i know were suppose to use the white bottles in the winter and grey in the summer...but a friend who use to have a diesel had a few grey left over...would there be any harm in adding them despite it being winter? or is it just recommended to use the white cuz it has the anti gel agent in it? thanks

 

Grey Bottle does not state that it lacks anti-gel. white bottle says it has anti-gel.

Wally world has DK 911 for 4.00 a bottle which would make grey bottle same as white bottle, but at 1/2 typical dose.

Doesn't get cold enough here in Reno to tell if the anti-gel is working, but #8 rattles more on white.

 

I would wait a month, when the weather in the N.E. stays above freezing than use it

 

If you're in New England, wait for it to warm up before swapping to the silver bottle. I'm finishing my white bottle off now -- I used a bunch in it this week because I had B100 in the tank and it dropped into the upper 20s. Put in a double-dose of DK and topped off with dino the next morning (it was in the low 40s by then). No problems with gelling, thankfully. Good stuff!!

 

it's gotten below 0* here in IN a few times, ALL I ever run is the silver bottle.. not a problem yet. just my .02

 

Here is an interesting report on the lubricity issue of fuel additives. Dieselkleen did not do well, but if you are running biodiesel as much as 2% you are getting the best lubrication for your injectors & fuel pump/system.

Jump to the last page, great chart layout

 

I run gray all the time. I dont think they differ too much other then an anit-gel in the white. - From temps 0*-90*. Gotta love this Michigan weather.!

 

jeeze.. kinda wondering if I should be running lucas now?? thought it does give me a few more MPG..

 

I wouldn't trust anything from Lucas after what their oil additive made my truck do. DK for fuel is what i use, and SOMETIMES stp in the oil. DINO BTW.

 

Don't panic with DK. The fuel they used for testing was completely untreated "dry" ULSD. So even though DK didn't bring the lubricity up to "strictest requirements requested by the Engine Manufacturers Association", it did bring the HFRR score down 61 points. If ULSD you get from the pump "only" meets the US standard of 520, adding DK brings it just below the 460 mark set by engine manufacturers. I'll keep running it.

From the report:
"The independent research firm obtained a quantity of “untreated” ULSD fuel
from a supplier. This fuel was basic ULSD fuel intended for use in diesel
engines. However, this sample was acquired PRIOR to any attempt to
additize the fuel for the purpose of replacing lost lubricity. In other words, it
was a “worst case scenario, very dry diesel fuel” that would likely cause
damage to any fuel delivery system. The fuel was tested using the HFRR
testing facility at the Laboratory. This fuel was determined to have a
very high HFRR score of 636 microns, typical of an untreated ULSD
fuel."

Also from the report:
"CONCLUSIONS:
Products 1 through 4 were able to improve the unadditized fuel to an
HFRR score of 460 or better. This meets the strictest requirements
requested by the Engine Manufacturers Association.

Products 1 through 9 were able to improve the unadditized fuel to an
HFRR score of 520 or better, meeting the U.S. diesel fuel requirements for
maximum wear scar in a commercially available diesel fuel."

DK:
"Multi-purpose
Cetane improver, bio-diesel compatible, alcohol free
HFRR 575, 61 micron improvement"

 

I follow your train of thought Joe, and understand your point. But if you go with a product in the top 9 then your always covered as far as lubricity is concerned, treated or untreated fuel.

In your situation, you are running biodiesel so you have the best lubricity and are just mainly after the cetane boost and other benefits of a fuel additive.

 

I don't always run BD -- only when I happen to be near a station. None are close to my house or work. In fact, I think I'll quit running it full strength. I got beat by a damn Nissan running B100. Topped it off with Dino (to less than B50) and I was back to smoking ricers (both literally and figuratively!!).

EDIT: BTW, I look forward to trying out the DT!! Thanks again!!

 

Well, to check how your biodiesel is acting in the cool morning you can drain a bit out into a jar from the filter bowl and sit it out over night, see how it looks in the morning. I'm no biodiesel expert but when Luke brought some 100% to the track in Noble last year - it was around 40 degrees outside and that stuff poured out like applesauce.

 

YIKES!! Did he put anything in it?? I dropped in a double dose of DK and plugged in the truck. Also, it was in my garage until the morning. Then I dropped my daughter off at school and went straight to the station and put in 15 1/2 gallons of dino. Didn't seem to have any problems.
