Even standard fuel injector performance will decrease with regular use of non-detergent gasoline. Running every other tank probably won’t cause an issue.
I guess folks just need to ask themselves if saving a nickel per gallon ($2 per 40gallons) is worth it. It reminds me of my wife who use to drive all the way across town to save a couple cents per gallon. It made sense in her mind until I showed her the math.

I’m pro detergents won’t run anything but a top tier fuel supplier. I’ve torn plenty of motors down and seen the difference between Kroger fuel and shell. That being said all my vehicles are diesel lol. Just the boat is gas powered but it only gets top tier
Side note though surprised no one has mentioned the crankcase recirculation system and how much cleaner a engine would be if one was to bypass it and install a catch can system

So how come I can put a stock truck
running 87 octane from the factory on a dyno......say a GM 5.3L and increase the timing and fuel tables with 93 octane and make more horsepower?
How did GM in 2014+ have the 5.3L make 355hp 383 ft lbs on 87, but when running 105 octane E85 it makes 380hp and 417 ft.lbs knowing GM increase the timing tables when the alcohol sensor reads 85% alcohol?

I just rolled 250k miles on all original drivetrain on a 2002 Sierra 4x4 5.3l, runs great, reliable and consumes nearly zero oil.
I just changed the oil for the 10th time.......I will let that sink in for a moment.
Amsoil since day 1.

tuning is one of the best ways to get more poop out of a motor without changing the octane or compression requirements.
the raptor 400 and 440 motors are identical. only difference is software. where is the extra hp/tq coming from the 440?
personal experience. in 2006 I drove my evo9 to oregon. car was filled with 91octane premium(recommended by mitsu). a guy named Jestr flew from Florida for a tuning session. strapped the evo to the dyno. base pull was 302hp/297tq. only opened the hood to cool the engine-no parts added and nothing mechanical changed. no changes to fuel or additives. 7 pulls and 30 minutes later. dyno reads 363hp/362tq. where did the extra 60hp/tq come from with no changes in octane or compression.
take a car tuned on 87, feed it 93, change nothing else and if you messed with the tune you will get more hp/tq out of it. messing with the timing and fuel delivery will net more power.
read this article and see that in Boise's case ALL fuel is coming from the same source whether it's ethanol/non-ethanol/top tier/discount. additives are added later. the couple stations that sold both mid grade ethanol and mid grade non-ethanol are getting them out of the same bulk tank of fuel.
interesting that I would bet a lunch spokane is operating the same way as some of your gas is coming through the same pipe from boise and some from billings thru a similar pipe/delivery system. betting money just like boise the additives/ethanol are put in once in the area.

had one in the evos. just don't let the emissions testing stations catch you primary goal was keeping the oil out of the intake tract. iirc I dumped a small amount each month. probably a 1/4qt each oil change.'06 Supra Launch 20SSV-gone but never forgotten

GM engines LS and LT should run a catch can, especially on a supercharged variant like the LSA, LS9, LT4 and LT5. The PCV systems are a little goofy.
I understand guys who are wrench savy, but regular joe would struggle with understanding the catch can maintenance.
I run one on my LSA and it keeps the intake tract clean.
