ER is a pure concentrate that is not diluted with oil. ER is a liquied chemical formula designed to be added to your existing oil to improve and protect moving metal parts. ER is activated by heat and friction to protect against wear created by the moving parts in your engine. ER is not a typical oil additive, but the first "true" and "original" Antifriction Metal Conditioner. ER significantly smooths rough surfaces of metal by modifying the first few microns of the metal surface. This unique chemical process results in stronger and smoother metal partsWhen ER is added, and friction and wear are reduced in any vehicle or equipment that has moving parts, any of the following may occur: increased performance, improved combustion efficiency, increased fuel economy, reduced operating temperatures, quieter operation, reduced oil consumption, extended oil life, easier cold starts and extended vehicle life.

Nulon Extreme Pressure Anti-Seize Lubricant is a complex bentone based lubricating paste containing a high percentage of polytetrafluoroethylene (PTFE). Nulon L90 provides extremely high film strength and adhesion, protecting against initial start-up damage of machinery even after long periods of lay-up. Nulon L90 provides long-term lubrication of components that are otherwise difficult or impossible to lubricate after initial assembly. Most chemicals, solvents and corrosive agents do not affect Nulon L90. L90 does not dry or harden with age and offers performance over a wide temperature range. L90 protects exposed components against rust during lay-up. L90 permits more even torque pressures and faster breakouts of threads, joints, flanges and gaskets.

Benefits:

  • Minimises initial start-up damage
  • Seals gasket surfaces without adhering
  • Seals threads up to 8mm diameter
  • Reduces possibility of seizing
  • Reduces wear and friction
  • Protects against corrosion
  • Resists water wash out
  • Offers a high degree of residual lubrication

Nulon Trade Strength Anti-Wear Engine Treatment

is specifically formulated for use in all four-stroke petrol, rotary, *diesel and LP gas engines. Nulon Trade Strength Anti-Wear Engine Treatment is also recommended for use in all high performance, competition and turbo-charged engines. Anti-Wear Engine Treatment is a special blend of high-grade carrier oils, Zonyl and other performance anti-friction and anti-wear additives. This unique formulation has been proven, in industry standard tests, to improve anti-wear characteristics of typical engine oil by as much as 350%.

 

Nulon Trade Strength Anti-Wear Engine Treatment contains Zonyl ultra-fine particles of PTFE, which has the lowest co-efficient of friction known to science. Few of us these days have time to allow our engines to warm up before driving. We simply start them and drive. It is a known fact that 80% of engine wear occurs during start-up and until the engine reaches operating temperature. Nulon's unique engine anti-wear formulation helps to protect against wear during these critical high wear periods. While there have been many advances in the performance of engine oils in recent years, the demands placed on the engine oil have also increased dramatically. Vastly increased power output, higher operating temperatures and extended oil change intervals all contribute to greater levels of oxidation and nitration, the very things that limit the oil's effective service life.

Benefits:

  • Improves the anti-seize and anti-wear properties of engine oil.
  • Safe to use in all engines using mineral or synthetic oils.
  • Reduces engine noise.
  • Helps reduce start-up wear.
  • Boosts the additive package of new oil.

Nulon Trade Strength Oil System Cleaner

is formulated to safely dissolve and dislodge sludge, carbon deposits and other harmful combustion by-products that accumulate within an engine's lubrication system during normal operation.

Unleaded petrol, very much higher operating temperatures, increased power output and extended oil change intervals all contribute to oxidation and sludge formation. As a result, engine oils have more to cope with and are under much more stress than ever before. Built-up engine deposits are the greatest cause of failure in modern engines.

Environmental pressure and consumer demand have brought about extended oil change intervals. Manufacturer recommended oil change intervals are for vehicles that operate under ideal conditions. Few vehicles operate under such conditions, which means that the oil's additives degrade quicker, hence the oil should be changed more frequently. However, this does not happen and increased sludge and carbon forms as a result.

It makes absolutely no sense to add clean oil to a dirty engine. When added to the crankcase prior to an oil and filter change, Nulon Trade Strength Oil System Cleaner greatly assists in ridding the engine of potentially damaging contaminants. Nulon Oil System Cleaner also helps to free sticky hydraulic valve lifters. Thermal efficiency of the engine is also improved by ridding the engine of insulating sludge build-up. Oil System Cleaner provides a cleaner environment for fresh oil to operate in, so the detergent, dispersant and anti-oxidant additives in the new oil are not depleted as quickly.

Caution
Do not use this product in an engine that is known to have excessive sludge and carbon build-up. Carbon particles flushed from the top of the engine into the sump may not drain out. In such cases the oil pick-up will be heavily contaminated and picking up the extra loose carbon which may block the pick-up completely.

