I won't void your warranty. It's always a good idea in my opinion, especially in your climate. I run Stanadyne every tank.

You do need to run something to lubricate the injectors. Depending on your use it should be something that will clean them too. Don't need to run it every tank but need to do it on a regular basis.

No warranty issues. They have to prove the additive caused a specific problem, that's not going to happen.

I use Amsoil Diesel Concentrate with Cold Flow Improver. PM me for discount pricing.

As far as the fuel additive, use it if you want. It will not void your warranty. Besides, they'll never know anyhow.

GM recommends Stanadyne anyway. I use the Lubricity Formula and the Amsoil Cetane Booster. I just want to make sure I have quality fuel.

Like others, stanadyne is the way to go. In North Dakota, I accidentally filled up with #2 and temp dropped to -10 and it didn't gel on me with just stanadyne.

Congrats on your truck purchase. I put Stanadyne in my fuel tank at every fill up. So far so good.
