My Fabulous 1992 190E 2.0L Mercedes-Benz, a fine comfortable ride, that has since my possession(2014); had gas to gel and required blowing out! Initially using ANY premium, my mechanic advised three gas brands- I chose shell in 2015.
Since Spring, 2018 it has been sputtering -off and on (came very close to completely stopping New Years Eve night 2018). Sputtering most notably occurs following pull-off after coming to a full stop and on this occasion continued for about 1 mile- in traffic. After accelerating car drives with no sputters-40 minute or 4 hour drive-until next full stop. Wondered if gas line again needs blowing out?
Recently read article “Why are we using blended gasoline and ethanol?”. What is the potential that "Ethanol (being) a hydrophilic, meaning it holds water- cause my problem in a car of the era?