Benefits:

  • Dissolves sludge in oil strainer screens
  • Safely cleans soft carbon and sludge
  • Helps free-up sticky piston rings
  • Provides a cleaner environment for new engine oil, when used as directed
  • New oil stays cleaner for longer

Features:

  • Suitable for petrol, gas and diesel engines
  • Safe to use in older engines
  • Will not harm oil seals or gaskets

Nulon Engine Stop Leak

is a result of the most advanced technology available in the control of engine oil leaks due to the failure of oil seals, particularly those of the elastomer type. Most modern engines use this material as the basis of their "rear main" and "timing cover" seals. These seals are difficult to replace and in many instances require engine removal, or at least considerable labour costs, to install replacements. ESL also effectively promotes better sealing of valve stem seals. ESL is safe to use in all petrol, diesel and LPG engines.

With time and heat seals become hard and lose their flexibility. Proprietary additives in ESL react with the seal material to soften the seal so that it regains elasticity and is again able to perform its function of sealing.

Nulon ESL is unique in that it serves two distinct purposes. To our knowledge, no other product available controls "oil leaks" and "oil burning" as effectively as ESL. If an engine is worn enough for seals to be worn, hardened or leaking, chances are the piston rings are not functioning correctly, consequently allowing oil burning/consumption. Nulon ESL is unique in that it has the ability to restore the sealing function of piston rings. This reduces oil burning and exhaust smoke.

Nulon ESL can be used safely in all overhead cam and multi-valve engines. Unlike many stop-leak and stop-smoke products, Nulon ESL is not an oil thickener. It can be safely used in engines that require low-viscosity oils, e.g. SAE 5W-30.

Benefits:

  • Reduced oil leaks
  • Improved engine efficiency
  • Reduced exhaust smoke
  • Improved cylinder compression
  • Reduced oil consumption
  • Prolonged engine life

Nulon Worn Engine Treatment

is especially formulated for use in all four-stroke petrol, *diesel, rotary and LP gas engines that display definite wear characteristics such as fuming, bearing or valve train noise, piston slap, piston wrist pin noise and poor performance due to general mechanical wear.

Nulon E10 contains PTFE and other performance additives to reduce friction, which in turn slows down the rate of wear within an engine. It is important to understand that the more worn an engine becomes, the faster the rate of wear.

Polytetrafluoroethylene (PTFE), the primary ingredient in Nulon E10, is a solid material that exhibits the lowest co-efficient of friction known to science. Nulon E10 contains particles of PTFE that are minute in size and spheroid in shape. These tiny particles circulate with the engine oil and act as tiny plastic fluoropolymer ball bearings between the wear surfaces.

Benefits:

  • Reduced wear
  • Reduced exhaust emission
  • Extended engine life
  • Increased cylinder compressions
  • Increased power
  • Reduced fuel consumption
  • Quieter, smoother engine

Nulon Performance Engine Treatment

is specifically formulated for use in all four-stroke petrol (gasoline), rotary, *diesel and LP gas engines that are considered to be in good mechanical order. Nulon E20 is also recommended for use in all high-performance, competition and turbo-charged engines. Nulon E20 is a special blend of high-grade carrier oils, Polytetrafluoroethylene (PTFE) and other performance anti-friction, anti-wear and anti-corrosion additives.

When added to mineral or synthetic engine lubricating oils Nulon E20 cleans all friction surfaces, removing carbon, varnish and sludge deposits, dispersing them in the oil for entrapment by the oil filter.

Nulon E20 contains PTFE particles ranging from sub-micron in size up to several microns. The sub-micron particles, over a period of time, will impregnate the friction surfaces of the engine. The larger particles are circulated by the engine oil and provide an extremely low friction barrier between wear surfaces. To retain the impregnated residual coating of PTFE on all friction surfaces it is important to treat the engine with E20 at each oil change. While E20 provides the optimum engine protection, it is not as cost effective as Nulon E30 over a period of time; however, if an engine is operated under arduous conditions Nulon E20 cannot be surpassed in the level of protection it offers.

* In larger diesel engines it is more economical to use Nulon HP Diesel Engine Treatment

Nulon Engine Oil Flush

is formulated to dissolve and dislodge harmful sludge, dirt, varnish and other contaminants that accumulate within an engine's lubrication system during normal operation.

Although modern engines are cleaner from an environmental aspect, all the pollutants of engine combustion previously released to the atmosphere are now recirculated within the engine. Consequently, lubricating oils have a much more difficult task in cleaning and suspending all of these additional contaminants.

