what fuel system cleaner

So? they do change parameters, but it does not mean there is no difference. i have noticed multiple cars i had preformed better with 93 gas vs 87, regardless of their age. orbital is absolutely correct, it is not a placebo. some even show clear difference on dyno tests.

In the eighties, Formula1 teams had engineers who did nothing but develop & test gas additives to get a bigger bang per revolution.
Octane could not be changed, that was a huge regulation.

Things were learned.

In the 90s' I went full OCD on mpg with high octane vs regular. The high octane was better mpg and that offset the cost diff. Vehicle ran better also.
This is when I started using Chevron gas up in the northwest.

Thinking TurboD is interested in more specificity regarding performance enhancement; numbers compared, percentage increase, etc.

I used Seafoam maybe 5 times on an ‘86 Nissan pickup because idle is not inclined to stay lit; can’t say it helped but it did not hurt. It may have a tiny chunk of something partially obstructing the little port that supplies fuel for idle(?)

When we first got our Tacoma, I spoke with a retired mechanic friend about how Toyota said to use an octane level that is slightly higher than what is available here for regular gasoline. He said our higher altitude (5000+ feet) needs to have lower octane to lessen the chance of premature detonation (I think he said it that way) but my wife for years used the mid grade octane in her Toyota van with no problem years ago.

Before giving away our cheapo generator that came with the house, I used premium gas in it, thinking ethanol would not be in it. Seemed to start easier and run sufficiently. Never tried Seafoam in it though.

I use BP gasoline. Don't know what they put in it but I get a few more miles between fill ups. A rarely go below 1/4 tank but I don't know if that matters because the siphon hose it at the bottom of the tank anyway.

In my rarely drive it cars I use Lucus marine grade stabilizer at a triple dose. Same with my lawn equipment.

I put the Chevron cleaner in each car once a year.
When I found out that GM private lableled it, I settled on it since all my vehicles are Chevys.
