Do NOT use summer D2 in winter

nursecosmo · **Posted:** Wed Feb 18, 2009 7:36 pm

north of the Mason Dixon line. I have been using #2 Clear diesel in my Dodge Ram now that the weather has warmed up a little (-5 degrees and up). It will stumble a little when I start in the morning but gets superior mileage and is about 10 cents cheaper. Now, my Ram has the venerable 12 valve Cumins with a piston powered lift pump and the bullet proof P7100 injection pump. The CRD doesn't. I tried putting the same #2 clear (summer diesel) into my Jeep last week with a double shot of Power Service White. Next morning 0* and the little woman had neglected to plug it in the night before. Guess what happened. Yep, it wouldn't start at all until the block heater had warmed it up and I had attacked the filter canister and fuel lines with a blow torch. Even then it also took a can of starting fluid, a whole bottle of PS white and the assistance of the two big batteries in my Dodge Ram. I could not apply more than Half accelerator for the rest of the day because the fuel just would not push through the filter. Fortunately the temp warmed up into the 30s and 40s for the rest of the week.

The lesson to be learned from this: The fuel delivery system in the CRD cannot handle syrupy fuel.

Dude, seriously, you need a real lift pump...

Ok, just having a bit'o'fun, but I have done the upgrade to the in-tank model and it's nice not to have to worry about that anymore. It solves a lot of problems.. air buildup in the filter head, higher viscosity fuel, and makes the system much more forgiving.

My LP has a higher pressure than the in-tank one. When the fuel is like thick molasses no electric lift pump will move it through the filter. The viscosity dependent nature of our injection system also requires that the fuel be liquid.

Sounds waxed up to me.

Not just wax. The fuel itself was the consistency of Karo.

I think the lesson is more like this: Use winter diesel in the winter.

in Texas - really, really cold is 40F

Another of the reasons I'm looking forward to living there.

Not necessarily. I can run it in my Dodge without issue. Of course, the Cumins has a 40 psi piston powered lift pump and positive displacement inline injection pump. If the fuel can be moved at all it WILL be injected, no mater how thick it is. In the CRD, injection quantity is a function of viscosity vs injector energizing time. If the the fuel is twice as thick as normal, only one half of the normal amount of fuel will be injected. We also have a smaller, more restrictive fuel filter which has to be overcome by a weaker lift pump.

In the CRD yes. Use only winter diesel in winter.

"Even then it also took a can of starting fluid"

as in regular ether based starting fluid ?

....you use starting fluid on a diesel with glow plugs. Or the BATFE may come pay you a visit and not be asking you anything about your guns, your still, or any thing about the tobacco growing in the Garden. If the NTSB shows up, spray paint a small cardboard box with Orange paint, tell them it is a black box, give it to them and send them on their way.

:lol:

Why would the BATF give a rat's patootie about starting fluid. They might have something to say about my still though

Diesel + starting fluid= job security for me!!!

BATFE and the E=EXPLOSIVES

BTW: Drink your own booze and not sell it, they couldn't care less.

If you want to have fun with BATFE tell them that the guys at your local Waster Water Plant are brewing MIXED LIQUOR (the poop being aerated)

DO NOT USE STARTING FLUID IN A DIESEL PERIOD.I have and always use spray silicone on my two diesels(CRD,Ford X) this helps with starting and unlike ether adds lubrication to your fuel system.I have use this on over a dozen trucks (12 wheels to 4 it doesn't matter its your safert bet).

Coldest temps I've started my CRD in is 17 degrees. We don't get anything by #2 diesel here (that I know of).

Took longer to start, but it started on the first crank. I ran a little rough at first, but motored on.

Silicone spray can in no way add lubrication to the fuel system when it is inducted through the air intake. When silicone combusts, it makes a sticky mess inside the cylinder (as an experiment, spray some onto a metal surface and light it ). Many OTR trucks have used factory designed ether for ignition for many years without issue. The trick is not to use it in temperatures above 20* or so. If it is used in warm temps a blown head gasket is likely to occur. I have used it carefully for many years without a single problem, but have seen some hacks blow their engines by using too much or at too high of an ambient temp. Also DON'T use it on an engine with a grid heater.

...a few things....

Silicone is a pretty good lubricant when modified or has additives. By itself, it's just okay. It's popular for many uses because it has a flatter viscosity versus temperature profile than petroleum based lubes. It is also a little more resistant to oxidation. The gel point is also very low.

The most important reason NOT to use silicone spray to start an engine...the combustion products are silica and carbon dioxide. Silica is highly purified sand. Purposely adding it to the combustion chamber is inviting premature wear. One would be better off with WD-40 in this instance.

Any place where it gets cold enough for me to consider having to use starting fluid on the CRD, is too bloody cold for me to be living there to begin with. :wink:
