It's approaching winter and I want some opinions on diesel treatment. Where I live in Wyoming we can (on occasion) get down to -40 F and I already run synthetic oil. What I want to know what diesel treatment is the best? I have heard that powerservice (white bottle) can be hard on 6.0l's. I have also heard that Howe's is one of the best but I want your opinion. Also along the same lines I had a mechanic tell me that a couple ounces per tank of 2 cycle oil is good to keep the injectors lubed good! Thanks fellas!

 

I have used Howe's with #2 diesle for years with no problems.

 

I'm from Great Falls, MT. And like Wyoming it gets a little cold in the winter. I use Stanadyne Performance Formula. I've never had a single problem starting in the cold weather. Also I run it every other tank in the summer to help take care of my injectors.

 

Granted this morning it wasn't very cold(only 22) but I run shell t6 fully synthetic 5w-40 and my 6.0l with brand new injectors started like it was hot.

 

Everyone ready for some science? I use opti-lube XPD (sometimes use the winter formular too) year round.

Here's why:

Howe's barely does anything for lubrication, and stanadyne is the same, unless you get the lubricity formula specifically, but that does nothing for cold weather. Opti-lube FTW!!!

Thanks for the post - I have been using Power Service - guess it is time to change.

Is the opti-lube XPD an "over the counter" product or a mail order?

 

I've been buying it online forever. I know there are some places that sell it locally. I believe they had a dealer locator on their website actually. Not a lot of local dealers it looks like, but worth checking: Opti-Lube Diesel Fuel Improver | Grease | Oil Fortifier

Looks like diesel power mag did a test at some point too: Fuel Additive Test - Ultra-Low Sulfur Diesel - Diesel Power Magazine

 

I took a 20 oz. soda bottle and drew a line 15 oz. up. I run 15 oz. of howes and 5 oz. of ashless 2 stroke outboard oil when I fill the tank. During the summer I run the RevX distance+ every other tank and that **** makes a difference haha. I know howes isnt the best for lubricity in the top-end but its always been good from anti-gelling, and the two stroke oil is pretty good for lubricity. You could hear how quiet the motor got after switching from the diesel-kleen on cold starts

 

They did 2-stroke oil in that comparison test... you can see the results for yourself.

I've never once had my fuel gel up on me, BUT I have had it freeze.

The biggest thing when running anti-gel stuff. The fuel seems to freeze no matter what, if it's in there or not, but if you ARE using it, it will thaw back out, where if you're not running it seems to stay in a gel form.

 

Since different additives are discussed has anybody used or heard of Hot Shot Secrets for stiction problems. I saw their ad in Land Line Magazine (OOIDA publication) and they claim it will 'ELIMINATE STICTION - We guarantee it.'