When added to the crankcase oil prior to an oil and filter change, Nulon Engine Oil Flush greatly assists in ridding the engine of potentially damaging contaminants. Nulon Engine Oil Flush also frees sticky valves and hydraulic lifters. Thermal efficiency of the engine is also improved by ridding the engine of insulating sludge build-up. EOF provides a cleaner environment for fresh oil to operate, so the detergent dispersant and anti-oxidant additives in the new oil are not depleted as quickly.

Benefits:

  • Cleans all lubricated components
  • Reduces sludge, varnish and dirt contaminants
  • Frees sticky valves and hydraulic lifters
  • Improves overall engine efficiency
  • Extends the service life of new oil
  • Reduces the possibility of oil galleys being blocked, thus reducing the possibility of engine failure

Features:

  • Nulon Engine Oil Flush is extremely simple to use and improves the environment in which lubricating oil operates. EOF is suitable for use with all synthetic and mineral oils
  • Suitable for petrol, gas and diesel engines
  • Safe to use in older engines
  • Will not harm oil seals or gaskets

Nulon Long Term Engine Treatment

is the ultimate in long-term, low-cost engine protection and friction reduction for petrol engines. Nulon E30 contains ultra-fine particles of Polytetrafluoroethylene (PTFE), which has the lowest co-efficient of friction known to science.

This unique formulation is blended with high-grade carrier oils and other proprietary performance additives. The end result is a product which, when used only once, will provide a residual low friction surface on all moving parts that will last up to 80,000 km (50,000 miles).

Q. How does it bond?
A. Friction and pressure generated under normal operating conditions are sufficient to mechanically bond the sub-micron particles of PTFE to all engine friction surfaces.

Nulon E30 is extremely cost efficient as most oil additives have to be added to the engine oil with each service, whereas Nulon E30 is a once off treatment every 80,000 kilometres (50,000 miles). Rigorous field-testing has proven the long-lasting residual protection of Nulon E30.

Note 1. The long-term residual benefits are only attainable in petrol (gasoline) powered engines.

Note 2. Nulon E30 is recommended for engines considered to be mechanically sound.

Benefits:

  •  Lasts up to 80,000 kilometres (50,000 miles).
  •  Reduces cold start-up damage as the PTFE coating provides adequate lubrication until oil pressure is attained.
  • Extends engine life.
  • Promotes a quieter, smoother engine.
  • Improves fuel consumption.
  • Reduces engine temperature.
  • Is cost efficient.

Nulon Stop Smoke

has been specifically formulated to reduce exhaust smoke caused by burning oil. The two most common causes of oil burning are worn piston rings and worn and hard valve stem seals. Both are associated with normal wear and tear over an extended period of time. With stricter controls on exhaust emissions being imposed recently, motor vehicle owners have to be particularly aware of visible smoke.

Nulon Stop Smoke is a state-of-the-art, sheer stable, long chain polymer which, when used according to the directions, increases the viscosity of the parent motor oil. The resultant increase in viscosity of the oil simply makes it more difficult for the oil to flow past the piston rings or the valve stem seals into the combustion chamber where, of course, it is burnt.

Nulon Stop Smoke is extremely sheer stable which means it does not lose its viscosity at elevated operating temperatures � a common symptom in worn engines.

Increasing the viscosity of the oil has the benefit of reducing undesirable engine noises so typical of worn engines, such as noisy timing chains, piston slap and gudgeon noise.

The special long chain polymer technology used in the formulation of Nulon Stop Smoke is long lasting, which means it lasts the life of good quality oil, unlike many competitive products.

Nulon Stop Smoke represents excellent value for money as it is probably the largest container on the market and for typical four cylinder engines half of one bottle is adequate treatment.

Nulon Stop Smoke is suitable for use in petrol, diesel and LP gas engines. The long chain polymer viscosity improving characteristics ensure an improved seal between pistons, rings and cylinder walls, which produces optimum cylinder pressures.

Benefits:

  • Reduced exhaust smoke
  • Reduced oil loss and burning
  • Reduced fouling of spark plugs
  • Boosts oil pressure
  • Boosts cylinder compression
  • Quietens engine noise

Note: Nulon Stop Smoke is formulated with the prime purpose of stopping exhaust smoke caused by burning oil.

Nulon E10 Worn Engine Treatment should be used to reduce wear and it is compatible with Nulon Stop Smoke.

Nulon Engine Stop Leak should be used where leaks are the prime concern. It is also compatible with Nulon Stop Smoke.

