If you’re running a higher dose rate, stick to that one treatment and wait until the next oil change before adding anything else.
I wouldn’t overthink it. Just avoid doing more than two treatments within a single OCI.
Techron Dosing Opinion?

Isn't the Techron only in the premium fuel? I believe that's how it works at Shell.
Techron is in all fuel grades. One reason I like filling up there
Oh, I'm not. A couple of posts here is already more thought than I would have given using 2 bottles in 20 gallons and driving off.

But is it as strong of a dose in their 87 octane as it is in 93? As another example, Shell says that their V Power has the highest amount of detergents (and it’s 6x the required amount) but doesn’t say what they have in their 87. Costco on the other hand says that all grades have 5x the required detergents. So for those using only 87 octane it’s most likely that Costco actually has the strongest detergents availableTechron is in all fuel grades. One reason I like filling up there
I have read that Shell V-Power 93 has higher detergents versus Shell V-Power 87 or 89. Is there a way that Shell V-Power 93, 89, and 87 could be tested to see if the detergent level is the same or different between the 3 grades?

Maybe at some point the Motor Oil Geek will do a test like this
The Chevron website doesn't state that there are different doses between the grades. Only that their patent add pack is in each. I would have to assume that it's equal in every grade since they have access to their own products at bulk??
Genuinely asking here, do we know that PEA is included in the detergents advertised by others? I have not done any digging into the matter. Just curious if it's apples to apples comparing the 3 we have in discussion - Shell, Chevron, and Costco.
He does have a video out regarding Octane and wear/performance, but not on this subject.
The Exxon / Mobil gas stations around me have all been refreshed with this branding lately.
Digging into their info page reveals:
When you fill up at an Exxon™ or Mobil™ station, you can be confident you’re getting high quality gasoline every time. Available in three octane levels, our Synergy gasoline has been engineered to help clean up intake valves and improve gas mileage and performance.§§
- Fuel detergents 1, 2 and 3 – provide outstanding cleanliness in port fuel injection engines, and now in gasoline direct injection engines. Cleaner engine parts can lead to better gas mileage, engine protection and engine performance. Our detergent keeps your engine 3X cleaner for better gas mileage.‡ (Benefit available only in Synergy Supreme+™ premium gasoline)
- Friction modifier – the ingredient protects your engine by reducing wear and tear by 30%.‡‡ (Benefit available only in Synergy Supreme+ premium gasoline)
I used to hang out at a dealership mechanic with some friends who worked there (so I could use the lift), and when they convinced someone they needed a fuel treatment (with no evidence other than "we recommend it") they would pull the fuel pump fuse and hook up a can of off-the-shelf Techron fuel system cleaner directly to the fuel rail. They would use compressed air to provide fuel pressure through the can and then turn the car on and idle it until the car died from lack of fuel. As far as I know this is how all mechanics do fuel system treatments. The fact that they ran the car directly on the fuel treatment makes me wonder if it could possibly be of any use when it's diluted by a factor of 100 or more (10 gallons would be over 100:1 dilution for a 12 oz bottle).
Here's basically what the dealership used: https://www.amazon.com/Injector-Disassembly-Free-Injection-Pressure-Adjustment/dp/B0CGN1QCP2
Ever since that day I have never used fuel system cleaner for this reason, and if I ever have reason to suspect fuel system dirtiness ... I would buy a kit and do the same procedure as the dealer did.
What do you all think of that? I'm not some kind of subject matter expert here, I just want to know what all of your thoughts are on this. Sorry to hijack the thread

Unless there is more included where the "§§" is at the footer, this reads like there is no other reason to use anything other than the Supreme+ Premium.
Synergy Supreme+ Premium looks appealing if you can stomach the cost.
Of course they're not going to say "no, you don't need to buy our product" !
if it helps or means anything I have been using “double doses” on any new to me used vehicle or those vehicles in the family I take care of since about 2014 without any issue…I have cleared a few fuel sender (fuel gauge) issues on GM, Ford and Toyota vehicles by doing this…I wouldn’t worry at all about what you are attempting to do...
It does, it's a significant anecdote and I appreciate the feedback.
Fwiw, for some time all I use is TT 87 gas, but no Chevron, there are none here. That said, either way 'for me' wouldn't change or be a consideration in my ~5k mi. CFSC use.
. Hope so .
That's a pretty good assessment for 87 and what I gather from reading here. 87 Costco > 87 Shell > 87 Chevron
I remember reading somewhere here that all grades/octanes of Chevron have the same concentration of Techron, which IMO is one of the bigger drawbacks for them vs Shell/ExxonMobil. Hence, the behavior of this board's posters using 91/93 for cleaning, deposit prevention, and friction modifiers rather than the sole need for higher octane falls apart when it comes to Chevron.
So the advice to use 91/93 only if the engine needs it definitely holds for Chevron if all grades have same Techron %.

I believe there are 9 additives counting the QAQC marker …

I have always rounded up with Techron - like two bottles for up to 12 gallons each - in an 18 gallon fill. No issues …
I'm fairly confident it does and would be surprised if it didn't. Would be pretty ****ing for their flagship product and overall brand image if it didn't.
What I'd really like to see is an 87 and 93 octane detergent comparison across brands (ExxonMobil, 76, Gulf, Chevron, Shell, bp, P66, Conoco, Sinclair, Sunoco, QT) repeated multiple times.
