Stopped at the dealer the other day to purchase the maintenance package and asked about fuel additives and they carry this one at the dealership. The service manager says it's good for gas or diesel engines. My question- does anyone have experience with this product? Seems to be legit being offered at the dealership I just want a real world opinion. Thanks all.

Just because your dealership is selling it doesn't make it legit. On the whole, for modern gas engines, any pour-in fuel additives are useless. Some can actually be harmful.

Agreed - snake oil. Stay away, far away.

If you fill your tank with Top Tier fuel, it will already contain the detergents/additives recommended by Audi.

BG44K is one of the best and strongest fuel additive with a very high concentration of PEA. What you want to do though is run it in the fuel right before an oil change as the BG44k is powerful enough to really thin out your oil. Dump it in an empty gas tank fill it up and run it to near empty and do an oil change. You'd prolly get a better price on ebay. Lots sell it there for better prices. Other alternatives that are great are Royal Purple max clean(i use this since i love RP products), Red line SI-1, Amsoil PI, Shell's Gumout with Regane and Chevron with Techron. But BG44k is the strongest of all and it may not be necessary in a newer vehicle. The others should suffice and always follow the same directions for all fuel injector cleaners.
