Cooling Systems

Can I mix different colour coolants?

No, coolant colour alone does not specify the chemical technology of the coolant. It is important to note that when coolants of different technology are mixed the performance is compromised.

Do I need to use Radiator Flush and Clean in my cooling system?

While not essential we recommend using Radiator Flush and Clean (R40) to remove insulating built-up sludge and residue before changing coolant in any cooling system.

Do you guarantee my cooling system won't corrode?

Using the correct type of coolant is essential. The Nulon Lube Guide can provide a guide to you coolant requirements. If directions of use are followed correctly Nulon coolants will protect the system from corrosion for the recommended life of the coolant.

How do I change my coolant?

We show you how to change your vehicle's coolant in this easy step by step video. 

 

Nulon shows you how to change your vehicle's coolant in an easy step by step process. 
All you need to do this is: car jack, jack stands or ramps, screwdriver, socket or spanner, drain plug washer, oil drain pan, some rags, container for the used coolant, Gloves and Nulon Long Life Coolant.

I have had a bottle of coolant in my garage for a few years. Does it have a use by date?

Nulon coolants do have a shelf life. Nulon Green Premium Long Life Coolant 100% Concentrate (LL) and Green Premium Long Life Coolant Premix (LLTU) have a shelf life of three years. Red Premium Long Life Coolant 100% Concentrate (RLL), Blue Premium Long Life Coolant 100% Concentrate (BLL), Multi-Vehicle ONE Coolant 100% Concentrate (ONE) and Super Heavy Duty Diesel Coolant 100% Concentrate (HDDC) have a shelf life of five years.

Is coolant poisonous?

Yes, coolants that contain ethylene glycol are poisonous. If ingested it affects the central nervous system and can cause death. Nulon adds a bittering agent to its coolants that contain ethylene glycol to prevent accidental ingestion from children or pets. Help can be sourced via Poisons Information Centre : Australia phone 131 126, New Zealand phone 0800 764 766

Is distilled water suitable to add with Nulon coolants?

Yes it is suitable but often more expensive than demineralised or deionised water.

Is rain water suitable to add with Nulon coolants?

It is best to use deminalised or deionised water. Uncontaminated rain water is OK but if collected from roofs and gutters it can contain impurites which may affect coolant performance. Metal roofing materials, concrete roof tiles and tanks, dirt and dust, all contaminate rain water. These conatanimants have an adverse effect on your vehicle cooling system.

Is tap water suitable to add with Nulon coolants?

Tap water quality can vary widely depending on your location. It is best to use demineralised or deionised water (Radiator & Battery Water (RCSW)), as tap water contains chemicals and minerals which can affect the performance of the coolant. 

The coolant I purchased has changed colour in the bottle. Has it gone off ?

No, it is OK to use. Dye is added to coolant for identification purposes. The dye used to colour the coolant, green, red, etc can be affected by sunlight and age but this does not effect the performance of the coolant.

What are IAT, OAT, HAT coolants?

These abbreviations refer to the technology used in the corrosion protection component of a coolant. IAT is Inorganic Additive Technology (often termed Conventional Technology), OAT is Organic Additive Technology, and HAT is Hybrid Additive Technology. To determine the best technology option and the preferred coolant for your car refer to the Nulon Lube Guide instore or online.

What is ethylene glycol?

Ethylene glycol is a product used in automotive coolants to give the coolant a lower freezing point and higher boiling point. This allows vehicles to operate in sub zero climates and also allows engine coolants to reach higher temperatues before boiling.

What is meant by Type A and Type B coolant?

In 1977 an Australian Standard was created to help regulate the quality and performance of automotive coolants in the Australian passenger car and light commercial market. The current standard is known as AS2108-2004. Type A coolants are antifreeze/antiboil coolants with corrosion inhibitor that comply with the requirements of this standard. Type B coolants are coolants with corrosion inhibitors only that comply with the requirements of this standard.

