Is there a specific diesel fuel additive for mercs? i was told there was such a thing and it gives extra lubrication tothe fuel system, pump, etc. Is there such a thing?

If that spooks you, then run about 10% or 20%biodiesel, which isveggie oil without the glycerin...

I run Power Servicesupplement in winter -- you can get it at Wal-Mart. It has a cetane booster, a lubricating factor and an anti-gel agent which is helpful during the cold weather.
Be careful adding vegoil of any type when the weather is below 45 degrees as it will lower the cloud point of your diesel fuel and make starting your engine very difficult. It can also clog your filters, IP and injectors thereby crippling your engine.

worth a read if your in the mood for something slightly technical with your morning tea.

I use an additive that only boosts the cetane number of the fuel. There is no need what so ever to worry about the lubricity of the fuel.
8+ CETANE IMPROVER
Fuel PowerIncrease Cetane - Increase Efficiency
Diesel engines function on the principle of Auto Ignition. The range of temperatures varies from 410ºF to over 1040ºF, this wide range is due to lower cetane numbers. 8 Plus Cetane Improver will raise the cetane level of your fuel providing faster starting, reduced engine noise, reduced smoke and particulates, and increased power and acceleration.

During the summer I use 100% veg oil. In the winter I use 90%veg. ( I live on the Pacific North West, coldest so far this winter whereI livewas around 20 degrees F.) I installed mercedessource.com modules, using the original fuel tank as the only fuel source. Granted, it's still experimental, especially atsujch ahigh percentage of veg oil, but so far the systemhas performed flawlessly.

I STRONGLY suggest you use a two tank system and stop running the veg oil with a single tank "conversion". The cold oil going into the engine before it's warm will cause wear in the injection pump, coke the injectors and damage the piston rings as it builds up a gunk on everything.

I also installed a 2 tank system in my creampuff 1990 Jetta ecodiesel, and drove it for over 35,000 miles, finally understanding that constantly heating and cooling veg oil is a major problem in itself, which eventually causes a green substance to form in the tank, etc..... and it's little more than a Rube Goldbery device..
Yet I do preheat the veg oil. It's first preheated veg oil in the sump chamber. I replaced the 5/16" fuel line coming from the tank, to a 1/2" fuel line which allows even near frozen veg oil to gravity flow into the heated fuel sump chamber, then into a clear filter, then into the electric fuel boost pump. then into another clear filter, then into a stanadyne water separator filter, then into another gp heater, then into the IP...
Still, with all of that...The veg oil only needs heating in order to get it to flow, and to extend the life of the water separator filter. Grantedf, the first few minutes before the engine reaches operating temp, the oil should be heated at the fuel injection lines...That can be done with in line heaters.
But after the engine is at operating temp, the natural heat, measureed with an infra temp gauge, at the outside of the IP is 120 degrees, and the natural temp of the injection fuel lines is just about 200 degrees. That means any fuel, including Veg oil, is instantly heated to 120 at the IP and to 200 degrees when it enters the fuel injection lines ...
So, IMHO, except to get and keep the fuel flowing, and to extend the life of the water separator filter, the need to preheat veg oil, other than the first few minutes until the engine heats up ( which is easity done by in line heaters ) ... Preheating veg oil after the engine is warm is a myth, probably created by those who sell heated 2 tank systems, and unnecessary unless there is a fear that it gets so cold that the veg oil solidifies.
That problelm can easily be addressed by adding a small 5 gallon marine tank in thetrunkfilled with diesel...plus. asoliniod to switch fromveg oil to diesel ... and in my case,simplyflip on the return fuel switch on my dash... which will sendheated fuel to the tank and quicklyliquidize it.
But even with that system, the purging is unnecessary provided one has in fuel line injection heaters... which can be bought from mobetta at schumanautomotives.com for $25.00.
