Being a desert rat my truck seldom sees temps below freezing. We are heading North for Christmas and the predicted temps where we will be staying are close to zero degrees F overnight and freezing to barely above in the daytime. I presently use Stanadyne Performance Formula which claims "Cold Weather Protection – improves diesel pour point up to 40°F (22°C), and cold filter plug point by up to 25°F (13°C), depending on base fuel " on the spec sheet. I also supplement the Stanadyne with Optilube. (I like the Stanadyne for the Cetane boost but it does nothing for lubricity).

Question for you cold weather dwellers, what should I add in addition for zero temps? I read that Power Service is only good into the 30's.

 

I live in PA and we see cold weather a lot. I use the Lucas anti-gel as well as Power Service Supplement and Cetane Booster and I also keep a bottle of Power Service Diesel 911 in my truck in the winter.

 

Here's what I use and often hear others speak of using it as well.
It is available almost everywhere.

I use this year round. You can buy it directly from Archoil or from EBay or Amazon. This one bottle treats 500 gallons of fuel. If you haven't already find the plug for your block heater so you can plug your truck in.

Search or google for a fuel treat performance chart that pops up here & other places,then You can pick out of the top contenders available in your area.

 

That's what I use too, in the winter. I use the silver bottle in the summer.
It is available just about everywhere, including Walmart

In both cases, I blend it with the Stanadyne Lubricity formula. https://www.tractorsupply.com/tsc/pr...iAAEgKAiPD_BwE
I have had a hard time finding it since Advance AutoParts stopped carrying. I ended up buying a case of it on Amaazon or Ebay.
I take one 80oz bottle of the PowerService, and I split the bottle in half. I use empties from prior use, but obviously the first time you do it, you won't have a second empty bottle. So, I have 40oz of the Power Service, to which I 1 whole bottle (16oz) of the Stanadyne Lubricity. Shake it up good to mix. I now pour that mix back into the empty 16oz Stanadyne bottle. I fill it up. That bottle goes with me to the gas station, and I add the whole thing just before filling up the tank. So, 16oz of the Power Service/Stanadyne mix to approx 30+ gallons of fuel
I usually run my tank nearly empty, and then fill up. I try not to do $10 here, $20 there kind of stuff. A.) Its more time wasted stopping for fuel, and B.) Its harder to calculate how much additive to use, C.) Its also harder to monitor fuel mileage with partial fills.


Also, I agree with some other posts. At zero degree temps, it would really be a good idea to plug in the block heater overnight. Yes, the truck should start without it. But, it will likely make the neighbors unhappy, with the not just the noise, but also the large cloud of stinky white smoke that will be produced until the truck warms up.

Speaking of faster warmup, I would get or make a grill block off. Since this is apparently a temporary visit, you could just make one out of cardboard. I did that when I first got my truck. I used a large piece of cardboard, trimmed to shape of the grill, and covered in 2 layers of clear packing tape, then zip tied it to the grill. It lasted all winter. Only started to fall apart in the warm wet spring. I have since purchased a true grill block/blanket.

Its $90 here. I think I paid less then that when I bought mine off ebay.
I put it on when the temp get into the 40s. I leave the 2 flaps open until about freezing, then they get closed. It makes a big difference in warmup time, and it helps the truck to stay warm going down the highway and especially if you are sitting idle in traffic. And no, the truck has never overheated with it on. These trucks have massively oversized cooling systems, especially when running empty or lightly loaded.

 

Stanadyne is all I use. I run it year round and never had a gel issue.

__________________________________________________ ______________________Not true about the lubricity. Not as much as some of the products available, but up near the top of the list just the same. There are different formulations of Stanadyne so some reading is in order.

 

I'd say as long as your glow plugs are working and you have good batteries, you're good to go! Your choice of additives is fine too.

 

This and only this. I live in Colorado, -22Celsius scheduled for this Thursday -I will be starting my Truck without plugging it in without issues 100%.

 

 

Gotta go metric someday, everyone else is.

I use the performance formula which does not have the lubricity additive (see chart). I also remember a study a few years back where Stanadyne Performance came in very poor on the lubricity test. Many people are familiar with that test, it is what brought Optilube fame and fortune.
