I have a 74' 2L with Weber carbs. Does anyone use a gas system additive. I have read many articles about individual gas additive manufacturers, but I can't seem to get an opinion about adding or not adding one to my gas tank. I thought they might be helpful to cleaning the carb jets, ect. but I don't know if they are recommended- Thanks -Rolf

I have a similar setup and use Stabil to fight the effects of ethanol has on rubber carb parts. Plus I have a good filter before the pump and at the inlet to each carb. And if you don't know about these https://www.cbperformance.com/product-p/7557.htm check them out as they will save you annual idle jet maintenance.

Marine Stabil works very well with Stewart's Premium no ethanol

I buy it by the gallon and transfer it to one of their 32 oz bottles with the dosing cap that I keep in the frunk. |

IMHO most additives are snake oil.
Not counting some FI cleaners and storage additives like sta-bil. |

I’m sitting in a coffee shop waiting for 2 other local 914 owners. We are going twisty road hunting this morning. First stop, ethanol free gas pump. Usually find them near boat ramps.

BG fuel additives are a good product for cleaning the combustion chamber, but I don't know about dealing with the ethanol issue

I have a friend who has used Marvel Mystery Oil as a gas additive for 30 years and swears by it, on his non cat cars of course.

Like other's mentioned:
I use Stabil Marine stabilizer and try to run a bottle of Techron every few takes to keep things flowing. |

Probably the best option is to try to keep driving the car as today’s fuels are designed to be burned quickly and not stored. Since that’s not likely in the Midwest, I try to find ethanol- free fuel and use Marine Sta-Bil over the winter.
