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 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!
