Diesel and frost

Hi Guys,

I would like to know the right ratio of petrol I could mix with the fuel diesel in my MF 165 year 1966. Sometime, it is very freezing here and I would like to start my MF even it is very low temperature. I thouhgt to add 5 liters petrol for 40 liters diesel ? What do you think about that ?
Thanks JJ
 
First, are you in Europe someplace? Here in the USA we don't really know what 'petrol' is. Then, if you are talking about adding gasoline, I have heard not to do it. On my MF I use heat lamps, and additives to the diesel fuel, and I use the MF thermostart system, but I'd never add gasoline. Maybe a person could safely do it, but I wouldn't.
 
Since you asked for a ratio, I'll give you one. Back 'in the day' when nothing else was readily available we would mix about 10 to 1 if it was very cold. Only mildly cold (32F down to 25F) more like 15 to 1. Whether or not it should be done is anybody's opinion.
 
I wouldn't recommend using gasoline but in cold weather they cut diesel with kerosene 4 kero to 6 diesel. That is what is sold at the pumps up here in Maine during the winter months. Also use some diesel fuel conditioner.
 
Thank you for answering Guys !
Here in BELGIUM, the winter could be cold -20 ° C (about -40 ° F if I am right)
Here we call "petrole lampant" the "heating lamp"
I asked this question because we used to cut diesel with gazoline, but it is not recommand with our new diesel engines. So I will use heating lamp rather than gasoline. We do not find kero at the gaz station. So if I use 4 "heating lamp" for 6 diesel ; no danger for my dear old engine ? Sure ?
 
Don't know about over the ocean but over here kerosene is also called #1 and diesel #2 and I have been using the blend for years with n problems. Our winters are comparable to yours with 30 to 40 below zero F.
 
You should aks the people that you buy your diesel from. Do they do like the northern US and Canada? mix it with 'kerosene/parafin', or do they mix other additives to prevent waxing and jelling.
If they do nothing to the fuel because they do not think it will get cold enought to need it, then you should mix about 10-20% parafin/lamp oil/ kerosene, whatever it is callled where you are. Maybe not petrol/gasoline in a newer/modern diesel engine.
By the way, -20C is about 0 F, 40F is about +5C, a diesel 'should' start well above +2C... as I continue to have big problems,with home heat aswell as vehicles, I find that worldwide, diesel is not guaranteed to ignite less than that. If the local company doesn't treat it, the user must.Good luck and stay warm!
 
Glagla like we say...
I am happy to not be the onlyone knowing such winter.
Here most of the time the weather is wet and windy and it is the worst !
Thank you for the information.
Here we have gaz super 1,7 € normal gaz 1,6 € and diesel 1,4 €
We have also for heating system without taxe 0,9 €
and petrole "heating lamp" 0,9 €.
The kerozene is only for planes...

Have good time other there ! JJ
 
Hi Tony,

Clear for me. Here in BELGIUM we are the tax's country. The regular diesel is under tax, only the diesel for heating home system is free tax (0,9 € per liter ). If you were interested to live in BELGIUM.. You are welcome. LoL

Many Thanks
 
JJ, In the UK, and I'm sure most of Europe will be the same, diesel fuel supplied in the winter will have an additve added by your supplier to prevent waxing so you should't need to do anything. Also diluting your diesel may reduce its lubricating capabilities to the detriment of your pump.

Cheers, Ali.
 
Hi Ali,


Like I said just before this reply. Here in Europe, especially in BELGIUM. The fuel diesel, at the gas station, has an additive to prevent waxing. The point is the cost (full tax) It cost the dubble compare to the domestic fuel. When the tractor is not driving on the road, you do not need to use the full tax diesel. The diesel for domestic heating system is colored red and it can not be used on the road... snif !

Thanks Ali, see you soon again on the forum.
 
Well then I think your cold weather problem is avoided by the same additives as in the US or UK. And the price for home heating oil seems to be within pennies as here- the world price? BUT, as in the states, you had better ask the police before you drive down the road in a diesel tractor with your tax free home heating oil or red farm diesel, but, I would not want the police to find it in your Peugeot 504....
my house is having 'algae' problems we didn't have before, so it lives on additives...
 
its in the book for my 1993 vw diesel to mix gasoline in with summer fuel to prevent gelling , I would have to go get the book for the ratio.
 
adding gasoline (petrol) to Diesel fuel will sometimes cause the engine to detonate (and run with greatly reduced power) possibly damaging the engine.
My 1981 VW diesel manual also said to add gasoline to "winterize" the fuel. I tried it several times and it caused the engine to run so poorly that the car would only do about 15 miles per hour max.
Maybe if a smaller percentage of gasoline to Diesel were used, it might have the desired effect.
 
I cant find where it says to prevent gelling must have been an older book or in the dodge cummins book . It does say

Your diesel engine can run with up to 30% leaded or unleaded regular (not premium)gasoline mixed with Diesel fuel.

I certainly wouldn"t be running 30% myself. and they don"t say but may just be for emergencys? that being said I have run up to 10% gas in summer fuel myself quite a bit with some oil added for lubrication and never had any problems at all.

"gasoline is not loaded anymore "
did you mean leaded?
 
Thank you so much Bug,

Yes I realized my mistake when I red your answer. I mean ... Unleaded for sure.

I am pretty sorry, because I had a can with some gazoline Premium unleaded mixed with a little road diesel : I helped my sister who made the mistake to fill her car with gazoline instead of diesel... JJ
 
Hi Mark,

Thanks, Is the low speed of your engine could not be explaned by the wax in the fuel filter when previously using summer diesel during high frost ? JJ
