6 Myths & Phenomenal on Engine Performance & Lube Oil

It is rather common to hear motorists with relatively new cars (1 – 2 years old or cumulating some 20,000 to 25,000km mileage) commenting the followings:

1.   The performances of their cars are not as good as
      compared to first few months when they took delivery,

2.   Their newly changed lube oil tends to ‘blacken’ much
      faster than it was when their cars were a few months
      old.


Skeptics might argue that such comments are purely psychological while others might said the general wear and tear of the engines, gears and tyres played a part in it.

It is almost impossible to evaluate on the psychological aspect on point (1) above as it differs from one person to another.

As for the wear as tear reasoning, there are some truths for old cars with considerable mileage and are not properly maintained. However the same reasoning cannot be said for relatively new cars. With the present technologies on material science, car and engine designs, wear and tear on the contrary are very much controlled. Therefore, the reasoning of wear and tear is very much a myth. If the myth holds truth, the reputation of the car manufacturers would greatly be in question. In this aspect, the phenomenon as rebutted by skeptics remains unanswered.

 

 

Lube Oil Deterioration

The underlying fact is that car engine’s lubricating oil deteriorates over a period of running hours or mileage clocked. The entire lubricating system is dirtied due to the nature of combustion process. Combustion process produces kinetic energy to drive the engine pistons into millions of revolution to move the car, truck or to produce power in the case of power
generators. This results in the generation of enormous amount of heat, pressure, a fair amount of carbon residue (differs case by case with car/engine manufacturers), oxidation, by-products such as aldehydes, ketones, alcohols, carboxylic acids, anhydrides esters, ethers, as well as organo-nitrates, nitrate esters and some particles within the engine system.
In general, the lube oil within the engine system begins to deteriorate the moment the engine is in use through:

1.   The formation of carbon residue from the combustion,

2.   The formation of oxidation by-products,

3.   The ‘fall out’ of the lube oil additives,

4.   The heat generated from the combustion process, and

5.   The shearing force on the lube oil sustained from the
     revolution of the piston.


In short, above deterioration cause the formation of what is commonly known to the layman and industry as ‘sludge & gums’ within the lubricating system. In technically terms, the viscosity of the lube oil increases with the carbon residue and particles affecting the lubricity of the lube oil. The increase in viscosity of the lube oil increases the friction and load between the piston and the cylinder liners. This causes the engine to perform less than optimum and leads a reduction in power output.

To counter such effects, lube oil manufacturers are constantly developing better engine oil to satisfy the newer and more powerful engines. However they also realized that the efficiency of the lube oil is largely governed by the removal of the ‘sludge & gums’ within the engine lube oil system.

Conventional OEM filters with 30 microns size that are fitted in the cars performed rather satisfactorily in new cars/engines. However they are ineffectively in removing carbon residue and particles below 30 micron. Over a period of engine use, this carbon residue and particles thickens and become jell-like. These jelly-like sludge & gum are generally larger than 30 micron in size. Because of its jelly-like nature, they tend to coat and adhere on the outer surface of the lube oil filter media rendering instead of permeating into the deeper layer of the filter media. Very soon the entire surface area of the filter media will be coated with this jelly-like sludge & gum rendering the filter useless for its purpose. At this stage, additional introduction of carbon, particles and sludge formulation will not be trapped by the filter. It just re-circulates within the system and further accelerating the deterioration of the new lube oil and the engine fair wear and tear.

When this phenomenon extends over time, the sludge and gum layer will become more prominent and tends to build up at the lube oil sump of the engine. During routine servicing, used lube oil is drained off and replaced with new oil. However not 100% of the sludge & gum within the engine system is drained off together with the used oil. The reason is this jelly-like sludge & gum tends to adhere to the certain parts of the lubricating system particularly at the bottom and the walls of the engine sump. Therefore during routine lube oil change, a fair amount of used lube oil, sludge & gum still adheres on the surface of the engine sump. When new oil is introduced into the engine, it will rapidly be contaminated by this sludge & gum thereby causing the efficiency of the new oil to deteriorate rapidly. To the layman, the lube oil starts to ‘blackens’ very quickly after a new oil change.

