Hey everyone this is my first post here. i've had my 2012 jetta TDI for almost a year now.
Recently been trying to just learn as much as i can about how it all works. very new to me and interesting the amount of technology in these things. But i was wondering why is the fuel pressure so high ? 26000 psi is crazy. just wondering what that achieves. also who has the "best" diesel fuel? my buddies are always saying oh safeway gas is **** blah blah. i usually get my diesel from a wawa close to me. sometimes a 7-11. i just want to be sure im not getting "bad" fuel.
