed to have 2x the EPA mandated minimum detergent levels.
If you aren’t getting more detergent at the pump, you end up having to pour it in later to restore performance.
