Keep a bottle of Diesel 911 around as well, good stuff for drying out watery fuel. If your '93 is like my '82 300D, there is no heater on the fuel filter. I also try to keep all diesel tanks as full as possible, especially in winter, to cut down on condensation. Mac's Antigel is also available at NAPA, I have a gallon in the basement that I got on sale, fortunately haven't had to use it!

Gas in a TDI (or any modern diesel)? crzy

Gas in old diesels can be OK per the manual, but never in a modern diesel.

I do have a fuel heater on my engine that is thermostatically controlled. At any rate, I am now adding 6 oz. of Diesel Kleen Anti Gel at every fill up. The winter here has been pretty mild so far though.

I usually fill up at about a quarter tank. I hear you about keeping the tank "fuller" to minimize condensation.

That greatly depends on the quality of fuel you buy.

I keep a mason jar of untreated-by-me fuel from my local supplier of B11 in my unheated, uninsulated garage. It has remained bright, clear & completely liquid even at -28C [-17F]. I still tend to dose my fuel with Howes Diesel Treat or PS White once temps start straying down to -15C [low single digits F]. Never had a gelling problem or iced up fuel filter.

Especially with modern diesels, buying the highest quality fuel you can find is one key to long-term value.

I use Howe's Diesel Treat. I can get it in all of the chain auto stores or any travel plaza serving trucks. I also use it in my heating oil, and my heating tech comments on how clean the system is at each annual service.

Gelling is only one problem. Icing is another. You need to have an additive that tackles both. There is almost always traces of water in diesel. Usually not a problem. But when it is, it is a big one. I go thru around 21,000 gallons of diesel a year, so I can't afford to run into problems. But I am prepared. Over the years, I have grown fond of the Amsoil line of diesel fuel additives. Their Cold Flow Improver is pretty good. Recently, the son of a friend approached me about XLP Diesel Fuel additive. I dug around looking at specs for it online, and it is pretty close to the Amsoil stuff. It is made by an outfit in Olathe, KS under contract from Chevron for, if you can believe this, Amway! Price at application rate seems reasonable... 2/3 the cost of Amsoil line. I am going to be a guinea pig and test this stuff all this winter.

Since having my semi truck operational with low problems is critical in winter, I start putting additive in when we approach 32F. I get fuel from a variety of locations around the upper midwest, and even the top name outlets have occasionally had a load of fuel that didn't hold up well in cold temps. I don't play games and take chances. A gel up or other problem 700 miles from the house is not a good thing. I always carry spare fuel filters and additives.