What is the difference between soft, demineralised and deionised water?

Soft water, demineralised and deionised water are terms used to describe water which has low levels of dissolved mineral salts and ions of such metals as calcium, iron, or magnesium.

What ratio of coolant do I need?

This depends on the type of coolant your car requires and the climate extremes that your vehicle will operate in. Consult the Nulon Lube Guide for the suitable coolant type, consult your vehicle handbook and follow directions of use on label to determine the required ratio.

What type of coolant suits my car?

The best answer to this question can be found in the Nulon Lube Guide, also available in store.

Where can I dispose of old coolant?

Contact your local waste facilities or environmental protection agency. Used coolants can contain environmentally unfriendly materials that have originated from the engine cooling system and need appropriate disposal. Do not drain used coolant onto the ground or into storm water.

Why do I need antifreeze coolant when I don’t live in a cold climate?

Most modern cars run their cooling systems at temperatures close to 100 degrees celsius. The bonus of using the antifreeze chemical (glycol) in coolant is that it also raises the boiling point. This gives protection against localised or hot spot boiling which can cause engine damage.

Why does my car need coolant?

Internal combustion engine generate large amounts of heat. "Coolant" simpy means a liquid that provides  temperature-transferring properties. In an automotive cooling system it is required to transfer heat from the engine whilst protecting the engine from corrosion (i.e. rust) and erosion which can be caused by fluid movement. Many automotive coolants also have added chemicals to extend the operating temperature range of the fluid. These are known as antifreeze/antiboil coolants.

Will Radiator Stop Leak stop a coolant leak in my car?

Radiator Stop Leak (R50) is a product that will seal minor leaks in a vehicle cooling system. This product should only be used as a temporary repair. You should have a mechanic check and repair the problem at the first available opportunity.

Engine Issues

What is PTFE (commonly called Teflon)?

Polytetrafluoroethylene (Telfon) is an inert substance with an extremely low co-efficient of friction that has been used for many years as a friction and wear reducing additive.

What Nulon engine treatment suits my vehicle?

This depends to the fuel type (petrol or diesel) and also the age and mileage on the vehicle. Worn Engine Repair (E10) for high mileage engines with some wear, Modern Engine Treatment (E20) for engines in good condition, Pro-Strength Extreme Performance Engine Treatment as a long term treatment. Diesel engines should use Pro-Strength Heavy Duty Diesel Engine Treatment.

Can I add more than one Nulon product to my engine?

It is recommended to only use one Nulon engine product at each oil change.

Can I use Nulon engine treatments in my boat or motorbike?

Nulon engine treatments can be used in used in four stroke boat and four stroke motorbike engines but at appropriate dosage rates (see labels for details)

Do engine treatments affect synthetic oils ?

I have purchased Nulon Engine Oil Flush. Do I add it to my oil before or after I change my oil?

Engine Oil Flush (EOF) or Pro-Strength Extreme Oil Flushshould be added to your engine oil just prior to changing your engine oil and directions of use on the rear of the bottle must be followed. The vehicle must not be driven when Engine Oil Flush is in the engine. 

If I use two bottles will it work faster or give a better result ?

No, all engine treatment products should only be used as per dosage recommendations as per directions. We would also recommend to not use more than one additive in an engine at one time.

My car blows smoke in the morning, what product should I use?

White exhaust smoke on morning start-up is generally caused by leaking valve stem seals. Engine Stop Leak (ESL) would be the best product to use to reduce this smoke.

My car is leaking engine oil. What can I do?

Nulon Engine Stop Leak (ESL) is an additive that can rejuvenate elastomer type engine seals that have hardened or shrunk. "rear main" and "timing cover" seals are typical areas for external oil leaks.

My car uses a lot of oil and blows smoke constantly. What can I do?

When an engine uses oil and blows blue smoke constantly, it indicates excessive piston or ring wear. Stop Smoke (SS) can reduce the amount of oil that passes worn rings and causes exhaust smoke.

