UniGlide "Vitamins for Fuel"- The Technical Facts.
Octane is the measure of a Fuel's resistance to Knock, Ping, or explosion.
For an engine to work at optimum efficiency, the fuel must burn in a controlled fashion and not explode.
Even though this burning takes place in a very short period of time, in the order of microseconds, it has a major effect on engine performance.
Factors such as the "burnability", of the fuel, the ignition timing and the altitude all playa part in optimizing the burning of fuel in the combustion chamber.
Spark timing is regulated to begin before the piston reaches TDC, (Top Dead Center) in order that this burning may have full expansion effect only once the piston is just past TDC.
Over advancing the timing causes the 'pinging' sound, because the burning is taking place before the piston has reached TDC.
Higher altitudes mean lower atmospheric pressure, and thus less oxygen is available to support the burning process.
This reduces the engine performance and also the octane requirement.
Fuel companies add "Anti-knock" chemical additives to the fuel, to help control the burning, and make it happen quicker, more efficiently at the optimum moment.
These are also referred to as octane boosters.
Lead compounds are the most performance and cost effective octane boosters available, however, because lead is poisonous, most first world countries have banned them.
Thus the "unleaded" Fuels.
Octane is measured by different methods in different countries.
Some use RON (Research Octane Number), others use MON (Motor Octane Number).
In the USA they use the average of the two, and gasoline is sold in 3 different octane grades, by this measurement, namely:
87; 89 & 92 Octane.
This is well controlled, and the Octane is monitored by inspectors appointed to take random samples from Fuel Stations.
Starting in 2002; California is banning the use of MTBE, as an octane booster, and the Fuel Companies will be supplying 86; 88; & 91 octane gasoline at the gas stations.
In South Africa, the octane is measured by RON, and the octane rating of 93 is supplied on the high yield, most of which is at an altitude of 1700 meters above sea level.
Coastal petrol is supplied at 98 octane, to cope with the extra oxygen at or close to sea level. However, the quality of the Petrol in SA is not monitored, and the octane rating is often subject to question, particularly in outlying areas, where the fuels are handled / pumped into different containers / tanks during transport to end-user process.
Also, SA high yield fuel is laced with alcohol, which alters the burning characteristics, and makes the petrol more likely to absorb moisture, which will increase the risk of corrosion.
Alcohol also reduces the fuels ability to lubricate valve gear.
Australian petrol has a high aromatic content, wmcn makes it more volatile, reduces shelf life due to evaporation, and it can cause problems with rough idling and other maladies.
Some of the less developed countries have very poor quality fuels available to the general public.
Despite what consumers may be told by the oil companies, there are enough reasons to doubt the quality of fuels, and the octane ratings of the fuels that consumers pump into their vehicles every day, in most countries.
Un-leaded fuels do not have the lubricity of leaded fuels, and will cause valve seats to wear, or recede into the cylinder head.
This in turn reduces the rocker / cam to valve stem clearance, requiring more frequent adjustment of this clearance, which relates to higher maintenance costs.
Insufficient clearance can result in burnt valves, and the associated repair costs.
SASOL in South Africa, has developed their "Dual Fuel" in an attempt to address this problem. Dual Fuel, contains magnesium as an anti-knock compound, and it is certainly better than other un-leaded fuels.
However, it still contains alcohol, which can cause problems, and it is not available in the coastal areas.
How can UniQlide Fuel Tablets help?
1) Fuel Tablets Increase the Octane of whatever fuel you might use;
The increase depends on the method of octane measurement, and the octane level.
With the American octane ratings, expect an increase of one to four numbers.
ego If you add a tablet to 75 octane gasoline, you will get an increase of 4 numbers and have 79 octane fuel.
If you treat 87 octane you will get close to 89 octane, at the recommended treat ratio of one tablet per 60 litres.
2) The more "Vitamins for Fuel" you add the higher the octane you will get - up to a point!
Double dosing will increase the octane around one to two numbers in the American system. Adding a 3rd tablet however, will have little appreciable effect, and will be a waste of money.
3) Because "Vitamins for Fuel" cleans the fuel system from tank to combustion chamber, it reduces "Octane Appetite" - (see separate explanation)
Keeping the combustion chamber clean will mean that the lowest octane applicable to that compression ratio can be safely used.
Even engines with heavy combustion chamber deposits will have burned themselves clean after 4 "Vitamins for Fuel" treatments.
4) Uniglide "Vitamins for Fuel" contains a Combustion Catalyst, which optimizes the burning of the fuel.
This releases more of the latent energy in the' fuel, and converts into mechanical energy in the form of pressure on the top of the piston.
This means more power output.
Because or the Increased power, the same work can be done with less throttle opening, which must result in Reduced Fuel Consumption.
5) Because the Combustion Catalyst helps the fuel burn more completely, there will be less unburnt fuel in the exhaust gasses.
This unburnt fuel is measured as hydrocarbons (HC) by an exhaust gas analyzer instrument, and these hydrocarbons will be reduced by between 25 % and 50%.
This reduction in HC, will depend on factors such as combustion chamber design, fuel injection vs. carburetor, engine temperature, engine speed, and others.
Diesel engines, are especially prone to emitting particles and smoke with the exhaust gasses. These emissions have been shown to be carcinogenic, and can be measured by an "Opacitor" or smoke meter.
Because the fuel burns more completely, the smoke and particles are also reduced substantially.
6) Because of the more complete combustion, the Carbon Monoxide (CO), and Nitrous Oxide (NOX) content of the exhaust gasses is also reduced.
This can also be measured by a 4-gas analyzer used in conjunction with all the "Smog Check" dynamometers.
CO and NOX levels will be reduced by over 70% in most cases.
7) Because of the reduction in noxious gases, the life of Catalytic Converter is extended.
8) Because of the chemical cleaning action of "Vitamins for Fuel", the life of fuel injectors and injection pumps is extended.
9) Uniglide "Vitamins for Fuel" also contain a fully tested Lead Substitute, which lubricates valve stems, valve guides and seats.
10) Older engines which were designed to run on leaded fuel, may suffer from "Valve Seat Recession", when run on un-leaded gasoline.
Uniglide "Vitamins for Fuel" reduces valve seat recession, to almost the same level as lead.
11) The Chemistry in Uniglide "Vitamins for Fuel" has been thoroughly tested by the Society of Automotive Engineers (SAE) in the USA, and by the TUV in Germany, Uniglide "Vitamins for Fuel" are registered with the Environmental Protection Agency (EPA) of the USA.
12) "Vitamins for Fuel" is completely safe to use with ANY hydrocarbon fuel, including
leaded or un-leaded Petrol, Diesel, Methanol, Racing Fuel, Avgas, and Parraffin.
13) Uniglide Fuel Tablets dissolve completely within a few hours, and will not clog injectors or filters.
They have a shelf life of up to 5 years, when properly stored, and will not melt in hot weather.
13 excellent reasons for you to use Uniglide "Vitamins for Fuel" in all your vehicles, at every fill up.
