Oil Management System for Diesel Engines

03/11/2010 3:52 AM

Dear All,

I came across an oil management system for diesel engine aimed at reducing the overall operational cost and also extending the life span of the engine for its improved lubrication and cooling effects on the engines. Below is the brief description of how it works;

system removes a small amount of used engine oil form the sump and blends it with diesel fuel to be burned during combustion. The used oil is then replaced with an equal amount of fresh oil from a make-up tank, extending oil and filter use (up to 10,000hrs between oil changes and 1,000hrs between filter changes) thereby reducing the total operational cost. It is not a replacement for the filtration system – it improves and works in conjunction with the system.

My concerns are as follows;

1. For the pistons, how will the diesel mixed with the engine affect the pistons and the combustion chamber as the octane rating have changed due to the added engine oil.

2. How will it affect the engine emissions as I suspect the Combustion byproducts will change.

Let me please share your views on it.

Thanks

Hi Enb,

This is not a new ploy and neither is a good one;OK so by removing a 'small volume' of engine oil from the sump on a continuous it extends the oil change interval. Well if you removed enough you would never need to do an oil change at all!

As far as the pistons/rings etc are concerned a small amount 1-2% of fuel volume will burn without trace and the conditions in the combustion chamber will be unaltered. I will place one caveat on this statement however and that would be for this arrangement to coincide with a fully loaded engine operating at full temperature otherwise there could be a buildup of incompletely burnt residues over time.

The real concern is in terms of the effects of 'contaminated fuel',being the result of the introduction the used lube oil,on the injection system. Obviously the blending point would have to be prior to the fuel filters otherwise you are staring disaster in the face, even so there are acidic products and other undesirable trace chemicals in the lube oil which will have an uncertain effect upon the fine tolerances in the fuel pump and injectors.

Given that you will be buying more lube oil than otherwise and replacing fuel filters much more frequently with the possibility of losing injection pump/injector efficiency prematurely I would not advocate this practice.

Stick to the manufacturers' recommended oil change intervals otherwise you are very much 'out on a limb' and potentially exposing your engine to an uncertain future.

Good luck,

Massey

Hi Massey,

Thanks for the response, you have actually hit my concerns.

Br,

The best thing you can do for an engines life is use a system like the amsoil bypass filtration system. There are a few other systems like it, as well. It also takes oil from the sump, but runs it through a very effective oil filter, basically a roll of paper towels. The wood fibers in the towels increase in strength with oil, so they wont fall apart. the oil then goes back into the engine. I think the army is now doing 100,000 mile oil changes, or somthing crazy like that, because the extra filtration keeps the oil like new. Diesel will still work its way in to some oil systems, so inexpensive used oil analysis should be done a few times before relying on 100,000 between changes. Also, fuel from the local pump is usually only filtered to about 20 micron. Filtering your fuel down to 5 micron, or even less, will greatly increase engine life.

search bypass oil filtration, and you find several suppliers. They are great systems

While Amsoil does make a very fine product, as does the majority of by-pass filtration manufacturers, the possibility that a portion of the oil is never filtered by the by-pass system still can be assumed. Adding a magnetic charge on the OEM side (oil filters), along with the by-pass system, will prove to be highly beneficial.

The advantage is that it works on any spin-on filter

Good Luck
