Purchases 2x cases of this for a Turo fleet. Additive is poly ether amine, (pea). Beware: the instructions say to pour this into a nearly empty tank and promptly fill up.
I erroneous assumed this was a suggestion to help the detergent work by using fresh gas with minimal water contamination. However, there was a second reason of which I was unaware (it seems obvious now, but I do with the instructions explained WHY to do things, for better product education).
I violated the instructions, pouring it into a Mercedes ML350, and did not top off with gas. Little did I know, Benz uses a bunch of complex plastic pieces in the gas tank neck, bonded together with plastic adhesive.
The adhesive appears to have been dissolved by the ether, the residue sitting in the tank neck allowed to pool at the seam until it was compromised, throwing an evap leak. I bought a smoke machine and discovered that I probably caused this issue via lackadaisical adherence to the instructions.
Lesson for me, contained in no literature: Concentrated poly ethers may dissolves plastic bonding agents used on Benz vehicles.
