Part Number A 000 989 25 45 12. I beleive this is basically BASF Keropur 3131. Anybody using this at all?
Picked up a couple of these to try specifically on the ML500, but also dumped a can in the Grand Marquis when I had 3/4 of a tank remaining (1 can is for 65L of gas). Dealer recommends adding this to the fuel at every fill up, but considering one can only treats 65L and the ML500 has a 95L capacity, I wait until there's 3/4 of a tank remaining. Reckon it's useless otherwise.
I haven't yet noticed a different in the GMQ, possibly because I'm running Liqui-Moly Ventil Sauber valve cleaner on a regular basis, but the Mercedes has noticeably better idle and pick up.
