Just picked up my 05, 2500HD Crew Cab, 4X4 Silverado today. All dressed in red kind of reminded me of my lovely bride http://www.dieselplace.com/forum/smileys/smiley17.gif i dont think i will get any sleep tonight. This is my first diesel and being from up here in Gods country (North Dakota) where freeze-in is the reason and 40 below keeps the rift raft out i sure could use some clarification on what type additives i should be using with my fuel and how often for lubrication, moisture etc. if any. The owners manual says " Diesel fuel or fuel additives not recommended in this manual could damage your fuel system and engine" and then it reads " if you think you need it consult your dealer " and there is no hint to what you can use, and all my friends say its a must. So if any of you have any experience with real cold climates and these duramax's would you mind shedding some light for this green horn. If i could get that truck up the stairs i would park at the foot of the bed next to my two labs Duke and Molly.


Thanks, Phil

GM recommends Stanadyne Performance formula if you wish to use something. It takes care of pretty much everything from gelling to lubrication and water separation. I use it regularly and think it is a good product. There are others out there, but not actually recommended by GM. You can buy it online from several different places. They make it in handy 8 oz. bottles that will treat one tank. Buy a case and save $.

Sorry I don't have info for you since I live in So.Cal, but wanted to say congrats on the 05 D/A http://www.dieselplace.com/forum/smileys/smiley2.gif

Congrats on the new rig!

Hey Bartman,


Thanks i am originally from New Mexico Whispering Cedars just east of Alb. on the back side of the Sandia's and my folks and and a couple brothers live in Alb. now.

Phillip,
Pretty small world we live in. Even though it doesnt get very cold here in Albuquerque, we frequently go to southern Colorado in the dead of winter, where it can reach the 10-15 below zero range. I would definitely keep it garaged if you can, or use your block heater. Plug it in as soon as you shut it off when you get home, and it should keep it nice and warm overnight.

Just ordered a case of 8oz bottles of stanadyne for my 2005. May not get as cold here in MN but cold enough!

I use Stanadyne Performance formula and my truck runs much better. I buy it here. I've found they have the best prices.

Phillip,


congrats on your new ride.... as far a additives go.... being from God's country myself...North Dakota... I have been using Power Services Artic Express in the winter for about 10 years now and haven't gelled any of my diesels (a 6.5, a cummins, and my 04 LLY duramax)up yet...Behms truck stop should carry it... sometimes Wal-mart does too. Stanadynes winter additive is supposed to be better but is harder to find. John Deere makes a good one too, but Artic Express has been in my experience easier to find and hasn't let me down yet... I did a search on the net for cold weather additives and these were the top 3, with Stanadyne being the top one. I don't run #1 fuel either just straight #2 with artic express in the winter and diesel kleen in the summer.


good luck and enjoy your truck

You should be very careful to avoid any additives. Your new truck has converters that might get clogged or damaged. GM reports that Standyne can be used if you suspect some conditions.


Can't see how you could not run what the local dealers supply. Usually when it gets cold they go up to #1 up north. That is what I would run if I had a choice in winter. In Tx I have yet to see it cold enough to look for anything but #2.

Been using primrose since new with no problems, it is supposed to be as good or better than standyne but a little cheaper.

In wisconsin, it's damn hard to find straight #2 in the winter, most of the stations around here start blending fuel as the temperatures drop....While it might say #2 on the pump, by the dead of winter it's usually a 60/40 mix from what I've seen...


Oh, and congrats on the new truck Phillip!