My engine is using a lot of oil, should I run a thicker oil to reduce this consumption?

Running a very thick oil can sometimes cause issues in modern engines. An area that is often overlooked when oil comsumption is a problem is hardened valve stem seals. Oil will bypass hardened seals and allow oil into the combustion chamber via the valve stems. Consumption as high as one litre per thousand kms can be caused by valve stem seal leakage. Nulon Engine Stop Leak (ESL) can rejuvenate hardened valve stem seals and should be used before moving to a thicker engine oil.

My engine makes a tapping noise (tap, tap, tap/tick, tick, tick) on cold start up, this noise stops after a few kilometres of driving. Can a Nulon engine additive fix this noise?

Most modern engine use hydraulic valve lifters which can cause tapping noise on start-up if they are sticking or have blocked oil passageways. Nulon Lifter-Free and Tune-Up (LFTU) can remove carbon and oil sludge deposits when added to your engine oil. 

What do I do if I add the engine additive to my fuel tank by mistake?

Most Nulon engine additives will dilute with fuel, it is suggested to fill tank ASAP to dilute the product. Stop Smoke (SS) may block fuel pump pick-ups, if this product is accidently added to the fuel tank we suggest draining the fuel tank.

What if I accidently place a fuel treatment in my engine oil?

It will dilute the engine oil, effecting its viscosity and ability to protect vital components. We recommend replacing engine oil and filter before driving.

Will Nulon fuel treatments give my vehicle better fuel economy?

By cleaning fuel system deposits Nulon fuel treatments can restore fuel economy that has been lost due to fuel system deterioration. Nulon octane boosters can improve fuel quality which can lead to increased fuel economy.

Will octane booster make my car go faster?

It will increase the octane rating of the fuel but the increase in performance will be controlled by the engine management system.

Lubricants

Are there different types of synthetic oil?

Engine, gearbox, and transmission oils are blended from base oils. These base oils are categorised into Groups by the API Base Oil Classification system. If the automotive field Group III and Group IV base oils are marketed as synthetic.

Can I use a diesel engine oil in a petrol engine and vise versa ?

Most diesel engine oils carry a higher specification rating than petrol engine oils and vehicle manufacturers often specify a diesel engine oil be used in a petrol motor. This does not work in the reverse, petrol only engine oils cannot be used in diesels. Some engine oils carry both petrol and diesel specifications.

Can SYNATF be used in any automatic transmission?

No. Nulon Full Synthetic Multi Vehicle Automatic Transmission Fluid (SYNATF) covers a large number of vehicle applications but there are some vehicles which cannot use this fluid.

Is an API GL5 gear oil better than a API GL4 gear oil?

No, the API GL5 rating does not supercede or cover the GL4 rating. It is important to follow the gearbox or diff manufacturers recommendations and use the correct GL rating.

Is synthetic oil better than mineral oil?

Synthetic base oils have a number of advantages over mineral base oils. The uniformity of the synthetic oil molecules improves the thermal stability and reduces oxidation of the oil. Controlled molecular structure also results in lower volatility and a more stable vicosity over the life of the oil.

My engine oil discolours quickly, is that a problem?

All engine oils contain detergent and dispersant additives which remove contaminant build-up inside your engine. When new oil is added to an engine these additives strip away build-up and hold the contaminant in suspension so it can be removed when the oil is drained, this does discolour the oil.

What are low SAPS oils?

Low SAPS oils contain low levels of sulphated ash, phosphorus and sulfur. These oils are often recommended for diesel engines that incorporate exhaust emission control devices (DPF, TWC).

What are the benefits of AN over conventional base oils?

There are a number of important performance characteristics AN have over other base oils and these include:

  • Increased thermal and oxidative stability
  • Increased hydrolytic stability. AN does not attract water like ester based oils making it ideal for vehicles running E85 or other high performance fuels.
  • Excellent additive solvency.
  • Excellent seal compatibility.
  • AN is less polar versus ester, therefore will not compete with additive for metal surface attention.

