Until us wankers start testing gasoline like engine oil, we will never know.
Is Shell Premium Considered Best Cleaning Gasoline?

"The additive is not listed on the EPA's official register of certified detergent additives, though it is registered with the EPA under the name Kirkland Signature Clean Power." The formulation is exclusive (owned by) Costco.
It’s not on the list. But Lubrizol 9888/9888C/9888H are on the list.

Yes .v power is ,5-6 ti.es minimal m EPA Detergency. Here stamford CT, last week cheapest v power was $3.67 gallon.tnier 87 only twice detedgency $2.77 gallon.
Citgo, triclean..cleans 44%-77% in all 3 grades..3 times Detergency. Per website.
Mobil is twice detergency..synergy only benefits in 93 octane,band here it's about $3.79 and up for it. Too much for what it's advertising.
Phillips 66 here 3.5 times Detergency..up to 5 tanks can clean engine up per website..in all 3 grades ..3.5 times detergent
$2.77 gallon reg.
Ide use v power only before oil change.as I use redline sl1 or gumout tegane full tank 200 miles before empty. Then like too hookup berryman intake combustion chamber cleaner via vacuum hose..v power should help clean piston tops.
Might do another tank v power after.but after that I use Phillips 66.
At $3.77 gallon v power I am empty almost at 13 gallons. 18 gallon tank
$2.77 cost me $33-$34 fill.
$3.77 will be $10 more.not worth it to me

I’m cleaning up my ‘07 CRV I took over from my sister in law that has some pretty funky piston tops. I’ve been running Shell V-Power 93 for the last couple months and will take some follow up boroscope pics soon. These below are from when I first got the car.
Thanks, looking forward to seeing em. Any other fuel system cleaner usage (Techron, SI-1, Regane, BG44K)?
I can't say Shell premium is "the best", but what I can say is my 2025 Pilot and Shell premium get along with each other better than any other fuel. On our 1,200 miles' trip to the daughter's in Madison on Thursday, I started with Shell premium. Just as leaving Texas into Oklahoma, we stopped for a bio-break at a Quik Trip (TT certified) and I decided to top off with their premium, which was actually about 5/8 of a tank. Next stop was a Conoco station (TT certified) just before the Kansas Turnpike. Before long, when going up the rolling hills in Kansas, I started noticing a slight vibration similar to having a rear tire out of balance. It could be felt in the steering wheel, seat, etc. The drive mode was selected to Tow, so VCM was not engaging. Filled up with Shell premium (non-ethanol) on the other side of Kansas City and all vibrations stopped almost immediately.
Had I been driving around town, I'd never have noticed these subtle vibrations, but cruising along for hours on end, you notice things.
I am absolutely convinced Shell premium is the best fuel for my Pilot. Others may have a different experience. Like the engine oils we choose, what works great for one person in their vehicle may completely fail in a different person's application.

Yes on the Mitsubishi
You are absolutely spot on....
Its definitely a big difference between between 87 n 93 but I go cheap with 711 gas
yeah with prices lately I’ve had to drop back down to 87 boooo. the only thing I dislike about Shell is I cannot find any supporting documentation that their 5-6x stronger detergent package is present in their standard and mid grades. only the 93 gets the “V Power Nitro+” branding which is potentially a different thing altogether from the detergents.
My second choice is Exxon/Mobil stations which supposedly have the next strongest add pack with their “Synergy” branding. I also put Chevron with the og Techron on the same level.
Third tier would be BP/Amoco with “Invigorate” and others like Citgo, Phillips, Valero, Marathon

That’s why if you use 87 your best bet is likely to be Costco because they have 5x the required amount of detergents in both grades of their fuel.
Other than them I’m not sure if any other brand has that much detergent in their 87 octane.
Never ask a question that contains the word " best " ..
This BITOG post has a discussion between the member and Shell related to same/different add packs and concentrations.
Question about Shell V Power. My understanding is that most gas stations have pumps that mix premium and regular fuel at the pump to create a mid-octane fuel. Does anyone know if that's the case with Shell?
If so, does that mean the mid-grade Shell likely has somewhere between regular and premium V power's level of detergents? Or does V Power add the detergents at the pump so they can keep it solely in the V power? Or do they have 3 different tanks of fuel in the ground?

My understanding is that all octane versions of a given company's gas brand uses the same detergent additive pack in the same quantity, regardless of what the marketing on the pump may have you believe. EDIT: Shell does vary the detergent on different octanes level. As I just discovered today.

That’s not what Shell says on their website

I have only seen 3 Chevron tanks break through the concrete:
3 octane levels at pumps - but they also sold diesel …
In my part of the country, most people who actually care what they are putting in their tank, think that Chevron has the best cleaning gas, followed closely by Shell and Costco. Chevron stations are everywhere here in Utah, and typically price their gas only slightly higher than other stations, where Shell is always priced noticeably higher than everyone else. That could have something to do with the local favored attitude to Chevron.
Shell has to be feeling the pressure of Costco advertising 5x, but at discount rates. Perhaps 6x is little more than justifying premium pricing?
Exactly my question. Is there a point of diminishing return, where just adding more does little to clean any better?

Maybe we need a how far is Costco thread - betting lots of folks are not that close? 45 miles for me - pumps = Zoo …
Definitely a factor in selecting where you buy gas, but has no bearing on which gas cleans best. Having a few top performer choices does help in the convenience factor. For me, there are two Chevron stations within 3 miles of my home, and an Exxon within 2 miles. The nearest Costco is a 23 mile drive, so I only fill up when I'm in the area.Maybe we need a how far is Costco thread - betting lots of folks are not that close? 45 miles for me - pumps = Zoo …
Really, this discussion seems a little academic, as it seems the biggest difference in fuel cleaning is going to be between those stations that are not TT, those that are TT, and TT+.
