The best diesel comes from the pumps that move lots of diesel. I usually go for the lowest cost because they move more fuel. Also, I always dump in some vitamins as my daughter called them. Mostly a 2 stroke power service mix for my ALH.
What jayb79 and autoguru21 said. Get your diesel fuel where everybody else does in your area. Go where the big rigs go to fuel up along major routes. Always use an additive with every tankful to take care of any water you can't avoid getting and to increase lubricity. My two favorite additives are Howes Lubricator Diesel Treat and PowerService Diesel Fuel Supplement (white bottle).I go fill up where the semi's get fuel, guaranteed high fuel turnover and i've never had a fuel system issue, i also add optilube xpd and the lubricant additive every tankfull, i drive a 2015 Golf Sportwagen with the sel package which includes the xenon lighting package
Thanks a lot appreciate all of the info. That’s a little bit out of my way but sounds like it’d be well worth the drive.What jayb79 and autoguru21 said.

Avoiding water is critically important during the winter months due to condensation being more of a problem. This is also why it is important to fuel up ONLY at high diesel turnover stations along major routes. The fuel at these stations is constantly being replaced, almost daily. Wherever you fuel up, absolutely AVOID fueling up at low turnover stations that rarely get any heavy truck traffic.
Water in diesel fuel ices up in the cold and imitates gelling problems. People often mistake icing for gelling. They think they have gelling problems but actually have icing instead due to water from condensation. Diesel fuel normally is winterized for the region and won't gel at the coldest temps that we encounter but icing due to water can get you in trouble long before gelling will. Water in diesel fuel destroys pumps and injectors in no time at all and absolutely must be avoided at ALL costs! A single tank of water contaminated fuel from condensation from a low turnover station is all it takes so avoid low turnover stations at ALL costs. The HPFP in the CR TDIs appear to be getting destroyed by free water in diesel fuel, not from poor lubricity although it is a factor too. Avoid the water!
My favorite busy truck stop along the I-93 corridor in NH is RMZ Truck Stop at Exit 5 in Londonderry. This truck stop has a C-store and NH State Liquor Store and the Red Arrow Diner as anchor stores so it gets lots of business. The back of the station has room for trucks to park and it's always full of trucks. The diesel pumps are in the back of the station and away from the gassers. This truck stop gets an entire tanker of diesel emptied there every day to keep up with diesel demand from the high volume of heavy truck traffic. I have no worries about water in diesel fuel at this station.
The bottom line is fuel quality is ABSOLUTELY EVERYTHING(!) when it comes to protecting pumps and injectors and ensuring long life and reliable service from fuel system components.