This phenomenon is not present when the engine is new with less than 5000km to 10,000 mileages. In fact it is not uncommon to note that the visual conditions of the lube oil in a new engine to be fairly clean.

 
 

Ideal Engine Condition

To ensure that the engine performs at its peak or nearly as new condition, the most idea situation is to keep engine as clean as possible to the condition it was from day one. Shell Petroleum, one of the largest lube oil manufacturers in Europe, also echoes the same thing. Shell Petroleum in their Shell Helix Ultra lube oil brochure stated that:

“A cleaner engine is more efficient when it comes to acceleration and performance”.

Independent research conducted in Japan has shown that when engines are kept clean through periodic engine flushing and scheduled oil change, its conditions and performance after 2 to 3 years is 95% comparable to that of a brand new engine.

There are numerous engine flushes in the market. The question is which flushing chemical isthe most effective and does not harm the engine as well. Some engine flushes contain very strong industrial solvents that are toxic and flammable. Whilst they can be effective, they are also known to affect some engines, hoses and gaskets causing damages thus causing overheating and possibly seizure of the engine. This is because strongly solvents:

1.  Reacts with the rubber compound of the hoses and the
     engine gaskets causing them to ‘hardened’ and eventually
     become brittle and cracked up. When this happen, the
     engine lubricating system will start to leak and lose
     lubricating oil,

2.  Break down the sludge & gums into semi-solid mass
     which can block and choke the re-circulating pipes in the
     lubricating system causing starvation of lube oil resulting
     in overheating of the engine

 
 

Why use Engine Flush?

Over a period of time, sludge, gums and carbon deposits would have formed on the sump tank of the engine. These substances cause the engine oil to deteriorate rapidly affecting its performance and causing the engines to produce pollution and increasing it operating cost through consuming more fuel. Furthermore, these substances can cause the engine to increase its wear and tear hence increasing its maintenance cost.

 
 

The important points in considering and evaluating engines flush

There are currently many engine flushes in the market, which claim to have the similar efficiency. Listed below are the important points to consider when choosing an engine flush:

 
  • Is the product really efficient? Can its efficiency be visually and scientifically proven?
  • Will it lead to fuel efficiency say 8% to 15%?
  • Has it been tested by internationally recognized laboratory?
  • Will it damage engine and posses danger to the driver, passenger and pedestrians? ie. Will the chemical attack engine parts such as rubber hoses etc.
  • Will it cause the lubricants to coagulate into lumps and/or semi-solid particles choking the lube oil re-circulating system hence causing the engine to over heat and fail?
  • Is it environmentally friendly? Or does it contain strong industrial solvents and/or chemicals which itself is an industrial hazard not to mention some are toxic.
  • After flushing with engine oil, will it contribute further hazard during disposal? ie. fire and health hazard.
  • Does it have a pH near neutral (7)? Only product that does not contain strong chemicals has a pH near neutral.
  • Is it simple to use and administer?
  • Can it be used in all engines? ie. gasoline engine, diesel engines and LPG modified engines including power stations etc.?
  • Will it contribute not only to environment protection in
    reducing emission pollutant by 10%-20%?
  • Most important, it is economical?
 

Uniqueness of Miyabi Engine Flush

Miyabi Engine Flush is one such flush that meets all the above requirements. In fact, Miyabi Engine Flush is the only engine flush known to date to have a pH near 7. It is environmentally friendly that would not pose danger to marine & aquatic life if it is accidentally spilled (1:5000 ratio). Under the Material Safety Data Sheet (UN Chemical Class), its disposal method classed as water which means the product could safely be disposed off as if it is water. Refer to enclose MSDS.

 
 
 

How Miyabi Engine Flush™ works?

Miyabi Engine Flush™ is derived from the same technology and know-how from the successful Miyabi Oil Spill dispersants. It is formulated and enhanced specifically to remove the gum, sludge and particles within the combustion engine system.