Nulon Diesel Engine Treatment

has been formulated to cater specifically to the demands of today's high-performance diesel-powered engines. Extended oil change intervals, heavier loads, turbo-chargers and higher sustained speed all place enormous strains on today's diesel engines. Modern lubricants have to work harder than ever before to maintain a lubricating film of oil between wearing parts.

When added to conventional lubricants on a regular basis Nulon HP will offer the highest degree of protection available for all forms of diesel-powered machinery. HP has been designed with the large fleet operator in mind. It is economical and easy to use. Some HP applications are:

  • Trucking
  • Auxiliary power generators
  • Farming
  • Diesel-powered pumps
  • Earthmoving
  • Mining
  • Marine

Nulon HP enhances the lubricating qualities of all motor oils and reduces metal-to-metal contact. It is fully compatible with all mineral based and synthetic brands. HP is suitable for use with any oil filter rated in excess of 5 microns. HP is a complex formulation based on sub-micron particles of Polytetrafluoroethylene (PTFE), high-grade carrier lubricants complemented by other anti-wear, anti-friction and anti-oxidant additives. This whole package, when added to conventional lubricants, ensures minimum wear and scuffing resulting from high speeds and loads. Nulon HP, because of its superior lubricating qualities, helps maintain the integrity of oils. Regular use will minimise wear metals present in the oil. HP offers lubricating protection up to temperatures far in excess of normal oils. This is particularly important in terms of protecting turbo-charged vehicles. Nulon HP has an operating temperature range of -15�C to 250�C. (The minimum operating temperature may vary outside Australia.)

Benefits:

  • Increased power
  • Reduced friction
  • Reduced wear
  • Reduced fuel consumption
  • Reduced maintenance costs
  • Corrosion protection
  • Reduced oil temperature
  • Increased cylinder pressures
  • Increased engine life
  • Reduced downtime

Nulon Lifter-Free and Tune-Up

is formulated to harmlessly dissolve and dislodge harmful varnish and carbon deposits that accumulate within and around hydraulic lifters and cam followers.

Hydraulic lifter noise can be caused by several different factors:

  1. Mechanical damage to camshaft lobe and/or lifter
  2. Broken parts within the lifter e.g. relief valve spring
  3. Hard carbon particles blocking relief or delivery ports
  4. Sludge, wax or varnish deposits causing a sticky lifter

Nulon Lifter-Free and Tune-Up can be used to remedy causes 3 & 4. Replacement of components is the only remedy for causes 1 & 2.

Nulon Lifter-Free & Tune-Up can be used as an inexpensive method of diagnosing the cause of lifter noise. Simply add a bottle of product to the engine oil. If the noise has not disappeared after 14 days or 500 km, it can be assumed that previous mechanical damage has caused the lifter noise, or the problem could be due to low oil pressure, or insufficient oil volume. If it is established that the oil supply and pressure are adequate, the lifters should then be removed, inspected and replaced accordingly. Inspection of the camshaft lobes should be carried out at the same time.

Lifter noise is often caused by poor maintenance, i.e. not changing oil at the correct intervals. As the oil oxidises and forms hard carbon deposits, particles of the carbon break away and are carried into the lifter, where they accumulate and restrict oil flow. Poor servicing also contributes to the formation of varnish, which reduces tolerances and causes the lifter to stick. While Lifter-Free & Tune-Up will resolve these problems, one should not ignore the damage that these deposits cause elsewhere in the engine. Care should be exercised in establishing suitable oil change intervals. At the same time it is good practice to always flush the engine prior to oil and filter change to help rid the system of sludge and carbon. Nulon's Engine Oil Flush is formulated specifically for this purpose.

The use of high viscosity engine oils will contribute to lifter noise as it reduces the flow of oil through the lifter and takes longer to pump up initially. Reduced flow means more opportunity for particles to settle in the lifter. High viscosity oils generally oxidise more readily and produce more carbon. This is because the thicker oil takes longer to drain away from the top of the cylinder head (the hottest lubricated part of the engine). Generally speaking, high viscosity engine oils take longer to drain to the sump for cooling and longer to circulate; hence they do not carry away heat as quickly. This contributes to accelerated oxidation and carbon and sludge formation.

Benefits:

  • Quietens noisy hydraulic lifters / cam followers
  • Removes sludge and soft carbon
  • Cleans oil galleys in hydraulic lifters
  • Frees-up sticky lifters
  • Will not affect oil viscosity

Features:

  • Simple to use
  • Suitable for petrol, gas and diesel engines
  • Safe to use in older engines
  • Will not harm oil seals or gaskets
  • Can be safely left in the engine until the following oil change
  • Safe to use in all types of engine oil
