Just curious if anyone has experience using Seafoam specifically in their C43 gas tank, or any similar fuel stabilizers for winter storage and keeping fuel fresh. Not sure if Mercedes has an "approved" product for this. Cheers.

I used it in older cars (91 Miata) and newer cars (07 RS4) I honestly do not think it makes a real difference in newer automobiles. Just my opinion.

As long as it'll keep the fuel fresh and not have any negative effects, I can't imagine it would be figured I'd put it out there to the community. I know some claim it's snake oil, I won't be worried about its deposit cleaning claims with a new engine etc.

I've been adding Sta-Bil 360 performance to my tank each time I fill up. I don't drive much and only need gas about every 8-10 weeks.

Stabil or similar products really do keep the gas from breaking down and gumming up. It'll be a lot more expensive to clean out the tank, lines and injectors. If you don't drive enough to use up the gas in a month or two I'd use it.

If you are in the US, look up Fuel Direct as they have a fuel enhancer that will keep your fuel good up to 6 months.
