Tractor/diesel problem

Johnny welder

I have a New Holland T5060,2008 with 2800 hours.
Recently it has become slow to start and we replaced a few bits to see if we could improve it .We put in a new lift pump,changed filters and checked all sensors but nothing changed.A mechanic in England who works for New Holland advised to put a gallon and a half of engine oil in the diesel tank to lubricate the fuel system,we did and there was a hugh improvement.On the next fill of diesel we did not put in any oil and it was slow to start again,so once again we added engine oil and it started ok.It appears that the new diesel lacks enough lubrication.I am wondering if there is any other solution to the engine oil,on researching on the internet I came accross upper cylinder lubricant and wonder would this help.
I would appreciate any views.By the way the oil mix does not make the engine smokey and it runs perfectly smooth with perfect power.

Try red diesel instead of green.

There's talk of the new diesel causing problems with fuel pumps also on new machines and fuel lines on older machines.
I'm lead to believe that this is from the sulphur that was removed from the diesel and it tries to get it back naturally through rubber seals in fuel lines and newer fuel pumps. I've heard of a few pumps that had to be changed and this was the reason given.

I had to send off the injector pump off my tractor last Saturday. It had ceased up three veins and one vein had sheared off. This was due to dirty diesel and now i have to send off injectors tomorrow because there not working been a whole week without a tractor

It appears that problems were created when the sulpher was removed as this provided lubrication,an alternative was added to the diesel but is it as good.
Is red diesel any better or is it just a different dye????
Is red only available in the Uk regions now??

I heard a few local lads are putting the injector cleaner for cars into their tractors every few fills to keep them clean.i know a few mechanics and they tell me something strange is afoot as the number of injector pumps that are failing in all vehs (cars/trucks/tractors)in the area is serious.

the man that did the pump would be a well known for doing pumps and injectors and he showed me a a few pumps that had acid put in the diesil,( bag of can in his opinion) the pumps would be in bits. Whats vexing me is that we only did the injectors two months ago and now have to do em again

Our theory is that there is a lot of laundered diesel floating about in branded filling stations.

Ya but that should only be in the white (road) diesel. Unless Whelan's neighbours are using green diesel to dump the dye and whatever else they use to launder diesel.

WTF revenue can't do away with green diesel, and just give farmer's a rebate, and all this sh1te would stop.

If that was me I would be bringing that to the attention of my oil supplier.

Do you have a steel or plastic storage tank?

That would be the proper solution alright

steel tank. Im going to change it if i can

If the tank was old or rusted on the inside, little bits could be getting into your engine through the diesel. Plastic tanks are better plus less chance of condensation forming and adding water to the diesel

I had fierce hardship with my machines when that diesel was first introduced.. used to be changing filters every few weeks! Changed to a plastic tank and added a filter to the tank, there was a massive difference.. The finest filter I have was 20 micron so I put a 50 micron one in the tank and all the machinery seem to be running a bell if a lot better.. several lads told me to change supplier and see what the difference is so I am going to do that for my next fill fore the craic.

Try a few cans of heating diesel rather than agricultural diesel and see will that make any difference, as far as I know heating diesel still has the sulphur in it

I have done work indirectly with some diesel pump manufacturers. All these new common rail systems are far less tolerant to dirt than the older machines. Machined tolerances and clearances are a lot tighter, to achieve the high level of tuning required to meet emission requirements. I've heard it said also that even in places like south america pumps are machined differently to handle the less cleaner local diesel.
Put on a ultra fine filter and get a new clean tank. We had an old steel tank here and it broke our hearts for a few months with tractor cutting out.

We use dipethane with every fill of our tractor (T5040). Last summer we had some issues with the tractor - on a low rev, you could hear it rising and falling. Probably due to dirty diesel or the new diesel stripping dirt from the tank and fuel lines. After the first fill with dipethane, it went away. Fuel economy is noticably improved and the tractor runs much smoother. The dipethane pays for itself, although we wouldn't be using that much diesel putting about 400 hours per year on the tractor.

I wouldn't chance putting engine oil into that new of a tractor as it would void any warranty or any goodwill that you would be likely to get if you had problems.

Also, the small inline diesel filter needs to be changed about every 200 hours. At €3 each, it's not going to break the bank!

And don't get home heating kero instead .... Probably wouldn't end well

Johnny welder

Home heating oil(kero) is not recommended in diesel as it does not contain any lubricants,diesel does.Kero has a much lower flash point of 40 degrees in comparison to diesel at 80 degrees so it would start easier if mixed with diesel but would cause problems to the fuel system,pump,injectors,cylinders,valves etc..
All fuel filters are changed on the tractor including the diesel tank and dirt is definetly ruled out by all who have looked at it.
Many guys that bought new tractors near me have been advised to put an additive in the diesel to aid lubrication,from a special 1 to simply adding engine oil,so it appears that the garages are finding problems in relation to diesel not containing enough lubricants since the sulpher was removed as this was providing the required lubrication in the fuel system.

Had three native Irish ladies run out of diesel outside the house in a shook Hiace early one Sunday morning, had no diesel so gave them a gallon of kerosene and it started up a bit Smokey , but it got rid of them:D

Oil Will

Hi,

I have worked in the lubricants industry for 20 years and would not recommend you put engine oil or any other mineral oil into your diesel. If you wan to add a lubricant add two stroke oil, semi-synthetic preferably this is designed to lubricate and burn off with the fuel. The engine oil is designed to resist burning off. Also the new diesel has a small percentage of biodiesel added to it this causes its own problems especially in storage tanks. In just 6 weeks the biodiesel will start to separate from the standard diesel and search out any moisture in your tank. This can lead to diesel bugs and other nasties growing in the oil. Add 250ml of Star Tron to your 1000lt tank and it will protect your diesel for up to 18 months. You can also add this to old diesel to bring it back to life.
