Best Diesel Anti-Gelling Additive?

I have 369,000 miles on my 2007 Duramax and I have been using Stanadyne since day one...  That’s all I should need to say..

This is actually what the local performance diesel shop sold me a case of.

I know not a diesel....

Been having poor oil pressure. All sign pointed to replacing o ring on oil pickup tube....

Bottom of oil pan....
Had this 3/16ths inch of a pancake on bottom


I got truck used with 96k on it. I changed oil every time the computer told me too.
I’ll be switching to every 3k miles now.

conventional or synthetic? 

[specialblend07]

I on average change my oil (synthetic) every 15k-20k miles. I drive about 50-60k a year. Since I started driving in 2003 I've had 8 cars, I've never had one motor issue.

I use synthetic.
The way the crap was in pan makes me doubt previous owner maintained very well.
Truck has most likely seen A LOT of off road and dusty conditions. Had stock air cleaner setup on it when I bought it.
