At what concentration of WMO to diesel starts to cause problems in cold weather? Assuming using winter blend with Power Service's antigel.

First off WEO/WMO rated very poorly on the HFRR tesing and so did the PS. So your going to cause more damage to the fuel system with the combo. With high ratio of WEO/WMO it might rank better but still not a viable solution with vicosity that is 100-140 cSt and diesel is between 2-8 cSt... Anti-gel isn't going to change that...

What outside temperature will you start having problems using Walmarts TCW3 two stroke at small amounts? Like about a quart or so in a tank.

I've tested 2 cycle oil at 128:1 ratio down to -20*F and never had a problem period.

Thanks,
Jim

PS---Please do not use my post to further the pissing matches, thank you.

Nope... Just going to post the fact I have on hand nothing more...

You said "I've tested 2 cycle oil at 128:1 ratio down to -20*F and never had a problem period." Ok, I am new to having my own diesel. I live in WV and assume we get winter blended fuel. Does a person need antigel here? What happens when you add the two stroke? I mean, does it help or hinder geling? Does it do neither?

Someone else may have to answer this question. Is WMO blended with diesel more or less prone to gelling?

Just trying to learn.

Ok learning curve for ya... :thumbsup

Ok I'll give you this much the anti-gel is actually called "
pour point depressant". Here do a bit of read here in the search I did...
pour point depressant - Google Search=

So now both 2 cycle oil and #2 Diesel use the same pour point depressants so if normal diesel has a pour point to roughly -20*F and snowmobile 2 cycle oil is down to -40*F and it has the same pour point depressants. I would say it help it.

Pour point is when your substance is completely solid and doesn't pour (frozen solid).

Cloud point is when the substance is still fluid but wax crystals start forming.

So now if you check out some of the high performance snowmobile oils you find some as low as -50*F for a pour point. So this would be the excellent 2 cycle oil to add to the fuel knowing that the same pour point depressant is present in the 2 cycle oil.

NOTE: Synthetic 2 cycle oil have no wax in there contents so they do NOT contain any kind of pour point depressant. They will not aid in the pour point temps at all. Synthetic oils are produced in a lab from non-pteroleum stock so they are natural low pour point temps...

WMO might and it might not change the pour point of diesel fuel. But it will change the viscosity (making it thicker) which will cause damage to the IP pump and injectors in cold winters. Remember Cummins fuel system are intended to run 1 cSt to 5 cSt viscosity. Not 100-140 cSt which engine oil is... This becomes even thickier in the winter time cold..

I too am curious to hear from the people that are running high concentrations of WMO in the winter months. Is this just your summer time program or do you run it year round?

[shorthair]

Mopar since I don't own a vp pump & don't ever intend to I won't worry about it but I do have over 4 years experince with WMO in a db2 pump & it worked just fine down to 0* at blends of 50% without using a block heater. I will keep my P pump & be happy with cheap parts & ease of replacement plus it'll run on near anything that will burn. P.S. even 140 gear lube.

Do you lessen the ratio during the winter months? Is this a " I'll pour it in when I can find it " or do you try to run a specific ratio?

Remember that there is all generations of truck looking at this thread... It might work just fine for you P7100 pump but there is several other fuel system it won't work good on...

vp44 is worthless.... thats all there is to it. i have ran ATF, and used motor oil and cold starts are a little slow but still ok... the p7100 will take a lot gear old and hydrolic oil one of them it gets thick but it still does alright

Might be true its worthless but take care of a VP44 properly and keep your truck in good shape I'll blow you out of the water with better fuel mileage...



Or my record high..


I've got 85K miles on this VP44 and doing just fine. Cranking out high MPG numbers...:thumbsup

Yeah the P-pump engines should be called multi-fuel engines, they seem to run on anything diesel, kero, WVO, WMO, rat piss.

others with performance upgrades have mentioned that on b100 they aren't able to produce the black smoke clouds like on diesel,this could suggest they are burning something less polluting and perhaps with quite different properties than diesel,we have a member in Alaska who is having great results on his homebrew bio in a common rail cummins, i believe they dilute it in the coldest weather

I'm ok with not being able to make black smoke. I would actually prefer not to. It's just wasted fuel going out into the air. You have to blend in the winter to prevent fuel gelling. Both of my vehicles are on a B75 or B80 mix right now. It's been droping just below freezing at night sometimes.