It is non-toxic to aquatic and marine life. With a pH about 7 (almost neutral), it does not react with the mechanical parts rubber hoses or gaskets of the engine and its circulating system.

Miyabi Engine Flush™ with its oil-compatible ("lipophilic") properties acts on the jelly-like sludge and gum within the engine’s lube oil sump and its circulating system. When kinetic energy is added on the system (ie running the engine for about 10-15 minutes) the sludge and gum will soften and broken down into minute emulsified oil mixture as illustrated in Diagram 4 below. This emulsified oil/sluge mixture is eventually drained off from the engine system. What has happened is that the engine lubricating system has been cleansed properly.

Scientific Tests to evaluate efficiency of engine flush

There are 2 scientific tests available to evaluate the efficiency of engine flush, namely:

1. Viscosity Test (ASTM D445)

 
  • A sample of the lube oil is drawn from the engine before oil change.
  • Add engine flush in to the engine and the engine for about 15 to 20 minutes. Draw a sample of lube oil from the
    engine (at the same location as the first sample drawn) just before draining off the lube oil.
  • Send the 2 samples to a laboratory for viscosity analysis.
 
2. Total Sediment Filtration Test (IP 390 Modified)
 
  • A drop (2ml) of heated lube oil sample drawn from each of the 2 samples above is place onto a piece of pre-weight filter paper (or coffee filter paper).
  • Weight each of the filter paper.
  • The oil drop will enlarge outwards to form a circular shape.
  • Leave the filter paper to dry for 30 minutes.
  • Weight each of the filter paper.
  • Compare the colour of the 2 oil drop stains on the filter paper.
  • Calculate the nett weight difference of the 2 filter papers.
 
Enclosed is a test certificate by British Standards International (BSI) on the above test carried out. The test results shows that the lube oil sample after using Miyabi Engine Flush contains a lot of sludge tested under the Total Sediment Test and also the viscosity greatly increase as well.

This goes to prove that Miyabi Engine Flush was effective in removing the sludge and gum in the engine system and results in the increase of the viscosity and sludge levels.
 
 

Miyabi Engine Flush™ Field Test

A large scale field test was conducted in Japan in 2001 on 300 taxis.

The results are as follows:

Field Test -- Viscosity

 
 
 

Commentary of the Field Test Results:

1.  The average viscosity of the lube oil increases as the
     thick sludge and gums were dislodged and dispersed
     from the engine lubricating system after using Miyabi      Engine Flush™.

 
 

Can Miyabi Engine Flush™ be used on any type of engines?

the content is almost neutral in pH, non reactive and does not contain corrosive and/or reactive chemical ingredient, it can be used on any engines such as trucks, buses, generators and marine engines. There are no adverse reports on any engines using it.

Any precautions?

There are generally no special precautions other than the pre-existing engine conditions. Miyabi Engine Flush™ objectives are to clean and remove the sludge and gums that are present in the engine system so that the engine enjoys better fuel efficiency, performance and reduce maintenance costs.

For carbureted cars, engine tuning is required after using Miyabi Engine Flush™ to obtain the optimum benefits associated it. This is because the engine might have been tuned previously during the last oil change in accordance with its condition then.

For engine that has pre-existing defects, problems and/or damages that would have warrant repairs, the benefits described above when using Miyabi Engine Flush™ may not be apparent and/or absence depending on the severity of engine defects, problems and/or damages contained therein. Also, in older engine, there is a tenancy that the gasket which is due for replacement might have been ‘hardened and coasted’ with a layer of sludge. Miyabi Engine Flush™ would remove this layer of sludge content around the interface of the gasket and therefore in some cases, leaking of a small amount of oil from the gasket might be present. This is not to be mistaken that Miyabi Engine Flush™ has caused damage to the gasket. It is the gasket that is already damaged and needs replacement. This is absent in newer engines or engines which has their gasket replaced in accordance to the recommended service interval.
