Bottle states DOES contain polyetheramine (P.E.A.)
Correct item was sent and in perfect condition. This item states has P.E.A. (polyetheramine) yet the information online states it contains an alternative form of P.E.A. and the SDS directly from the manufacturer states it does not contain any P.E.A. Regardless, this stuff works very well and as long as the bottle states it has polyetheramine, I’ll keep using.

Use every 5k miles
I use this every 5000 miles or so in each of my cars. Really seems to work well. keeps water out of the tank and lines and seems to keep it all running smoothly.

Expensive but only gas additive i believe in
I have a P0420 code that comes on once in a while in a previously neglected BMW (probably from the previous owner using cheap gas) and I swear this is the only thing that makes it go away. The code has only come back on several months after using 2 cans/tank fulls and after 2 cans/tankfuls again the check engine light remains off. I highly recommend using this product periodically maybe every oil change if you own a high mileage vehicle requiring premium fuel as it definetly helps. You could probably use it in a regular vehicle as well but not sure if its as needed.

Berryman's IS THE BEST!
1983 Honda V65 Magna, 4-carbs, in a garage for 2 years with gas in tank. $1,000 carb rebuild quote from a local bike repair shop versus using 2 cans of this! Bike runs like new!
