Oil & Fuel Diesel is clouded again!!

[LBrown59]

1* use #1 diesel - the simple solution. It has a cloud point of -40 F. I

1*Then why are so many reporting problems with it at temperatures much higher than Minus 40?

Diesel Fuel Supplementｮ +Cetane Boostｮ is our antigel product it provides superior protection for cold-weather operability. This is the product to use during the winter months to prevent fuel gelling down to -40ｰF. and equal the performance of a 50/50 blend of No. 2 and No. 1 diesel fuels.

If Power Service is equivalent to that diesel blend, then I'm really hosed. I gelled up worse with the power service the last time it happened. I just got home from work and the filter looks worse than this morning. We're at about 20 deg right now. Tomorrow is supposed to be a big warm up so I'm going to replace the filter and find a new source for diesel.

I have got to tell you this makes no sense. If the peformance they are talking about is cloud point.

#2 diesel - cloud point +40
#1 diesel - cloud point -40

When you mix 50% #1 and 50% #2, you get a cloud point of 0, not -40F.

Also when they say This is the product to use during the winter months to prevent fuel gelling down to -40ï½°F., what grade of diesel are they talking about #1 or #2. If they are talking about #1, I am unimpressed since it doesn't gel until -40F in any event.

Who are the many you speak of? Can you name one of the many?

In any event the answer is simple, they aren't using pure #1 diesel.

A question for anyone who knows. Do some 18 Wheeler type trucks have heaters in the fuel sytem that allow them to run #2 in cold temperatures? I though a trucker told me that once

This site:

Recommended Guideline on Diesel Fuel

looks pretty good for giving good explanations of fuel properties.

One point I thought was interesting...they claim the retailer's supplier is responsible for keeping the fuel usable, and often will adjust it on a monthly basis based on expected temperatures.

One member asked if you were using old fuel. One would think that if you use fresh fuel from a reputable distributors, your fuel will be fine. This makes sense to me because for it to be otherwise would chaos.

you can buy aftermarket filters that have heaters (Raycor, e.g.) and as the tractor runs the fuel return puts warmer fuel back into the tank...

if you go to the power service website you can see their arctic stuff, which is like the kero with which you can blend your own. and, note that PS in the gray container does not (not) have anti-gel properties.

You may (also) have water in the fuel ...truck worry about this, too and my superduty and older diesel suburban each have fuel-water separators that should be drained once a month

on your tractor, look for a cute little bubble in your filter bowl and/or drain some fuel from lowest point into clear container and check ...aftermarket filter installations can also include water separators w. warning light. Power service 911 will take care of some water and "de-gel" fuel at cold temps.

I still have last summers #2 blend in my tractors because that's what I had left in this set up when winter hit.

I treated it with .58 OZ. of power service per gallon been working fine so far this winter.
**That's is correct,but I haven't bought any winter blend this year as I am still using last summers summer blend that I had left over.

Thanks for this info. I'm fairly certain it is not a water problem. The diesel came from a convenience store. I'm in a rural area so who knows how fresh it is or whether it's leftover from Summer.

1* I guess everybody who's started a thread on TBN in the past few weeks about having gelling problems.
How did you miss them?
2* What do you mean by Pure #1 diesel?
Around here we have #2 in the summer and #1 in the winter.
It don't get any purer or simpler than that.

 

[LBrown59]

Truck stops in CNY have both #1 and #2 diesel pumps.

Why do they still have #2 summer blend in the dead of winter?
All we have is #1 winter blend.
#2 summer blend won't be available till spring.
