Should I use a fuel system additive? (2017 Porsche 911 991.2 Carrera C2S)

[Tier1Terrier]

Hi - I'm trying to figure out whether or not I should be adding Fuel Additive to my system. My car has relatively low miles (or when should I use it? What benefits are seen or are expected to be seen in the short and long term? Is there a downside in using fuel system additives? Techron seems to be the most popular/recommended but that doesn't mean it's the best. As far as maintenance on my car is concerned, I'm not looking for the least costly effective option. Just the best option (within reason). Any help would be appreciated. Thanks in advance!

Redline SI-1 is known to have the highest concentration of PEA per bottle, more than Chevron Techron

The first question I would ask is...where do you buy your gas from? Is it from someone like: Chevron, Shell, Union 76, etc., or any of the other Top Tier brands? If so, I don't know that you need any additives.

I use Berryman B-12 ("The good thing about Berryman’s product is that it’s solvent based whereas most other cleaners are detergent based."- https://bit.ly/33cbdFN) and sometimes Techron. I think they're both great products and might keep the fuel system squeaky clean with no side effects.

I'd say that if you're consistently using a top-tier brand from a station with high fuel turnover, you don't need it.

Where do you see that in print?

totally useless unless using fuel you shouldn't be using in a modern Porsche in the first place

Unless there is a specific issue you have that you are trying to solve, it's a waste of money. And even then, half of the stuff out there seems to be snake oil.

The MSDS has an approximate amount. Not sure if the formula has changed though.

Chevron says 25-35% by weight of some item protected as a trade secret and 1-5% another trade secret. I'd link it directly, but the percentages are on the second page.

Hmmm. Not quite the responses I was expecting but encouraging at the same time. I pretty much use only major brands of gasoline from gas stations like Chevron, BP, Exxon, Shell, Mobil, etc. From the sounds of the responses, there doesn't seem to be a need for additives if filling up at places like these... Or am I misunderstanding? Thank you all for your responses!

Not likely you'll need it.

It certainly won't hurt anything.

Running Techron, etc. the tank before an oil change is pretty standard "Porsche guy" fare.

I do the same with SL-1 on my BMWs.
