I can’t remember who recommended it, someone on the forum here, but Berryman’s B12 is the fuel system cleaner I use. I dump in half a can before filling up, probably once every 3k miles or so on both my cars. Use a bit of it to start my John Deere every spring too.

Whether it actually helps I can’t make any claims, but I get pretty damn good MPG in both my cars and my LGT fuel trims are usually in fine shape. 

Oohhh  Thank you.  If I get some MPG benefit - great.  It's a cheap try.  And as long as I don't 'hurt/harm' anything, I'm happy.  

Do either of these items work?  Do the help save gas, get more mileage per tank?  Are they safe?  

ANY input/suggestion/knowledge on this would be greatly appreciated.  

I have had my 2015 Subaru Legacy for just over a year.  Knock on wood ... it has been running great.  I thought maybe these additives might help.  THX!

I have a bottle of that as well, and after use, I still prefer the water/cloth method. Gets rid of that Subaru windshield grime...

I see this is an old post - but I am SO happy to see people talk about that grime!!!  I have been trying to figure out why the inside of my windshield is grimy!!!  I do NOT smoke!
