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?)
Oh shoot thought you replied to my comment, can’t trace lines well I guess.
I was looking into it a bit and the whole thing seems scummy. Yes it sets requirements that are hand wavey good for your engine. But it also seems to force gas stations into using only a handful of vendors so they get that sticker. It’s endorsed by the big automakers but they also endorse the regular fuel standards. I wonder who is paying top tier LLC for the sticker and all their marketing?
The stations that carry it tend to only carry one brand to begin with. The owner of that brand is generally the one that pays, as they have to submit for testing at their own expense.
It’s not always more expensive. All Costco gas is Top Tier, for instance.
They require the brand to use the 2x detergent level for every grade, at every location, to display the Top Tier logo.
I go through a tank of gas every 1-2 days. When I don’t fill with Top Tier, my fuel economy goes down on that tank. When I consistently don’t fill with Top Tier, my fuel economy goes down even on my next tank of Top Tier. That’s when it’s time to throw in a bottle of polyetheramine (Techron, Redline, Gumout Regane, etc.) to clean things up.
DI engines unfortunately require deeper, periodic cleaning, as the additive will not reach the valves. But I do not have a DI engine, so the detergent makes a significant difference.
It particularly makes a difference in how often I have to (or do not have to) replace lifters to keep them in spec. This engine has solid, non-adjustable lifters.