What are the benefits of PAO over mineral based oils?

PAO offers a number of benefits over mineral based oils including:

  • Shear stable under extreme operating conditions
  • Enhanced wear protection
  • Greater oxidative stability
  • Excellent protection under high heat and high load applications
  • Excellent low-temperature viscosities
  • Extremely high viscosity index

What does Group IV and Group V base oils mean?

All engine lubricants start life as a base oil and fall into either Group I, II, III, IV or V base oils.  Group I and II base stocks are typically ‘less refined’ and form the basis of Mineral or semi synthetic base oils.

Group III base oils are widely considered to be synthetic while group IV an group V base oils are 100% fully synthetic and offer the highest level of lubricant protection and performance. Nulon Racing oil is blended using group IV and group V base oils.

What does SAE, API, ACEA stand for?

SAE is the Society Of Automotive Engineers (USA). The SAE rating of an oil is a measure of its viscosity (eg 20W50).

API is the American Petroleum Institute. The API rating of an engine oil covers the performance rating of the oil (e.g. SM for petrol, CF for diesel).

ACEA is a European industry body up of European vehicle manufacturers. The ACEA rating of an engine oil of covers the performance rating of the oil (e.g. A3/B3, C3).

What is a Diesel Particulate Filter and why does it effect the engine oil requirement for my engine?

A Diesel Particulate Filter (DPF) is an emmission control device fitted to the exhaust stream of some modern diesel engines. It traps any soot that is present in the exhaust gases. All engines allow some amount of engine oil into the combustion chamber through cylinder lubrication, breathers etc. This oil is burnt and enters the exhaust stream. It is important to use oils with the correct levels of additive to prevent blockage of the DPF. Lows SAPS oils are generally recommended for DPF fitted vehicles. Consult your vehicle handbook or the Nulon Lube Guide for correct oil selection.

What is a hypoid gear oil?

A hypoid gear oil is a lubricant that is designed to operate effectively with hypoid gear designs. Most gearboxes and differentials use hypoid gear designs and the lubricant must contain EP (extreme pressure) additives to prevent wear between the sliding surfaces of a hypoid gear mesh.

What is Alkylated Naphthalene (AN)?

AN (Alkylated Naphthalene) is a 100% synthetic base oil stock well suited for lubricants in a variety of automotive and industrial applications. AN is particularly suited for use as a base stock in synthetic lubricant applications that require high stability under extreme operating conditions. 

What is Moly DTC?

Nulon engine oils contain Moly DTC. This unique, state of the art, engine oil additive offers huge reductions in friction to provide improved fuel economy and provide optimum wear protection.

What is Poly Alpha Olefin (PAO) ?

Poly Alpha Olefin or PAO is a 100% synthetic base oil stock used in the production of high performance lubricants. PAO’s typically have a higher viscosity index than mineral oils and better oxidative stability- i.e.they are less likely to breakdown.

What is the difference between your Nulon hydraulic fluids, they all list similar specifications?

Nulon hydraulic fluids do carry similar performance specifications but do vary in viscosity. ISO32, ISO46, and ISO68 are a measure of the fluids viscosity, the higher the number the thicker the fluid. Consult your machinery handbook to determine the viscosity recommendations of the equipment manufacturer.

Where can I dispose of used oils?

Contact your local waste facilities or environmental protection agency. Used coolants can contain environmentally unfriendly materials that have originated from the engine cooling system and need appropriate disposal. Do not drain used coolant onto the ground or into storm water.

Which oil suits my vehicle?

Nulon provide lubricant recommendations in their on-line Lube Guide.

Why are engine oils getting thinner?

The main drive behind the use of thinner engine oils is fuel efficiency. The thinner the oil the less drag on internal components and also results in reduced energy loss caused by the oil pump etc.
