Fuel problem
 

I've been using Chevron super unleaded for a long long time. Recently changed to 76 station because I've had some startup hesitation and pinging. What a difference!! I don't know if I have been ripped off for how long by this particular station or it is better to change the brand from time to time? It seems that some WA state pump stations have been cheating on customers.

I have talked to people who claim that gas makes a difference in performance and smoothness. I always thought they were pulling my chains, but I am beginning to believe this stuff.

Mattttt,
What model Mercedes do you have?
